Expression 2/3 Line Remote Macros
The Expression 2.3 Line consoles provide eight remote macro inputs through the 25-pin connector on the back panel labeled Remote Go. A user-supplied remote device connects to the console via a 24 AWG, aluminum-shielded, multi-conductor cable with one twisted pair designated for each switch (Belden 9507 S-R PCV Insulated or Alpha 5477 80 Deg. C 300 V PVC). The cable connector at the remote device will vary depending on the device itself.

The Three Ways to Wire

(#1 is most typical way of wiring. Remote Macro also requires ribbon cable and chips in Facepanel PCB.)

1)Connect all -Macro pins (pins 1-8) to ground (pin 10) and switch the leads connecting the +Macro pins (pins 14-21) to +12 Vdc (pin 24)

2) Connect all +Macro pins (pins 14-21) to the +12 Vdc pin (pin 24) and switch the leads connecting the -Macro pins (pins 1-8) to the ground (pin 10).

3)Provide your own power supply that generates a 12 Vdc potential between the +Macro and -Macro pins and switch either of these leads.
