for maximum rated output power. You may have to adjust the three parameters

5.1 Equipment Required
1. 10A DC power supply at rated voltage of Base radio.
2. Personal computer with ethernet network adapter and Meteorcomm XtermW
or equivalent terminal program installed.
3. 30 dB 100W RF power attenuator.
4. Vector spectrum analyzer for power and frequency measurements.
5. Optional 8+ digit frequency counter for frequency measurements.
6. External high stability time base (e.g., rubidium) accurate to 0.01 ppm. Can be
internal to items 4 and 5.
5.2 Set up the Radio for Testing
1. Connect a cable that has a CAT5 ethernet connector on one end and an 8-pin
M12 cable connector on the other end (MCC P/N 14001627-01). Connect the
M12 connector to the radio port labeled MAINT. Connect the other end to a
computer network card. The default radio IP address is 10.10.1.254. Set the IP
address of the computer network card to a compatible fixed address such as
10.10.1.1. The computer should have Meteorcomm XtermW or a similar
terminal emulation program installed.
2. Find the input voltage rating marking on the radio chassis near the power input
terminal block. It is either 24VDC or 48VDC. Adjust a 10A DC power supply to
the proper voltage; then disable its output. Observing polarity markings
connect the power supply between the radio power terminals and the power
supply.
3. Apply power to the radio. Wait 30 seconds to open an XtermW session. Use
the Edit/Configure Port window to set Port Type = TCP/IP, Protocol = Stream,
TCP/IP Settings Host = 10.10.1.254, Port 4000. Select Device Type = MCC 6100
SDR (which also applies to ITC radios). Return Character = CR, Data Format =
ASCII.
