Connecting S321-DIN Controllers
The S321-DIN controller provides interface control for access and security devices
associated with a door. The key features of the S321-DIN include:
•
Support for RS-485 bus communications at 4800, 9600, 19,200, or 38,400 (default) (auto
baud rate detection at the controller)
•
Improved RS-485 bus polling algorithm
•
Two-door access control input/output interface
•
One general-purpose input and output per terminal
The S321-DIN can communicate with the P2000 server in one of the following
configurations:
•
Serial communications using a B&B Electronics RS-232 to RS-485 converter (model
485OT9L)
•
IP network communications using the Digi One SP serial-to-Ethernet converter
The following subsections provide instructions for installing the previous converters. For
additional instructions on installing and configuring the S321-DIN controller, refer to its
documentation.
For TCP/IP networking information associated with the P2000 system, refer to the
