76 Part E: Configuring the Base Station
To configure external channel selection
1. Select Configure > Base Station > System Interface.
2. Select the Channel selection check box. This enables external channel
selection.
3. In the Pins to use box, select an option. For each bit in the binary channel
number, you need a pin.
The table to the left updates to indicate which pins are for channel selection
and the Number of selectable channels box updates to indicate the high-
est channel number that the hardware will be able to select.
4. Specify whether the external equipment selects the channel number using
binary or BCD format.
Important: The base station interprets a line as '1' when it is active
(when the external equipment is pulling it to ground, the voltage is
low, and current is flowing).
5. If the external equipment pulls a line to ground to indicate a '0', select the
Invert box.
6. Use the Service Kit to test your setup. See
Selection" on page 157.
Note: Setting the channel to 000 (by switching all DIP switches
off—or on, if the selection is inverted) disables external channel
selection. The base station will operate on the channel selected by
the Service Kit or by
If your system has equipment external to the base station that needs an
voltage, you can configure that voltage to suit the equipment.
If the equipment is configured to operate with older Tait base stations, you can
specify that the RSSI output behaves like the output from a Tait T800 VHF or
UHF base station.
For other equipment, specify the maximum and a minimum output voltage that
your equipment expects, and the maximum and minimum signal strengths that
the base station needs to deal with. The base station will then map the signal
strength range to the output voltage range. When it receives a valid signal, it
outputs an RSSI voltage based on the strength of that signal.
Alternatively, leave the RSSI output as it is and adjust the
