OFTWARE WITCHES
The MicroCSU/DSU Front Card has an internal control port that allows software
configuration. Control port signals are carried to each card in the rack along the
power bus board inside the rack chassis. Access to all rack card control ports is
provided by a single control card.
Accessing the Software Control Port
Once you have set each Card's address, plugged each front card into the rack
chassis, and properly installed the control card, you are ready to access the Main
Menu. Follow these steps:
1. Connect the serial RS-232C port of a VT100 terminal (or similar RS-232 DTE
with terminal emulation) to the EIA-561 control port on the control card.
2. Power on the terminal and set its RS-232C port as follows:
9600 baud
8 data bits, 1 stop bit, no parity
local echo
CR=CR/LF on inbound data
ANSI, VT100 emulation
3. Press [CTRL+B] on the terminal, then enter the address of the card you wish
to configure, and press [RETURN].
Do not use the universal address [99]. Configure only one card at a
time.
The Main Menu should then display on the terminal screen.
