- Dual-color LED 3: Link indicator — green for link established, red for link lost.
- Dual-color LED 4: Ethernet port 1 indicator
- Dual-color LED 5: Ethernet port 2 indicator
Interface Configuration
- Power: XT30PW-M, GND/VCC
- Ethernet 1 & 2: PH2.0-4, RX-/RX+, TX-/TX+, 10/100M Ethernet
- Dual RS232 Serial Ports: PH2.0-6, R1/GND/T1, R0/GND/T0
- Single TTL Serial Port: PH2.0-3, R2/GND/T2, TTL 3.3V
