through each direction available with the array selection until the Hi-Z knob is pushed

again. One simple knob press returns you to the direction screen when using "Auto

Rotate".

Typical Output Switch Connections

out

RLY1 in the above schematic is showing the typical output connection used to switch

the CTRL lines for any Hi-Z Receiving array. Each line is optically isolated and fully

protected from over voltage, reverse voltage, and voltage transients. Caution should be

exercised to make sure any of these Switch Output lines are not connected directly to a

power supply voltage as the outputs are rated only for 200ma. DC. Hi-Z arrays are

typically using 40ma. DC Maximum switching current. It would be prudent to check the

current coming out of each CTRL line of the Hi-Z array before connection to the SS2. A

simple current meter connected between the Hi-Z array Ground and any of the CTRL

lines coming from the array should show the amount of current being switched.
