Expansion Board ES415 - Modbus
The connection to a monitoring system via Modbus RTU binary protocol
optional expansion board ES415 (PC-Card Modbus output).
The ES415 board is mounted on the main board, placed in housing cover.
Pay attention, to put the terminals into the connector on the motherboard, making the first, matching
the three click columns with the corresponding holes and then pressing to insert them.
The "H3 (D1)", "GND (Common)," and "L3 (D0)" terminals of the RS485 serial port (COM3) are to be
connected to the supervision system (Master) or dedicated isolated converter (not included).
On standard MODBUS system, all devices are connected (in parallel) on a distribution cable with 3
shielded wires. Two form a balanced pair of twisted conductors, on which the bidirectional data,
typically at 9600 bits per second are transmitted. The third conductor (if used) is the common to all of
the bus devices.
