Connect to the digital inputs
The analyzer can receive a digital signal from an external device, such
as a flow meter to stop measurements when flow stops. Each discrete
input is used to enable/disable the corresponding sample channel.
Each digital input can be configured as an isolated TTL type digital input
or as a relay/open-collector type input. Refer to Figure 15. By default, the
jumpers are set for isolated TTL type digital input. Refer to Wiring
connections overview
on page 13 to connect the device.
