(iii) Mounted to the rear panel is the interface board to the serial connectors. This has 4 small jumper
connections, two of which will determine whether pin 9 and pin 8 can be used to accept the PPS signal.
There are also two disconnected jumpers at the top of the board - do not change these.
(iv)
The small black connector bridges the two pins when connected, and sits on only one of the pins
when disconnected. Below we can see the default, pin 8 (JP4) is disconnected on the right and pin 9
(JP3) is connected on the left.
(v) To disable pin 9, remove the jumper connector from both pins and reattach to a single pin.
(vi)
(If required) to enable pin 8, remove the jumper connector from the single pin and attach to both
pins.
(vii)
Re-align the rear panel with the RTA housing, ensuring that the O-ring seal is correctly seated in
the groove on the rear panel. Insert the 7 bolts into the rear panel and tighten with the allen key.
