The controller provides a number of status LEDs. See Figure 10.
1 = WiFi (Green) - Lit whenever WiFi config switch is not Off.
2 = V-Net "B" (COM2): Transmit (TX) and Receive (RX).
3 = STAT (Green) - Remains lit. See "STAT (Status) LED".
4 = BEAT (Yellow) - "Heartbeat" LED that blinks at 1Hz during normal operation. See "BEAT (Heartbeat) LED".
5 = Primary Ethernet SEC (LAN1) "Link" (Green), "Activity" (Yellow). See "PRI, SEC (Ethernet) LEDs".
V-Net port B (COM2) has two LEDs reflecting the following port activity:
• Yellow (TX): indicates the controller is transmitting data on the V-Net port.
• Green (RX): indicates the controller is receiving data from an V-Net device connected to this port.
These LEDs use a fixed "on time" when a message is detected on the port. If a receive LED is on constantly, this can indicate a wiring prob-
lem, such as a shorted wire or reversed wiring.
