VII. Operating Instructions and Hints
1. Power Up: Once the interconnecting cables are installed and a +12V DC power
source (500mA minimum) is plugged into the +12 IN jack on the rear of the StationPro II
control unit, the StationPro II can be turned on with the front panel PWR switch. The red
LED power indicator will light, and “SP” will be sent in morse code while the LCD
initializes. After about a second, the display will briefly show the firmware revision date,
followed by the previously selected transceiver.
On its initial power up the StationPro II defaults to TX/RX1. On subsequent power-ups
the StationPro II reverts to the previously selected transceiver. The bottom line of the
display shows the selected transceiver, with a confirming 3-tone beep and the sound of
relays clicking. The top line of the display will show “
∗
∗
No Amp

” to confirm that no
amplifier has yet been selected. (As a safety precaution, the StationPro II never selects an
amplifier at power up.)
If the user has fabricated an optional solid state relay master power controller (see
III.
Rear Panel Connectors
, Item 9: +12V Control Jack for details), then all the 120 VAC
station equipment will also be powered up at this time. At this point the transceiver
shown in the display will be “on-line” and ready to operate.
2. Transceiver and Amplifier Selection: Station transceivers and amplifiers are
selected by depressing the appropriate front panel momentary action toggle switches. A
green LED indicator will illuminate above each activated switch and the LCD will show
the selections, as illustrated in the below figure for a vintage Collins transceiver and
amplifier.
