Model 840/845 Contactless Smart Card Reader 1
Introduction
This manual is an installation guide for the CASI Model 840/845
Contactless Smart Card Reader. Throughout this guide, the abbreviation
84x will stand for reader Models 840 and 845.
The 84x Reader is designed to mount on a standard U.S. single electrical
gang box.
The Model 845 is identical to the Model 840 except for a built-in twelve
position keypad. This feature makes this reader ideal for installations
requiring keypad PIN entry in addition to a valid smart card read.

Installation Steps
The following is the general sequence of steps to follow in installing the
84x Reader. Each step is explained in further detail in the sections that
follow.
1. Mount the reader backplate only (the reader will be mounted later).
Refer to “Mounting the Reader” below.
2. Connect the reader. Refer to “Connecting the Reader” on page 6.
3. Mount the reader to the backplate. Refer to “Mounting the Reader”
below.
4. Test the reader. Refer to “Testing the Reader” on page 22.
5. If necessary, refer to “Troubleshooting Guide” on page 23 for
troubleshooting information.
Mounting the Reader
The reader comes with a backplate suitable for mounting directly onto a
standard U.S. electrical single-gang box. The reader may also be mounted
directly onto a hollow wall. The reader is supplied with a weather-
resistant gasket.
The figures listed below begin on the next page. Refer to the appropriate
figure for the type of reader you are mounting.
Figure 1, “Model 84x Reader - Gang Box Mounting,” on page 4.
Figure 2, “Model 84x Reader - Wall Mounting,” on page 5.

Connecting the Reader
Cabling Distances
The table below gives the maximum cabling distances between the reader
and the microcontroller.
NOTES:
1. Reader supply voltage measured at microcontroller: 13.6V is nominal
when line-powered; 12V is nominal when battery-powered.
2. All cable distances are typical maximums.
3. Readers powered by a local 12VDC power supply will have a maximum
cable distance of 500 feet (152m) of 24 AWG telephone wire.
4. The reader will wor well with unshielded cable in most environments.
No company can guarantee that data will be reliably transmitted for long
distances on unshielded cable in every installation. Typical Wiegand
reader installation requires eight-conductor shielded cable to provide
reader power, controller communication, door contact, exit push
button, and tamper switch status. The same functionality is provided by
Proximity Perfect readers, "supervised" with four-conductor unshielded
cable.

Communications Settings
Testing for Current Settings
Perform the following steps to test for current settings:
NOTE: RS-232 mode for Revision B printed circuit boards and higher.
1. Remove power from the reader.
2. Place a mini-jump over both pins of JP4.
3. Add power to the reader and listen for the number of beeps.
NOTE: The number of beeps indicate the current communications mode
set.
• 1 beep = Supervised F/2F
• 2 beeps = Unsupervised F/2F
• 3 beeps = Strobe
• 4 beeps = Wiegand 4001
• 5 beeps = RS-232
4. Remove power from the reader.
5. Place a mini-jump over one (1) pin of JP4.
6. Add power to the reader and resume normal operations.

Setting the Communications Mode
(CASI Mode)
In CASI mode, the reader splits the serial number into two parts for
Wiegand formatting. The other communication modes return the number
resulting from this split format. In this manner, all five output formats
yield the same number to the system. This number will not match the
serial number provided by the card manufacturer.
The following steps are for setting the communications mode in
CASI mode.
NOTE: RS-232 mode for Revision B printed circuit boards and higher.
1. Remove power from the reader.
2. Place a mini-jump over both pins of JP4; JP3 is open.
3. Add power to the reader and listen for the number of beeps.
NOTE: The number of beeps indicate current communications mode
set.
• 1 beep = Supervised F/2F
• 2 beeps = Unsupervised F/2F
• 3 beeps = Strobe
• 4 beeps = Wiegand 4001
• 5 beeps = RS-232
4. Push and release the tamper switch the number of times that
correspond to the communications mode desired.
NOTE: If you exceed the number of pushed listed below, an error
response will sound and flash. Simply repeat this step.
Modes:
• 1 push = Supervised F/2F
• 2 pushes = Unsupervised F/2F
•3pushes=Strobe
• 4 pushes = Wiegand 4001
• 5 pushes = RS-232
5. Wait 5 seconds and then remove power from the reader.

6. Place a mini-jump over one (1) pin of JP4; JP3 remains open.
7. Add power to the reader and resume normal operations.
Setting the Communications Mode
(Native Mode)
In Native Mode, the reader uses a straight binary to BCD conversion of
the serial number to match the serial number given by the card
manufacturer.
The following steps are for setting the communications mode in Native
Mode.
NOTE: RS-232 mode for Revision B printed circuit boards and higher.
1. Remove power from the reader.
2. Place a mini-jump over both pins of JP4 and JP3.
3. Add power to the reader and listen for the number of beeps.
NOTE: The number of beeps indicate current communications mode
set.
• 1 beep = Supervised F/2F
• 2 beeps = Unsupervised F/2F
• 3 beeps = Strobe
• 4 beeps = Unused
• 5 beeps = RS-232
4. Push and release the tamper switch the number of times the
correspond to the communications mode desired.
NOTE: If you exceed the number of pushes listed below, an error
response will sound and flash. Simply repeat this step.
Modes:
• 1 push = Supervised F/2F
• 2 pushes = Unsupervised F/2F
•3pushes=Strobe
• 4 pushes = Unused
•5pushes=RS-232

5. Wait 5 seconds and then remove power from the reader.
6. Place a mini-jump over one (1) pin of JP4 and remove JP3.
7. Add power to the reader and resume normal operations.
NOTE: Mode 4 is not available in Native Mode. Beeping and flashing
LEDs indicate that Mode 4 has erroneously been set in Native Mode.

Digital Input (Door Contact and Exit
Request) Supervised F/2F Mode Only
The door contact (alarm) and exit request are both configured for 4-state
reporting. If used, then end-of-line resistors (two at 1,000 ohms each) are
required.
1. Install the door contact and the two end-of-line resistors
(installer-supplied) at the contact.
2. Wire the door contact/end-of-line resistors to pin JP2-8 and pin JP2-9.
3. Install the exit request contact and the two end-of-line resistors
(installer-supplied) at the contact.
4. Wire the exit request/end-of-line resistors to pin JP2-10 and
pin JP2-11.

NOTES (Unless otherwise specified): 1. A 470-ohm, 1/2W, pull-up resistor is required between +12VDC and READER DATA 1. The pull-up resistor should be
installed at the microcontroller’s terminal bloc . A resistor is supplied with the reader. MicroProx does not require this resistor.
2. Shielded cable is recommended in electrically noisy environments. 3. If using shielded cable, connect all shields together at the micro end. Connect to ground stud in the lower left corner
of Micro/5 cabinets using 14 AWG wire. No shield connections at the reader.
4. If using a local power supply, do not connect +12V line from the microcontroller to the reader. However, the negative
side of the power supply must be connected to the micro (pin 2 on the reader port). Keep the wiring from power supply to reader less than 50 feet.
5. Refer to the appropriate system manual to determine whether this connection is required for door switch operation. 6. Bloc ing diodes may be 1N4148 or similar (installer supplied) and located in a secured area. 7. Protection diodes may be 1N4002, 1N4003, or 1N4004 (installer supplied) for the door stri e assembly. 8. Fuse, power supply, door stri e, and relay are provided by the installer.
