12c. Making a Chipless Blackcat

 

Ok so now you've got your Blackcat made up it might be wise to install a ten pin header onto your modems JTAG points to easily attach and remove your Blackcat.

And here's a little more info on making a Blackcat without a chip.

This is a simple method of making a non i.c BLACKCAT CABLE

 

Below is a list of the items you will need from www.maplins.co.uk

1 x JB59P [2X5 DIL IDC SOCKET]

1 x JB85G [2X5 IDC PCB HEADER]

1 x XR74R [FLAT IDC CABLE 20 WAY (SEPARATE INTO 2x 10 WAY)]

1 x YQ48C [D-SUB 25 WAY plug]

1 x JW91Y [25W D TYPE HOOD]

 

 

Open the DIL idc socket and slide the idc cable through and squeeze tightly to close the socket.

Take note of the way the socket is facing below.

At the other end of the idc cable cut the wires like in the pic below.

You will not be using 3,5,7,9 so cut and remove these wires

Solder wires to the rear of the 25-way plug, make sure to follow the pic below & above.

The number 1 wire should bridge 4 pins on the bottom row as in picture

 

Solder the PCB header onto your surfboard 5100 series

With the cut out facing as in the picture below

...Please note if you intend to use the buffered version of blackcat the cut out should face the opposite way

Failure to do this will render the header useless and you will have to remove and re solder.

Once finished your cable should connect like the picture below the next step is to load software and connect the cable to your pc.

Ok so now you've got your Blackcat made up it might be wise to install a ten pin header onto your modems JTAG points to easily attach and remove your Blackcat
