2.3 Connectors
Ethernet Connectors
Connectors are found on the back of the Series 4200E SkyRouter. Ethernet ports 1 – 4 are auto polarity sensing and can
be used with either a standard Ethernet cable or a reverse (cross over) Ethernet cable.
Terminal Block
Connector J1 supports four separate functions, power, relay contact closure detection, relay driver output, and application
port serial data. Contact closure pins 2 and 4 are shared with the application serial port. To option remove the circuit
board and locate 3-pin headers JP1 & JP2 behind the green connector. To use the discrete I/O (Din, Dout) JP1 and JP2
should have jumpers center to right. To use the application serial port JP1 & JP2 should have jumpers center to left.
Application serial port parameters (baud, parity, etc.) are set by the application program using the port.
The pin out configuration is as follows:
Pin 1 – Din – Discrete Input (See Appendix A)
Pin 2 – Din Src – Discrete Input Source (See Appendix A) or RxD of application port.
Pin 3 – Dout Gnd – Discrete Output Ground (See Appendix A)
Pin 4 – Dout - Discrete Output (See Appendix A) or TxD of application port.
Pin 5 - Ground
Pin 6 - +12VDC
