Working with Base Stations from Your PC
TB9400/TN9275 Installation and Operation
© Tait International Limited May 2023
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 page
(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 WebUI 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 is to reject transmissions from
radios that do not belong on the network.
Use of 250.3Hz and 254.1Hz CTCSS tones
The receiver has a known issue where reverse tone burst signaling on
CTCSS tones of 250.3Hz and 254.1Hz can briefly trigger the other
detector. D
o not use both tones in the same network. I
f using either tone,
be aware that there is a risk of falsing if co-channel transmissions are using
the other tone.

Checking for Interference on a Receive Channel
You can use the Signal Level page (Diagnose > RF Interface > Signal
Level) to look for sources of interference across a range of receive
frequencies.
