The TX (yellow) light indicates transmit activity. If this light is not on, troubleshoot the
Plant Information Network (PIN) cables and other interfaces.
There is a test jumper on the front of the NGI board (near the indicator lamps described
above). This jumper has two positions, TEST and NORMAL. This jumper should always be in
the NORMAL position when the network is operating. Placing this jumper in the TEST
position may disrupt operation of other nodes operating on the PIN.
