These Extron switchers can be slaved to
the System 7SC:
• System 8 PLUS
• System 10 PLUS
Computer
The System 7SC master connected to a slaved switcher
2. Connect the RS-232 ports of the two switchers. A slave adapter cable (Extron
part number 26-386-01), is required for RS-232 connection. This allows the
master (System 7), the slaved switcher, and the host device to be connected
simultaneously. The RS-232 communication is bidirectional.
The pin assignments for each of the slave cable's three 9-pin connectors are as
follows:
Pin System 7
1 –
2 Tx
3 Rx
4 Tx 2
5 Gnd
6 –
7 –
8 Rx 2
9 –
*Pins 4 and 8 on the host connector must be used for Tx2 and Rx2 only, and
not for other signals in the host system. If needed, disable or disconnect
pins 4 and 8 on the host side.
