GOEPEL TAP connector pinout
All but a few of GOEPEL's JTAG / boundary-scan controllers / TAP transceivers use the same pinout for TAP connectors:
| Signal | Pin | Notes |
| TCK | 1 | output |
| TMS | 3 | output |
| TDI | 5 | input; connect this signal to the UUT's TDO |
| TDO | 7 | output; connect this signal to the UUT's TDI |
| /TRST | 9 | output |
| GND | 2, 4, 6, 8 | connect at least one GND to UUT Ground |
| PwrRly | 10 | +5V signal; can be used to switch power relays or other control circuitry; otherwise unused |
GOEPEL uses standard 100 mil 2 row by 5 pin connectors (male headers) for TAP interfaces.
Note that the pinout for TAP connectors, PIP connectors, and AUX connectors is printed on the bottom side of the SFX-TAP Transceiver and the ScanBooster hardware as well as referenced in the respective hardware manuals.
