Serial Port Connector Pins - Symmetricom SSU-2000e User Manual

Main Shelf Communications Ports
The SSU-2000e main shelf contains four communication ports including:
Two EIA-232 communication ports (Port A, J4; Port B, J5) on the upper front panel
One shielded RJ-45 ethernet connector J3 (10baseT) on the upper front panel for
network connection
One EIA-232 port on the face of the Communications module (Local Port)
The user interface provides various levels of password-protected access for
configuration and detailed performance monitoring and diagnostics. Use either the
ASCII interactive command set or the TL1 user interface to configure and view
detailed performance monitoring, see the SSU-2000e Technical Reference. The
operator assigns an interface type to the remote EIA-232 ports, either interactive or
TL1. When assigned, this information is retained in NVRAM. The Local port on the
Communications module is always in Interactive mode when the module restarts.
