6.2.6 Analog / Digital connection

This connection is mainly used with the "Stand-alone mode". The analog interface of the LLB
measuring system is isolated from the rest of the device (see 6.2.4 "Shield and Ground" on page 115).
When using the analog interface, connect the analog ground (AGND).
Make sure, that the total resistance in the analog path is lower than 500 Ω.

6.2.7 External trigger connection

The DO1 (Digital Output 1) can also be used as digital input. For safety reasons, always use a resistor
to protect the connection terminal. The function of digital input can be configured by the command
"Configure digital input (sNDI1)" (chapter 10.3.5.2 on page 141).
