CHAPTER 6: BASE STATION MODE
Overview
In addition to its repeater features, the BCR repeater can be operated as a base station. While in base station
mode, the system operator is able to communicate with any user on the selected channel.
Operation
To switch from repeater mode to base station mode, simply press and release the BASE button on the front
panel. The BASE LED will illuminate. The BASE LED will stay lit during base station operating mode. The first
time that base station mode is entered, the unit will default to the user in Slot 1. Any subsequent time that
base station mode is entered, the user that was active the last time that the BCR repeater was in base station
mode will be selected. The front or external speaker can be turned on and the received audio volume
adjusted.
THE RX, VALID, AND TX LEDs ARE DISABLED IN BASE MODE.
However, the LCD display will
illuminate the current status of a call. If the unit is receiving, ‘RX’ will be displayed next to the user name. If
the unit is performing a valid decode, ‘RX VALID’ will be displayed next to the user name. When the
microphone is keyed, ‘TX!’ is displayed next to the user name. When the base station operator initiates a
transmission, it will be on the selected users transmit squelch option. Different users on the channel may be
selected by rotating the SELECT knob. During Base Station mode, it is permissible to transmit using a
deactivated user’s tone/code. In order to exit base station mode, simply press the RPTR or AUX button.
Base Station Settings
Remote mode cannot be entered during Base station mode. All selected user receive and transmit options
(courtesy tone, hang time, and Tone-in-Tail) are inherited when transmitting to that user.
CHAPTER 7: AUXILIARY MODE
Overview
By entering auxiliary (AUX) mode, the repeater's internal controller is disabled and the BCR-40U/50V may be
controlled by an external peripheral. In addition, while in AUX mode enable/disable the speaker settings.
External Controllers
When in AUX mode the BCR REPEATER’s internal tone panel is disabled and total control of the repeater is
surrendered to an external peripheral such as an LTR controller or another tone panel. Please refer to
Appendix A: for the pin-out description of the BCR REPEATER to help you make your custom cable.
When
AUX mode is entered, the circuit path is set up to where the DATA or Composite output of the
external controller has DC access to the transmitter. The BCR REPEATER requires the DC input of
the DATA or Composite output be centered at 1.5 V DC otherwise the external peripheral could
cause a DC shift to make the BCR REPEATER transmit off frequency. To help achieve the 1.5 V DC
input requirement, the BCR REPEATER incorporates a DC level shifting Trim Pot (P1) on the
internal accessory board. Open the unit to access the accessory board. This is the board the
accessory connector is on. With your external controller connected, use a DC voltmeter to
measure the DC input voltage on TP1. While the controller is sending data, Adjust P1 until 1.5
Volts DC is achieved.
