7.1 REMOTE [ENT]
The RPM4 remote ENTER function operates by detecting the open or closed status of the REMOTE
ENTER switch.
The normal status of the ENTER switch is OPEN. When RPM4 detects a CLOSED condition held for 300 ms,
it is interpreted as equivalent to a press of the [ENT] key.
Any switch may be used to accomplish the remote ENTER function. The switch should be installed on
the optional remote ENTER cable (DHI P/N 103128). Install the switch by connecting its two terminals to
the black and white wires of the remote ENTER cable.
