AVDB THEORY OF OPERATION
DRAFT
The AVDB uses digital signal processing techniques to assess parameters inherent to inductive ground loops in order to evaluate
loop status and signal vehicle detection. As a loop operator, this technology affords you the benet of understanding the quality of
your loop in real-time with advanced foresight and warning of deteriorating conditions.
This allows preventative measures to be taken to avoid down time and situations in which your drive-thru technologies and
services are hindered or incapacitated due to a failed or failing loop. While these events are unlikely, the advanced warning
system of the AVDB offers peace of mind that drive-thru operations will continue to be uninterrupted.
Through continuous measurement of the inductive ground loop, the AVDB determines the inherent electrical characteristics of
the loop which include: loop condition, connection quality, and the inductance of the loop. These three parameters are evaluated
to determine the Loop Status as seen in Figure 4, page 6. In the case of a deteriorating loop, the AVDB offers insight into the
underlying cause and the course of action to help troubleshoot your issue.
The vehicle detection portion of the AVDB operates through analysis of loop response to a stimulus provided by the detector,
which characterizes the inductance of a loop. The presence of a vehicle over the loop electromagnetically interacts with the loop
causing a change in inductance. The AVDB monitors these small inductance changes in order to signal vehicle detection.
LOOP FAILURE AND INTERFERENCE
Inductive ground loops may eventually fail. The AVDB can remove the surprise of failure from operation and allows you to prepare
for such an event well in advance. Loop failure is the result of damage to the loop which can include, but is not limited to: damage
to area surrounding loop, severed loop or lead in wires, or insulation damage as a result of aging and other environmental factors.
In addition, deteriorating connections between the loop and the AVDB can cause detection failure even though the loop itself is in
good condition.
The AVDB is essentially a large metal detector. Do not install the loop over any metallic object, surface, or area. This includes
installing the loop over rebar. Failure to adhere to this installation recommendation will result in unexpected loop behavior.

INSTALLATION
If you’re replacing an existing board, begin at Step 1. If no previous ADVB board exists, begin at Step 6.
1. When handling the AVDB, 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 AVDB. See Figure 1, above.
7. Position the AVDB over the three plastic standoffs on the base station or control unit circuit board and press it rmly until the
standoffs snap through the holes on the AVDB. See Figure 1 for hole locations.
8. Connect the AVDB interconnect cable to P1, at the lower right corner of the AVDB. 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.
h If the installation instructions are not available, visit hme.com to obtain the manual PDF le or call HME at 1-800-848-4468.
10. Reconnect the drive-thru or timer system power adapter to its electrical outlet.
11. During boot up, “b” (for ‘booting’) will display for a few seconds. The Display on the AVDB should then read “0”, indicating that
the loop is signaling properly. If the Display does not read “0”, be certain all connections are tight. If it still does not indicate
“0”, see Figure 3, page 6.
12. Drive a car onto the loop. The Dot on the Display should illuminate when a car is present over the loop.

REGULATORY LABEL PLACEMENT
DRAFT
The Regulatory Label included in the installation package must be placed on the side of either the Base Station or TSP
(depending upon which of the two the ADVB board is installed).

Before installing the AVDB, the following six functions can be set by switching/moving the switches as indicated below. Refer to
Figure 3, below.

to slower detection at the risk of small

TROUBLESHOOTING
DRAFT
Release Sensitivity
h Set to Low if multiple detections or dropouts occur frequently at Normal.
h Set to High or Extra High to compensate for improperly positioned loops where run-ons occur.
h Set as low as practical. Check for run-ons or dropouts and set for best operation.
RESET PROCEDURE
If the detector is stuck indicating a vehicle present continuously or is otherwise unresponsive, follow the reset steps below:
With no vehicle present over the vehicle detector loop:
h Press and hold the Reset switch in the base station or timer for 1 second and then release. The ADVB display will go blank
for a few seconds and then should show “b” for a second or two.
h Reset is complete when the ADVB display shows a code other than “b” or “F”.
DETECTOR FUNCTION
To verify proper detector board function, disconnect one of the wires to the detector loop and verify that the board display changes
to “d”. Then reconnect the wire and the display should change back to one of the normal codes. If the display was originally
showing “d”, short the two loop terminals and watch for the display to change to “C”.

SELF DIAGNOSTICS

US Compliance Notice
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Model RFM100 is a module transmitter that is installed inside a host or nished product. It was certied with single modular approval per Federal Communications
Commission (FCC) CFR47 Telecommunications, Part 15.212 under Subpart C Intentional Radiators. Single modular approval does not necessarily eliminate FCC
testing on the nished product. For example, FCC Part 15 B requirement for the digital device (unintentional radiator) of a composite system, RF Exposure and/or
Co-location requirement may still be applicable to the nished product.
The host integrator is responsible to ensure that the nished product complies with all applicable FCC equipment authorization regulations.
The FCC certication of the module transmitter is voided if the host integrator does not follow its FCC’s grant notes and operation condition/installation instructions.
This module transmitter contains an integrated antenna, which is also integral to its FCC certication, so using any other antenna would void its FCC certication.
This module transmitter must not collocate or operate simultaneously with any other antenna or transmitter within a host device, except in accordance with FCC
multi-transmitter procedures.
If the FCC ID of this module transmitter is not visible when the module transmitter is installed inside a host or nished product, then the exterior surface of the host
or nished product must also display a label with the following or similar wording: “Contains FCC ID: BYMRFM100”.
