The SSD002 Slow Scan Data Module handles a variety of slow scan sources such as those from computer COM ports, security card readers, industrial controls and other data communications. The SSD002 has two I/O channels, each of which can be assigned independently to any data channels on the network. Dismountable phoenix style connectors are used.

The I/O format is software selectable for RS232, RS422, and RS485 (2 & 4 wire) with and without standard terminations. Available user selectable data rates are available for: 38.4 kb/s, 76.8 kb/s, 153.6 kb/s and 307.2 kb/s.

The SSDSC4 module provides four input sensing dry contacts and four output contacts used to interface with external devices such as alarm panels or door micro switches.
