IR LEARNER - CONNECTIONS & FEATURES
The HTR-2400 features an internal
eight source IR Learner that is based
on ADA’s IRL-5000. The latter sec-
tion of this manual discusses the pro-
gramming of the IRL. The diagram
to the right shows the out of the box
setup of the HTR-2400. Ports can be
reassigned during the HTR-2400
setup to suit your custom installation.
The IRL can be removed to alter IR port operation or to even program the IRL in the shop
while the HTR-2400 chassis begins to be installed. To do this, simply connect a 12VDC
500mA power supply to the IRL board to program the IRL outside of the HTR-2400 chassis.
There are three types of jumper pin settings; IR Flasher, IR Repeating, and Serial Data Con-
trol. The IR Flasher jumper pins are a group of eight jumper pins together. The out of the
box setup has these jumper pins offset (un-shunted) so the pins are there but simply not in
place. When these pins are offset (not in place, un-shunted), the port they reference are set
to use an IR flasher (emitter). When the jumper pin is in place (shunted), the port is set for
serial data control with the IR carrier stripped out.
The other two types of jumper pins are grouped by port number. The IR Repeating jumper
pin determines if the port will pass IR that comes down the ADA Bus from IR receivers located
in keypads (or the IRR-5000). To defeat IR repeating entirely for a port, remove or offset the
jumper pin. If you require IR repeating, set the jumper pin to the appropriate position (IR
flasher or serial connection {no IR carrier}). If the IRL is working from the PC program’s
Simulator but not from the keypads, and the keypads have been programmed to track
the appropriate IRL ports, then turn IR repeating OFF by offsetting (removing) the IR
repeating jumpers.
REASON - When a keypad issues a transport command, the RS-232 code for the IRL
is sent down the ADA Bus to the IRL so that it can then issue the source’s IR command. If repeating is on, the
keypad’s command first emits through the IR flasher. If the source component’s IR receiver is slow to cool down
(so that it can take the next IR command), when the IRL releases the actual command (a moment later), the
source component’s IR receiver may reject it. By turning off IR repeating, only the IRL source function is sent.
The last jumper pin is the Serial Data Control jumper pin which is only used if you are
connecting to a source component’s rear panel serial data connection. Here you can opt to
send the serial data in the nor-
mal (Norm) position or inverted
(Invert) position.
There is also an IR Repeater
Frequency trim pot that ad-
justs the IR carrier frequency for
IR repeating only. This pot has
no effect with keypad control.
