RV2 Video Processor
Recording Sessions
When OpenWorkbench is set to ‘Record’ mode and a Video_Access macro is present
in the circuit, Workbench sends a UDP packet over the network to find RV2s. If
Workbench doesn’t receive a response within five seconds an error message is
displayed and recording begins without video storage. The UDP packet contains the
tank and block name so the RV2 can properly name its files. Once an RV2
responds, OpenEx begins sending frame triggers and recording data. When OpenEx
switches modes to anything other than ‘Record’ a packet is sent to the RV2 to
close the files it is currently writing to and wait for the next recording session.
Frame Rate
The maximum frame rate depends on the camera’s exposure setting. This value can
be adjusted using the ‘Lighter’ and ‘Darker’ buttons on the RV2 touch screen
interface. The frame rate is overlaid on the camera image in the Live tab. The
current maximum rate based on the camera settings is displayed when the camera is
in free run mode.
Note: When recording data it is important that the desired frame rate is no greater than
the observed free run frame rate, otherwise frame loss will occur. A lost frame
counter is overlaid on the lower right corner the camera image. To reset this
counter, see the Status tab. A reboot will also reset the lost frame counter.
Hardware Requirements
Basic requirements include a VGAC, an RV2, an RZ equipped with at least one
video fiber optic port, one fiber optic cable for connection between the RV2 and RZ,
the VGAC power cable, one Gigabit Ethernet cable to connect the VGAC to the
RV2, a PC equipped with an Ethernet port or an Ethernet jack connected to a local
area network, and an Ethernet cable.
Setting ‐ Up Your Hardware
Important! Make sure that all cables are connected before powering on the RV2.
