Synchronization problem

[eustahijE1992]

Hello everyone,

I'm working on a roller coaster ride simulator, and I'm using DasyLab to control the operation of the machine. The simulator is basically a wooden box which is actuated by hydraulic pumps. 

I have a simple DasyLab program which controls the ride and it works well. I'm using a DT9813 analog input, which controls my closed loop feedback, and a DT9853, which sends signals generated through the following program to driver cards which control the pumps. 

This program works well. However, instead of the generator I want to control the operation of the machine directly through a joystick. I connected the joystick (0-5 V) to DT9813 and directly was giving different voltage inputs by moving the joystick in a certain direction. The problem I'm running into is that the signal that I give through the joystick is delayed too much, almost one second. Does anyone have any idea why is this happening? I will appreciate any help.

Have you already been in contact with Data Translation (Measurement Computing) support on this? 

If so, you'll get the best support for the hardware by talking to them (us). You describe what is likely to be a driver/device specific issue. It may be wiring, it may be sample rate and block size settings, it may be an issue with the driver or even the device firmware.

When you have an issue related to how DASYLab supports and works with specific hardware devices, we need to know:

DASYLab Version (latest is 14.0.1), driver version, hardware library version (open layers), operating system, and the model of the devices. You've only listed the DT model numbers. 

Data Translation devices are supported by Measurement Computing. Contact us at www.mccdaq.com, and include the information requested:

• the version of your DASYLab software, such as 14.0.1
• the level of your software (Lite, Basic, Full, Pro)
• the exact DAQ device by manufacturer and model, list all devices
• the version of the drivers/libraries for the DAQ device
• your operating system and computer,
• and, if appropriate, a copy of your worksheet.

Also, this sounds like a perfect example for the DASYLab 2016 State Machine module!
