Hollyland Spares - DB25 Male to DB15 Male Tally Cable (for Wireless Tally System)

The Hollyland DB25 Male to DB15 Male Tally Cable (Model: HL-TCB02) is an official OEM interface adapter configured specifically for the Hollyland Wireless Tally System.

While the standard DB15 female variant maps incoming auxiliary breakout wiring harnesses, this DB15 Male configuration serves as a direct device-to-device connector. It links the parallel tally output framework of native broadcast hardware straight into the main database tracking array of your Hollyland Wireless Tally Station box.

Understanding the Physical Pin Form Factors

• DB25 Male Terminal (Tally Station Side): Connects firmly into the 25-pin female parallel matrix terminal block mounted on the back panel of the master Wireless Tally base station.

• DB15 Male Terminal (Switcher Output Side): Features a standard-density 15-pin profile arranged in 2 rows (8 pins over 7 pins) with outward-facing pins. It plugs directly into video switchers featuring native female DB15 parallel tally outputs without the need for an intermediate adapter or gender changer.

Core Hardware & Signal Routing Features

• Low-Voltage Parallel Relay Mapping: Built to carry low-voltage dry contact relay closures without operational lag. The millisecond the master video switcher toggles a line to Program (Live) or Preview (Next Up), the specific circuit completing through the HL-TCB02 cable path alerts the base station to update your remote camera lamp colors.

• Direct Switcher Compatibility: Specifically engineered to bridge communication protocols natively with well-known broadcast hardware utilizing this exact output profile—such as select Panasonic AW-HSW10 or Panasonic AV-HS410MC vision mixers.

• Industrial Strain Relief & Shielding: Fabricated with heavy-duty molded PVC connector backshells equipped with captive thumb-locking screw sets to lock into place behind tight, high-traffic tech decks. The core is protected with premium foil shielding to keep parallel data paths isolated from adjacent electromagnetic interference (EMI) radiating from studio power grids or server clusters.

Technical Specifications Matrix

The 2-Row vs. 3-Row Density Rule: Always double-check the configuration of your production switcher's tally out block before seating the cable. A standard DB15 Male (this product) features a wider shell framing 2 rows of pins. A high-density HDB15 model features a tighter footprint with 3 rows of micro-pins (styled like a legacy VGA monitor hookup). Forcing incorrect pin row densities together will permanently crush the copper contacts.
