Lyngsoe Systems Exciter EX23G Exciter EX23G User’s Guide Revision C – July 21, 2006 950115B.pdf Page 1 of 7 Lyngsoe Systems Exciter EX23G 1. General Exciter EX23G is designed to operate either as a stand alone exciter or as a unit in a multi-drop asynchronous network (RS485). When it’s connected to a network it shall be programmed with an unique address (NetId). Exciter EX23G provides the following main functions: -Remote control/configuration using a RS485 communication network; -Rotating LF excitation field, using a dual loop antenna system; -LF excitation field generation controlled optionally by a motion sensor -Wireless supervision, using 434MHz UHF channel; -Optical signalization 2. Installation This chapter explains how to power up and interconnect the Exciter EX23G. Typical installation of the Exciter EX23G is presented in the figure 2-1 and the connector location in figure 2-2 Figure 2-1 Exciter EX23G installation 950115B.pdf Page 2 of 7 Lyngsoe Systems 2.1. Exciter EX23G EX23G Connections Power Connections WARNING Before you start the installation, check if the Power Supply provides the specified output voltage – 22Vac +/- 10% or 25.2-30.8Vdc, and min. 0.5A; any polarity can be used for the dc output. 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 and 3 for ac voltage and terminal 2 (middle) for the ground. Plug in the power connector into any of the corresponding headers on the EX23G. The POWER LED (green) goes ON. 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. 950115B.pdf Page 3 of 7 Lyngsoe Systems 2.2. Exciter EX23G PC Software Configuration The simplest way to control EX23G is by using a Terminal Emulation program on the PC. The general configuration procedure consists of: • Open a Terminal Emulation program on your computer (Procomm, HyperTerminal, etc). • Configure the computer’s COM port to which the EX23G is connected. The default configuration for the COM port is: COM port - COM1; Data rate - 19200 bps; Data bits - 8 bits; Parity – none; Stop bits – 1; Flow control – none. • Use an adapter from USB to RS485 (LS PN 600057) • From the PC send commands to EX23G and observe the responses on the PC. Other dedicated software can be used to control EX23G as long as the correct commands are provided for EX23G. 3. Operation 3.1. Remote control The operation of the Exciter EX23G is controlled by commands and parameters. The parameters values are set into EX23G during the configuration session. This configuration is controlled by a PC running serial communication program like Procomm, through a serial communication link type RS485. There are several specific commands to configure or to query the EX23G parameters values. When EX23G is connected in a network, it shall receive a unique address called NetId. The NetId is an integer in the range 0 to 255. Each command transmitted to an Exciter EX23G shall be preceded by a prefix specifying its NetId and must use the following syntax: #NetId; the prefix #NetId is separated from the command itself by a space. The basic configuration of the communication network is presented in figure 3-1. RS485 Network 3.2. LF Field Generation The LF excitation field generated by EX23G has a 125 KHz carrier modulated with 950115B.pdf Page 4 of 7 Lyngsoe Systems Exciter EX23G ExcitationId frames. By using two loops to generate the field the resulting excitation field provides a more reliable excitation for tags (independent of their orientation) with a compact spatial presence compared with the previous exciter models. 3.3. UHF transmitter Exciter EX23G includes an UHF transmitter capable of transmitting its digital ID using messages on 433.92 MHz channel. These UHF messages can be used to communicate wirelessly the EX23G operational status and in the same time to check the reception performance of the Readers located in the neighborhood. The interval of time separating two transmissions and the number of messages in the packet are programmable by parameters, Table 2 listing the available user-programmable parameters. 4. Commands and Parameters Table 1 presents the commands accepted by EX23G.
