These units are intended to provide enhanced conflict and voltage monitoring for traffic controller assemblies with additional capabilities for broader fault coverage and diagnostic troubleshooting. The SSM-6LE and SSM-12LE units include a Full Intersection Liquid Crystal display (LCD) along with an RS232 port which is used to communicate with a Personal Computer using EDI ECcom software. Monitor status, event logs, and Signal Sequence History logs are stored in nonvolatile memory for diagnostic and archival purposes.
