JTAG Connection

Mechanical Description of the 20-pin Debug Cable

This connector is defined by ARM. LAUTERBACH’s debugger 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.
