Frequency Decoding, Ctcss Level | Telex IP-223 manual

Installation and Level Settings

To adjust the TX monitor, do the following:

1.In the options section of the Per Line Setup window, select the TX Monitor.

NOTE: If this feature is not necessary, or the line is in 2-wire mode, the TX Monitor field in the Options section on the Per Line Setup window should be cleared.

2.Verify the RX alignment is completed first.

To perform a standard alignment for a 4-wire system, do the following:

1.Transmit a 0dBm test tone on the TX audio pairs pins 13 and 25.

2.Measure the RX level on test point TP13 for line 1 or TP1 for line 2.

3.Adjust potentiometer R390 for line 1 or potentiometer R391 for line 2 until 0dBm is measured between the test point and GND. (0dBM = 2VPP = .707VRMS).

NOTE: Do not adjust the RX potentiometers.

4.Use the RX alignment tool (VU meter) accessed through the LCD display (press and hold the line button and then momentarily press the IC button 3 times) to verify the dBm level.

CTCSS Level

The CTCSS level is measured by connecting an oscilloscope or RMS meter to ground and Radio 1 CTCSS test point (TP7) or Radio 2 CTCSS test point (TP10). With the radio connected to the CTCSS output, have the remote console open to receive audio so CTCSS is present. Adjust the Radio 1 CTCSS potentiometer (R50) or Radio 2 CTCSS potentiometer (R53) until the desired level is achieved.

Frequency Decoding

The IP-223 is factory tuned to the frequencies shown below. The detection frequencies cannot be changed as they are coded into the software. However, any actual function or output can be made to work with any existing programmed frequency. Please consult the factory for special requirements for frequency selections.
