JTAG:Quick Wiring Diagrams

Wiring for TUMPA and Standard Broadcom JTAG
Some routers require that pin1 of the JTAG on the router be connected to pin1 (VCC) of the serial connector on the router with a 100 ohm resister. Therefor pin3 of the TUMPA would be N/C.

Wiring for TUJA (Buffered) and Standard Broadcom JTAG
Some routers require that pin1 of the JTAG on the router be connected to pin1 (VCC) of the serial connector on the router with a 100 ohm resister. Therefor pinY5 of the TUJA would be N/C.
