Appendix B – System Conguration (Using Conguration Software)

The Wireless I/O Extender is made up of two components: the microprocessor and the RF transceiver (radio) each one

congurable. The microprocessor conguration parameters are stored in local memory and the radio conguration is

stored in memory local to the radio. The conguration can be changed using serial commands via port P3. The easiest

method is to use the Data-Linc Group program provided with the master unit, to be run on a PC. If the program

(io_cong.exe) is missing it can be downloaded from the Data-Linc Group web site ftp://ftp.data-linc.com or it is possible

to change the settings using a PC with a terminal program (See Appendix C). The settings need to match in all the units in

the system, mis-congured units will not answer and the status LED will be lit or blink to indicate a system problem.

Change I/O Configuration

Remove all the connectors from the Wireless I/O Extender.

Remove the 4 screws on the top to remove the cover.

Connect the programming serial data cable from PC to Mini-Din connector (P3).

Note: This cable should be supplied one per system, available from Data-Linc Group.

Set the switches to “PIC Cong” (3&4 ON, 1,2,5&6 OFF).
