2Ch Isolated RS-422/485 Interface Board for ISA

This product is an interface board external equipment, PC/AT which performs serial data transmission, and for the compatible machines. This board is used inserting in the expansion slot or I/O expansion unit of the main part of a personal computer.

	Transmission of the serial data of two channels can be performed on this one interface board.
	It has the serial input-and-output port of RS-422A/485 conformity two channels.
	A setup of a transmission rate can be set up by software out of 50-921,600bps. Moreover, the transmission rate of a channel 1 and a channel 2 is independent, and can be set up.
	Surge protection of all the RS-422A / 485 signal lines is carried out.
	Since it is isolated between the channel 1 and the channel 2 between the serial communication port and the personal computer, bad influences, such as a noise from the outside, are not received.
