OPERAND USAGE: _SIn contains the state of the status bits in decimal form
where n specifies an axis A-H.
*The sign of the p argument of the SI command configures the Galil hardware to store
each data bit to the Galil registers upon either the next "rising" or "falling" edge past the
current clock pulse. It is suggested that the edge type is configured as the same type as
the encoder trigger (consult your specific encoder documentation for details).

SSI ENCODER SIGNAL CONNECTIONS:
There are a few interface options to gain access to the SSI Signals, which depends on
the model of the controller:
· For the DMC-1700 /1800 /18x2 /34x5 /14x5 using the DB-14064-SSI the signals
are accessed via two 50-pin IDC headers (at J6 & J8).
· For the DMC-21x2/x3 using the DB-28040-SSI, signals are accessed via two 20-
pin IDC headers (at J4 & J5).
· When using a DMC-2x00-SSI Optima series controller, the signals are accessed
via the 80-pin SCSI type extended I/O connector. Using the CABLE-80-1m cable
to a CB-50-80 converter will allow signal access using two 50-pin IDC headers
labeled J6 & J8.
· The Phoenix Contact MD/80 module offers screw terminals, which directly
connects to the CABLE-80. Note: this option can also be used with the CB-50-80
installed on the DB-14064-SSI.
Each encoder requires 4 signal wires: Data+*, Data-*, Clock+, and Clock-. Pinout
locations in Table-1 are noted as <connector> - <pinout>. The pin number assignment of
the IDC header alternates, with the odd numbers along one side of the two row header
and the even along the other. Pin #1 is noted with either an arrow on the IDC housing or
a "1" on the board silkscreen. The SSI pinouts in Table-1 do not apply to the DMC-2100
(obsolete); contact Galil for a correct pinout.
