P2000 Software Release 3.11
Connecting Serial Controllers to the P2000 Comark
Server Running Software Version 3.11
This document describes how to connect supported serial controllers to the P2000 Comark
server running software Version 3.11. P2000 supports the following serial controllers:
•
S321-DIN
•
D620
•
D600-AP (Version PS 155B or higher)
•
D620-TIU
•
S320
•
P900
If installing serial controllers, you may need the following equipment:
•
Digi® AccelePort® serial adapter board (installed at the P2000 server)
•
PC232 converter (S321-DIN and P900 controllers excluded)
•
B&B Electronics RS-232 to RS-485 converter (model 485OT9L) (S321-DIN controllers
using serial communications only)
Note:
The S321-DIN can use serial communications with the RS-232 to RS-485 converter,
or it can communicate via IP using the Digi One® SP converter. This document covers both
scenarios.
P2000 supports a controller loop configuration in which most serial controllers connect to the
server using a PC232 converter and an AccelePort connector box. See Figure 1 for an
illustration of a P2000 system component configuration with serial controllers.
