Even when using the DR-2X/DR-2XE with an external controller, the COR, analog and digital IDs, TOT, DCS/CTCSS, TX
power, etc. are already controlled by the DR-2X/DR-2XE internal control. These internal controls cannot be disabled. The
external controller must not conflict with these functions. Some functions of the internal controller cannot be overridden.
Before connecting an external controller you must make sure which functions are already internally controlled. Special
precautions must be considered when planning to link with external systems.

Make sure to switch OFF the power to the radio before connecting the cable.

In case of jamming or interfering signal while in Repeater mode, Pin 1 may be grounded by external control to
temporarily disable repeating the receiver input.
Transmitting C4FM digital signals
For digital modulation operation, the packet speed (data transmission rate) of the repeater must be set to 9600
bps, remember to change the default setting from 1200 bps.
If the repeater is expected to transmit digital modulation signals while in base station operation, set the packet
speed to 9600 bps before starting base station operation as below.

To use DR-2X/DR-2XE in Remote mode
By setting [ REMOTE
] in the setup menu to ON and inputting a low level to Pin 1 of the [CONTROL I/O]
connector, the repeater may be used in Remote mode and controlled remotely by the external controller. Pins
1, 8, 9, 11, 12, 13 and 14 may be used for input, output and control while in Remote mode.
For details, see “Remote Operation” (see page 42).
