F/1000V bypass capacitors should be 240 VAC line-rated)
10. +24V RLY IN Jack: This 2.5mm DC power jack may be used to connect an
external DC power supply (+15V to +30V) to user-supplied external RF relays. This jack
is not used with the standard RF Relay unit. Some users, however, may prefer to build
their own RF relay units using, e.g., surplus vacuum relays, which typically operate at 24-
28V. In this case, the StationPro will automatically connect the relays to this external
power source.
11 REM IN & REM OUT Jacks: These RJ-25 jacks are used only when multiple
StationPro IIs (up to a maximum of three) are networked together. Download the
“StationPro II Networking Manual” for additional information. Users who have only one
StationPro II can ignore these jacks.
12. CAT Jack: This female D-SUB 9 pin (DB9) connector is configured as a
standard serial port and should be connected to a serial port on a computer or other
peripheral equipment. The required cable is an ordinary 9-pin serial cable having male
and female DB9 connectors. The StationPro routes this port to the selected transceiver.
The (industry standard) pinout of this connector is as follows:
