8 Link LED (disconnected by default- to connect a zero ohm
resistor needs to be placed)
9 GND
The ethernet connections are also labeled with their typical pin number in an 10/100 RJ45 cable (1,2,3,6).
Note that a power input connection is available which may be capable of powering the radio board in some cases.
This is pseudo-POE (Power Over Ethernet)- power is not shared with data lines but it may be sent over the
connector, if the voltage is high enough to keep total current low enough for the connector and ethernet cable
(typically 48V). Do not connect unless using this feature – note they will also mirror the input voltage if powered
from the main input power connector.
2.4.4 J5: Serial connector
This serial port can be configured as a transparent serial connection to a serial device, either with RS232 voltage
levels or 3.3V TTL voltage levels (with 5V tolerant inputs).
Note that the DIP switch S1 configures RS232 or TTL mode for this port.

Pin# Description
1 VCC +5V out
2 RX (Serial input)
3 TX (Serial output)
4 RTS
5 CTS
6 GND
2.4.5 S1: RS232/TTL mode DIP Switch
This DIP switch controls whether J5 operates in RS232 or 3.3V TTL mode.
Only one of the switches should be enabled at a time (do not turn both switches to ON mode).
