The Hollyland DB25 Male to DB9 Male Tally Cable (Model: HL-TCB04) is an official OEM interface adapter designed exclusively for the Hollyland Wireless Tally System.
While the female DB9 variant (HL-TCB05) connects to switchers that feature an outward-facing male port, this DB9 Male version functions as a direct interconnect for broadcast switchers, camera control units (CCUs), and vision mixers equipped with native female DB9 tally outputs. It accurately carries low-voltage parallel dry contact closures to change the colors of your remote, wireless on-camera tally lamps.
Understanding the Component Interface
-
DB25 Male Terminal (Tally Station Side): Standard 25-pin D-Sub connector that plugs into the master parallel tally input matrix on the rear panel of the main Hollyland Wireless Tally base station box.
-
DB9 Male Terminal (Switcher Output Side): Standard 9-pin connector (also called a DE-9 plug) featuring an outward-facing pin arrangement inside a 2-row footprint (5 pins over 4 pins). It hooks directly into the switcher's female tally port without requiring any intermediary adapters.
Core Hardware Features
-
Zero-Latency Dry Contact Switching: Custom-wired to safely pass low-voltage parallel relay ground signals. The moment an operator switches a source into the Program or Preview bus, the circuit completes instantly, giving you instantaneous red/green tally updates on set.
-
High-Density Copper & EMI Shielding: Fabricated with high-grade multi-conductor copper wiring wrapped inside a dense electromagnetic interference (EMI) shield. This prevents signal crosstalk or false tally triggers caused by studio power lines, lighting ballasts, or heavy-duty server racks.
-
Captive Screw Mechanical Locks: Both the DB25 and DB9 connector heads are molded from high-impact PVC and equipped with integrated metal thumbscrews. This locks the cable tightly into your production station, completely preventing accidental signal disconnects from physical cable pulls.

Pin Layout Setup Check: If you plug this cable into your switcher and find that the camera channel indicators are mixed up (e.g., Camera 1 lights up when Camera 3 is selected), you don't need to cut or rewire the harness. Go to the master Hollyland Wireless Tally Station's front panel and open the Sequence Learning menu. This software feature allows you to digitally remap the data incoming from the DB9 pins inside the station's memory, ensuring your camera lines match perfectly across your entire control layout.
