Input field wiring notes
In electrically noisy environments, we recommend using shielded multi-conductor I/O cable as well as
a shielded backshell when connecting field wiring to Flyer’s DB-25 User Interface connector.
To minimize ground loop noise, ground the cable shield at the signal source only. The cable shield at
the User Interface connector must be left floating unless you are using Flyer’s +15 VDC auxiliary power
output as the I/O signal source.
