PRODRIVE MOT130 RFID Reader Control Board User Manual

Introduction

This specification document describes the hardware-level specification for the RFID Reader.

Background and context

The RFID Reader is designed to operate in industrial vehicles. The objective of the RFID Reader is to support operator identification and access control.

The RFID Reader shall be mounted in an accessible area in a vehicle. After powering up, it accepts RFID cards. Once it detects the RFID, the data read from the card or device will be sent to the master controller over RS232 port.

• The RS232 pins are ESD protected: +/-15kV HBM
• Serial interface characteristics are listed in Table 3-1.

Table 3-1: RS232 performance

RFID

The RFID Reader supports contactless communication of RFID tags based on the 13.56 MHz and the 125 kHz system.

The 13.56MHz RFID system supports:

• ISO14443 A/MIFARE
• ISO14443 B
• ISO15693
• NFCIP-1
• Write mode is not supported
• Maximum transmit power: 200mW / +23dBm

RFID 125 kHz

The RFID reader includes a 125 kHz front-end with following features:

• Antenna driver with carrier frequency of 125 kHz
• Write mode is not supported
• Maximum peak transmit power: 1 W

Power supply and consumption

The RFID Reader has to be supplied through CN_RS232 connector. Table 3-2 lists the power supply requirements.

Classification

Insulation / grounding concept

The RFID Reader does not contain hazardous voltages. Therefore safety isolation is not required.
Furthermore functional isolation is not required by the customer. As a result the RFID Reader is constructed with a single ground plane.

Radio

The applicable radio standards for the RFID receivers are listed by Table 6-8.

Conditions of Use

This section lists the requirements and conditions to consider during installation of the RFID Reader.

1. The RFID Reader shall be used with an external fuse or current limiter with a maximum rating of 10A.

FCC compliance statement

This device includes antenna elements that radiate electromagnetic energy. The device must not be collocated or operating in conjunction with any other antenna or transmitter but does not require installation instructions to provide a minimum separation distance.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Caution! Any changes / modifications not approved by the responsible party could void the user’s authority to operate the equipment.

Industry of Canada statement

This device complies with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions:

1. this device may not cause interference, and
2. this device must accept any interference, including interference that may cause undesired operation of the device.

This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment does not require to be installed and operated with minimum distance between the radiator & your body.
