F&eIT Series Isolated RS-422A/485 1ch

Communication Module

COM-1PD(FIT)GY

* Specifications, color and design of the products are subject to change

without notice.

The COM-1PD(FIT)GY performs serial communication with an external

device in compliance with RS-422A/485, capable of serving as COM3 or

COM4 of an F&eIT series microcontroller unit.

The module can also serve as an expansion COM port for a media

converter [RP-COM(FIT)H, RP-COM(FIT)H-AF, or FX-DS540-COM2].

Features

RS-422A/485 serial communication ports

The communication lines are electrically isolated from the module.

High-speed communication is supported at up to 921,600bps

(115,200bps in compatible mode).

A baud rate can be set by software.

The module has 128-byte FIFO buffers for transmit and receive.

Driver software is supplied to allow the serial ports to be used as

standard Windows or Linux COM ports. *1

The data transfer mode (full duplex or half duplex) can be set by a

switch.

The board includes a 100Ω terminating resistor required for multi-drop

(party line) connections. The resistor can be inserted into the signal

line by a switch.

Surge protection is provided for each RS-422A/485 signal line.

Up to three units can be added (at the time of enhanced mode) as

expansion ports for micro controller unit. *2

Up to three units can be added as expansion ports for media

converters [RP-COM(FIT)H, RP-COM(FIT)H-AF, FX-DS540-COM2].

Similar to other F&eIT series products, the system, in the module itself,

incorporates a 35-mm DIN rail mounting mechanism as a standard

item. A connection to a controller module can be effected on a

lateral, stack basis in a unique configuration, which permits a simple,

smart system configuration without the need for a backplane board.

*5 When stacked in a media converter, the setting(s) depend on the media converter. For detailed specifications,

refer to the media converter's instruction manual.

When connecting the moduleto a controller module, the internal power consumption should be taken into

account. If the total current exceeds the capacity of the power supply unit, the integrity of the operation

cannot be guaranteed. For further details, please see the Controller Module manual.
