Power Code (PC) | F | C |
TX
■Accesses the data stream being received from the local loop
RX
■Accesses the data stream being transmitted to the local loop
RS-232 DB-9 CONNECTOR
■Used to access performance monitoring data, perform loopbacks and provision units via VT100 emulation software such as Hyper Terminal – Private Edition and ProComm Plus.
■Provision terminal port as follows:
Data Rate — 19.2 kbps
Asynchronous Data Format — eight data bits, no parity (none), one stop bit
■When using a PC with terminal software, be sure to disable any power saving programs.
