2-10 Fiber Matrix 6400 Switcher • Installation
This port is RS-232 only, with its default protocols as follows:
• 9600 baud • no parity
• 1 stop bit • no flow control
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.
• 8 data bits
