 The next step will Install the Drivers, click the "Install" button. This will complete the final

installation.

 You may need to restart your computer for the drivers to take effect. Do so if required.

 Attach the 4D Programming Cable to the USB port and you're ready to use it.

How to Increase available current from the USB port:

The link in the Software and Utilities section, on the left, "CP2102-Settings" contains a nice little utility

program to increase the power (current) available from the Programming Cable. Default is 100ma which

may not be enough for some devices. Up to 500ma is available on a USB port but the device

(Programming Cable) must ask for what it needs from the host i.e. from the PC.

Here's how to do it:

 Connect the 4D Programming Cable to the USB port.

 Unzip the file into a folder, name it anything you like.

 Run the application "CP210xSetIDs.exe".

 A window will open up with lots small selectable boxes, we're only interested in "Max Power (2

mA Units)".

 There you'll see a default value of 32 (this is in hex, dec=50). Each increment of this value will

provide an extra 2ma of current from the PC to the Programming Cable. So if we want to draw

200ma we need to enter 64 and for 300ma we need to enter 96 and for 400ma enter C8 and so

on.

 We can be greedy and go for the maximum so we need to change the value of 32 to FA. You can

do so by highlighting this value with your mouse and typing FA. Maximum allowable current is

500ma for a USB device, so do not enter anything more than FA otherwise the setting will not

take effect.

 Once the desired hex value is entered for the current we need, tick the small box next to it.

 Now click on the "Program Device" button (large button on the right hand side) and make sure

the Programming Cable is attached to the USB port. This action will program the USB power

descriptors within the CP2102 chip inside the cable with the power value that was entered.

 Now close the application.

 The above procedure only needs to be done once. So the next time the Programming Cable is

attached to the USB port, it will receive the appropriate current from the USB port.
