ERW8M

Overview:
Vishay RFWaves makes a continuous effort to support its customers. As part of this effort, our team offers extensive application notes, design documents and a very convenient to use evaluation kit, all enabling very simple product integration. The ERW8M is Vishay RFWaves new evaluation kit for its new transceiver module, the RFW8M.

This is an easy-to-use evaluation environment for applications that will use the RFW8M transceiver module, together with the RFW-D100 interface chip. This evaluation kit also includes an 8051 PLCC44 in-circuit emulator socket and RS232 serial interface for PC to ERW8M communication.

Features
     Power supply circuitry input of 2.2 V to 10 V and output of 3.3 V (for the RFW8M)
     Battery or DC input power capability
     Two 20-pin headers containing all RFW-D100 and MCU interface for prototype
     8031\51 PLCC44 in-circuit emulator socket
     128-bit Serial EEPROM
     High-frequency oscillator for RFW-D100 operation
     RS232 line driver for PC to board communication, including a 9-D-type connector
     6-pin connector for the RFW8M module.
     6 user debug connectors containing all digital lines
     4 user indicator LEDs reflecting system status
     MCU reset switch and user-defined switch

Contents:

Reference Software Support:

The ERW8M has three operation modes:

1) Working without PC interface: In this mode, the ERW8M can be used to demonstrate the range of the RFW8M transceiver.
2) Working with a single PC: The receiving unit is connected to a PC, while the transmitting unit remains mobile. In this mode, the user can see the received data, and manipulate the receivers’ configuration. This in turn allows for a better estimation of the RF link quality and range.
3) Working with Two PCs: This mode allows the user to control the setting of both the receiving and transmitting units. By controlling parameters such as frequency channels, protocol addresses and type of transmission, the user can gain comprehensive understanding of the possibilities provided by RFW8M transceiver.
