Browse the sections below to find answers to commonly asked questions about the Chameleon CTM-15X modem.
- The power LED is blinking. What does this mean?
- The LED labeled GPS is blinking on my modem. What does this mean?
- The orange 3G light is blinking on my modem. What does this mean?
- The power light and GPS LED are solid green but the CELL and 3G LEDS are off. What does this mean?
- The modem is connected to my vehicle and it's wired to stay on when my ignition is off, but when I start my car, the modem power goes off and then comes back on again. Why?
- While logged into the modem remotely via Telnet or the embedded Web server, I restored the modem configuration to its factory defaults. Now I cannot remotely access the modem. Help.
If the power LED is blinking, this means that the modem is in standby mode. This is the lowest power state of the modem (< 2 mA). The modem is in this state because the white "ignition sense" wire is most likely disconnected. To get the modem to power up, add power to the white wire, the simplest way to do this is connect the white wire to the red power supply connection. If the white wire is connected to an ignition circuit, make sure that the ignition is enabled.
If your modem's GPS LED light is blinking, this means that the modem has not acquired a valid GPS fix. This can be caused by the GPS antenna not being connected to the modem or the GPS antenna is positioned in an area without clear visibility to the sky. The embedded GPS within the modem requires a fix on a minimum of 4 satellites before the LED will stop blinking. When the modem first powers up, the GPS light will blink for about 1-2 minutes.
When the orange 3G light is illuminated on the modem, the modem has detected either an EV-DO or HSPA network and is capable of negotiating a high speed network connection. If the 3G light is solid, this indicates that the EV-DO Revision A data rate is available for establishing network connections. If the 3G light is blinking, this indicates an EV-DO Revision 0 data rate or HSPA data rate is available for establishing network connections.
4. The power light and GPS LED are solid green but the CELL and 3G LEDS are off. What does this mean?
If the cell light and the 3G light are not on or blinking, - the modem has not negotiated a connection with the wireless network. For a cellular connection this could mean there is ethier no cellular coverage at the modem's location or the modem's cellular device/module has not been activated with the carrier.
5. The modem is connected to my vehicle and it's wired to stay on when the ignition is off, but when I start my car, the modem power goes off and then comes back on again. Why?
The modem is designed to operate with voltages from 9 to 36 Volts. In some vehicles where the batteries are not new, or temperatures get very low, the vehicle battery voltage can dip below 9 Volts when the engine is "cranked" or started. If the voltage dips below 9 Volts, the modem will reset. Cypress makes a power regulator accessory that eliminates this issue. It connects in-line" with your existing power hookup and will allow the modem to operate to voltages as low as 5 Volts. Contact Cypress Solutions to obtain power regulators for your fleet.
6. While logged into the modem remotely via Telnet or the embedded Web server, I restored the modem configuration to its factory defaults. Now I cannot remotely access the modem. Help.
The factory default configuration for the modem is that remote access features (remote Telnet access and remote Web server access) are disabled. Upon entering cmd factory from a remote Telnet session, or setting and submitting the Restore Factory Defaults option from the Advanced Configuration web page, remote access will be disabled. Subsequent remote log in attempts into the modem via Telnet or embedded Web server will not work.
To restore remote access features, on-site access will be required to enable and save the remote access configuration settings of the modem. This can be performed via Ethernet (i.e. local Telnet or local embedded Web server access) or via a serial port cable.
Restoring the modem configuration to its factory defaults should not be performed while remotely accessing a modem.
