Van Alstine rev 2 ABX Switch Manual - page 3
The ABX switch uses a universal remote set to “Sony” codes. An RCA RCU-403R or RCU-404R remote
comes pre-programmed with each ABX Switch. This remote is readily available on-line and at stores
should it become lost or damaged. A new remote must be programmed for Sony codes. Both the “TV” and
the “VCR” portion of the remote must be set, and the remote must function as if controlling a VRC.
Program the RCA model RCU-403 / RCU-403R to work with the ABX Switch by doing the following:
1) press and hold “code search” until remote’s LED lights. Release “code search”
2) press and release “tv”. LED will blink
3) press and release the four digits “0001”. The LED will flash after each digit and then go out..
4) press and hold “code search” until remote’s LED lights. Release “code search”
5) press and release “vcr-dvd”. LED will blink
6) press and release the four digits “0032”. The LED will flash after each digit and then go out.
7) Ensure remote is in vcr mode by pressing “vcr-dvd”. If remote is in “TV” mode, play, stop, and
record won’t work. If TV portion is not programmed, volume changes won’t work.
The infrared receiver used with the remote is located in the ABX switch between the display and the A
source LED. There needs to be a clear line of sight from the remote control unit to this infrared receiver.
“REC” button: This remote requires the “REC” button to be pressed twice before the “REC” code is
transmitted. A bit of added security to prevent unintended changes to the desired power up state.
Low Batteries: When any button on the remote is pressed and held, the remote should transmit the code for
that button as fast as possible. The red LED in the upper left corner of the remote should reflect this by
being on continuously while the button is depressed. If a button is pressed continuously and only one flash
of the red LED in the upper left corner of the remote occurs (and only one code is transmitted to the ABX
Switch) the remote’s batteries are low and should be replaced.
On-Off: Used as a qualifier for multi function buttons. Some buttons do more than one thing. For
example: “1” will select A source, “On-Off” followed by “1” will enter blind test mode.
