Products from Grantronics

In the course of designing products for our usual clients, we sometimes have to design other equipment. Or maybe it was just something we wanted to do. Either way, here are a few things we have designed which should be useful to many fellow Embedded Design Engineers.

		485N: An automatic RS232/RS485 interface that is easily user programmed for any baud rate from 45 to 115,200 baud. Uses an AVR microcontroller.
		GLC3: A small "logic controller" that has 8 digital inputs and 8 digital outputs, RS232 or RS485 serial port, buzzer, LCD and runs from 12Vdc.
		GMC75X: A small credit-card sized CPU that can accept a range of single-chip 8051 derivative CPUs. Build a 'C' stamp (OK, a 'C' credit card).
		PC2I2C: Interface adaptor and cable which allows the GMC75X EEPROM to be read or programmed from your PC.
		GP-AT: A very versatile programmer for the Atmel range of Flash 8051 and AVR CPUs (DIP, PLCC44 and SPI). Also does 8-pin EEPROMs.
		SOIC20: An adaptor for the 20 pin SOIC versions of the AT89C2051 (for the GP-AT programmer).
		51/2051: For those who have an 8051 ICE but want to target the AT89C2051. This 40-to-20 pin adaptor includes a comparator to simulate the comparator in the AT89C2051.

We also have some industrial controller products and adaptors for programming PLCC AVRs that will be released soon.
