Programming

From the ZR310 Configuration Screen, you may set the programmable features. Programmable feature in the ZR310 are divided into three categories:

System Programmable Fields

User Programmable Fields

Diagnostic Tests

System Programmable Fields

The following subparagraphs describe the system commands available for the ZR310.

Program Mode Access Code

The program mode access code is a number between 1000 and 32000.

Morse ID interval, Speed, and Frequency

You can program the Morse Code station identification in frequency, interval and speed. The following table outlines the programmable range and the default settings of each.

Frequency

Interval

Speed

Programmable Range

Default

400-2000Hz

1200Hz

1-99

15 Min

4-25 wpm

22 wpm

Each user on the ZR310 has its own independent station ID timer that is accurate to one second per interval. When the station ID is sent, the timer is reset. The call is transmitted on the first dispatch message after the timer has expired.

During normal dispatch, the minimum character speed will be 15 wpm. This allows the "List" functions (using Morse code as a format) to be sent at very slow speed, while maximizing airtime use during normal dispatch.

Courtesy Tone Frequency

The courtesy tone is used for courtesy tone and prompt beeps. It is programmable in frequency from 400 to 2500 Hz, and the default setting is 1000 Hz.

A possible reason to change the frequency could be to differentiate between co-channel repeaters to know which repeater site is active.

System ID User Number

A user number may be assigned as the "System ID user number" so that the repeater will identify every ID interval (1 to 99 minutes).

Before sending the System ID, the following conditions must be met:

The system ID interval timer must expire (adjustable 1 to 99 minutes).

The ZR310 must be inactive (TPL/DPL Decode LED off).

The System ID must have a number programmed.
