INSTALLATION
If you're replacing an existing board, begin at Step 1. If no previous VDB103/VDB103R board exists, begin at Step 6.
1 . When handling the VDB103/VDB103R, wear an anti-static wrist strap to avoid electrical damage to the board.
2 . Disconnect the drive-thru audio or timer system power adapter from its electrical outlet.
3 . Disconnect the loop cable from TB1 on the existing board to be replaced.
4 . Disconnect interconnect cable from its connector (P1) on the base station or control unit circuit board. Note the connector and
its location.
5 . Remove the existing board by lifting it off the plastic standoffs that hold it in place.
6 . Connect the loop cable to TB1 at the upper left corner of the VDB103/VDB103R. See Figure 1, above.
7 . Position the VDB103/VDB103R over the three plastic standoffs on the base station or control unit circuit board and press it
firmly until the standoffs snap through the holes on the VDB103/VDB103R. See Figure 1 for hole locations.
8 . Connect the VDB103/VDB103R interconnect cable to P1, at the lower right corner of the VDB103/VDB103R. See Figure 1.
Be certain the plastic catches on the cable connector are aligned with the plastic catches on the P1 connector. The color-
coded connector wires must also match the pin positions shown on Figure 1.
9 . Connect the other end of the interconnect cable to the circuit board in the base station or control unit per installation
instructions from the drive-thru audio or timer system.

10 . Reconnect the drive-thru or timer system power adapter to its electrical outlet.
11 . During boot up, "
" (for 'booting') will display for a few seconds. The Display on the VDB103/VDB103R should then read "

", indicating that the loop is signaling properly. If the Display does not read "
it still does not indicate "
12 . Drive a car onto the loop. The Dot on the Display should illuminate when a car is present over the loop.
NOTE: Adjust switches as needed before installing the VDB103/VDB103R.
If it is necessary to change the functions of the VDB103/VDB103R, refer
to the DIP switch settings on the next page. Normally, no changes will be
required.
