13. RELAY CTRL Jack: This RJ45 jack is used to control the StationPro’s
remote RF relays. The jack accepts a standard 8-wire ethernet-type patch cable (with
RJ45 connectors). The cable should be no longer than necessary (5 – 6 ft or shorter), and
preferably shielded. The free end of the cable plugs into a mating connector on the RF
relay unit. Builders of custom RF relay units should refer to the StationPro schematic
diagram for the connector pinout,
14. PACKET/RTTY Jack: This standard 5 pin DIN jack is used to connect
RTTY, Packet, and PSK31 peripherals to the StationPro. The pinout is shown in the
diagram. Note that all of the pins on this jack are in parallel with similarly named pins on
other jacks on the StationPro. The AUX4 pin is not designated for any specific purpose,
but may be configured by the user for an additional function (e.g., squelch, etc.)
15. +12 IN Jack: This DC power jack accepts a standard 2.5 mm DC power plug
(center pin positive), which should be connected to a +12V (nominal) regulated DC
power supply. This power supply can be a s12V supply used to power other
equipment (e.g., a VHF/UHF FM transceiver), the acc12V port on the rear panel
of most transceivers, or even a dedicated wall-wart supply. The power supply should be
rated at 500 mA or greater and have good filtering..
