USB Interface
All devices in the ES-U-xxxx-x series feature a standard USB type-B socket. A standard USB A-B cable is
supplied to connect to the PC.
Serial Interface
The ES-U-xxxx-x converters have DB-9 male connectors for connection to the RS-232/422/485 interface.
Some models have the following additional features:
• Terminal block connections providing a subset of the signals
• Optional 5V output.
The ES-U-1032-RM unit has RJ45 connectors on the front panel instead of DB-9, but is provided with
adapter cables to convert these to DB-9 male connectors if required.
