ScanTool Ready-or-Not - Manual (Page 19)

8 Accessories
8.1 OBD-II cables
5.2 USB to RS232 converter
The Ready-or-Not can be used with a number of inexpensive OBD-II
cables, including cables with right angle J1962 connectors.
The ability to replace a worn out OBD-II cable is indispensible in
heavy use applications. You can place your order online, by phone,
or fax (see previous section).
Some modern PCs (especially portable computers) do not have a
serial port, necessary for programming the Ready-or-Not. The
solution is to use a USB to RS232 converter, which plugs into any
available USB port, and creates a virtual COM port.
The USB to RS232 converter must be used with the
serial cable supplied with the Ready-or-Not.
Important:
A word of caution: Some commercially available USB to Serial converters do
not meet the RS232 voltage and current specifications, and will not work with the
Ready-or-Not — despite the fact that they often cost significantly more than the
competitively priced serial converters available from ScanTool.net, LLC.
