Wireless Mmatrix Proprietary and Confidential 13/20
Connection Procedure
To operate and test this unit, a Power Supply Cable shown in fig.2 and a Serial Cable
will be needed.
Connect the Serial cable terminated with a DB9 connector to a PC.
Connect the power supply cable to a 12V power supply (+12V wire and ignition wire
connected together). The power supply should be capable of handling at least 5A@
12V.
Please note that Communicator 1000C has internal super-capacitors, which
will cause the unit to take up to 1A for the first 20 seconds and then up to 5A
for 15 seconds at initial power up. After the super-caps are fully charged, the
current drops in receive mode under 400mA.
Use a serial modem interface like ZOC, HYPERTEMINAL or PROCOMM PLUS with the
following settings: 115200 baud, 8 bits, No parity, 1 stop bit, Flow Control: None.
Note: Make sure that an antenna is always connected during transmit mode.
This is very important as the PA in the CDMA or the 802.11 cards might be damaged
without a proper load.
Once the Communicator 1000C is properly connected, turn the power supply on and
wait for the unit to boot-up. At the end of the boot-up sequence the user has to log in.
Communicator 1000C supports a large array of AT commands. Here are the more
