Installation and Hardware Set-Up | Campbell Hausfeld SDM-SIO4

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.

CAUTION 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.

			Table 2	Address Settings
Selector Block Settings				SDM Address
8	4	2	1
0	0	0	0	0
0	0	0	1	1
0	0	1	0	2

1	0	1	1	11
1	1	0	0	12
1	1	0	1	13
1	1	1	0	14
1	1	1	1	15

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