2.2.7 CTS Links
JP76 and JP77 when fitted provide a V28 level CTS output on pin 15 for
channel 1 and channel 2 respectively. If a 1 to 1 fully connected cable is
used with an X21 interface, these links should be removed; otherwise
they can be left in.
2.3 Command Terminal Access
Software configuration and control of your KBU 64 is achieved via the
COMMAND port on the rear panel, using a local terminal, modem or PC.
The port is configured as a physical DCE, the default terminal standard
is VT100, with data transfer at 9600 bit/s, no parity, 8 data bits, 1 start
and 1 or 2 stop bits. This data rate can be altered by software command.
PCB shorting link options are used to select between chassis
earth/ground and signal ground (through pin 1 of the 25-pin connector).
RTS/CTS loopback link options are also provided.
Refer to section 12 for details of the factory default and user definable
settings available.
