Via the MDF Krone interface, it is possible to connect all required signals towards a Voice Control and Command System (VCCS). In addition an antenna changeover unit is used in this configuration to control main/standby switching manually or automatic.

• TX audio line

• TX ground keying (PTT)

• TX alarm output

• TX select input (used for main/standby switching)

• RX audio line

• RX squelch output

• RX alarm output

• RX Select input (used for main/standby switching)

• Ethernet (LAN) interface

This system illustrates the use of a pair of Audio and PTT modems (APM) using the MDF Krone interface. The APM gives the system the ability to transfer PTT, squelch and alarm signals as in-band tones between the radio site and the operator site.

• TX audio line

• TX ground keying (PTT)

• TX alarm output

• TX select input (used for main/standby switching)

• RX audio line

• RX squelch output

• RX alarm output

• RX Select input (used for main/standby switching)

• RS-485 remote serial bus

The following units are available from Jotron to perform the required functionality:

• ARC – Audio Remote Control. Connects to the radio using 4W audio, PTT, squelch, alarm and select signals. Gives the user the ability to transmit and receive using the remote control, in addition the user has access to main/standby switching and alarm monitoring of the units.

Maximum range for the remote control depends on the quality of the copper wires used, but is in the range 200-300 m.

• DRC – Data Remote Control. Connects to the radio using the RS-485 remote serial bus. In addition the DRC is powered by the external voltage available on either the radio units or the ARC.

Gives the user the ability to change the operating frequency and monitor certain built in test (BIT) signals in the radios.

• ORC – Operator Remote Control. Connects to the radio using the RS-485 remote serial bus. In addition the ORC is powered by the external voltage available on either the radio units or the ARC.

Gives the user the ability to change the operating frequency between pre-stored frequencies in the radio.

• APM – Audio PTT Modem. Allows the use of in-band signalling to transfer squelch, PTT and alarm signals between the operator and the radio site. In addition, the remote APM unit contains an antenna switchover relay to switch the antenna between the main and the standby radio units.
