Note

TO CONNECT THE INTERFACE CABLES TO YOUR PC

1.On the interface cable (Figure 2-2), connect the Data port connector (labeled “P2-DATA PORT”) to COM 1 or another available serial COM port on your PC.

The Data port transmits packet (PPP) or asynchronous data. You can also use it to send AT commands to the modem. You will see an example of how this works in Chapter 4.

2.On the interface cable (Figure 2-2), connect the Control port connector (labeled “P3-CONTROL”) to COM 2 or another available serial COM port on your PC (or a different PC, if desired).

You can use the Control port to send AT commands to the modem, without interrupting data flow on the Data port. You will see an example of how this works in Chapter 4. The Control port can also receive SMS messages; for information, see Short Messaging Service (SMS) on page 5-17.

If you need to extend the interface cables to reach your PC(s), you can use straight RS-232 9-pin serial cables (with no crossovers). For maximum RS-232 extension cable lengths, see the TIA/EIA-232-E specification.
