Retry Period

This parameter is found in the System Configuration Menu. It holds the time interval, in

seconds, for which the Model 26 waits for a reply after polling a Model 6. The Model 26

will do 4 retries before posting a communications error for the Model 6. This parameter

should be as short as possible to minimize system delays whenever retries occur.

However, it still must be long enough so that the Model 6 has time to respond. Keyup

delay time at the Model 6 needs to be added to this number as does Model 6 Trunking

Grant time. This parameter will accept a value between 0 and 59.99 seconds.

Realistically, 0.20 seconds is a minimum value for this parameter and anything greater

than a second will severely degrade system performance during any kind of

communication problem.

Max Timeout

This parameter is found in the System Configuration Menu. It holds the maximum time

the Model 26 waits for a clear channel before transmitting if the channel is busy. If the

value of this parameter is 0 (the default), then the Model 26 never transmits unless the

channel is clear. This parameter accepts a value between 0 and 59.99 seconds.

Voice Debounce

This parameter is found in the System Configuration Menu. The value of this parameter

is the period of time for which the Model 26 will not transmit on the channel after it stops

receiving non-FFSK data. It is used to prevent the pauses in normal speech (VOX

communication mode) from giving a false channel clear indication. The value can range

between 0 and 59.99 seconds, but it is typically set for about 1.50 seconds.

FFSK Mute Debounce

This parameter is found in the System Configuration Menu. This parameter is the period

of time, after the Model 26 sends or receives FFSK data that it continues to assert the

DATA MUTE signal. This is particularly important after a transmission for which the

Model 26 expects a response. If the DATA MUTE signal is not being used to mute a

console this parameter has no real importance. The value of this parameter can range

from 0 and 59.99 seconds. Typically, a good starting value is about 0.15 seconds plus the

longest Model 6 keyup time.

Data Mute Active Polarity

This parameter is found in the System Configuration Menu. It is used to set the active

polarity of the Data Mute (J13-7) output signal. When this parameter is set to “Low,” the

Data Mute signal goes low during a mute condition; otherwise, it is high. Selecting this

parameter toggles it between “Low” and “High” settings.
