Synapse remote I/O module
The Synapse module (further reffered to as 'module') is produced under 7bit trademark and designed for data aquisition from discrete sensors and 1-Wire temperature sensors, as well as load control with digital outputs.
The module has 2 Ethernet interfaces (working in a “bridge” mode) for LAN connection and supports Modbus TCP & MQTT protocols. The enclosure is for panel / DIN 35 mm mount.

033 - number of 1-Wire sensors on the bus, writing '0' - resets sensors enumeration tree and makes new enumaration, old sensors will be deleted, writing any number but '0' - leaves old enumaration tree and appends new sensors to the end
