LKM S1 - Communication Interface USB ↔ TTL
The LKM S1 communication interface can be used to communicate with the majority of our digital measuring devices. This means that the parameters of the respective measuring device can be easily set individually on the Windows PC. It is also possible to retrieve various data and operating statuses from the devices. The software required for this can be downloaded from the store under the relevant devices.
The interface has a USB-C connection and electronics that ensure galvanic isolation of input and output. The devices are connected to the output with the A1, A2 or A3 adapter cable. With the supply voltage of 8 V, which is also galvanically isolated, most measuring devices can also be configured without a separate power supply. Operational readiness is indicated by a blue LED. A device driver must be installed during installation.
