batteries are correctly oriented and properly seated in the battery holder.
The B100 remote is a full function remote. It allows selection of all sources, volume up or down (the volume
control is a motor-driven design), mute ,left/right balance, power on/off and discrete code entry.
We recommend maintaining a direct line-of-sight between the hand held remote unit and the front of the B100 to
ensure the most efficient operation of the remote features.
PROGRAMMING the HANDHELD REMOTE CONTROL:
The automatic motion-sensing backlight function in the handheld infra-red remote control unit can be disabled by
entering the 3 digit code “792” as follows:
1) Press and hold the CODE button for 5 seconds. Release when the LED flashes red.
2) After the LED stops flashing, enter the 3 digit code “792” by pressing the buttons D1, D3 then AUX/PH (see illustra-
tion on page 3)
3) To re-enable the motion-sensing backlight function, repeat steps 1 and 2 above
To completely disable the backlight, enter the 3 digit code “797” as follows:
1) Press and hold the CODE button for 5 seconds. Release when the LED flashes red.
2) After the LED stops flashing, enter the 3 digit code “797” by pressing the buttons D1, D3 then D1 (see illustration
on page 3)
3) To re-enable the backlight repeat steps 1 and 2 above
SENDING CODES to the B100 via the IR HANDHELD REMOTE CONTROL:
Press the CODE button on the remote control (the red LED will light) and then enter the 3 digt code, as listed in the
“Wired RS232 Remote Control” section” below . The LED will flash to confirm transmission and then extinguish.
WIRED RS232 REMOTE CONTROL:
Using the DB9-female connector at the rear of the unit, the B100 can receive commands via a null modem cable at
9600 baud, 8 data bits, no parity and 1 stop bit (9600,8,N,1). Valid commands will return the “>” character indicating
that the unit is ready to receive a new command. An invalid command will return the “!” character. These serial data
commands are as follows:
000 - power off 015 - power on/off toggle 081 - select digital source 1 (D1)
001 - select analog source 1 (A/D) 019 - balance left 082 - select digital source 2 (D2)
002 - select analog source 2 (AUX/PH) 020 - balance right 083 - select digital source 3 (D3)
003 - select analog source 3 (CD) 029 - power on 084 - select digital source 4 (D4)
004 - select analog source 4 (TUNER) 058 - mute on 245 - set/reset Pass Through mode
005 - select analog source 5 (TV) 059 - mute off 247 - Set Trigger 2 for current source
006 - select analog source 6 (VIDEO) 061 - record monitor toggle 248 - Clear Trigger 2 for current source
007 - volume up 062 - record monitor on 255 - System reset; restore defaults
008 - volume down 063 - record monitor off
PASS THROUGH MODE:
PASS THROUGH mode sets the pre-amp gain to 1 (unity gain) and locks out the volume & balance controls for any
single analog audio source. For example, if the Front Left and Front Right outputs of a home theater surround sound
processer were connected to the TV input of the B100, and then PASS THROUGH was engaged then whevever TV
input is selected the volume and balance controls would be locked at unity gain. If other inputs were subsequently
selected, volume and balance controls return to normal operation for those other input sources. Only the TV inputs
would be locked at unity gain. PASS THROUGH mode, therefore, can only be assigned to one input at a time, but
that input can be any one of the analog audio inputs. The power amplifier stage is not affected by PASS THROUGH
mode. PASS THROUGH mode can only be set (or reset) by sending the 3 digit code “245” to the B100 either from the
handheld IR remote control or via the RS232 serial data input. See “Sending Codes to the B100 via the IR Handheld
