Fixed issue with some links and updated all
links in document.
Set to revision 1.1 as this is a minor change
compared to 1.0.
Added “Twisted pair wires are required for each
signal pair.” in paragraph above each RS422
and RS485 wiring diagram.

Added section for ES-U-2001-A and ES-U-
2101-A.

Added ES-U-2001-A and ES-U-2101-A to the
lists of products throughout the document
Updated part numbers to ES-U-2001B and ES-

Standardised for all sections that only Rx
biasing should be used when an RS-485 half-
duplex network required biasing. Previously,
some sections recommended Tx only and
others recommended Rx only. Either would be
OK but updated this to keep it consistent
across all models.
Reviewed and minor mods made.
