RS-232C 2ch Communication Module
* Specifications, color and design of the products are subject to
change without notice.
This product, which performs serial data transfers to and from
an external device, can be used as an extpansion port for the
F&eIT series microcontroller unit.
This product can also serve as an expansion COM port for a
media converter [RP-COM(FIT)H, RP-COM(FIT)H-AF,
This product is equipped with two channels of
RS-232C-compliant serial I/O ports.
High-speed communication is supported at up to 921,600bps
(115,200bps in compatible mode).
A baud rate can be set by software.
This product has 128-byte FIFO buffers for transmit and
Driver software is supplied to allow the serial ports to be used
as standard Windows or Linux COM ports. *1
It corresponds to both the compatible and enhanced mode and
when an enhanced mode is selected, it is possible to use it by
occupying the one interrupt level per one unit.
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,
Similar to other F&eIT series products, the system, in the
module itself, incorporates a 35mm 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.

One unit can be added at the time of compatible mode

These items can be set by software.
Data transmission at high speed may not be performed normally depending on the
environment including the type of status of connected material of cable and environment.
For the "Driver Library API-PAC(W32)" on the supplied CD-ROM, the range is 15 - 921,600
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 module to 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.
