Pin's are High when connecting the IOW24

[nl2ttl]

Correct me if i'm wrong, but at the moment i have 4 relais on the IOW24. When i connect the IOW to the USB Port the pins are directly after init high.

The ports i talk about are:

P1.0
P1.1
P1.2
P1.3

This results in that my relais switch directly when i connect the IOW to the usb and my lamps wil turn on imiditly and thats not what i want. Is there a solution for it without a inverter IC.

.. as is clearly stated in the datasheet for the iowarrior.

No

what kind of driver do you use for your relay? if you use an pnp transistor, as it it shown in the datasheet, you won't have that problem...

How simple can it be i used a bc547 instead off a 557 problem fixed thank you!
