How do I configure Zello For Work radio gateway software?

Follow these steps to configure your gateway:

1. Make sure that your radio is connected to the PC and turned on. 

2. Login into Zello For Work using login and password assigned to your gateway. When logged in you should see a status screen like this:

TX denotes Zello For Work to radio direction and RX — radio to Zello For Work. VOX mode is used by default in both directions.

When online the gateway will appear in the contacts of the users of your network (if they are in the same channel(s) as the gateway):

 

3. Open gateway settings using Tools > Options... menu:

TX tab allows you to control your radio PTT is controlled. If your radio supports VOX and you use direct cable connection rather than an interface hardware, you can select VOX here.

Wake up sequence length allows you to set the length of a tone which is sent to your radio before the actual transmission in order to trigger its VOX circuit and avoid loss of the beginning of the message.

Most hardware interfaces use COM port to control PTT of your radio. You can select the port, where the interface is connected as well as RTS or DTR signal and low or high active level.

CM108 option is for the interface devices based on C-Media CM108 chip such as USB Radio Interface (URI). This option is disabled unless the device is present in your system. The support of CM108 isn't finished yet.

RX tab is similar and controls the way Zello For Work gets Squelch signal from the radio:

Zello For Work includes a robust VOX algorithm. In the most portable radios there is no digital output for Squelch signal so you'll have to use VOX. On the contrary many mobile radios and repeaters offer digital COS output via accessory connector so it could be used for higher quality link with appropriate hardware interface.

Like in TX configuration you can select the desired COM-port, type of control signal (CTS or DSR) and active level. If you use VOX for RX, you should configure it on VOX settings tab:

Activation threshold is a sound level of the signal from radio, above which the transmission starts.
De-activation threshold is a sound level, below which it stops. It can't be higher than activation threshold and usually it's a good idea to have ~5dB lower.
Trigger time is a typical time VOX takes to trigger transmission. Increasing it will help getting rid of false transmissions caused by short impulses
Relaxation time is a typical time VOX takes to turn off. Increase it to allow longer pauses between words in transmissions.

Please note that these settings only affect the way your gateway receives transmissions from the radio and don't affect radio's internal VOX circuit settings.

4. Click OK to close settings and apply your new configuration.
