Please contact to identify the product that best meets your needs.
Where do I get power supplies and cables?
In the North American market, the power adapter is supplied with the iPocket232 device. European and UK power supplies (9 v, 500 ma) for the iPocket232 and Ether232DUO may be substituted. For other types of power supplies, iPocket232 will supply the required information to purchase power for our devices.

Basic cables (e.g., null modem, Ethernet) are available from any local electronics supply or computer store. One thing to remember is the iPocket232 is a DCE serial device (versus a PC, which is a DTE serial device) so whatever serial cable you would use to connect the PC, you would need the opposite cable to connect the iPocket232. For example, if you use a straight through cable now to connect to the PC, you would need a null modem serial cable to connect the iPocket232 and vice versa.

How do I determine if my iPocket232 unit needs repair?
First, disconnect all cables from the unit including power, then reconnect only power, wait 4-5 seconds for the reset of device and review what the LEDs are doing.

The typical issues are as follows:

  • if both the Serial Transmit and Serial Status are on and stay on, then you are in firmware download mode.
  • if both the Serial Transmit and Serial Status flash together in a sequence (i.e. on…off…on… wait…on…off…on…wait), then the unit is stuck in boot-up sequence; or
  • if the Link LED is on solid or flashes (with no Ethernet cable connected to the unit), that is not a good sign and unit will have to be RMA’d.

If your unit is not working (and you have performed the tests listed above), you need to obtain a new unit. Please to get a new unit.

Where do I find the IP addresses to program the box with?
The Internet Protocol (IP) address is the unique address assigned to the host (computer) interface, or in this instance, the iPocket232 device. Every IP enabled device must have either an assigned address (static IP) or an address available from a pool (dynamic IP) to be able to communicate with other hosts over TCP/IP.

A static IP address can be obtained from your network administrator. A dynamic IP address will be assigned by the host computer. This IP address is only valid for the duration of the “call”.

How can I mount the unit on the wall?
The iPocket232 device is a compact, lightweight unit that can be mounted on the wall using screws or Velcro strips. Although the iPocket232 device can be mounted in any direction, it is recommended that it be mounted with the cables coming out the top for ease of reading the indicator lamps.
When do you need to set a Gateway value in the iPocket232 device?
The Gateway address will need to be set if the data transmission is to go outside the LAN. A Subnet Mask will also be required. See your network administrator for this information.
How can I access/monitor my iPocket232 device remotely?
There are three remote management tools available for iPocket232’s products.

Remote Access via NetVu

iPocket232’s latest products are all available on NetVu, iPocket232’s network management server.

Remote Access via Telnet

Information on Remote Access via Telnet is available from the Telnet Help Guide.

Remote Access via SNMP

iPocket’s products support SNMPv2c. SNMP (Simple Network Management Protocol) is a protocol for viewing network statistics and settings. An SNMP management system consists of a manager (remote) and an agent (iPocket232 device) using UDP as the communication protocol. The iPocket232 SNMP agent supports MIB-II, and allows GET (read) commands for gathering information, SET (write) commands for managing how the information is gathered, and trap (notification) generation for alerting the Network Manager when selected or unusual events occur. For details on configuring the SNMP feature refer to the SNMP Settings and Compliance Help Guide.

Serial Connectivity
Can I power my device through your box, or can I power your box through my device?
Yes, but this is a non-standard feature which must be specifically requested by the customer.  With the iPocket232, it is part number PE000700 (powers 5v devices) or PE000701 (powers 9v devices).
If my server cannot keep up with the data stream coming from the serial port, how can I do flow control?
The port speed is easily reconfigured to decrease (or increase) the communication speed between the iPocket232 device and your server. We offer both software and hardware flow control in our devices. Hardware flow control toggles the serial port handshaking lines to the remote system to tell it when to start/stop traffic flow in order to regulate the throughput.

