General Combi RFID Master MC30RG is a combined unit that can operate completely independent as an RFID Portal that is able to read RFID active tags on 125 kHz/434MHz as well as passive tags on 868/915MHz (see Appendix 1 for active and passive tags examples). After reading, the incorporated Single Board Computer (SBC) can filter the relevant readings and can report them over a wireless GSM / GPRS link to a central database for processing. The marketing name for MC30RG is LS4230 – this name is printed on the front label. Figure 1 - General view 2. MC30RG Description On the top side of the MC30RG portal there is a cover that needs to be removed in order to connect the unit to power and wired RS485 communication lines. Place the portal on a flat surface with the cover up. If the passive antennas are installed, it is recommended to place the portal transversal on a narrower work table with the top cover up such that the two passive antennas hang in the open space. Remove the plastic quarter-turn screws and lift the cover. RS485 Cover Cable Remove the four plastic screws using a coin or a flat screwdriver 10-20mm wide.

Installation Typical installation of the MC30RG is presented in Figure 6 below. The MC30RG portal requires one 18 AWG 3 wires power cable to be run to the mid point of the portal (connectors J15 or J16) from a +24V power supply. It should have an extra 3ft at each end. Two metal chains will be dropped from the ceiling, 70cm apart. The unit shall be hung from the metal chains using two S-links connected to the two existing chains attached to the exciter. The exciter weight doesn’t exceed 18Kg. A Lyngsoe technician will do the final cable connections. Figure 6 Doc no. 950237 - Page 6 of 14 Combi RFID Master MC30RG Lyngsoe Systems Figures 6 to 8 show a typical portal installation. Figure 7 Figure 8 4. MC30RG Connections Power Connection WARNING! Before you start the installation, check if the Power Supply provides the specified output voltage: + 24Vdc +/- 10%, and min. 5A for a portal in a fully equipped configuration. A universal power adapter that accepts input voltages from 100V/1.2A to 240V/0.5A is recommended. For the power connections use the 4.2mm Mini-Fit Jr receptacle (LS PN 350238) and the female crimp terminals for AWG18-24 (LS PN 350238). Strip the wire isolation 3.0-3.5 mm and crimp the terminals on the wire using the Molex crimping tool 11-01-0197. Insert the terminals in the receptacle body – terminals 1 for (+24V), terminal 3 for (GND) voltage. Remove the cover. Plug in the power connector into any of the corresponding headers J20 or J21 on the MBD40 motherboard. The POWER LED (green) goes ON, and the display shows a “spinning wheel” pattern. This pattern shows the portal is currently awaiting initialization commands from the PC and it will remain on the display until a command is received by the motherboard to change it or a configurable timeout (default 5min, see parameter HPT) has elapsed. If no command was sent from the RS485 bus master (host PC) to change the display prior to this timeout duration, the display will start to flash “FF” as a warning to the user that communication with the host has not been established yet. Wired Communication: RS485 Connections For the RS485 connection use a standard Cat5 Ethernet cable and RJ45 plug. Crimp the connector using the recommended tool and the following color scheme: pin 1 - Wh/Or; pin 2 – Or; pin 3 – Wh/Gr; pin 4 – Bl; pin 5 – Wh/Bl; pin 6 – Gr; pin 7 – Wh /Br; pin 8 – Br. Insert the RS485 incoming cable in one of the J3 or J4 connectors, and the outgoing cable in the other one. The order does not matter as the two connectors are connected in parallel. If the portal is an end unit, so if only one RS485 cable is connected to the portal, move the J5 and the J6 jumpers to the “L” (loaded) position such that the line is properly terminated.

