Notes:
1) The “External Supply” voltages on pin 3 and pin 9 are selected by the DC “Power Output”
jumpers, described in section 7.3.
2) Signals on pins 4, 5, 6, 7, 8, 11, 12, 13, 14 and 15 are with respect to the ground on pin 2, or if
pin 3 is selected to be “COMMS GROUND” by the DC “Power Output” jumpers, described in
section 7.3.
3) The +5V output on pin 10 is only with respect to pin 3 if the “Power Output” jumpers are set to
select “GROUND” – see section 7.3.
4) The Port-A RS232 signals on pins 5, 6, 12 and 13 are not present on this connector by default, as
internal connection jumpers must be fitted – consult factory for details

Notes:
1) RAT RS485 and PS2 data signals are not isolated, and are with respect to the SeaHub’s internal
power supplies “+5V” and “GROUND”.
2) An internal 150
Ω
termination resistor is fitted across the RS485 input signals (pins 3 and 4)
