19. Remote Operation with External Controller
Repeater operation may be controlled remotely by connecting an external controller through the [ CONTROL
I/O ] connector at the back of the repeater.
The following features are available while in remote operation:
•
Change the communication mode of repeater transmit and receive
•
Turn the RX and TX tone signal "ON" or "OFF"
•
Monitor the discriminator analog or demodulated digital audio during up-link reception
To use the repeater under remote control, set up the repeater as explained below, after it is connected to the
external controller.
Turning remote operation ON/OFF
When the remote operation is "ON", the repeater operates according to the control instructions received from
the external controller (the instructions are received through Pin 11 to Pin 14 of the [ CONTROL I/O ] connector).
When the remote operation is "OFF", the repeater operates according to the settings determined through the
setup mode.

Control from external controller
To control the DR-2X/DR-2XE remotely, optional cables can be used
to connect the repeater to an external controller.
Use the "CONTROL I/O" connector at the back of the repeater to con-
nect with the external controller.
To interface the DR-2X/DR-2XE with an external controller, additional
cables with a 15-pin mini d-sub connector are needed to connect to
the "CONTROL I/O" connector. Your controller may also require rewir-
ing.
Link operation may require four connections: receiver audio, transmit-
ter audio, receiver COR, and transmitter PTT; however, these are not
available on the "CONTROL I/O" connector.
The pin assignment of the "CONTROL I/O" connector is as follows.
Do not use a VGA cable for PC display to connect the external controller
to the repeater.
