IVIS option technical appendix

Preliminary version

ParagonPD+ Deviation adjust for optional Integra VIS controller/switch (IVIS)

The ParagonPD+ optional Integra VIS (IVIS) deviation must be adjusted to match its associated

base station.

Referring to Section 4.1, obtain and setup “Required Equipment” listed. Following initial

matching, deviation testing is an annual check.

The setup port of the IVIS controller module is used to connect the PC running the system

software supplied along with the module. The procedure outlined below may ONLY be carried

out to calibrate the IVIS module. If the Exciter needs re-tuning or for annual maintenance check

or troubleshooting, the procedures outlined in Section 4 MUST be followed.

1. From the operating network settings, record the speed (19.2 or 9.6 kb/s) and the channel type

(25 or 12.5 kHz). Using the software’s “Production Test window”, select “Tx Deviation Adj”

radio button in “Adjustments frame” and set “Tx Mode” to Tone.

2. Press F5 (Tx On Tx frequency) to start the transmission.

3. Using PageUp/Dn or Ctrl+PageUp/Dn., adjust the “Tx Deviation Adj” value until the

deviation reading on IFR matches or is slightly less than the value in the “Tone” column of

the table below. Record the reading of the “Direct Adjust” field from the “Adjustments”

frame (initial value)

Speed and Channel Tx Mode

“Tone”

Tx Mode

“Random Data”

19200b/s 25kHz ±4.0 kHz ±4.5 kHz

9600b/s 25kHz ±4.0 kHz ±4.8 kHz

9600b/s 12.5 kHz ±2.5 kHz ±3.0 kHz

4. Press F5 to toggle the transmission OFF.

5. Change the “Tx mode” to Random Data.

6. Press F5 to toggle transmission of “Random data” ON. Measure the deviation and check that

it is equal to or less than the value in the table. Press F5 to toggle the transmission OFF.

7. If the measurement at step 6 is excessive, repeat steps 2-6 once to obtain deviation readings

that best correspond to the table values. If unable to obtain a “Direct Adjust” reading (after

editing up and/or down) that varies from the initial value (from step 3 above) by less than 2,

contact System Engineering.

8. When satisfied with value obtained, press “Write” button on the button bar to write the value

in the unit’s flash memory.
