4.8 Configure a Wavecom WM02 modem for use with the RCU
This section describes the configurations for using a Wavecom WM02 at the RCU-01 remote site. It is assumed
the SENTINEL control site will use a Maestro Woomera or other standard V90 modem. (See sect 4.7 for config)
After the SIM card has been fitted, connect the Wavecom modem to a spare serial port on a PC. Fit the antenna,
plug pack and interface lead. Later you will need to fit the mini XLR plug to get power from the RCU-01 with the
external power lead provided. You must also know the PIN code and phone number.
Apply power to the modem and start HyperTerminal on the computer.
Set HyperTerminal for connection direct to the appropriate com port and set it for TTY, 9600 baud, no parity, 8
data bits and 1 stop bit. Set Handshaking to none. (See 3.6 for HyperTerminal instructions.)
At this stage, the modem LED will be steady.
Press return and you should get an OK response. (You may need to send “ate1” to get an echo)
Note that some commands are case sensitive, so enter commands as shown.
Command Comment
at+clck=”SC”,0,xxxx xxxx= 4 digit PIN code. (Disables the PIN code)
