5.2.10 Isolated Outputs, Group J52
This group is in the XT-3 pre-configured with cables to power (J31) and an M12-4
connector in the chassis to support the LEDs of the external antenna. If required the
pre-configuration can be removed and the group used for other purposes.
The group consists of two open collector outputs.

1 OUT 1C Output 1 collector
2 OUT 1E Output 1 emitter
3 OUT SPL External supply voltage for the outputs
4 OUT 2C Output 2 collector
5 OUT 2E Output 2 emitter
5.2.11 Ethernet, Connector P1
An RJ45 connector labelled P1, with two internal indicators, is provided for Ethernet
connection. The clip for detaching the cable faces upwards from the controller board
surface to allow mid-board mounts. The Ethernet connector has eight pins and the wire
scheme is based on the T568A standard.
