Connects via serial port. No special
PC software required - all programming "intelligence" in on-board firmware.
Automatic or manual chip identification. Use any terminal emulation software
on any computer eg. Hyperterminal supplied with W95/98/2000/XP
(click here for setup information).
Requires minimum 16VDC supply. Most 12VDC wall adaptors should supply this easily.
Current capacity of adaptor should be at least 150mA.
Provision for 20 and 40 pin ZIF sockets but not supplied.
K149F - Serial Port PIC Programmer with ICSP, Assembled & Tested
K149F is the latest version of the K149 series of PIC programmers produced by DIY Electronics. It was re-designed to overcome an electrical noise problem in the K149BC programmers - a problem that was intermittent from one programmer and PC setup to another. This made it impossible to guarantee correct operation of the programmer.
The noise problem was due mainly to the PCB layout but was also affected by other factors such as the USB interface and the common sharing of the 6MHz crystal between the USB chip and the microcontroller. In redesigning the programmer the following changes were made:
1. USB interface removed - serial port only.
2. Crystal replaced with 3-pin resonator.
3. Some current limit protection added to the Vpp supply to try and eliminate blowing up the switching transistors.
4. Extra LED added to indicate communications with the PC.
5. ICSP programming header changed to 6-pin for compatibility with K150.
6. Smaller PCB - 70 x 68mm
In all other ways K149F is electrically equivalent to K149BC. It uses the same Windows interface and the same firmware chip.
K149F is supplied fully assembled and tested.
NOTE: The 40-pin wide slot ZIF socket is not supplied with the kit and must be ordered separately if required.

Some information here from Bob Axtell about ICSP programming and the PIC programmer kits. Also includes a useful tester for checking out your programmer (if required).
- Serial EEprom Programmer
PC parallel port programmer for the 24xxx and 93xxx EEPROMS. Supports 8 bit EEproms only. A 16 pin socket is used on-board. The top 8 pins are for the 24xxx eeproms and the bottom 8 are for the 93xxx eeproms. DOS-based software (does not work under Windows 2000/XP) allows the user to read, program and verify eeproms, save eeprom contents to disk and view eeprom contents. The PCB will take a 16 pin ZIF socket (not supplied).
The following eeprom types are supported (generic part numbers are used ie. 2416 instead of 24C16):
* 2401, 2402, 2404, 2408, 2416, 2432, 2464, 24128, 24256
* 9346, 9356, 9366, 9376, 9386
