1 FEATURES
SLRM900
* 24 V DC power supply * 13.56 MHz carrier frequency * RS232 serial interface, 115.2 or 57.6 kbaud data rate * Regulated RF output power, software adjustable from 2 up to 10 W at 50 * Software adjustable modulation index from 10% to 20% * Firmware upgradable via RS232 interface * Programmable input and output ports (optional) * Electronic Article Surveillance (EAS) stand-alone mode (EAS output signal optional) * Anticollision capability * Support of both standard and fast mode * BundesAmt fuer Post und Telekommunikation (BAPT) and Federal Communications Commission (FCC) approval * CE compliant. 2 APPLICATIONS Optional input and output ports, and an RS232 interface offer the possibility to connect the unit to a microcontroller or PC. The SLRM900 is designed to access all types of labels and transponders that are based on the I-CODE1 label IC. Read and write functionality is included, as well as sophisticated ways to use the anticollision capability of I-CODE. High emphasis is put on long range functionality, which makes the SLRM900 suitable for gate antennas and tunnel reader applications. In order to provide the appropriate output power level for various types of connected antennas, the output power may be adjusted, using simple software configuration commands. Many reference installations with high demands on anticollision, reading range, and data reliability in noisy environments, have proven the capability of both the reader module and the I-CODE1 label IC. This document describes the reader hardware, interface, and connection of the antenna.
* Long range reading appliances in I-CODE(1) systems. 3 GENERAL DESCRIPTION
Generally, the SLRM900 can communicate with smart labels based on Philips I-CODE1 label IC SL1ICS3001. It consists of a 2-way communication transmitter and receiver, for generating, transmitting, receiving, and processing identification signals.

7.1.3
I/O PORTS
The SLRM900 is part of a complete Radio Frequency Identification (RFID) system (see Fig.6). The SLRM900 can communicate with I-CODE smart labels. The device consists of a two-way communication transmitter and receiver, for generating, transmitting, receiving, and processing identification signals. In the transmit mode, the microcontroller board generates data whereas the RF board uses this signal to modulate a carrier. This modulated carrier will be amplified, and transmitted by the antenna to the label. This label will subsequently generate its response, which will be picked-up by the SLRM900 in the receive mode, and processed by the digital hardware. By using the RS232 serial interface (or the optional input and output ports) the output parameters of the module can be set. 7.1.1 I-CODE labels
There are 6 input ports, 4 output ports, and one EAS signal output port available on the microcontroller board (see Section 6.5). These ports are software programmable. The input and output ports are not lead out of the metal housing and therefore not ESD protected. 7.1.4 ANTENNA
A 50 antenna has to be connected to the antenna connector. This antenna has to be designed according to application note "I-CODE design of Read/Write antennas". 7.1.5 POWER SUPPLY
To work with the SLRM900, an external linear regulated power supply has to be used. Using the supplied power supply cable is recommended, in order to comply with the EMC and EMI limits (see Section 7.5). The reader module contains filtering circuitries for the power supply. However, some requirements are to be fulfilled by the power supply. The maximum ripple of the supply voltage must not exceed the maximum values specified in Table 2.
The SLRM900 is designed for communication with smart labels based on Philips I-CODE1 label IC SL1ICS3001. 7.1.2 HOST
The connection to the host (e.g. microcontroller or PC) is a serial interface on RS232 level for data transmission. For the protocol please refer to data sheet "SLRM900 I-CODE Long Range Reader Module, protocol Reader-Host".

The RF power regulator keeps the antenna output voltage to a level determined by software settings. Also, by using software settings, the modulation index can be set, according to data sheet "SL1ICS3001 I-CODE Label IC". The required modulation index has to be re-adjusted after any change of the RF output power and at large temperature variations.

7.3.1.5
Receiver, filter, demodulator, and ADC
An amplitude modulated signal is received from the I-CODE1 label IC. After filtering, demodulation, and amplification, the analog data signal is converted by the 12-bit ADC for further digital processing.
The available software for the SLRM900 is contained in document "SLRM900 I-CODE Long Range Reader Module, protocol Reader-Host". 7.3 Reader hardware
7.3.1.6
Opto-couplers
All internal analog and digital signals between the RF board and microcontroller board are galvanically separated by opto-couplers. 7.3.2 MICROCONTROLLER BOARD
The internal electronics of the SLRM900 can be divided in two major units: * RF board (see Fig.7) * Microcontroller board (see Fig.8). 7.3.1 RF BOARD
7.3.2.1
Microcontroller
7.3.1.1
Voltage regulation
The microcontroller processes the protocol for the communication between the I-CODE labels and the SLRM900. The serial interface signals are converted in such a way, that the labels are able to process them, and the outgoing signals from the labels are converted into serial interface-compatible signals. Another important microcontroller task is its control function. Software control offers the possibility to change both the RF-output power and the modulation index.
All necessary internal voltages for the module are derived internally from the 24 V DC power supply voltage.
7.3.1.2
Clock generator
This part generates the 13.56 MHz clock frequency for the transmitter amplifier. A divided clock signal is connected to the microcontroller for synchronization purposes.
7.3.2.2
RS232 interface
7.3.1.3
Modulator and transmitter amplifier
The device communicates with the host (processor or PC) via a serial interface, using a jumper-selectable baud rate of either 57.6 kbaud in standard mode, or 115.2 kbaud in fast mode (see setting for JP4 in Table 3).
To transmit data to the I-CODE labels, the carrier has to be modulated by the modulator with a digital signal from the microcontroller according to data sheet "SL1ICS3001 I-CODE Label IC, protocol air interface". The transmitter amplifier amplifies the modulated carrier signal.

7.5 EMC and EMI 7.6
SLRM900
Safety and reliability considerations
The SLRM900 is designed in such a way that it is possible to build systems with it, which are in conformance with EMC and EMI standards. Electromagnetic emissions comply with the guidelines in BAPT 222 ZV 122 and EN 300 330. Electromagnetic immunity complies with the guidelines in ETS 300 683. The conformance to EMC and EMI standards can only be granted for systems, not for components. The following measurements have been passed: * EMI: EN 300 330, BAPT 222 ZV 122, FCC 47 part 15 * Immunity: ETS 300 683. The following configuration is in compliance with the telecommunication standards: * SLRM900: output power 4 W at 50 ; modulation index m = 15%; standard mode * Linear power supply (according to the recommendations in Table 1), connected via the supplied power supply cable * Antenna from the I-CODE evaluation kit: - size: 38 cm x 28 cm - number of turns: N = 1 - quality factor: Q = 30 - impedance: Z = 50 - = 0 - according to application note "I-CODE, Design of Read/Write antennas".
The SLRM900 has implemented measures for high reliability. 7.6.1 ANTENNA RUPTURE AND ANTENNA SHORT-CIRCUIT
The SLRM900 does not immediately get damaged in case of either an antenna short-circuit, or an antenna rupture with short duration. However, permanent antenna short-circuit, or antenna rupture, will definitely damage the SLRM900. The supply current of the SLRM900 will be limited at typical 1.6 A. 7.6.2 SUPPLY VOLTAGE
The SLRM900 is protected against short supply voltage peaks and incorrect polarity for a short time, but permanent incorrect supply will definitely damage the device.
