NOTE: in Mach-1 Motion version 4.5.0.1+ (ESP302), the software will automatically search through all DAQ ports. The method below is not necessary.
This error is usually caused by having an incorrect DAQ# in the Mach-1 Motion configuration file. Windows can sometimes change this number during a Windows Update.
To fix this, the DAQ number can be changed in the Mach-1 Motion Configuration/Hardware menu. Valid numbers usually fall between 1 to 10.
Please change the number, open Mach-1 Motion and verify there is no error. Repeat until Mach-1 Motion initializes normally.
In other words, change ONLY the DAQ# by increasing it by +1. Try opening Mach-1 Motion. If the error -88705 still appears, close, reopen Mach-1 and repeat the +1.
If there are still issues after trying different DAQ numbers, please restart the PC in case the issue was regarding the DAQ PCIe card driver instead.
