1. Confirm that the driver has been set to the SECONDARY mode
(see page 12). In this mode the driver follows the signal sent from the
primary or perimeter loop driver.
2. Connect an RJ45 cable between the expansion jack of the primary/
perimeter driver and the expansion jack on the secondary driver.
Note: if connected to a primary driver the driver outputs are 90
degrees out of phase (for a phased array).
3. Nothing should be connected to the LINE or MIC input jacks on the
back of the secondary driver, and the input controls are not used on
the secondary driver apart from the drive level.
4. To enter the "Adjustment Mode" push the DRIVE ( + and - ) buttons
simultaneously until the status light begins to flash on and off.
5. If setting up a phased array bring the current level up until the
DRIVE output lights from primary and secondary driver match, after
releasing the controls. Note: there are 8 button pushes between each
output light. In the phased array you want the same signal level in the
centre of the secondary loop as you have in the primary.
Assumes unit is properly connected and loop has continuity.