Software flow control transmits two special control characters called XON and XOFF (0×11 and 0×13) in the data flow to the remote system to perform the same function. The choice of which one to use is dependent on what is available in the remote system. Note however that if software flow control is used, the user must be certain that none of the data characters can ever be 0×11 or 0×13, otherwise these will be interpreted as flow control characters and will completely confuse the system. This is the one big drawback of using software flow control in any environment.

Do I need any special splitter to connect the box to an existing LAN drop?
No, you only need an available Ethernet port on your LAN, as well as the appropriate addressing for the same.
What’s the difference between client, server, and tunnel mode?
In Client mode, the unit connects with the configured host (hosts) only and does not accept incoming connections. In Server mode, the unit could accept calls from “client’s” nodes. In Tunnel mode, the unit acts as the gate, accepting data in one format (serial data) and sending information to a single host using the specified IP addresses and vice versa.
What is the difference between Transparent UDP and UDP ?
UDP (User Datagram Protocol) is the network transport mechanism (as opposed to TCP). “Transparent” is the protocol we run to packetize data from the serial port to be sent on the network. You have a choice between “transparent”, “terminated”, “Telnet”, and “Com-Port Control”.

The protocol allows you to configure the iPocket232 unit to group the serial data in a specific way. For example, “transparent” waits for a maximum packet size or a specified inter-character delay before transmitting the collected data over the network. “Terminated” mode looks for certain characters and sends a packet when one of those characters is received.

What is serial tunneling?
Serial Tunneling involves the use of two iPocket232 units configured to work as peers. These units simulate a direct serial cable between two intelligent devices, enabling them to communicate as if the network were not present.
How do I set the Comport configuration?
Your iPocket232 device needs to be set to TCP-server in order to work (default is Telnet Port).

Network Management Server
What do the different colors on Network Management Server mean?
The main Reporting Screen has been designed to identify and prioritize devices with potential issues that require action. Products are displayed in different colors to allow for simpler identification. They are prioritized from top to bottom as follows:

Red – Devices that have failed to properly implement commands or that have lost contact with Network Management Server  are displayed in red and placed at the top of the display.

Black/Bold – Products that have been enrolled, issued commands and are ready for deployment show as black bold.

Green – Devices operating in a normal fashion and reporting to Network Management Server  properly are shown in green.

Purple – Unregistered devices that contact Network Management Server  before being enrolled could be at risk if at a merchant site and so are displayed as a higher priority.

Blue – Inventoried devices are displayed in blue at the bottom of the screen.

Products that are bolded have been issued commands but Network Management Server  is still awaiting contact from that device. These devices are prioritized just after alarmed (Red) devices. New devices that are issued commands from Inventory through the ENROLL PRODUCTS process will change to bold black once the Update button is clicked and the changes are accepted.

What other options do I have to select a product or group of products?
Search by Serial #: Search for particular devices or groups of devices in the “Search by Serial #” dialog box. Just enter any part of the device’s Serial # and click on Search. The report will list all devices containing the searched string on the page.

Choose a Report: Clicking on the Choose a Report dropdown will allow you to filter the report to show only Alerts (Red devices and Bold devices), only functional devices (Green) or only device in Inventory. The Audit report can also be chosen.

Report by Merchant: The column heading for Merchants is a drop down list that allows you to display only the devices for the particular Merchant chosen.

Sorting by Column: Clicking on the column headings will sort the rows in alphabetical order. Click again to switch the order (ascending /descending). To return to the main screen from a specific sorted view, click the Back button on your browser.

Returning to Main Reporting Screen: To return to the main screen from a specific merchant view, either choose All Merchants from the Reporting drop-down list, click on Reporting option on the NetVu menu bar or click the Back button on your browser.

