Important: When wiring the power connector supplied with the radio, be sure to observe the
proper polarity markings on the power connector. Wiring the connector incorrectly can cause
serious damage to the radio which will not be covered under the ProSoft warranty.

The Power Connector (ProSoft part number 002-0116) is shown on the left. Note
the + and – polarity markings. The connector lever (ProSoft part number 357-

0061) shown on the right is helpful for installing wires into the spring-loaded
contacts inside power connector.

To use the connector lever, insert it into the connector as shown:

Press down on the installation tool to use it as a lever to open the connector’s
contacts to insert a wire. A properly-wired power connector is shown:

The configuration webpage is used to configure and manage the ICX35-HWC.
First-time setup must be performed over a wired network, where provider-specific
cellular configuration details are configured. Once initially set up, you can access
the webserver over the LAN and cellular networks (unless LAN access is
disabled).

Key benefits of the web-based configurator include:

 Login and device parameter configuration
 Network setting adjustments
 Security setting maintenance
 Event reporting update
 Firmware updates

7 In the ICX35-HWC configuration webpage, click APPLY. The page

automatically redirects to the new IP address if the IP address is changed.

8 Reset your PC back to its original IP address. This IP address should be on

the same subnet as the ICX35-HWC.

9 Close your browser and open a new session. Enter the new IP address of the

ICX35-HWC to access the configuration web page. Add :8080 to specify the
correct port (192.168.0.250:8080).

2.3 Connecting to Your Cellular Provider

The ICX35-HWC supports 3G GSM/GPRS and 4G LTE (where applicable)
networks. It uses your cellular provider as an ISP (Internet Service Provider) to
connect to the Internet. All cellular service connections require a Subscriber
Identity Module (SIM) to be installed in the ICX35-HWC. This includes
connections to CDMA based services like Verizon (previously did not require a
SIM). Contact your service provider to obtain a SIM.

2.3.1 Connection Using GSM/GPRS

The Subscriber Identity Module (SIM) in the ICX35-HWC is a smartcard that
securely stores the key identifying a cellular subscriber. Generally, you will only
need to install a SIM once in the life of the cellular gateway - and it may be pre­installed by your ProSoft Technology Representative.

Important: Your cellular provider must provide the Public APN and IP address of the SIM card.

AT&T Users: For SMS texting functionality, you must power up the ICX35-HWC with the SIM

installed within 72 hours after AT&T activates the SIM card.

The SIM card slot is located on the front of the cellular gateway.

1 Remove the SIM Card Slot cover by removing the two screws holding it into

place.

2 Insert the SIM card into the ICX35-HWC and cycle power. The SIM card is

read by the ICX35-HWC upon boot up.

3 Re-attach the SIM Card Slot cover.

4 Enter the APN (Access Point Name) in the Configuration > Basic Module

Settings. The APN is provided by your cellular provider.

5 After the ICX35-HWC reboots, it establishes a link to your cellular provider

network, also called registering on the network, and then receives an IP
address.

6 When the ICX35-HWC receives its IP address from the cellular provider, a

connection to the Internet or the cellular network is also available for
computers or other devices to connect directly to the ICX35-HWC.

7 The GSM network information is now displayed on the Status web page.

2.3.2 Connection Using CDMA

1 When the ICX35-HWC is powered on, it automatically searches for cellular

service using CDMA-based cellular technology.

2 The ICX35-HWC establishes a PPP (Point-to-Point Protocol or "dial" up

connection) link to the cellular network, also called registering on the network,
and receives an IP address.

3 When the ICX35-HWC has received its IP address from the cellular provider,

a connection to the Internet or the cellular network is also available for
computers or other devices to connect directly to the ICX35-HWC.

4 The CDMA network information is now displayed on the Status web page.

2.3.3 SIM Card Security

To protect a SIM card from others using it for phone calls or cellular data, a SIM
PIN can be used. When a SIM PIN is used, the SIM card will automatically lock
upon an ICX35-HWC reboot. The PIN protection enablement, PIN (Personal
identification number), and PUK (PIN unlock key) codes are saved on the SIM
card. Replacing the SIM card will require a reconfiguration of the SIM settings.

Most mobile devices offer SIM PIN protection. At startup, if the PIN security
function is active, the user must enter a 4 to 8 digit PIN to enable the ICX35­HWC’s non-emergency functions. The user can save the PIN code in the
configuration in an encrypted format.

clicking the Save PIN box.

5 When ready, click the APPLY button to apply the changes.

6 When successful, the following message displays:

7 To disable this feature, select Disable from step 2 above and continue

through the steps.

Important: If the wrong PIN Code is entered and submitted more than three times, the SIM card
becomes blocked. (Notice the number of Remaining tries in the top right corner of the SIM Settings
area). The SIM card can be unblocked by entering a PUK code, provided by the service provider
(Example: AT&T). The next section discusses the unblocking process.
When the SIM card is blocked, you will not be able to access the ICX35-HWC configuration
webpage via the WAN connection. You can connect via the LAN (Ethernet) port until the SIM card
is unblocked.

2.3.5 Unblocking a SIM Card

If the wrong PIN Code is entered more than three times, the SIM card becomes
blocked. During this time, ICX35-HWC WAN (cellular) connectivity is disabled.
The SIM PIN status shows “SIM Blocked” on the STATUS > SYSTEM STATUS
webpage (WAN section). You can unblock it by entering the PUK code assigned
to the SIM card by your service operator.

1 To unblock the SIM card, click the UNBLOCK link from the STATUS > SYSTEM

STATUS webpage (WAN section).

2 The link takes you to the CONFIGURATION > BASIC webpage (SIM Settings

section).

3 Contact your service provider to provide you with the PUK code. You will

need the phone number that is assigned to the SIM card.

Important: It is recommended to keep the PUK written down in a safe place from the device.
Entering an incorrect PUK code ten times in a row will permanently lock the SIM card, requiring a
new one.

4 Once you obtain the PUK code, enter the PUK Code and a New PIN Code.

5 Click APPLY.
