Disable Active State
You can choose whether a receiver is disabled by means of a high or low voltage state input to J3.
This selection can be made for each channel; that is, you can set each channel to either high or
low separately. Press the
Menu
button until the "Dis Active State" menu is displayed. Press the
Selection
button until the desired channel is displayed, then press the
Data
button to select high
(HI) or low (LO).
Active HI means your controller or other external device must produce a positive-going voltage
(6.5 to 20 volts) when the channel is to be disabled, and a low-going voltage (0.0 to 4.5 volts)
when the channel is to be enabled. Active LO means that your controller or other external device
must provide a low-going voltage (0.0 to 4.5 volts) when the channel is to be disabled, and a high
going voltage (6.5 to 20 volts) when the channel is to be enabled.
COR Active State
You can choose whether a high or low voltage state indicates an active COR input on J4. This
selection can be made for each channel; that is, you can set each to channel to either high or low
separately. Press the
Menu
button until the "COR Active State" menu is displayed. Press the
Selection
button until the desired channel is displayed, then press the
Data
button to select high
(HI) or low (LO).
Active HI means that your receiver COR must produce a positive-going voltage (6.5 to 20 volts)
when the squelch is open (receiving a signal) and a low-going voltage (0.0 to 4.5 volts) when the
squelch is closed (no signal). Active LO means that your receiver COR must provide a low-going
voltage (0.0 to 4.5 volts) when the squelch is open and a high-going voltage (6.5 to 20 volts)
when the squelch is closed.