What is the difference between Internal and External in the IP Address column of the Reporting screen?
The Internal IP/External IP drop-down in the title of this column allows you to choose between displaying the Internal or External IP Address of the devices listed. Internal IP is the IP Address on the WAN Port of the device and External IP is the IP Address of the gateway router. Both IP Addresses are received from the poll messages sent by the device to Network Management Server .
How do I find out who made a certain change on a product or when a change was made?
Network Management Server maintains a comprehensive log of all activity on the system within its Audit Log. Users are able to view activity within their account using this report. The default view displays the latest 24 hours of activity. Other options can display the Last week, Last month, All activity or to search on activity of selected devices by entering a portion or the entire Serial # in the ‘By serial #’ dialog box and clicking on Search.
What do the different columns on the Reporting screen display?
Location: Displays location or store specific information such as store number that will allow Merchants to differentiate between different devices.

Product: Identifies the type of Product connected to NetVu (i.e. iPocket232)

Internal/External IP Address: The Internal IP/External IP drop-down in the title of this column allows you to choose between displaying the Internal or External IP Address of the devices listed. Internal IP is the IP Address on the WAN Port of the device and External IP is the IP Address of the gateway router. Both IP Addresses are received from the poll messages sent by the device to NetVu.

Serial #: Displays the serial number of the device. This number is unique across all products and allows NetVu to track all activity related to this product.

Version: Displays the current application version on the device as last received from the device by NetVu. Firmware downloads not performed through NetVu will be displayed in the current status in parentheses but will not be displayed within the history window when the selected item is clicked. Note: While application versions are being downloaded into the target device, NetVu will display the version number in a bold, tan color. It is important that the device not be unplugged while the download is in process as this could cause a product failure.

Config File: Displays the latest configuration file imported into the device. Configurations edited by NetVu before being sent to the device will be listed as precidia.cfg. Configuration transfers not performed through NetVu will be displayed as “custom” in the column but will not display within the history. They may however have been captured by NetVu and stored in the Diagnostics column under the configuration file (precidia.cfg), within of the diagnostic files.

Diagnostics/Statistics : The Diagnostic/Statistics dropdown displays the last date that a Diagnostic file or a Transaction Statistics file was received by NetVu.

What commands can I set for NetVu for a particular product?
You can issue commands either by choosing ISO Admin from the menu bar, choosing Edit Product, selecting a MAC ID from the dropdown list and clicking on Continue or, you can click on the product’s Serial # on the main reporting screen. From this screen, you can store the following commands in NetVu to await the next device contact:

Firmware:Select the Firmware # of the application firmware you would like to download into the end device from the drop down list. If the version # you require is not listed, contact at

*Warning* Please note that incorrectly downloading application firmware or not following all steps properly can lead to the end device being harmed beyond repair. The utmost care and diligence is required when selecting this action for a device, particularly an existing device functioning in the field.

Configuration: Select the appropriate Configuration file from the Configuration drop-down list. To add Configuration files to the existing list, please create a configuration template or use an existing configuration file and choose the Save as Template link in the upper right frame of the display.

*Warning*: When selecting a NetVu configuration template to download to the device (all templates for chosen product type will appear in Configuration drop-down list), be careful to verify the IP Addresses of the template file BEFORE shipping to the product as templates will retain IP addressing information. In particular, this could cause issues when the template is set to Static IP Addressing – these settings should be changed to correct addressing before sending to the targeted device.


Contact: The end device will contact NetVu at a predetermined interval (from every 5 minutes to Daily or Never). At each Scheduled Contact, the device will send a complete diagnostic file to maintain a history on the device. The Scheduled Contact interval for new installations should be set to one hour intervals until locations have stabilized, at which time they can be set to a less frequent interval if needed.


Polling: This option allows you to set the interval between polls sent by the device to NetVu. These ‘heartbeats’ allow NetVu to monitor the device and its network path and display and track any connectivity losses. Select how often you wish to poll the device, from 2-15 minutes, or Never. When these selections have been made and all fields are complete, you may click the Update button at the bottom of the page to set these commands in NetVu and await the product’s next contact.


Device Reset Commands: Specific commands can be stored by clicking on the checkboxes associated to the commands on the right hand side of the Command Panel, namely Reset Password, Reboot Device and (set to) Factory Defaults.
