FAQs about the CTM-200
Browse the sections below to find answers to commonly asked questions about the Chameleon CTM-200.
- The power LED is blinking. What does this mean?
- The LED labeled GPS is blinking on my CTM-200. What does this mean?
- The orange 3G light is blinking on my CTM-200. 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 CTM-200 is connected to my vehicle and it's wired to stay on when my ignition is off, but when I start my car, the CTM-200 power goes off and then comes back on again. Why?
- While logged into the CTM-200 remotely via Telnet or the embedded Web server, I restored the CTM-200 configuration to its factory defaults. Now I cannot remotely access the it. Help.
If the power LED is blinking, this means that the CTM-200 is in standby mode. This is the lowest power state of the CTM-200 (< 2 mA). The CTM-200 is in this state because the white "ignition sense" wire is most likely disconnected. To get the CTM-200 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 CTM-200's GPS LED light is blinking, this means that the CTM-200 has not acquired a valid GPS fix. This can be caused by the GPS antenna not being connected to the CTM-200 or the GPS antenna is positioned in an area without clear visibility to the sky. The embedded GPS within the CTM-200 requires a fix on a minimum of 4 satellites before the LED will stop blinking. When the CTM-200 first powers up, the GPS light will blink for about 1-2 minutes.
When the orange 3G light is illuminated, the CTM-200 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 CTM-200 has not negotiated a connection with the wireless network. For a cellular connection this could mean either there is no cellular coverage at the CTM-200's location or the CTM-200's cellular device/module has not been activated with the carrier.
5. The CTM-200 is connected to my vehicle and it's wired to stay on when the ignition is off, but when I start my car, the CTM-200 power goes off and then comes back on again. Why?
The CTM-200 is designed to operate with voltages from 5.5 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 CTM-200 will reset. To allow the CTM-200 to operate to voltages as low as 6 Volts, the supply voltage threshold setting needs to be configured to a lower voltage (refer to cmd pwr vcct for details).
6. While logged into the CTM-200 remotely via Telnet or the embedded Web server, I restored the CTM-200 configuration to its factory defaults. Now I cannot remotely access the it. Help.
The factory default configuration for the CTM-200 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 CTM-200 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 CTM-200. This can be performed via Ethernet (i.e. local Telnet or local embedded Web server access) or via a serial port cable.
Restoring the CTM-200 configuration to its factory defaults should not be performed while remotely accessing a CTM-200.
