Section 2.  Installation and Hardware
Set-Up
The
 
SDM
-
SIO4
 
is
 
designed
 
to
 
be
 
mounted
 
on
 
an
 
enclosure
 
chassis
 
plate
 
using
 
the
 
two
mounting
 
holes
 
in
 
the
 
tabs
 
on
 
the
 
side
 
of
 
the
 
case
.
Before installation, it is necessary to set up the address of the SDM-SIO4 and also the mode
of operation of each serial port. These settings are determined by jumpers inside the case. To
access these, remove the four M3 screws and lift the lid off. With the connectors facing you,
you will see two blocks of jumpers on the right hand side of the circuit board.
Turn off the 12V supply and take static prevention
precautions before removing the lid.
2.1  Setting the SDM Address
The 4 x 2-way block of jumpers close to the ‘D’ connectors selects the SDM
address of the SDM-SIO4. This address ranges from 0 to 15. The four selector
blocks are numbered on the PCB silk screen as 1, 2, 4, and 8; ‘8’ is closest to the
‘D’ connectors. This is in binary format as shown in Table 2.

NOTE:  A ‘1’ means the selector block shorts both pins. ‘0’ means the selector is
only connected to one pin (for storage).
