converter is designed to support all types of RS232
and RS422 conversion needs. All defined pins are
supported on the RS232 and RS422 sides of the
interface. The only exceptions to this are the
voltage pins. The voltage pins are not connected
inside the unit.
The unit will support
synchronous uses like HDLC and support a hardware
handshake or software handshake. The unit supports
asynchronous operations using hardware or software
handshake. The pins, on both connectors, are
connected to jumper posts so they can be connected
internally to any of the other pins. The jumper
posts are setup so the RS232 and RS422 interfaces
can be setup for either a DCE or DTE interface using
shorting jumpers on the jumper posts.
