SM8/SM16-RC Remote Controllable Microphone Switcher Instructions If your system requires 16 audio zones, you must use an SM8-RC and an SM16-RC switcher. The SM8-RC handles zones 1-8 and the SM16-RC handles zones 9-16. Front panel controls and indicators 1. When powered up, the SM8/16-RC is in remote control mode (the front switches do not work.) If you want to control the switcher manually, press and hold the Zone 1 button until the “Recorder” indicator light goes out. 2. You can now select and deselect Zones by pressing their channel buttons. You can also set the volume of a Zone by adjusting the Level control. 3. To go back to RS-232 control mode, press and hold the Zone 1 until the “Recorder” light illuminates. Note: The SM8-RC will remember what zones were in or out after a power outage. There are two memories; one for local and the other for remote control. Rear panel connections 1. PWR: The SS8/16-RC uses a 12Vdc 1amp transformer. The SS8/16-RC and SM8/16-RC use SEPARATE AC adapters. 2. Audio Out Connector: Connect this to the Audio input of your remote monitoring equipment. 3. Audio In Connector: When using 16 zones of audio, connect the Audio output of the SM8-RC to the input of the SM16-RC using the supplied RCA patch cable. 4. RS-232 Connectors: This is a looping RS-232 input and output. You only need one RS-232 port on your remote monitoring equipment to control up to 4 SM8/16-RC and SS8/16-RC devices. Plug the RS-232 DB9/3.5mm cable into either RS-232 jack on the SM8-RC. Connect the other end of this cable to your remote monitoring equipment. Plug the supplied 3.5mm/3.5mm patch cord into the other jack if using a 16 zone system (see connection diagram). 5. Microphone inputs. Use a single pair shielded #22 wire for microphone cable runs. You can connect any SM1 series microphone to the SM8/16-RC inputs. SM8RC- microphone mixer/switcher. 2 Cascade able units up to 16 channels. Remote control is done via RS-232 8N1 2400 baud. All commands are capital letters or numbers. All commands MUST be followed by a CR character. “MIx” Where x is the microphone you want on. “MOx” Where x is the microphone you want off. “MN” Turn all microphones off. “MA” Turn all microphones on. String formats: “MI1,5,B” is a valid format. Turns on microphones 1,5 and 11. “MO2,3,E” is a valid format. SM8 Microphones 1-8 are addressed with ASCII 1,2,3,4,5,6,7,8. SM8 Microphones 9-16 are addressed with ASCII 9,0,B,C,D,E,F,G. For example, to punch up microphone 14, you would send “MIE Warranty All ETS products carry a one year parts and labor warranty.
