Recovery function Firmware-update
Should an error occur during the firmware update e.g. losing power while updating the
firmware, a recovery function can be started. Press and hold the reset button (the reset
button is located beneath hole no. 30 at module top side). Then start the update in Config-
Tool 3 and release the reset button after 1 second after the update has been started. The
update should start now.
When the updated is completed we recommend to disconnect the 1-Wire Controller /
1-Wire Gateway for approx. 30 seconds, then restart again. If any issues should occur
when installing the update, please contact the ESERA support team: E-Mail:

Communication
16.1 ESERA ASCII text protocol / programming manual
The 1-Wire Gateway 20 Modbus provides two types of protocols. The ESERA text protocol in ASCII format
easily supports configuration and analysis whereas the ESERA text protocol runs on "GET" and "SET"
commands. The ESERA text protocol is totally open and documented. The latest version of the ESERA
protocol description is available for download in our webshop
(https://www.esera.de/produkte/software/downloads-firmware-1-wire-controller-1-wire-gateway/) as well as in
the ESERA Config-Tool 3 download area.

1-Wire Gateway 20 Modbus communication to ESERA text protocol or Modbus TCP protocol is parallel with
no switching. For communication any IP address and any port can be chosen. Default is set to port 5000 and
CHCP mode.
