Connect the
Power Sensor
to the iPM-1 using the cable (EMR Model #CO8801A-PP-240) to the RJ-11-6
Connector marked Directional Coupler (see Fig 18).
The LCD display should now read “0 FWD 0 REV”.
Using the computer log back on to the web page and view the home page.
Key up the transmitter and the RF power should be displayed on the LCD Display and the home page. Also, VSWR
should change from No Signal to a reading of the VSWR . Un-key the transmitter.
Note: There is latency on the home web page. Readings are delayed.
Next test the COR Sense by applying a high (5 Vdc) to the COR Sense line. The Reading should change from “Off”
to “On”.
Now tie the PTT Test line and the PTT Sense line together and click on the PTT Test Submit Button on the web
Page. PTT Sense should change from “Off” to “On”.
The final test will be an alarm test. Since in our example we are using a 50 Watt VHF transmitter we should get a
Low Power Alarm since the Low Alarm Set point is set at 75 Watts.
Click on the Power Sensor & Test PTT Setup link on the left of the web page to view the page.
Enable the alarm by clicking on “Y” radio button in the alarm section of the Power Sensor table (see Fig 19) and
clicking on the Submit Button.
