System Learning Remotes
These remotes are designed to control the functions of a stack of same-brand equipment, as well as learn the
IR commands of other equipment. Often the PLAY buttons on these remotes send two IR commands: one
to the receiver to select the input, and one to the player (CD, Tape, etc.) to start it playing. When using this
type of remote to program IR commands into the PX-600, the PLAY command often gets cut off and is not
stored properly. When this happens it will appear that the PX-600 cannot control the source equipment.
For this reason, it is best to use the transmitter for the player itself whenever possible.
However, sometimes the individual player's remote is not available or doesn't exist. To program the PLAY
command or any other command using a System Remote, follow this procedure:
1.
Place the remote in the proper location for programming.
2.
Place your hand between the remote and the PX-600 Programmer.
3.
Press PLAY - your hand will block the first command (SOURCE SELECTION).
4.
Move your hand in time to record the second command (PLAY). This may take only a fraction of a
second.
It may take a little practice to get the timing right, but it works and it may get you out of a jam.
IR Programming tips for Tape Players
There are different formats for the control of tape players, and clients have differing needs or expectations
of how a player should respond from a keypad or remote. With this in mind, we have outlined the
programming protocol for the TAPE input along with some suggested ways of using it.
During IR programming for TAPE, enter the number of tapes the player has and the commands for: PLAY,
STOP, REVERSE PLAY and FORWARD PLAY, then TAPE 1A/1B, TAPE 2A/2B, etc. The PX-600
issues PLAY the first time TAPE is selected in a zone, unless it was already selected in another zone.
STOP is issued shortly after the first zone is turned on in the system, after the last zone is turned off and
whenever the user switches out of TAPE, unless another zone has TAPE selected.
The REVERSE PLAY and FORWARD PLAY commands toggle back and forth each time you press TAPE
after the first time. Normally these provide a CHANGE DIRECTION function on players that have two
PLAY buttons.
TAPE 1A/1B, 2A/2B, etc. are two-step commands issued when you press and hold the TAPE button. The
intended use of the two steps is to accommodate multi-tape changers that require a tape select command
followed by the tape number or the tape number followed by PLAY. Most players change tapes by pressing
the tape number only, in which case enter the tape number in the “A” step and skip the “B” step.
If you have a tape player with one PLAY button and a DIRECTION button:
1.
Enter DIRECTION for both the REVERSE PLAY and FORWARD PLAY commands so that you
get the DIRECTION function each time you press TAPE after the first time. Using this option, you
could tell the PX-600 you have 2 tapes and enter FF into TAPE 1A, press STORE to skip TAPE 1B,
then enter PLAY into TAPE 2A and press STORE to skip TAPE 2B. You'll now be able to toggle
between FF and PLAY on the press-and-hold function.
2.
Enter FF into REVERSE PLAY and PLAY into FORWARD PLAY, then enter DIRECTION in
TAPE 1A. This toggles between FF and PLAY to find a particular part of a tape. When you press
and hold TAPE, you change the direction of play. Another twist to this is to tell the PX-600 that the
player has 2 tapes as in Option 1, and enter REW and PLAY in TAPE 1A and TAPE 2A. Then you
toggle between FF and PLAY by momentarily pressing TAPE and toggle between REW and PLAY
using the TAPE press-and-hold function.
