4. Connect the NETCLOCK/2 to an unused CEC/IMC Manager
COM port. See the cable wiring diagrams that follow.
The NETCLOCK/2 has two RS-232 serial ports. One is an output that
transmits the 26-character ASCII time/date data once each second in
Format 0 or Format 1. This is called the 1/sec interface or the
"REMOTE OUTPUT."
The other port responds to commands from the CEC/IMC Manager by
transmitting a 26-character ASCII time/date data in Format 0, Format 1,
or Format 2. This port transmits the data on the next even second after
receiving an ASCII "T" from the CEC/IMC Manager. This is the T-
CMD or "SERIAL COM" port. Refer to the section of the
NETCLOCK/2 instruction manual concerning NETCLOCK/2 data
formats for additional details.
