86 Part E: Configuring the Base Station
© Tait Electronics Limited December 2007
To map digital inputs to bits used for channel selection
1. Select Configure > Base Station > System Interface.
2. Enable and configure external channel selection (see “Configuring External
Channel Selection” on page 85 ).
3. Click Map Inputs . The Map Digital Inputs dialog box appears and displays
a table showing the default mapping of digital input lines to the bits used for
channel selection.
4. Edit the numbers in the Digital In column as needed, so that they do not
select digital lines that are in use as digital outputs.
5. Click OK . The pinout table has updated to show the new mapping of digital
inputs to bit numbers.
Configuring RSSI Output
If your system has equipment external to the base station that needs an RSSI
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.
Tip:
Alternatively, leave the RSSI output as it is and adjust the
external equipment to work with that output. Use the RSSI output
test when making the adjustment (Diagnose > Reciter > Misc I/O).
