4.3.1RS-232 Interface

The M100AH uses the RS-232 communications protocol to allow the instrument to be connected to a variety of computer based equipment. RS-232 has been used for many years and is well documented. Generally, every manufacturer observes the signal and timing requirements of the protocol very carefully.

Data Communications Software for a PC: You will need to purchase a software package so your computer can transmit and receive on its serial port. There are many such programs, we use PROCOMM at TELEDYNE API. Once you set up the variables in PROCOMM and your wiring connections are correct, you will be able to communicate with the analyzer. Make sure the analyzer is set up for 2400 baud (SETUP-MORE-COMM-BAUD) and that PROCOMM is set up as described in the "RS-232 Pin Assignments" Figure 4-3.
