Connecting the Modem to a PC for Modem Configuration

The two most common configurations for connecting the modem to a PC are shown in Figure 6-2. The modem RS-232 port (DB-25 connector) is cabled to a PC serial COM port that uses either a DB-9 connector or DB-25 connector. The connecting cable can be fabricated (See Appendix D) or ordered from Fluke as an option (see Chapter 1).

Configuring the Instrument Modem for Modem Operations

Commands to configure the modem are sent from the PC that is running communications software. The example below uses the Terminal mode that is available on any PC that is running Windows software. Modem operation at 2400 baud is assumed for this procedure, which should be adapted, as required.

1.Start Windows and open TERMINAL on the ACCESSORIES menu.

2.Open the SETTINGS menu and select COMMUNICATIONS.

3.In COMMUNICATIONS, select the following, then use OK to exit to TERMINAL: Connector COM 1 [Typical]

Baud Rate 2400 Data Bits 8 Stop Bits 1 ParityNone

Flow Control None

4.In TERMINAL, enter a few AT <ENTER> character sequences. If the cable connection is correct and the modem has LED indicators, the data send and data receive indicator will blink. If LED blinking is not observed, check the cabling and verify that the correct PC COM port was selected in step 3.

5.Enter the command ATV1 <ENTER>, which gives result codes in English, instead of numbers. For example, the AT <ENTER> characters entered in the last step would display the result code OK.

6.Enter the command ATS0=1 <ENTER>, which configures the modem to answer calls after one ring. [The 0 character of the S0 portion of the command is the number zero.]Observe the result code OK.

7.This completes the software configuration of the modem. Check all modem DIP switches for proper settings. In particular, some modems have a NO ANSWER switch that must be disabled or the modem will not answer calls. Be sure the modem remains powered or the configuration data could be lost. Refer to your modem manual, as required.
