These Extron switchers can be slaved to
the System 7SC:
• System 8 PLUS • SW4 AR MX HV
• System 10 PLUS • SW 6 AR MX HV
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.
