1892 1335 - Orion Radio Modem Operating Instructions - v2.9 / Aug 2009 91
Notes: This adaptor converts all four digital outputs to floating SPDT relay contacts.
The Alert output is a relay or open-collector output, depending on how the unit
was ordered, and is not converted.
If the Alert output is to be used, and is an open collector output, the 0V return is via PL1.
If LED indication is required when an output is in its energised state, 12V at up to 40mA must
be provided via connector PL1, which may be taken from the same supply as the Orion.
LEDs are labelled to indicate which port they refer to.
PL1 connections are: pin 1 : 12V DC
pin 2 : 0V
