How can I connect my Siemens RDM-PC Remote Diagnostics Module to my computer?

[MacMalachi]

Connecting your Siemens RDM-PC Remote Diagnostics Module to your personal computer allows for remote diagnostics and monitoring of your MXL system. Here's how to do it: First, use the provided RS-232 DB9 cable to connect your PC or laptop to Port 232-A on the RDM-PC. Note that this is a straight-through RS-232 cable. The pin connections are as follows: RDM-PC (Port A, 9 pins, DCE) to PC/Laptop's COM port (9 or 25 pins). Second, connect the 24 VDC power pack to its connector located near Port C on the RDM-PC. Third, connect a standard telephone line to the RJ11 phone socket on the RDM-PC using an FCC Part 68 compliant telephone cord (usually supplied with the device). For a visual guide, please consult the connection diagram in the RDM-PC instruction manual (Figure 1), which illustrates the wiring setup.
