7. Set Unit ID Numbers (Multiple Unit Installations Only)
In a multiple unit installation, each unit must know its unit number and that there are other units
in the chain. If all units are not correctly identified, remote programming and remote gate
operations will not work properly. Set the unit ID numbers as follows:
♦ The unit connected to the phone line closest to the residence should be unit number 1.
♦ The unit connected to the phone line farthest from the residence and closest to the telephone
company has the highest unit number.
1. On the Crown Jewel front panel keypad, enter "
password. If the password is accepted, the Crown Jewel will respond with a programming
promt consisting of two short beeps.
2. At the programming prompt, select step 38, the position of this unit in the chain, the total
number of units in the chain, and the "#" sign. For example, if the unit you are currently
programming is the first unit in a four unit chain, you will enter "38 + 1 + 4 + #".
3. Repeat steps 1 and 2 at each of the remaining units.
4. After setting the unit ID numbers, verify that each unit was programmed correctly by entering
"37#" on its keypad.
•
The number of beeps emitted by each unit should match the number of that unit in the chain.
•
If the number of beeps matches the unit number, label that unit with its unit ID number for
future reference.
•
If the beep count is the same for 2 or more units, re-enter the correct unit ID numbers for those
units.
8. Hooking Up Optional CCTV
1. Plug the loose end of the coaxial cable into the monitor or television. NOTE: Maximum length of
coaxial cable should not exceed 100 feet.
2. When the monitor or television is turned on, picture will appear.

A. Make sure the connector is firmly attached to the power supply board.
B. The connector is keyed and must be attached in the correct direction. From left to right, the wires
