MVI to SHIM (RS-232) for an Advant Controller 410
For RS-232 communication, an MVI serial port is connected to a single SHIM in a point-to
point fashion using a single RS-232 cable as shown in Figure 2-2. Each SHIM can be connected
to as many as 8 HART transmitters.
Up to 4 SHIMs can be connected to the MVIs of the PM150.
The MVI is configured:
• 9600 baud, 8N1 (8 data bits, no parity, 1 stop bit), full-duplex.
The 3BUC950040R001 cable (8 meters) between the MVI serial port (RS-232) and the
SHIM-8 has the following pin assignments:
