Modulation/Baud Rate

The options listed in the “Modulation / Baud Rate” dropdown menu are: 
2 Level/4800, 2 Level/9600, 4 Level/9600 and 4 Level/19200. The value assigned 
to this parameter must be identical to the corresponding parameter in the Psion 
Teklogix Base Station. This parameter is stored in the radio’s non-volatile memory. 
The default value for “Modulation/Baud Rate” is 2 Level/9600

Data Squelch

“Data Squelch” controls the radio receiver, cutting it off when the signal is too weak 
for reception of anything but noise. Receive Signal Strength Indicator values below 
the “Data Squelch” threshold prevent further processing of the receive signal while 
higher values allow further processing. The allowable range is 0 to 100 with a 
default value of 0.
In noisy environments, this value can be increased to reject noise. In environments 
with less noise, this value can be decreased to allow the received signal and increase 
range. This parameter is stored in the radio’s non-volatile memory.

Test Squelch

•

Tap on the Test Squelch button to prompt the radio to use the “Data 
Squelch” value without committing it to the radio’s non-volatile memory – 
in other words, to ‘test’ the value assigned to the “Data Squelch” parameter. 

To commit the new “Data Squelch” value to the radio’s non-volatile memory:

•

Tap on the OK button – the dialog box is closed and the new value is saved.
