db9 to db25 schematic

Hi,

I need the schematic or layout to make the cable for
the pic programmer.

Thanks.

You should specify which programmer you are using. There are a lot on the market, so be a little bit more concrete.

Hi,

In need of the DB9 to DB25 for the propic.

Thanks.

pic programmer using db25

Just use a 25 to 9 pin standard serialport adapter. I use a jdm programer that has a 9 pin connector that plugs straite in to a 9 pin serial port ( on a 1 to 1 9 pin exstention lead). At home my PC has a 25 pin serial port and i purchased a 9-25 pin adapter from Maplin.
Do not get confused with the type of adapter you would use for a serial port modem as these have a diferant pin assinment.

db25 db9 adapter pic programmer

You can do it youself, without buying from Maplin. It is very easy. This is full RS232 cabel (CD,DSR,CTS,RTS,TX,RX,DTR).

db25 db9 adapter jdm programmer

isn't it the db25-db9 connector/cable for propic2 uses a different connection from that of a standard db25-db9 serial cable?

Hi,
Be careful propic2 work on LPT port, not on the serial!!

parallel to serial db9 adapter schematic

Yes, ProPIC II is a parallel interface, not serial. A serial 9-25 adapter probably won't work!

If you have the schematic from the ProPIC website (**broken link removed**) the pin numbers for both plug sizes are marked on it. That's what I followed.

These are the connections you need to make between the 9 and 25:

Name >> 9-pin(ProPIC) >> 25-pin(PC)
d0 >> 1 >> 2
d1 >> 2 >> 3
d2 >> 3 >> 4
d3 >> 4 >> 5
d4 >> 5 >> 6
d5 >> 6 >> 7
Ack >> 7 >> 10
Clk >> 8 >> 8
Gnd >> 9 >> (18 to 25)

To explain, pin 1 on the ProPIC connector should be wired to pin 2 on the 25-way plug, etc. Pin 9 on the ProPIC connector (Ground) should be wired to any or all of pins 18 to 25.

Make sure you are wiring to the right pins - the pin numbers are usually marked on good quality D-connectors, they are numbered on male/female so that pin 1 always mates with pin 1, etc.

Cheers,
FoxyRick.
