Subject:  Setting QLink Prefixes & Suffixes

Products Affected:  All QLink modules

All QLink motherboards are factory-preset to a prefix of ‘16’.  This default prefix of 16 was chosen because our first and second generation hardware used prefixes 1 to 15, so prefixes of 16 to 99 are unused.

In the rare instance that you need to change this prefix, follow these steps:

1.  With the power turned OFF to the QLink module, use a small pocket screwdriver to set the address dials to ‘00’.

2.  Turn the power ON and observe the FLASHING yellow LED (small light) on the motherboard, which is labeled SET ADDR.

3.   Turn the dials on the motherboard to the new PREFIX (probably 16 or higher) and wait approximately 5 seconds until the yellow LED stops flashing.  The PREFIX is now set.

4.  Turn the power OFF and set the motherboard dials to the SUFFIX  you have selected for this module.  Generally, you can use any number from ‘01’ to ‘99’ that is not being used by another QLink module on this same cable, or port.

5.  Turn on the power.  Your complete address for this module is now set.
