About the MP9311
The MP9311 is an integral UHF RFID module designed for use in transponder
printer/programmers and other tag manufacturing equipment. This compact, low-
power module is capable of operating at 902 to 928 MHz for the North American
version and 865 to 869 MHz for the World Version.
The MP9311 module is capable of operating with active or passive tags while
transmitting a modulated signal. The system receiver has input bandwidths that
match the hopping channel bandwidths of the corresponding transmitters and
shifts frequencies in synchronization with the transmitted signal.
The MP9311 currently supports the following UHF protocols:
• EPC Class 1, Generation 2
• EPC Class 1
• EPC Class 0 including Impinj 0+ and Matrics 0+
• ISO 18000-6A and -6B
• IEM Marin 4022, 4222, and 4223
• Intermec Intellitag
• Philips UCODE EPC 1.19
In addition to multi-protocol architecture, the MP9311 includes an RS-232/TTL
Serial Port and digital input/output lines.

Connecting Power to the MP9311
On the MP9311, all power inputs are tied together and all commons (grounds) are
tied together. To connect power to the reader, apply 5 Vdc to all SCON1 power
input pin (16,18,20) and connect ground to all SCON1 common pin
(3,10,12,14,17,19). The SCON1 connector is rated to withstand a maximum
current of 1.0A per pin. Therefore, it is important that all power and ground pins be
connected to prevent reader damage. See Figure 4.

Connecting an RS-232/TTL Serial Link to the MP9311
On the MP9311, RS-232/TTL signals are located on pins 13 (TXD) and 15 (RXD).

Connecting the Digital Input and Output Lines
The MP9311 is equipped with two logic-level input signals (DIN0/DIN1) and two open-
collector output signals (DOUT0/DOUT1). To activate the digital inputs apply a
minimum 3.0 Volt differential across the DINn+ and DINn-. The outputs require a 4.7K
Ohm pull-up to 5V. See Figure 7 for typical input and output circuits.
Refer to the SAMSys Forth Programming Language Reference Guide for programming
information.To set up the I/Os to trigger tag reading and indicated tag sensing, refer to the
CHUMP Reference Guide and the Protocol Configuration Word (PCW) register.

Reader Mechanical Installation
The MP9311 is designed for installation within an enclosure. The housing is
provided with four M4 clearance through-holes for module mounting. The reader
dimensions are shown in Figure 8.
Caution Prior to mounting the reader in an enclosure, you must evaluate the operating conditions
and resulting thermal profile. When operated at maximum RF power and input supply
voltage, the MP9311 can dissipate as much as 11W of power. As a result, any enclosure
design must dissipate the generated thermal energy and maintain the internal reader
temperature below +85 degrees C. Mounting the bottom surface of the reader in direct
contact with a metal plate will provide the most efficient method of dissipating heat.

Low-Power UHF Antenna Installation
The MP9311 is designed to operate with the SAMSys Label Printer Antenna. This
antenna has an expected read range of 1-12 inches and only requires a power
output of approximately 17 dBm for optimal performance.
Figure 9–Low-Power UHF Antennas
As shown in Figure 10, mounting slots/cutouts are provided. Do not attempt to drill new
mounting holes in the antenna.
Figure 10–Label Programmer Antenna Dimensions
Caution To prevent reader damage, the RF port must be properly terminated with a 50 Ohm load
or a functional UHF RFID antenna before power up. Never power up the reader unless the
loads or antennas are connected. Always power down the reader before removing an
antenna or load from an RF port.
FCC Radiation Exposure Statement
The antennas used for this transmitter must be installed to provide a separation distance
of at least 20 cm from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter.

Installing the RF Command Suite Application
The SAMSys RF Command Suite is a Microsoft Windows application that
provides a Graphical User Interface (GUI) for SAMSys RFID Reader Products.
The application allows you to easily view tag data, configure the reader, and perform other
tag data functions. In addition, the RF Command Suite is the preferred method for sending
CHUMP commands to a reader. The RF Command Suite application is provided on the
CD shipped with your reader and can be installed on a personal computer. To install RF
Command Suite, refer to Chapter 1 - Introduction in the RF Command Suite User’s Guide.

Setting Transmit Power - TD0
Output power on the MP9311 is set by configuring the Transmit Power (TD0) register.
The output power is entered in tenths (1/10) of dBm with steps of 1/10 dBm. All
values are in decimal. For example, entering a value of 121 equates to 12.1 dBm.
For example, to set the MP9311 output power to 17.5 dBm, issue the following
CHUMP command to the reader:
}Cw,d:TD0,b:175!
The valid range of values for TD0 is from 0 (0 dBm) to 280 (28 dBm).
Setting Antenna Gain - TG0 (MP9311-Wxx only)
In order to comply with ERP and threshold limits according to EN 302 208,
MP9311-Wxx models must be configured with the proper antenna gain. Antenna gain
is set by the TG0 register. Before operation, you must determine the actual antenna
gain used in the installation, GA.
To program the TG0 register, issue the following CHUMP command to the reader:
}Cw,d:TG0,b:xxx,f:1!
Where:
xxx is computed as follows: xxx = (GA(db) + 13.0) * 10
The range of allowable xxx is 000 through 230 which gives an allowable antenna gain
range of -13dB to +10dB. Proper LBT operation according to EN 302 208 is not
guaranteed with antennas outside of this range.
