Introduction About the MP9320 The MP9320 is one of the most advanced UHF long-range readers in the industry. This multi-protocol device currently supports many of today’s most popular UHF tags. The MP9320 recognizes multiple protocols simultaneously during operation. With full-duplex capability, the device can read or write to any tag, depending on the tag capabilities.
MP9320 User’s Guide Figure 2–SAMSys Reader Network In addition to the scalable, multi-protocol architecture, the MP9320 includes the following features: 4 • LED indicators • (4) antenna ports • Multiple interface connection options (RS-232, RS-485) • Digital input and output lines • Integrated real-time clock with battery backup (optional) • On-board temperature sensor (optional)
Introduction Physical Description NOTE: The reader enclosure is designed for office, indoor warehouse, and light manufacturing areas. If a sealed reader is required for wet or hazardous environments, contact your SAMSys representative. The digital board contains four LED indicators to provide the operational status of the reader. The LEDs are visible on the front panel of the reader.
MP9320 User’s Guide In addition to the operational status LEDs, four Active Antenna LEDs provide indication that RF power is being applied to one of the four antennas. Figure 4–MP9320 Active Antenna LED Indicators Four SMA type antenna ports are provided on the end panel. The reader also has two power and communication interface connectors on the opposite end panel.
Chapter 2 Installation This chapter provides information for installing the MP9320.
MP9320 User’s Guide Antenna Installation The MP9320 supports from one to four external antennas in a variety of configurations. One- and two-antenna configurations are typical for most conveyor and container tracking. Fourantenna configurations are used for portals and loading dock doorways.
Installation The MP9320 is factory calibrated for operation with the following type of antenna and cable: Antenna Parameter FCC ETSI Frequency 902-928 MHz 865-870 MHz Polarization Circular Circular Gain, dBic 8, max 8, max Power, minimum 1W 1W VSWR, maximum 1.5:1 1.5:1 Cable Parameter Value Type RG58C/U Length 2 Meters Connector SMA type plug, reader side It is highly recommended that the antenna mounting be adjustable in order to obtain the best performance from the system.
MP9320 User’s Guide 4. Mount each antenna and install the mounting screws. Do not overtighten the screws. Damage to the antenna case may result. 5. Route each antenna cable back to the reader location. For dual-opposing or portal configurations, route the opposing cables so they can not be damaged by equipment or personnel. 6. Secure each antenna cable with wire ties or other restraint.
Installation Reader Mechanical Installation The MP9320 is designed for easy installation. The following instructions provide the information to install your UHF reader. As shown in Figure 7, the reader is designed for horizontal or vertical installation. Mounting keyholes are provided on each side of the base plate for easy, non-permanent, installation and removal. Caution To ensure proper cooling of the reader, verify that the fan intakes and vents are free of obstructions.
MP9320 User’s Guide For horizontal or table table mounting, ensure the reader and all cabling is secured to the surface or frame. For non-permanent vertical or wall mounting, install the appropriate wall anchors (drywall, wood, or concrete) to secure the reader. Keyhole slots are provided for easy installation and removal. Refer to Figure 8 for the location of the keyholes.
Installation Standalone Reader Communication Setup The reader is equipped with a 9-pin RS-232 communication port for communication directly with a PC or other serial device. Refer to the Specifications chapter for information on the port. Figure 9–MP9320 Standalone RS-232 Communication Setup NOTE: A serial port adapter may be required if the device has a different connector type. For example, some PCs may have 25-pin serial connectors.
MP9320 User’s Guide Standalone Reader Verification Every effort has been made to ensure the MP9320 is configured to match your application. However, it is recommended that the reader configuration be verified before placing the reader into service. If the system is to be used as a local, standalone reader connected to a terminal or PC, perform the following: 1. Verify all antennas, cabling and power supplies are secure. 2. Verify the operator terminal or PC is connected to the reader and operational. 3.
Installation Networked Reader Communication Setup The MP9320 can be networked with other readers and to the SAMSys Interrogator Control and Concentrator Module (ICCM) using an RS-485 interface (see Figure 10). Refer to the Specifications chapter for detailed information on the RS-485, Power, and Digital I/O Port.
MP9320 User’s Guide Networked Reader Verification Similar to standalone reader verification, networked readers should also be verified before entering service. If the system is an RS-485 networked configuration using the ICCM, perform the following: 1. Verify all antennas, cabling and power supplies are secure. 2. Verify the ICCM is connected to the RS-485 network and operational. 3. Power up the readers. 4.
Installation Digital (TTL) Input/Output Setup The MP9320 is equipped with a digital I/O port that provides four logic-level (TTL) input signals and four output signals. This port can be programmed for specific applications. Refer to the SAMSys Forth Programming Language Reference Guide for more information. As shown in Figure 11, the digital inputs are optically isolated. The outputs are open collector. Figure 11–Digital Input and Output Port Configuration Signal Name Pin No.
MP9320 User’s Guide Transmit Power Calibration The MP9320 can be operated with a variety of commercially available antennas and coaxial cables. As a result, the output RF power of the reader must be configured to optimize the read range for a given antenna configuration, while not violating FCC or CE regulations. Calibration of the reader transmit RF power must only be performed by SAMSys authorized installation personnel or certified resellers.
Chapter 3 Operation This chapter provides general information to operate the MP9320.
MP9320 User’s Guide Reader Power Up When the power supply is connected, the reader starts an internal initialization sequence. This sequence momentarily lights the LEDs as follows: 1. Transmit on 2. Sense on 3. Power on 4. Fault on 5. All four on 6. Beeper on If the Fault LED flashes on at the beginning of the sequence, the reader has detected a software load fault. Restart the reader to clear the fault. Figure 12– LED Startup Sequence The reader is operational when the Power LED remains on.
Operation After the startup sequence, the RF multiplexer in the MP9320, alternately provides RF power to each of the four antennas. The Active Antenna LEDs indicate which antenna is transmitting. Figure 14– Active Antenna LED Indicators - Antenna 2 Transmitting NOTE: The number of antennas and the antenna transmit sequence is user configurable depending on the application. Refer to Appendix A for more information on reader configuration.
MP9320 User’s Guide Reading Tags When the reader completes the intialization sequence, the reader activates the RF field and, depending on the configuration, begins transmitting read detect (Rd) commands at the specified frequency. When a tag is placed within range, the reader activates the tag and reads the data. The Sense LED flashes and the beeper sounds when the tag is successfully read.
Operation Operation with the ICCM The Interrogator Control and Concentrator Module (ICCM) provides greater flexibility for accessing, configuring, and manage SAMSys readers. With the ICCM, you can access your RFID data with your own client/server applications, perform administrative functions from an easy-to-use Web interface, and remotely perform debug activities on your readers. The ICCM also has a 1/4 VGA touch screen LCD.
