Working with Base Stations from Your PC

Tait recommends that you download these configurations and store
them on your PC as a backup before altering and saving any of your own
configuration settings.
You can also generate a report containing all the base station’s
configuration settings relevant to the current application firmware (Tools >
Files > Configuration > Configuration report), which can be saved as a text
file. We recommend that you do this when the base station is
commissioned. This report can be useful later if there is a problem with the
base station. Comparing the original report with the later one may highlight
changes in configuration that are causing a problem.

Setting Up Custom Alarms
Each of the base station’s 12 digital inputs can be used to raise a custom
alarm when the input goes high or low. The Custom Alarms form
(Configure > Alarms > Custom Alarms) allows you to assign a name to
each custom alarm.
The active state of the inputs (active high vs. active low) is configured on
(Configure > Base Station > Programmable I/O)
Custom alarms are reported via the web interface and SNMP traps.
Custom alarms provide a warning when an external event activates a digital
input. You can rename any of the available alarms to provide a more
meaningful name, such as “Door open”.

Subaudible Signaling
The purpose of CTCSS and DCS signaling (PL and DPL) is to reject
transmissions from radios that do not belong on the network. If possible,
you should avoid the following subaudible codes, which can be subject to
false triggering from P25 or DMR signals:
Subaudible Type
Code Values
CTCSS (PL)
131.8 Hz
199.5 Hz
233.6 Hz
DCS (DPL)
356
431
723
