Upper DB-25 Connector — Control
The console’s on-air tally port is on the CRD-8 upper DB-25
connector. This is a simple relay closure that activates whenever
programmed input modules are turned ON. The port can be used to
control an externally powered tally light that requires a continuous
closure to function.
