AN INTRODUCTION TO MR 100
The Symbol RF Receiver Module or MR 100 is a single port, lightweight reader designed for easy integration with RFID
printers, handhelds and applicators1. This chapter describes some of the important features of MR 100.
2.1. MR 100 Features
2.1.1. Designed for Embedded Applications
The Symbol MR 100 offers a simplified design and better utilization of board space, which results in a small and
lightweight device that can be used very effectively in embedded systems.
2.1.2. Robustness
The MR 100 Reader is highly robust and can be used in environment with extreme temperatures and humidity. It is
capable of functioning from temperatures ranging from –20DC to +60DC and 5% to 95% humidity.
2.1.3. Performance
The MR 100 uses a Symbol patented interrogation protocol, which makes it capable of Read rates of up to 200 tags per
second. The same protocol also enabled it to work in noisy environments.
The MR 100 has a read range of up to of 10+ feet, and a write range of up to 4+ feet. The range however, depends on
factors like Antenna Gain, interference and traffic.
2.1.4. Support for Industry Standards
The MR 100 provides all RF and control functions that are required for powering and communicating with industry
standard UHF passive tags. It has capabilities of interacting with both Class 0(Read Only) and Class 0 (Read Write) tags
2.2. What’s shipped
The customer has multiple options to choose from while purchasing the MR100.
Host Interface Æthe JST 14-Pin Connector can be used to connect the MR 100 to devices. the customer can
choose between RS 232 (serial) or TTL interface depending on the device to which the MR 100 will be
connected to.
Antenna Port Ædepending on, what the MR 100 needs to be deployed for, the customer has an option of
purchasing the single antenna port version (which uses the same antenna for both transmissing and receiving)
or dual port (which allows the use of separate antenna for transmitting and a separate antenna for receiving).
1With appropriate regulatory certifications

2.4. Basic Connections
Connecting the MR 100 to your system is fairly easy and includes a simple two step process:
Connect the MR 100 to the device you plan to use with the reader using the JST 14-Pin Connector. Depending
on the device you wish to connect to you should select between the RS 232 / TTL interfaces before ordering
your MR 100.
Connect the MR 100 antenna port to your antenna: If you are using a MR 100 with a dual antenna port
connect one to a transmitting and 1 to a receiving antenna. If you are using a MR 100 with a single antenna
port connect the antenna port to the antenna – in this case the single antenna acts as a transmitting and
receiving antenna. Your choice of antenna will vary depending upon the read write distance that you want with
your MR-100. e.g. For a typical read range of 10’ and a write range of 4’ an antenna of 6dBi gain must be
selected.

Chapter 3.
BYTE STREAM PROTOCOL WITH MR 100
This chapter gives a brief introduction to Byte Stream Protocol and how it can be used to communicate with the MR
100 reader. If you are looking for more details of Byte Stream Protocol and how it can be used with other Symbol
Readers refer to Matrics API Programmers Manual.
3.1. Byte Stream and MR 100
Byte stream protocol can be used to send data to the host using a 2 wire serial link (RS-232) or TTL as factory option at
the following Baud Rates:
19200
38400
57600
115200
3.2. Generalized Request and Response Packets described
The byte stream packet follows generalized packet format for request and response packet. This section describes the
packet format which most request and response examples in this document will use. In practical implementation, most
of the times, these packets are arrays of bytes where elements are arranged as per specified format.
A general request packet that is being sent to MR 100 over host interface must be formatted as follows:
Field Number of Bytes
(Size) Value Description
SOF 1 0x01 Start Of Frame
Node Address 1 0~0x1F i.e. 0 to 31. Node address that had been set on the reader
Packet Length 1 See Description Size of the packet that is being sent. This should not
include the size of SOF but should include the size of CRC.
Command 1 See Description Each Reader API Command corresponds to a number. This
number tells the reader which command to fire. Populate
this byte with the value of the command which you want
the reader to fire.
Data Variable See Description Depending upon the command you are executing you may
need to send different number of bytes formatted
differently. See the definition of the command you want
to execute for more details. A Typical Request data
packet can be 0 to 64 bytes.
CRC 2
(1 for LSB & 1 for
MSB)
Dependent Bitwise inversion of the 16-bit CCITT-CRC of the packet
excluding SOF, with the LSB (Least Significant Byte) first.

Byte Stream Protocol with MR 100 MR 100 User Manual Page: 9
MR 100 User Manual
For every request sent to the reader there may be one / more response packets that the reader sends back to the host.
A Typical Response Packet has been described in the following table:
Field Number of Bytes
(Size) Value Description
SOF 1 0x01 Described in Request Packet description.
Node Address 1 0~0x1F Described in Request Packet description.
Packet Length 1 See Description Described in Request Packet description.
Command
Mirror 1 See Description Mirror of the original command in the response packet.
Status 1 See Description The result or status of a command execution. See Status
Field Description section for more details.
Data Variable See Description In a typical response packet the size of data field may
vary from 0 – to 250 bytes. The first byte of response data
usually contains the error code if error bit of status field
has been set. For more information on error bit see Status
Field Description section. For more information on error
codes see Error Codes Described section.
CRC 2
(1 for LSB & 1 for
MSB)
Dependent Bitwise inversion of the 16-bit CCITT-CRC of the packet
excluding SOF, with the LSB (Least Significant Byte) first.
