1.4 ELECTROSTATIC DISCHARGE (ESD) PROTECTION
The ACR II contains electronic components and assemblies subject to damage by ESD. The ACR II was designed
to protect against ESD while the unit is closed and in normal operation. Proper handling procedures must be
observed during the removal, installation, repair and other handling of printed circuit board assemblies, electronic
devices and components to include:
1) Service to be performed by authorized personnel only.
2) The person performing the service must be grounded by an ESD grounding strap.
3) While performing maintenance or repair, touch an unpainted metal of the ACR II surface prior to
touching or handling any printed circuit boards or electronic components.
4) Printed circuit board assemblies must be placed in and transported in conductive bags or other
conductive containers.
5) Printed circuit boards must not be removed from the conductive container until time of use.
6) All other “best” practices for protecting devices from ESD must be observed.

- ¼” Flat Head screw driver is required for tightening cover screws
2.1.2 SERVICE AND REPAIR
- #2 Philips screw driver for circuit board removal
- #2 Philips screw driver for card reader removal
- ¼ Flat Head screw driver for hinge removal
- 5/16 Nut driver to remove LED PCB and PROX bracket stainless steal.
2.2 COVER CLOSURE AND BOLT REPLACEMENT
When closing the cover gently lift on the bottom of the cover when in position for starting one or two of the right
corner screws. This is done to assist in alignment of the cover and base holes for starting the screws. The enclosure
cover is secured to the housing by four 6mm slotted/Philips screws. When the screws are removed, the front cover
will swing left and hang from its hinges. The screws are captive and will remain with the cover.
2.3 MOUNTING THE ACR II ENCLOSURE
Exterior dimensions of the standard ACR II enclosure are shown in the Appendix, see figures 7.2-7.4. There is only
one mounting orientation possible reference figure 7.1 for ACR II Mounting Template. The cable entries are located
at the bottom of the unit.
Appropriate fasteners must be selected to support the minimum weight of 10 lbs (4.6 kg). Toptech offers the
following mounting suggestions for three typical surfaces: drywall, wood or concrete/cinder block.
2.3.1 DRYWALL
Insert four fasteners through the corner mounting holes, shown in Figure 7.2. For the fasteners, use #12 x 1” (M5
x 25 mm) Phillips pan head sheet metal screws inserted in #12 (M5) self-tapping nylon anchors.
Place one #12, 3/8” OD (M5, 10 mm 0D) flat washer under the head of the screw before inserting the screw into
the mounting hole.
2.3.2 WOOD
Follow the instructions above for Drywall installation, but substitute #12 x 1” (M5 x 25 mm) wood screws for the four
sheet metal screws. Do not use the self-tapping nylon inserts.
2.3.3 CONCRETE OR CINDER BLOCK WALLS
Follow the instructions above for Drywall installation, but substitute a 1/4 ” x1 1/4” Tapcon masonry fastener for the
four sheet metal screws. Do not use the self-tapping nylon inserts.
Drill pilot holes for the Tapcons using a 3/16” x 3 ½” masonry drill bit.

ACR II Installation Guide: 20180711 Part # 6057
2.3.4 MOUNTING HEIGHT CONSIDERATIONS
The following factors should be taken into consideration when deciding where to mount the ACR II
control Unit.
The ACR II unit should be positioned for convenient access to the front panel and mounted in a
vertical, upright position. Try to mount the unit approximately five feet above the floor so that
the card reader can be accessed from a comfortable position.
The ACR II is housed in a Type4, IP65 enclosure. It should never be submersed in liquid.

2.5 ELECTRICAL SUPPLY CONNECTIONS
The ACR II is equipped for 85 -250Vac operation.
Use field wiring rated 75ºC or greater.
Do not route AC and DC wiring in the same conduit.
All wiring must enter the ACR II enclosure through conduit via entries in the bottom of the enclosure. All conduits
must be terminated at the enclosure by use of appropriately rated conduit hubs or glands.
Wires must be stripped ¼” and fully inserted into terminal block with no bare conductor exposed. See section 2.4
for recommended wire size and torque values.
The unit requires a safety ground connection as described in section 2.5.2 below.
A service loop is recommended for all wires and cables entering the enclosure.
Do not allow service loop cables to overlap the circuit boards. Coil any cable length in the
bottom of the enclosure. Keep AC wiring separated from all other wiring in the enclosure.
Wiring must comply with all local electrical codes.
2.5.1 INPUT POWER
Provide over current protection using a 15 Amp circuit breaker or equivalent. The breaker also serves as a means
of disconnection from the operating supply as required by UL/ISA/IEC 60950-1 and CAN/CSA-C22.2 NO. 60950-
1.The disconnect device may not be blocked or be made difficult to operate by the ACR II or any other device. Note
that installation of disconnects are typically prohibited in Class I, Division 2 locations.
Power required: 85 – 250 Vac, 47 – 63 Hz. The power connector (TB1) is located in the right hand corner of the
ACR-FID_COMBO board as shown in figure 2.2. Select supply wire rated 300V or better with a flammability rating
of at least VW-1. See figure 2.3 for wiring guide for TB1.

