Figure 5-8 shows the PCB layout for the Active Cable. The following pinning is possible:
Jumper 1 | Jumper 2 | Description |
---|---|---|
Off | Off | The active cable has no power and does not function. |
Off | On | The active cable receives power from target socket. For this option, the target socket must have its own power supply. |
On | Off | The active cable receives power from the JTAG connector. |
On | On | The JTAG connector powers the active cable and the target socket. For this option, the target socket must not have its own power source, as this would cause a not defined state. |
