Operating Voltage. Depends on the assembled power module:
+3...9 VDC (Only for SATELLINE-EASy) / +6...30 VDC
Note!
Unused pins can be left unconnected.
Note*)
RTS and CTS signals apply to the selected Data port (either Port1 or Port2).
Note**)
Programming Mode is for changing the settings of the radio modem via Programming
menu. Normally the MODE line is NOT connected i.e. the modem is in Data Transfer Mode.
