# Wiring a Dump Button on the PDMII

## Scope

This TelosHelp Doc shows how to wire up a simple normally open Dump button on the PDMII.

## Question

I need some assistance getting a remote dump button to work with the PDMII through the DB15. Can yoiu help?

## Answer

Sure! On the PDMII, for a n/o dump button, jump Pins 9-10 and then wire the dump button to In1 (GPI1) on Pin 11 and Ground on Pin 8.

Also ensure that GPIO is Enabled.

[From the GPIO page in the online manual](/v1/docs/pdm-ii-user-manual):

The pin-out of the DB-15 connector is as follows:

| Pin Number | Function |
| --- | --- |
| 1 | GPO 1 |
| 2 | GPO 2 |
| 3 | GPO 3 |
| 4 | GPO 4 |
| 5 | GPO 5 |
| 6 | Not used |
| 7 | GPO Common |
| 8 | GPI Ground |
| 9 | GPI Power |
| 10 | GPI Common |
| 11 | GPI 1 |
| 12 | GPI 2 |
| 13 | GPI 3 |
| 14 | GPI 4 |
| 15 | GPI 5GPIO Enable |

GPIO Enable:

Hardware GPIO can be enabled or disabled in the GPIO Enable menu. When enabled, the rear panel DB-15 port is active.

For more information see the online manual at the link above.
