REMOTE CONTROL
Translator: When the adjacent switch is depressed, the ‘hi’, ‘lo’, & ‘gnd’ terminals on the SPM412e rear panel Remote connector provide
a ‘Translator’ input, which allows third-party controllers (such as AMX
®
, CRESTRON
®
, and RANGER
TM
) to directly interface to, and control,
the SPM412e. To interface a third-party controller to the Translator input, connect the controller output to either the ‘hi’ or ‘lo’ terminal on
the SPM412e (depending upon high or low idle signal from the controller) and the controller ground to the SPM412e ‘gnd’ terminal. For
reliable operation it is recommended that the SPM412e be located within 10 feet of the third-party controller. The Translator input is
compatible with bi-polar signal voltages (such as -12V to +12V RS-232 signal levels) as well as uni-polar signal voltages (such as 0V to
+5V TTL or CMOS logic signals). The maximum input voltage range for the Translator input is -15 Volts DC to +15 Volts DC, The
switching threshold for the Translator input is approximately +2 Volts DC (at idle-high terminal) or +3 Volts DC (at idle-low terminal). Input
impedance for the Translator signal is about 6k ohms. The third-party controller must be programmed to output a ‘carrier-stripped’ bit-
stream in the Biamp format (contact the controller manufacturer to determine if their device driver library supports the Biamp format).
