Problems related to the SEEprog



PC interconnection, and their

removing

The LPT port have to be set to SPP (standard parallel port) mode. In some cases BIOS of

computer don't allow to switch proper mode by software, therefore we recommend to do it

manually. If you have any problems with SEEprog  PC interconnection, see section

Common notes please.

Manipulation with the programmed device

After selection of desired device for your work, you can insert into the open ZIF socket (the

lever is up) and close socket (the lever is down). The correct orientation of the programmed

device in ZIF socket is shown on the picture near ZIF socket on the programmer's. Only 8

bottommost pins of the DIL14 ZIF socket are active! The programmed device is

necessary to insert into the socket also to remove from the socket when LED BUSY light off.

Warning! SEEprog programmer hasn’t protection devices, which protect the content of

programmed device against critical situations, for example power failures and PC failure

(interrupted cable...). Moreover, a device is usually destroyed in the programming mode due

to forced interruption of the control program run (Reset or switching the computer off) due to

removing the connecting cable, or unplugging the programmed device from the ZIF socket.

Incorrectly placed device in the ZIF socket can cause its damage or destruction.

Technical specification

HARDWARE

Socket and control of pins:

• DIL/ZIF socket (300mil)

• each pin is possible to set in position Low and Pull-up

• from each pin is possible to read

• support of Low Voltage devices

For works with serial EEPROM are used nearest 8 pins to lever, unused pins are not

connected.

DEVICE SUPPORT

• EEPROM IIC (24Cxxx)

• EEPROM Microwire (93Cxxx)

• EEPROM SPI (25Cxxx)

• specially devices (digital thermometers, ...)
