Ethernet Connector
The Ethernet connector on the Z Series is a standard RJ45 connector with 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 auxiliary
serial port serial data. Contact closure pins 2 and 4 are shared with the auxiliary serial port. To option remove the circuit
board and locate 3-pin headers JP1 & JP2 behind the green connector. Facing the end of the board containing the green
connector JP1 and JP2 should have jumpers center to right to use the discrete I/O (Din, Dout), and JP1 and JP2 should
have jumpers center to left to use the auxiliary serial port. Auxiliary serial port parameters (baud, parity, etc.) are set using
the RS232 screen. From the factory the unit ships with the auxiliary serial port enabled.