ACR II Installation Guide: 20180711 Part # 6057
CHAPTER 3 DATA COMMUNICATIONS INTERFACE
The ACR II has one serial communication port (see Figure 2.2). This allows for communication with a Host device
(such as TMS) with a choice of either 232 or 485.
3.1 COMMUNICATIONS PROTOCOL SELECTION AND CONNECTION
3.1.1 RS-422/485
RS-422/485 communications protocol is designed for multi-point (i.e. computer to multiple devices, also called multidropped) communications up to 4,000 feet (1,220 Meters).
RS-422 requires 4-wires (2 twisted pair) for full duplex communications and utilizes a transmit pair of wires (TDA &
TDB) and a receive pair of wires (RDA & RDB).
RS-485 requires 2-wires (1 twisted pair) for half duplex communications and utilizes a single pair of wires (TDA/RDA
& TDB/RDB) for transmit and receive.
This manual will typically refer to both RS-422 and RS-485 as simply RS485 2 wire or RS485 4 wire.
A ground wire is not required, though some devices may have a terminal block for a ground.
Wire used must meet the following characteristics:
24 AWG stranded.
4-wire, two twisted pair with overall shield.
2-wire, one twisted pair with overall shield.
30 pF maximum between conductors.
1,000 ohm impedance.
Maximum length: 4,000 feet (1,220 Meters)
Maximum stub length: 15 feet.
All exposed shields must be properly insulated to prevent short circuits.
All shields must be continuous, soldered, and properly insulated.
3.1.2 RS-232
RS-232 protocol is designed for point-to-point (i.e., computer to a single device) communications limited to 50 feet
requiring a minimum of 3 wires – transmit, receive and ground. Additional wires are required for hardware
handshaking when using printers and data loggers.
Wire used must meet the following characteristics:
24 AWG.
3 conductor with overall shield (data only) or 8 conductor with overall shield (full handshaking).
30 pF maximum between conductors.
If a service loop is used, the maximum wire length in the service loop should not exceed 3 inches
[75mm].
Separate AC and DC wiring by at least 3 inches [75mm]. Do not allow excess wire in the service
loop to overhang printed circuit board.

ACR II Installation Guide: 20180711 Part # 6057
5.2 ACR II COMMUNICATION CONFIGURATION:
Configuring the communication parameters of the ACR II is accomplished by setting the DIP switches SW1 and
SW2 (see Fig 4.2). The switches are located on the upper right corner of the PC board (see Figure 2.2).
The switches are used to configure ACR II baud rate, parity address, captive or non captive, and the
communication protocol (open protocol vs proprietary protocol). Baud rate and parity are set using the first five
switches of SW1. Address is set using the eight switches on SW2.
Note: if using a TMS6 system, S8 should be set to OFF. Otherwise S8 should be turned ON to enable open protocol.

CHAPTER 6 SERVICE AND REPAIR
6.1 ACR II TROUBLESHOOTING
The following are suggestions for basic ACR II troubleshooting by qualified ACR II customers. If problems cannot
be resolved within a reasonable time frame using these methods, please contact your Toptech Account Manager,
who will facilitate resolution in a timely manner.
Note: Refer to figure 2.2 ACR-FID_COMBO board for LED locations for 5V, RX and TX LED. To view status light
on Prox reader the ACR II cover will need to be opened. The status light on an RP15 is found on the bottom of the
reader (refer to figure 7.12). On a Thinline II reader the card reader will need to be dismounted from the Card Holder
to view the status light on the front of reader (refer to figure 7.13).
Symptom/Condition
Possible Solution/Fix
ACR-FID COMBO board and Communication Problems
If the 5V LED on the ACR-FID_COMBO board is not
illuminated…
Verify the mains power is good.
If the RX LED on the ACR-FID_COMBO board does
not flash when COM commands are sent…
Verify the RDA/RDB or RX/GND serial connections
and polarity back to the host.
If the TX LED on the ACR-FID_COMBO board does not
flash when COM commands are sent…
Verify COM settings and address on the ACRFID_COMBO dip switches.
If no communication is received back at the host when
COM commands are sent…
Verify the TDA/TDB or RX/GND serial connections and
polarity back to the host.
As an additional diagnostic tool, enable the ACR’s Com
Diagnostic Mode by setting the S2 Dip #6 On. When
enabled, an identification string will be transmitted once
per second back to the host. (See Warning below.)
Card Reader Operation Problems
If the card reader does not flash green when a card is
swiped…
Try again with a different card.
If the card reader status light flashes green when the
card is swiped, but neither YES nor NO lights turn on…
Verify that the TMS gate in question is enabled and
running.
If the card reader status light flashes green when the
card is swiped and the NO light turns on…
Verify that the card is valid in the host database.
If the YES lights, but access is not granted…
Verify the TMS gate or Opto configuration, and verify
ACR relay connections and specifications.
Because of the possibility of message collisions, Com Diagnostic Mode should not be used
during normal operation.