The Display and the two buttons Display Cooling fans and vents Status LEDs Two Push Buttons The LS4230 portal includes a dual digit display and two push buttons. The display and the buttons are visible as slave devices on the RS485 bus. Some command examples are shown in chapter 5.4 “Remote Control” and are described in more details in the motherboard MBD40 Rev A user manual. The two buttons are useful in troubleshooting. After pressing one of them, two events happen. Firstly, status flags are updated in motherboard’s RAM that can be read Figure 9 remotely by querying the parameters BTT and BTS. Secondly, the “spinning wheel” sequence is shown on the display to acknowledge the press and signal that the portal is waiting for the host to process the request. The “spinning wheel” sequence will also timeout after a specified interval (default 30s, see parameter HBT) and then the display will flash “FF” again. Motion Sensor In a more powerful use scenario, the buttons and the display can be used to send test codes to the host computer. For this, the MBD40 motherboard BCM parameter needs to be set first to a value higher than “0”. Then, by pressing the “Test” button, an incrementing code from 0 up to the BCM value is displayed. When pressing on the “Send” button, the displayed code is stored in the parameter “BCD”. This code, when retrieved by the host computer, can trigger different actions like downloading remotely the data, or trigger different test programs. The specific actions are entirely dependent on the host programming (EDECS). This feature may be useful during the entire life cycle from the production process, installation and maintenance of the portals. 5.2. The Motion Sensor The motion sensor is a Passive Infrared Receiver and responds to body heat so it tracks people’s movement. Its sensitivity window has been adjusted to match the active reading area of the portal. It can be remotely enabled or disabled by setting the EMS parameter. 5.3. The front panel LEDs The portal also includes two LEDs. The GREEN LED labeled “Power” is ON all the time as long as the portal has power. The RED LED labeled “Field” indicates the portal readiness to read active or passive tags. Its meaning depends on the portal configuration and settings. There are three main scenarios. A) In the simplest scenario, the Field LED is ON all the time and the LF Exciter and Passive Reader are ON all the time, if equipped. B) In the next scenario, the motion sensor is enabled. Whenever a motion is detected, the Field LED is turned ON and an enabling signal is sent to the LF exciter and the Passive reader. They in turn start reading the active and Doc no. 950237 - Page 8 of 14 Combi RFID Master MC30RG Lyngsoe Systems passive tags in range. Few seconds after the motion stops, everything turns OFF. This delay after the motion stops is 5s + the value of the EMD parameter (which is set by default to 0s). C) In the most complex scenario, the “Field” LED does not immediately indicate that an enabling command was sent to the LF and / or the passive tags reader. It will actually wait first for a confirmation signal from the installed transmitters that they are actively started reading tags, and only then it will turn ON. This provides for an extra level of confidence and feedback for the user. For example, if something is defective and the LF field level is significantly below the programmed level, the “Field” LED will blink intermittently instead of steady red. The table below indicates the possible combinations depending on the parameters PEX, PPS and PFB. For more details, please refer to the MBD40 Rev A user manual: Field LED Truth Table: PEX PPS PFB Always ON On when exciter provides valid feedback On when triggered by motion sensor, no feedback is expected nor required On when passive reader provides feedback On when exciter provides feedback & triggered by motion sensor On when exciter and passive reader both provide feedback signals 5.4. Field LED Operation The operation of the MC30RG is controlled by commands and parameters. The parameters values are set into MC30RG during the configuration session. This configuration is controlled by a PC running a serial communication program like ProComm or HyperTerminal, through a serial communication link type RS485. There are several specific commands to configure or to query the MC30RG parameters values. Each module inside MC30RG has a unique address called NetId. It is strongly recommended to set the same NetId for all the modules inside a portal, although this is not necessarily required. The NetId is an integer in the range 0 to 127 and is a good practice to clearly mark it on the front label in the designated area. By default all Lyngsoe modules installed in an MC30XX portal have NetId = 1. The Lyngsoe modules inside the portal can be controlled by sending commands that follow this general syntax:where is a single character that is specific for each module type. 5.5. Commands Examples Some typical commands are listed below, showing the command sent from the PC in RED underlined and the replies in BLUE (replies may vary depending on the firmware versions): Doc no. 950237 - Page 9 of 14 Combi RFID Master MC30RG Lyngsoe Systems 5.5.1.
