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	Host	Slave switcher
1	–	–	–
2	Tx	Rx	Tx 2 (slave to host)
3	Rx	Tx	Rx 2 (host to slave)
4	Tx 2	*Tx 2	–
5	Gnd	Gnd	Gnd
6	–	–	–
7	–	–	–
8	Rx 2	*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.
