The Hollyland DB25 Male to HDB15 Male Tally Cable (Model: HL-TCB06) is an official OEM interface adapter designed exclusively for the Hollyland Wireless Tally System.
While the HDB15 Female variant (HL-TCB07) functions as an expansion port to receive custom external pin configurations, this HDB15 Male version serves as a direct, hardware-to-hardware interconnect. It maps physical relay logic straight from the parallel output block of compatible production switchers into the main command deck of the Hollyland Wireless Tally Station box.
Key Connector Form Factors
-
DB25 Male Terminal (Tally Station Side): Plugs securely into the 25-pin parallel input matrix layout on the rear panel of the master Hollyland Wireless Tally station.
-
HDB15 Male Terminal (Switcher Output Side): Features a high-density 15-pin layout arranged in 3 rows of 5 pins with outward-facing pins. This male form factor matches the standard tally output footprint on professional video switchers, eliminating the need for an intermediate gender-changer or breakout panel.
Core Structural & Functional Features
-
Dry Contact Relay Optimization: Engineered to carry low-voltage parallel contact closures natively. The moment an operator pulls a source into the Program or Preview bus on the switcher console, the corresponding circuit path safely grounds, sending an instant command across the HL-TCB06 wire harness to change the on-camera tally lamp color.
-
High-Density Copper Core Construction: Built with heavy-duty multi-conductor copper wiring wrapped inside an internal RF/EMI shield layer. This prevents transmission drops, delay lag, and electrical crosstalk caused by adjacent broadcast server racks, massive video walls, or main studio power runs.
-
Industrial Strain-Relief Boots: Both the DB25 and HDB15 connector housings are molded from durable, high-impact PVC and equipped with integrated, captive metal thumbscrews. This mechanical lock holds the cable firmly into your equipment rack, protecting the connection terminals from vibrations or accidental tension pulls.

The HDB15 Pin Pattern Rule: It is easy to mix up HDB15 with standard DB15 cables in dark engineering spaces. Always remember that a standard DB15 layout uses 2 rows of wider pins, while this HDB15 configuration uses 3 rows of high-density pins. Double-check your vision mixer’s backplane interface guide to verify it accepts a high-density 3-row layout before seating the HL-TCB06 into your equipment stack.
