M1XSP options are set by the placement of black shorting plugs on gold plated jumper pins . Some have 3 pins with a selection of "0" or "1".
Some have only 2 pins with a selection of Off or On. Options vary by manufacturer. Refer to detailed installation and hookup diagrams.
** Jumper S4 for future expansion, shown for reference only. Current M1XSPs do not provide this jumper.
The equivalent value of position S4 with no jumper is a 1.
Jumper S5 was not included on very early product units.
* In the INSTEON mode S5 has an alternate setting of
1
to allow more X-10 units in lieu of INSTEON groups.
$ For S8 selects whether a "request node status" (poll) command is sent.
Other Jumper Settings
JP1
Used to engage a 120 Ohm resistor for terminating the M1 RS-485 Data Bus. See M1 Data bus wiring instructions before use.
JP2
Used to engage a 120 Ohm resistor for terminating the 'Outbound' (External) RS-485 Data Bus if required by other manufacturer.
JP3
Selects either RS-232 or RS-485 format communications on the 'Outbound' connections. Jumper Left = RS-232, Jumper Right = RS-485
JP4
Not used
JP5
Used to 12V to pin 4 (DTR) of the DB9 Female connector for certain modes. This jumper can typically be left on always.
