Active termination for 1-Wire networks

In a 1-Wire network, the 1-Wire Term 1 provides a defined termination at the end of the 1-Wire network, thus ensuring a stable and professional 1-Wire network. The 1-Wire Term 1 is therefore a basic component of every 1-Wire network. The module contains a passive and active terminating resistor and a signaling of bus activity.
The active termination (1-Wire Term 1) is highly recommended to increase the maximum line length and improve the system stability of the 1-Wire network, especially for long 1-Wire lines and for a star or tree topology setup.

In a 1-Wire network, up to 3 1-Wire Term 1 modules can be connected.

The 1-Wire Term 1 is very compact and can be ideally installed in a flush-mounted box.

Scope of delivery Module and operating instructions

Integration into 1-Wire network

The 1-Wire Term 1 module is mounted at the end of a 1-Wire network cable.
If the 1-Wire network is star-shaped, i.e. with several 1-Wire cable sections, a 1-Wire Term 1 module should be connected to each end.
You should not use more than three 1-Wire Term 1 modules in a 1-Wire network.

Linear Topology

The structure corresponds to the linear topology with the difference that the slaves are connected to the main line via cables with a length of more than 3m (branch, stub).

Star or tree topology

The network is divided into several large strings at or near the 1-Wire bus coupler / 1-Wire controller /1-Wire hub (bus master). Sensors and actuators (e.g. switching modules) are connected at the end or along the respective string.
