3.4.4 Connecting the Signal Cable (Digital I/O)

To connect external devices to the digital I/O ports, use the appropriate mini-DIN cables (part
no. 6074.0001).
1. Plug the 6-pin connector of the mini-DIN cable into the Digital I/O port A (or B).
2. For each relay output or digital input to be used, connect the appropriate signal wire
and ground wire to the corresponding connectors on the external device
(→ documentation provided with the external device).
3. Make the required settings for the analog outputs in Chromeleon or on the front panel
display.
In Chromeleon
In the Properties dialog for the detector in the Chromeleon Server Configuration
program, enable the corresponding relay outputs on the Relays page (→ page 46) and the
corresponding digital inputs on the Inputs page (→ page 46).
On the front panel display
Select the Configuration menu and make the required settings under Digital output and
Digital input.
