Optional 9-pin TRS RS-232 cable
NOTE: The stereo jack Configuration port (item
o
) protocol can be changed
under SIS command control only (see the
SIS Command, in the “Programming Guide” section to configure all ports
under SIS control).
This port is RS-232 only, with its default protocols as follows:
•
9600 baud
•
no parity
•
8 data bits
•
1 stop bit
•
no flow control
NOTE: The maximum distances from the matrix switcher to the controlling device
can vary up to 200 feet (61 m). Factors such as cable gauge, baud rates,
environment, and output levels (from the switcher and the controlling
device) all affect transmission distance. Distances of about 50 feet (15 m)
are typically not a problem. In some cases the matrix switcher may be
capable of serial communications via RS-232 up to 250 feet (76 m) away.
