V4 Logger

Configuration - Continued:

Most Broadcast Tools Switcher and closure devices can operate at 38400 and this will decrease

“latency” in processing closure or audio routing commands.

NOTE: OMT configures Broadcast Tools Switchers to operate in “Interlock Mode” versus “Mix” mode

with the ONAIR application. This is to prevent simultaneous audio content from multiple sources

being recorded through the switcher device.

There is additional Broadcast Tools configuration assistance in the Appendices of this guide.

Enable the “Invert Closures” if you logic appears to be reversed.

E.G.

The event log in Logger will display all closures when enabled and you may see the correct pin

closure but the logic may be reversed. It is assumed that “high” is active or on and “low” is inactive or

off. If you required “low” to be active, enable the “Invert Closures” and this will reverse the logic.

Closure Devices

If you have previously installed a DIO 24H Measurement Computing card then you only have to

enable the device from this section as the setup is automatic.

Although the SRC – 32 is no longer manufactured there are a great number of clients who still use

this device and therefore we still provide interfacing. Enabling the SRC – 32 closure device will also

control the GPI – 32 USB based closure device. Later versions of V4 will also have support for the

SRC – 16.

The WDT 500 Watchdog card is a PCI based card that will monitor PCI bus activity and output a

closure in the event PCI activity is halted. The closure is generally connected the computer’s reset

wire on the motherboard and this in turn reboots the PC. There is a separate WDT 500 installation

guide later on in the appendices of this Logger guide.
