USB and Serial Interface
USB Interface
Devices in the ES-U-xxxx-x series feature a standard USB type-B socket (with standard USB A-B cable
supplied to connect to the PC) or a USB type-A plug to connect to the USB port directly.
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.
