Data sheet:
RS422/RS485 interface module
for old ISA cards and Com-Servers with BNC
Freely selectable serial interface
W&T interface modules equip devices having only a serial TTL interface with almost any desired standard interface type. In addition the modules allow you to adapt the interface types of many W&T devices over a wide range. The modification is done by simply replacing the standard interface modules with modules of the desired interface type.
