1600A-N1P
3.6 Setting Device Identification on the I/O Modules
NOTE: If your Model 1600A controller has been configured at Detcon, you may elect to skip to the
Operator Interface (Section 4.0) for further review of system operation.
For a unit that has not been properly configured, the I/O modules must be serially addressed to establish
correct communications. The I/O module’s identification is established by setting the two rotary switches to
the correspondingly correct position. The top rotary switch sets the most significant bit (MSB). The bottom
rotary switch sets the least significant bit (LSB). For an address of 01, set the top switch to 0 and the bottom
switch to 1. See Appendix B for Decimal to Hexadecimal conversion.
NOTE: All addresses must be unique. There can be no duplication of addresses or a failure to
communicate will occur. See section 4.1 for addresses
