Introduction This document is intended to assist technical service personnel engaged in the installation of the SAMSys MP9320 UHF Long-Range Reader. The document includes procedures for installing and configuring the reader to meet local standards and regulatory requirements.
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. Four-antenna configurations are used for portals and loading dock doorways. Caution For uncontrolled environments (in the general population), the spacing between the antenna(s) and any persons must be at least 9 inches when the reader is operating at full power (4 Watts EIRP).
The MP9320 is factory calibrated for operation with the following type of antenna: Antenna Parameter FCC ETSI Frequency 902-928 MHz 865-870 MHz Polarization Circular Circular Gain, dBic 8, max 5, max Antenna power handling 1 W, minimum 1 W, minimum VSWR, maximum 1.3:1 1.
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 2, the reader is designed for horizontal or vertical installation. Mounting keyholes are provided on each side of the base plate for easy, nonpermanent, installation and removal. Caution To ensure proper cooling of the reader, verify that the fan intakes and vents are free of obstructions.
Figure 3–MP9320 Base Plate with Mounting Keyholes Hollow Concrete Block Wall Mounting To temporarily mount the MP9320 to a hollow concrete block wall, SAMSys recommends metal sleeve type concrete anchors that accept a #10 screw and flat washer. To install the MP9320 on a hollow concrete block wall, perform the following. 8 1. Refer to Figure 3, and mark the location of the mounting screws. Do not install the anchors into the mortar joint. 2.
Solid Concrete Wall Mounting To temporarily mount the MP9320 to a solid concrete wall, SAMSys recommends one-piece expansion type concrete anchors that accept a #10 screw and flat washer. To install the MP9320 on a solid concrete wall, perform the following. 1. Refer to Figure 3, and mark the location of the mounting screws. 2. Drill the appropriate size hole for a expansion type anchor. 3. Install the anchors 4. Install the washers and insert the screws. 5. Tighten the screws to within .
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 4–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.
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.
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 5). Refer to the Specifications chapter for detailed information on the RS-485, Power, and Digital I/O Port.
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.
Digital (TTL) Input/Output Setup The MP9320 is equipped with a digital I/O port that provides four input signals and four output signals. Refer to the SAMSys Forth Programming Language Reference Guide for programming information. Digital I/O Overview As shown in Figure 6, the inputs are optically isolated. The outputs are open collector. Figure 6–Digital Input and Output Port Configuration 14 Signal Name Pin No.
Setting Digital Input for Reader Duty Cycle Control MP9320 readers with software version 1.33.04 or later can be configured for limited duty cycle (trigger enabled RF output) by setting one of the digital inputs. This functionality can be enabled to meet regulatory requirements or to set the reader to respond to external events. In order for the reader to recognize the external event, the Protocol Control Word (PCW) must be configured. Perform the following to setup the reader for external trigger: 1.
Field 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. For readers with software version 1.3.1.
6. Run the forth command XMITCAL as follows (enter each line in the same way that previous CHUMP commands were entered): }cf! xmitcal quit 7. Connect an RF power meter to the antenna cable to verify power output is correct and record the power out. 8. Reconnect the antennas. The unit is calibrated for ETSI or FCC. • For FCC, power has been adjusted to 1 Watt max at the end of the cable or 4 Watt EIRP out of the antenna whichever is less.
