JTAG Connection
Mechanical Description of the 20-pin Debug Cable
This connector is defined by ARM. LAUTERBACH’s debuggers ’JTAG Debugger for ARM7’ (LA-7746) and
’JTAG Debugger for ARM9’ (LA-7742) and ’JTAG Debugger for TMS320’ are supplied with this connector:
This is a standard 20 pin double row connector (pin-to-pin spacing: 0.100 in.).
We strongly recommend to use a connector on your target with housing and having a center polarization
(e.g. AMP: 2-827745-0). A connection the other way around indeed causes damage to the output driver of
the debugger.
