From The RadioReference Wiki
The 2051 is a 20 pin version of the 8051. It is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read only memory. Atmel manufactures the chip using high-density nonvolatile memory technology. The 2051 and is compatible with the industry-standard MCS-51 instruction set. The PG2051 is a development programmer for the ATMEL AT89C2051. The AT89C2051 programmer is fast, small and simple to use. The programmer may be connected to a PC or other host by a serial cable. The data to be downloaded to the programmer is transmitted in Intel Hex format. The programmer will erase & program, verify, write protect. Then you remove it from the programmer and insert it into your board. The ATMEL website has an excel file which lists all the different vendors that make programmers. Some of them are pricey, a BP microsystems programmer is about $6000.00. The scanner automatically goes into the wired programming mode. PGM and WirEd appear. Page 76: Cloning Your Scanner You can clone all the frequencies, trunking talk groups, and fl eet maps programmed in your PRO-2051 to another PRO-2051 using an optional interface cable and software (available at your local RadioShack or www.radioshack.com).

The similar styled scanner as the Uniden BCT8 but with silver colored control panel (like all other newer Radio Shack scanners). It has one feature that it is not found on the BCT8 that is: Signal Stalker™ (similar to Uniden's Close Call™ feature) RF Capture Technology - Instantly tunes to signals from nearby transmitters.
The main difference in this scanner against the BCT8 is that the firmware is a mix of GRE and Uniden specifications; thus, any software for the BCT8 will not work with the PRO-2051.

Erase, Program and verify an AT89C2051 in one easy operation!
Programs in just 6 seconds!PG2051 - A Programmer for the Atmel AT89C2051, from AirBorn Electronics
The AT89C2051 is a 20 pin 8051 compatible microprocessor (including serial port) with 2k of FLASH memory, available from Atmel (see www.atmel.com). The PG2051 erases, programs, and verifies AT89C2051 chips in 6 seconds. As the AT89C2051 devices are FLASH, they can be reprogrammed as often as needed.
The PG2051 is driven by sending it a (standard) Intel hex file through its serial port. This means it can be driven by any operating system - all that is necessary is that the host has a serial port to send the data to the programmer (at 9600 baud) - the programmer will do the rest.
The programmer features a test switch which allows the owner to check if an AT89C2051 is blank, working, programmed or failed in just one second - without needing the PC connected.

The PG2051 is a development programmer for the ATMEL AT89C2051. The AT89C2051 programmer is fast, small and simple to use. The programmer may be connected to a PC or other host by a serial cable. The data to be downloaded to the programmer is transmitted in Intel Hex format. The programmer will erase & program, verify, write protect and security protect as it receives the file, according to the settings on its Dip switches.
| Insert an 89C2051 | - (Manual Test if desired) | Mode COM1:9600,N,8,2 |
| Download intel hex file | - (Causes programming) | Copy Myfile.hex COM1 |
| Watch LEDs | - (Indicates success) |
The PG2051 can be used stand-alone by inserting an 89C2051 and operating the Manual test switch, in this mode it indicates Tested, Blank and Verified checksum conditions.

| The AirBorn Electronics programmer described here connects to a Serial port, works under any operating system, and programs in 6 seconds by just copying the hex file to the COM port. There is also a programmer design available from Atmel that you can build yourself - although it does not share these features. Download the free programmer here, - but remember to get the software from Atmel, also. |
