7) IR Band Mode:
The new generation of INFRACOM receivers is now switchable between Band II (55kHz -
1335kHz) and Band IV (1935kHz - 3175kHz). The standardization body (DIN / IEC) has
approved Band IV for analog and digital conference technology. This was necessary as
dimmable fluorescent lights produce harmonics which can cause a disturbance to
conference technology when transmitting with infrared light on Band II. By using Band IV this
will effectively eliminated. The IRX receiver is especially developed and optimized for use in
Band IV mode.
8) Default:
This button will set the following parameters to the factory default values:
Max Channel: 11 or 31
Startup Channel: 1
Startup Volume: 2
Muting: ON
9) COM:
Here you select the serial COM interface for the programming device. All available COM
ports of computer between COM1 and COM9 are listed. Therefore, even any available
modem or Bluetooth interfaces are listed, but cannot be used for the programming device .
Please refer to the manual for your computer or check the Windows device manager in case
you don’t know the number of the physical serial COM port.
10) Open:
A click on this button opens the communication port of your computer. This will start the
actual programming.
The control LED on the programming device should now light up or flash periodically. At the
same time all IRX receivers in the TK50 charging tray should turn on and the LCD backlight
lights up.
The parameter settings are now being programmed cyclic into the IRX receivers. The
currently programmed parameter is being displayed at the IRX receiver. Since the
programming is done very quickly, on the IRX display also changes very quickly. In cause an
IRX receiver does not automatically turn on, you can do this by pressing any key on the
receiver to wake it up. The IRX receiver must remain inside the TK50 charging tray.
When all IRX receiver displays light up and show constantly changing LCD display you may
finish the programming by clicking the Close button.
The IRX receivers will now turn off.
After programming with the programming device this must be removed from the charging
tray and the power supply must be connected directly to ensure proper charging of the IRX
receivers.
You may now connect the LKC50 programming device to another TK50 charging tray to
program another set of 50 IRX receivers.
11) Exit:
The Exit button closes the IRX tray setup program. On next program start the default settings
from item 8) will be used.
