Graphical interface

The remote control transmits audio signals, switches channels and polls the current channel of the radio station by sending commands to the RRC-01 executive device online. At the same time, the radio station can be in any programmed mode (conventional, trunking, conventional in roaming mode, and others).
Functions of the right and left buttons
In order to facilitate the operational control of the device, the main control icons displayed on the screen are duplicated by mechanical buttons located to the right and left of the display, opposite the corresponding icon on the display screen, depending on the operating mode:

When you press the left button, a new window appears, which displays the current channel number (or call sign) of the selected radio station and control icons:
“channel UP”, “channel VZAD”, “BACK”;
channels are pre-programmed in radio stations;
The programming mode of radio stations with the PDU-04 remote control is not supported.

Modes of operation

The mode of receiving voice messages is always carried out from all connected peripheral devices at the same time. When receiving voice messages from several connected devices, the voice signals are mixed and sent to the remote control speaker. At the same time, a green icon flashes on the touch screen of the remote control, opposite the windows with active devices, which means “receiving” a voice message from this device. The operator sees some radio stations on the air and can select the “necessary” peripheral radio station to answer the subscriber by pressing the corresponding button on the right side of the display.

To send a voice message, select one or more radio stations (for group calls) using the buttons on the left side of the display. The call is made by pressing the push-to-talk button on the front panel of the remote control.
Executive device RRC-01
The RRC-01 executive unit connects to the radio with an interface cable for voice/data and power.

Connection between devices

To control more than 4 radio stations, the remotes are connected by interface cables to a common control unit.
“Interblock connector” – for connecting the device to a source of direct current, with a power supply voltage of 13.8V and combining several remotes using the appropriate cables.
The power cable is connected to any connector “Interblock connector” of any PU.
The remote controls are connected to each other using the same free connectors of the cables of inter-block connections (hereinafter – the inter-block cable). To simultaneously switch all radio stations to the “TX” mode during the transmission of emergency or circular messages, the PTT button or pedal is connected to the free connector “Inter-unit connector” of any PU.
