Getting Started
Minimum Hardware Interface Required To Get Started
At a minimum, it is necessary to connect the following signals too properly operate the ModemModule:
Table 5-1: Minimum Signals to Operate the ModemModule
Pin Number Name Description
1 GND Ground
2 GND Ground
3 +5V Power Supply
4 +5V Power Supply
6 GND Ground
13 CT106/CTS Clear to Send
15 ON/OFF Power On/Off *
21 GND Ground
24 GND Ground
25 CT103/TX Transmit
28 CT104/RX Receive
30 CT105/RTS Request to Send
* Connected to +5V for example
The serial link signals must be used through the implementation of the serial link level shifter. See “Figure 3-3:
Level Shifter Application Diagram for Serial Link.”
Terminal Emulator Setup
Here below is an example based on the Windows TM Hyperterminal application
(terminal emulator program).
Setup:
1. Go to START – PROGRAMS – ACCESSORIES – HYPERTERMINAL.
2. Start the Hyperterminal software.
3. Give the name of your choice, click on the icon of your choice, and click “OK.”
4. Choose these operating parameter values:
Connect using: direct to COM1
Properties: 115200 bps; 8 bits data; no parity; 1 stop bit; hardware flow control.
5. Click “OK.”
Once Hyperterminal is open and configured, it can be used to send AT commands to the ModemModule.
For assistance in testing your ModemModule, see the examples in the AT Command manual for MultiTech’s
GSM/GPRS wireless modem products (GSM/GPRS AT Commands Reference Guide).
