Clock IoT Connector Type B - User Manual

Modified on: Tue, 20 Feb, 2024 at 7:23 AM


Hello and welcome!

To be on this page means you have received the Clock IoT connector and need to install it. The purpose of the IoT device is to act as a communication bridge between Clock PMS+ cloud servers and local servers or third-party devices - these are access control systems (key cards); non-fiscal printers; fiscal printers and others.

Please note that one IoT device can communicate with multiple systems - for example, if you have a key-card system and a payment terminal, you only need 1 IoT device to communicate with both (as long as the requirements described below are met).

To achieve seamless and uninterrupted communication, you must strictly follow the instructions described here, especially those related to your local network settings.
