Interface Centronics > RS422, Model 26000
Function
The W&T-Interface 26000 allows uni-directional connection of
peripherals equipped with an RS422 port to the parallel port on
a computer.
Setting the Interface
Before first using, the RS422 parameters for the interface need
to be set using the DIL switches inside the Interface housing.
The baud rate, data format and handshake procedure need to
be set to the values which the connected peripheral uses.
The DIL switch settings can be found in the following table:
baudrate SW2 SW3 SW4 SW5 handshake SW1
