● The termination jumpers are there to ensure correct 120 Ohm
termination to the serial ports. These will all be fitted by default but if
a port requires no termination then that port’s jumper can be
removed.
● Secure the accessory cables within the junction box with cable ties
(not supplied).
● Refit the lid securely to ensure the waterproof integrity of the unit.
