Sabertooth 2 X 32

Hi
I have a question about the power outlets P1 and P2
I have a small RC controlled trolly to be used on a construction site. This requires that I have a beeper and flashing light.
Hoping to use the Power outlets to operate light and beeper. I seem to be unable to get the power outlets to work. Despite setting the board to brakes and timeout limits to 0 as per manual its not working. As I understand I connect - to the P outlets and + to the main power input
Can anyone give me some advice on this?
Thanks in advance

Other community members might jump in here, but I'm not really that familiar with the Sabertooth Motor drivers myself.

I did a quick search and found that Dimension Engineering does has an FAQ Knowledge base and help desk if you can't find the info here.

Here's the link to Dimension Engineering: https://help.dimensionengineering.com/knowledgebase.php?article=16

Sounds like you have a Sabertooth 2x32. Have you used the Describe software to set the function of the power outputs P1 and P2? I pretty sure these ports are configured at the factory to be used as voltage clamps. 

If not you will have to hook your sabertooth up to your computer, download the free Discribe software from Dimension Engineering and set up these ports to be used as power outputs. The manual Jermie pointed to will guide you through the process nicely. According to the manual you also need to adjust the voltage level to your needs. In this mode the power output is directly controllable. A control setting of 2047 corresponds to full
power and a control setting of -2047 corresponds to zero power. You'll need to use your multimeter to see what you actually have as you adjust. looks like you can have a power output up to 33.6V . looks like you will need to choose Controllable Output in the drop down menu of the P port you want to use. 

Also make sure you have all your dip switch settings correct. Dip sw3 controls weather you use a battery or power supply. 

If you are needing only 5vdv you can just use the 5v port found to the left of P1 & P2. This is a 5vdc power out port. Ports P1 & P2 can handle up to 8 amps but the 5vdv power out port can only handle 1 amp load.

Thanks Jeremie and Dave ... I have searched the Dimension knowledge base and have found nothing near my problem, in fact only one article that mentions power outlets.
I do not intend to control the power outlets, just do as the manual suggests ( page 46) use the power outlets as Braking and achieve a power source for my beeper and flashing light when device moves. 
Despite using the DEScribe software, setting the power outlets to Braking, uploading and operating (12v battery) whilst using the diagnostics page the power outlets still only register -100%  (off), also have a beeper connected (silent)  Also uploaded latest firmware.

Thanks for the input so far

Hi 
The answer to my issue has been found 
Don't set delays to Zero, have some delay even if small

Very nice. Good to know. I've got several 2x32 sabertooths in my robot and never used P1 & P2 as power outlets. I used them as voltage shunts as I run on power supplies. I get my different voltages needed for other devices from the main power supplies and step down voltage with buck regulators. Now I know how to use them as power outlets! Thanks for your work and sharing your knowledge.
