Hollyland Spares - DB25 Male to HDB15 Female Tally Cable (for Wireless Tally System)The Hollyland DB25 Male to HDB15 Female Tally Cable (Model: HL TCB07) is an official OEM interface adapter designed exclusively for the Hollyland Wireless Tally System. While modern network setups use RJ45, many professional vision switchers, control panels, and multi camera interfaces route their parallel tally closures through High Density DB15 ports (often used for combined tally and intercom arrays). This cable serves as the precise pin to pin
The Hollyland DB25 Male to HDB15 Female Tally Cable (Model: HL-TCB07) is an official OEM interface adapter designed exclusively for the Hollyland Wireless Tally System.
While modern network setups use RJ45, many professional vision switchers, control panels, and multi-camera interfaces route their parallel tally closures through High-Density DB15 ports (often used for combined tally and intercom arrays). This cable serves as the precise pin-to-pin hardware bridge required to feed those switcher commands cleanly into the Hollyland Wireless Tally base station.
Understanding the Connector Interface
-
DB25 Male Terminal (Tally Station Side): Connects directly into the master parallel tally input matrix on the back of the Hollyland Wireless Tally Station box.
-
HDB15 Female Terminal (Switcher/Breakout Side): Features a High-Density 15-pin (three rows of 5 pins) D-Sub connector layout. This terminal footprint accepts a matching male HDB15 cable run or custom breakout wiring harness coming directly from your broadcast console or hardware control unit.
-
A Note on DB15 vs. HDB15: Standard DB15 connectors use two rows of pins. This cable uses an HDB15 layout featuring three rows of pins (matching the physical dimensions of a traditional VGA port style) to safely handle dense multi-channel signaling within a compact connector head.
Core Hardware & Signal Routing Features
-
Parallel Open/Closed Loop Pass-Through: Built to pass low-voltage analog ground closures smoothly. It ensures that when your control desk switches a camera to Program (Live) or Preview, the signal registers instantaneously at the Tally Station for lag-free wireless transmission to your on-camera lamps.
-
Secure Thumb-Screw Strain Relief: Designed with heavy-duty molded PVC connector heads equipped with integrated metal thumbscrews on both ends. This locks the cable tightly into the production rack, entirely eliminating loose connections caused by vibrations or accidental cable pulls.
-
Pure Copper Foil Shielding: Wrapped inside an internal RF/EMI high-density shielding layer to protect your analog signaling lanes from interference caused by heavy-duty video servers, multi-screen monitor walls, or power lines nearby.

Pin Layout Safety Warning: Never force a standard 2-row DB15 plug into the female end of this cable. Attempting to force different formats together will permanently bend the connection nodes. Always verify your video switcher's technical manual explicitly calls for a High-Density (3-row) HDB15 connection before deploying the HL-TCB07 behind your tech deck.
