Reset button and Ethernet cable termination
It is essential that the Ethernet cables used be the correct type of cable and terminated with
the correct pinout. The cable can be terminated as either a patch cable or a crossover cable
and must be properly terminated relevant to the application (see
Ethernet Control on
page 106 for termination details).

NOTES:
• See SIS Configuration and Control on page 34 for SIS command definitions
or SMX Control Software on page 59 control software details.
• The SMX can support either RS-232 or RS-422 serial communication protocol,
and can operate at 9600, 19200, 38400, or 115200 baud rates
(see
Operation on page 13 to configure the RS-232/RS-422 port).
Input and Output Boards
The I/O boards on any unit may vary with each installation, depending on desired
configuration and use. All board types have the input and the output connectors clearly
marked, and each board has a 16-position rotary switcher (see m, figure
2 ) for setting the
I/O plane address. An LED on the board indicates when power is present.
NOTE: Boards with the same plane address switch simultaneously.
Figure 2 shows some, but not all, board variations that can be installed into an SMX frame.
Boards have different combinations of input and output connectors, depending on the
specific board installed. To install any board into an SMX frame slot (see
SMX Frame and
I/O Board Installation on page 10).
NOTE: Control signal ground pins may be labeled as or “G”. Audio ground pins may
be labeled as or . The wiring and function are the same, whichever way your product
is labeled.
