LBI-38965SPECIFICATIONS

3.3. CAL OPERATIONAL SPECIFICATIONS

This section outlines the specifications that are unique to the CAL personality. Refer to Figure 4 for the CAL architecture.

NOTE

Before linking a CAL to a System Manager, consult the EDACS VAX/VMS System Manager’s User’s Manual (LBI-38984) to assure that the proper System Manager configuration has been chosen to handle the number of sites to be monitored. Failure to install a properly sized System Manager may result in the loss of logging data during peak periods.

3.3.1. System Manager Interface

The CAL interfaces to the System Manager's DECServer(s) via one or two terminal servers capable of supporting up to 32 independent asynchronous RS-232 serial connections. The ports on the CAL's terminal servers are connected to the ports on the System Manager's DECServers via RS-232 cables.

3.3.2. Protocol Supported

The CAL is capable of communicating with the System Manager using the System Manager-to-Site Controller (SM- SC) and Site Controller-to-System Manager (SC-SM) protocol defined in EDACS Protocol Specification, System Manager/Site Controller Version 1.1.
