Status LED’s (continued)
Ethernet Status LEDs (continued)
Network Status (NS) LED
The Network Status LED is a bi-color red/green LED. The state of the LED depends on the protocol the
NX2A4E2 is configured to for.
Table R1.4 Network Status LED States
Link1 and Link2 LEDs
These are the Link Activity LEDs for the two ports. They are amber LEDs that are on when a valid hardware
connection exists on the port and blinking when data is being transferred over the link.
Input Status LEDs
These two red/green bi-color LED’s are used to indicate the on/off
status of the BRAKE and PRESET inputs. Note that the PRESET
function is not presently implemented. LED 2 will come on when
power is applied to the PRESET input, but the NX2A4E2 will not
change any position values. The BRAKE input is tied to channel 1.
When this input transitions from on to off, the unit starts a timer
and stops the timer when it does not detect a change in position on
channel 1 for 125 milliseconds. It then reports this time over the
network along with the channel 1 position when the input transi-
tioned. See
Stop Time Monitoring found on page 9, for a complete
description of how the brake input is used.
