1.1 INTRODUCTION
Datalogic Automation's passive read/write system is a complete family of field-proven
read/write Radio Frequency Identification products. The system consists of reader/writers,
antennas and controllers or bus interfaces, RF tags, and ancillary equipment. Tags can be
attached to a product or its carrier and act as an electronic identifier, job sheet, portable
database, or manifest. Tags are read and updated via a Datalogic Automation Reader/Writer
through any nonconductive material while moving or standing still.
The passive design of the Read/Write system uses the RF field from the antenna to power
the tag, eliminating the need for tag batteries. The passive read/write system is designed to
provide cost effective RFID data collection and control solutions to less demanding
automation and material handling applications.
The C827 Series Reader/Writer uses a standard limit switch type enclosure to house the
controller board. The C827 has an integrated antenna with vertical and horizontal read
orientations. The C827-03 features an 18 mm tubular remote antenna at the end of a 1 meter
cable. The C827-06 has a rectangular, 30 x 40 mm remote antenna at the end of a 1 meter
cable. The system uses the internationally recognized ISM frequency of 13.56 MHz to both
power the tag, and to establish a radio link to transfer the information.
The C827 Reader/ Writer is a stand alone unit that communicates to the host over an RS232
point-to-point interface. The C827 standard application program supports the well
established ABx protocol and includes all the command functions for efficient serial and RFID
communications.
1.2 UNPACKING AND INSPECTION
Unpack the Reader/Writer and save the original shipping carton and packing material in case
any item has to be returned to Datalogic Automation. Inspect each item carefully for evidence
of damage. If any item appears to be damaged, notify your Datalogic Automation
representative immediately.
Check that all of the following items are present:

2.2 C827 ANTENNA DIRECTION
The C827 Reader/Writer with integrated read head, has two possible antenna orientations;
emitting from the face (horizontal) or emitting from the top (vertical). Your unit is set by the
factory to be emitting from the horizontal location. To change the read head to vertical
emitting you must remove the head and change a jumper position.
2.2.1 Changing the C827 read head orientation
CAUTION: The following procedure exposes sensitive components to possible damage due
to electrostatic discharge (ESD). Disconnect all power from the unit and take proper
grounding precautions to eliminate potential ESD.
Begin by unfastening the four captive screws holding the read head to the controller block
(see Figure 2-6).

2.2.2 Mounting the C827
The range of the Datalogic Automation Reader/Writers is affected by electromagnetic
radiation and metal. Mount the reader/writer to minimize the impact of these factors. The RF
field of the reader/writer can also cause errors when reader/writers are spaced too closely
together. Do not position adjacent antennas closer than 6 inches center to center.
The remote antennas for the C827-03, C827-06, have a cable length of 1 meter. The tubular
antenna should be mounted through non-ferrous materials. Surrounding the antenna with
metal will greatly reduce the reading range of the antenna. If mounted in metal, ensure that
the face of the antenna extends at least 1 inch (25 mm) beyond any metal surface.
NOTE: This device and its antenna are intended for indoor use only.
2.2.3 Guidelines
Isolate the reader/writer and antenna from electromagnetic radiation.
Avoid surrounding reader/writer and remote antenna with metal.
Maintain at least 6 inches (50 cm) minimum spacing between adjacent reader/writers
or antennas.
Stay within the guaranteed range for the tag to be used.
Conform with EIA RS232 standards.
Use a non-ferrous spacer when mounting tags to metal.

2.2.4 Mounting HMS Tags to Metal
Mounting tags to metal can greatly impact the effective range of the tags. To maintain the
best possible range, the tags should be mounted away from the metal surface using a non-
ferrous spacer. Mounting kits are available from Datalogic Automation as shown in Fig.2-8
and Table 2-2 below.

3.1 TERMINAL SCREWS
Power and serial communications connections for the C827 are made at terminals screws
located on the interface block of the C827 enclosure. Your cable should be wired to these
terminals according to the pinouts given in Table 3-1 and shown in Figure 3-1.

NOTE: To fully comply with FCC regulations Part 2, you should attach a ferrite clamp (such a
WURTH 7427144) around the power and communication cables as close to the cord grip as
possible.
CAUTION: Do not bundle communications wiring with high current power lines. This will
cause communications errors.

3.1.1 Power Requirements
The device is intended to be supplied by a UL Listed or CSA certified power unit with “class2”
or LPS power source.
3.2 WIRING
To connect your cable to the C827 Interface Block:
1. Remove the head with attached antenna by loosening the four captive screws.
2. Loosen the two captive screws in the interface block and separate the two parts as
shown in Figure 3-2.
3. Loosen the cord grip, feed the cable through the cord grip and attach the wires to the
terminal screws shown in Figure 3-1. Tighten the cord grip to seal the cable. Note that
you must use a cable of sufficient diameter to properly seal with the cord grip. The
recommended minimum O.D. is .125 inches (3.2 mm).
4. Re-assemble the enclosure and secure the screws.

4.1 OVERVIEW
The C827 offers RS232 communications. Normally, the RS232 interface is used to program
and test the device but can also be used as a point-to-point serial connection.
Communications parameters are set by DIP switches located inside the reader/writer or by
the configuration program accessed over the RS232 port.
CAUTION:
Do not bundle communications wiring with high current power lines. This will cause
communications errors.
4.2 RS232 INTERFACE
The C827 is set by the factory to initially communicate via RS232, during the first four
seconds after power-on the device will respond to commands from the RS232 lines. If no
commands are received by the reader/writer during the five seconds, the reader/writer will
continue according to the position of DIP switches. For more information on the Configuration
Menu refer to Chapter 5.
To communicate with the device via RS232, set the serial communications parameters of the
host as follows:
Baud rate 9600
Parity none
Data bits 8
Stop bit 1
NOTE: The reader/writer automatically resets to 9600, N, 8,1 for five seconds whenever the
power is cycled, after which it will apply the setting made in the configuration menu.

4.3 RS232 SERIAL CONNECTIONS
The connections for the RS232 interface are RS232 TX (data from the C827), RS232 RX
(data to the C827), and Ground or Signal GND it depends on selected Isolated/not isolated
connection type.
The signals and electrical loads from the RS232 TX and RS232 RX pins should conform to
the electrical specifications of EIA Standard RS232. The maximum cable length specified
under this standard is 15m. (50 feet). High quality shielded cable should be used for these
connections.
Table 4-1 gives the connections required to establish RS232 communications between the
reader/writer and an RS232 host.

4.4 DIP SWITCHES
There are eight DIP switches inside the C827 enclosure that control the bus address of the
device, the speed of the bus communications and whether RS232 or RS485/SUBNET16
communications are active. To manually set these parameters you must open the reader/
writer to expose the DIP switches.
To expose the DIP switches, disconnect the reader/writer from power and remove the two
captive screws holding the cover to connector backplate. The DIP switches are located at the
bottom of the device.
All DIP switches are set to the OFF position at the factory.
While all switches are in the OFF position, changes made through the configuration program
will be effective. Changing any of the switches to the ON position will override settings made
through the configuration program for those variables. Some RS232 variables (baud rate) not
set by the DIP switches can still be modified by the configuration program. See Chapter 5,
page 26, for more information on the configuration program and serial variables.
Figure 4-1 shows the DIP switches and the OFF/ON positions.
The C827 is shipped with all the switches set to the OFF position.
Figure 4-1: DIP switch positions
Table 4-3 describes the function of each switch.

* NOTE: The C827 special version SH4352 is only a custom product with the reader block. This
product does not include the terminal block and the antenna head. This product has been
developed exclusively to work with the HMS827 antenna head with 2 connectors version.
