HF Multi ISO RFID Reader User Manual, Firmware V1.2.5 1508-USM-00-0-05
Scope
The HID HF Multi ISO Reader Module supports a broad range of tags compliant with ISO 14443
type A and B standards, including SR176 tags, tags which belong to the NXP MIFARE family, ISO
15693 tags, ISO 18000-3, EPC and UID tags. An open command structure allows the device to
communicate with tags that use an operating system. The read/write unit supports ISO 14443-4
layer with automatic chaining, 256 byte buffer and frame length, extended time framing and up to
848kBaud transmission rates over the air interface.
Several protocols are available to enable the reader module to be connected to a variety of
equipment. The ASCII protocol facilitates the use of a simple terminal; the Binary protocol provides
robust communication more suitable for a dedicated host system. If a host computer is used, then a
function library is available, providing function calls rather than low-level ‘byte-bashing’.
For the SAM interface security features and DESFire credential DES encryption, the function library
provides access to these features in the Reader Module. The function library is available for
Windows CE and XP host applications.
Major applications are:
Access control, identification using security credentials
Ticketing using standard MIFARE and DESFire credentials

3TTL buffer output / input. If user port is used as an output, a 1kΩ(current limiting) series resistor
has to be integrated into the connecting wire, otherwise the reader device can be damaged.
4Voltage spikes below GND at the MCLR/VDD pin, including currents greater than 80mA, may
cause latch-up. Thus, a series resistor of 50-100should be used when applying a "low" level to
the MCLR/VDD, rather than pulling this pin directly to GND.

If the supply voltage and any noise modulated on the supply voltage remains within the specified
limits, no further filtering is required. In some cases it is recommended to use additional filtering for
the power supply line. Insufficient power line filtering could cause unexpected or irregular
performance drops.

1.4.3 Serial Interface
The OEM Board can be connected directly with a micro controller. Alternatively the OEM Board also
can be connected to most serial interface types by using the right interface converter circuit. In
order to optimize the communication quality the specific application note of the interface converter
circuit needs to be taken into consideration.

1.4.5 SAM Connector/Socket
Note: The power supply to the SAM must be turned off during the entire SAM insertion/withdrawal
period; otherwise damage to the SAM may occur.
When using a SAM with the OEM board, it is recommended that a 100nF decoupling capacitor be
fitted between Vcc and GND close to the SAM socket to ensure proper operation. The complete
circuit diagram is shown in Figure 8 - SAM Connector.

2Software
In order to offer the widest possible choice of interface, the MultiISO reader offers both ASCII and
Binary serial protocols – see Transmission Protocol, page 19.
EEPROM registers in the reader hold default settings for Station ID, protocol, serial and air-speed
settings, timing parameters and modulation index – listed in Register Set, page 22. These registers
are alterable using the Read/Write EEPROM commands detailed in Command Set page 34. The
register settings are applied to the reader through the configuration registers.
These configuration registers may be altered ‘on-the-fly’ to immediately affect performance by the
‘set configuration flag/register’ commands, but the changes are lost once the reader is powered
down, unless also written into the EEPROM registers. These and all other configurable settings are
detailed in the Register Set – Register Set, page 22.
General reader commands are listed in Command Set page 34 and detailed in Common Command
Details, page 36, dealing with the physical attributes of the reader – reset, LED control, User port
control, Antenna power – and the basic tag commands – include/exclude tag types, continuous
read, tag select and air speed select, and simple block read/write commands.
Tag-specific commands for MIFARE and My-D tags are listed in Sections ISO 14443 Type A
(MIFARE®) only commands, page 64 and my-d™ secure, page 77, and commands to manipulate
keys are listed in Key Management, page 69.
For more complex commands, the ‘t’ command is used. This uses a data frame or packet to
exchange information – see ‘t’ Command – Data Frame Transfer, page 83 and ‘t’ command block
format & examples, page 87 for examples of use
To communicate with the optional SAM, the ‘e’ command is used. This also encapsulates a data
frame/packet to exchange information, based on the ISO7816 APDU – see ‘e’ command – SAM
data frame transfer, page 90 and ‘e’ command block, page 95 for examples of use.
2.1 Transmission Protocol
Two protocol modes are supported, with the default held in the reader EEPROM. As factory default,
the ASCII protocol is used, and the default serial configuration is 9600baud, n, 8, 1, with no
handshaking.
2.1.1 ASCII Protocol
This protocol is designed for easy handling. The commands may be issued using a terminal
program, such as HyperTerminal, and the data is transmitted as ASCII hexadecimal that can be
easily displayed on the terminal program.

2.1.2 Binary Protocol
This protocol is designed for industrial applications with synchronization and frame checking. An
addressing byte for party line (master/slave, multi-drop) is also included.
The protocol usually requires a device driver. Data is transmitted in binary mode. The reader uses
an internal binary watchdog timer to ensure correct framing.
STX Station ID Length Data BCC ETX
1 byte 1 byte 1 byte Variable length 1 byte 1 byte
The binary frame version 2 is only sent to the host. It is implemented to give extended information to
the host. Version 2 must be enabled in the Protocol configuration 2 register.
STX Station ID Length Flags Data BCC ETX
1 byte 1 byte 1 byte 1 byte Variable length 1 byte 1 byte
2.1.2.1 STX
Start of transmission (02h for data block sizes 1-256 bytes, 82h for data block sizes 257-512 bytes).
2.1.2.2 Station ID
Unique ID of the station
00h: Reserved for the bus master. Readers send response to this device ID.
FFh: Broadcast message. All devices will execute the command and send their response.
2.1.2.3 Length
Length defines the length of the data block (including the flag byte if binary protocol version 2 is
activated). If the STX character is 02h, the length field represents the actual data block length (1 to
256, with a length of 256 being represented by the value 0). If the STX character is 82h, the length
field should be added to 256 to obtain the block length (for example, 1 = data block length of 256+1,
2 = data block length of 256+2, 0 = data block length of 256+256).
2.1.2.4 Flags
The flag byte gives additional information to the host.
