The Relay objects corresponding to relays connected to MO USBIO 4x4 device are created under the Video Capture Device objects of the MO USBio type. One can create up to 4 Relay objects under the Video Capture Device object.
Note
One is to specify the number of PCI channel that is not used by another object.
When configuring the Relay objects one is to specify the channel numbers of relay connection to MO USBIO 4x4 device. Channels are numbered according to external pinout of the device (see Connecting MO USBIO 4x4 external module or Connecting MO USBIO 4x4 cards sections).
To change the channel numeration, use the Channel Number list on the settings panel of the Relay object.
MO USBIO 4x4 device allows connecting up to 4 relay channels according to the license key file.
The figure below shows an example of the channel numeration configuration of 4 relays connected to one MO USBIO 4x4 device.
The channels of the second (next) device are numbered 1-4.
