Having completed the receiver board assembly, as described last month, it can be housed in a UB3-size utility box. As shown in the photo last month, it simply clips into place but first you will need to drill a hole in one end for IRD1, plus a hole in the other end for the external wiring.

You will also have to drill matching holes in the lid for the Ack/Power and Arm LEDs (LEDs1 & 2).

Now for the initial set-up. First, install a jumper link in the minus (-) position for LK2. This will set the Strike2 output to toggle mode (note: LK2 must always have a jumper connection, either to the "+" or "-" position). Leave jumpers LK1, LK3 & LK4 out for now.

Next, set trimpots VR1 & VR2 to mid-range. These trimpots are later used to set the various time periods.
