Hollyland Spares - DB25 Male to Dual HDB15 Male Tally Cable (for Wireless Tally System)The Hollyland DB25 Male to Dual HDB15 Male Tally Cable (Model: HL TCB10) is an official OEM Y split adapter cable engineered for the Hollyland Wireless Tally System. This specialized interface cable bridges the gap when a professional broadcast vision switcher provides its tally contact closure outputs via a standard DB25 (25 pin D Sub) bus, while the Hollyland Wireless Tally main transmitter box utilizes high density HDB15 (15 pin D Sub) input
The Hollyland DB25 Male to Dual HDB15 Male Tally Cable (Model: HL-TCB10) is an official OEM Y-split adapter cable engineered for the Hollyland Wireless Tally System.
This specialized interface cable bridges the gap when a professional broadcast vision switcher provides its tally contact-closure outputs via a standard DB25 (25-pin D-Sub) bus, while the Hollyland Wireless Tally main transmitter box utilizes high-density HDB15 (15-pin D-Sub) input terminals.
Core Functionality & Purpose
On multi-camera live broadcast sets, matching the tally cues from a production switcher to a wireless transmitter can easily turn into a cabling nightmare. The HL-TCB10 functions as a physical breakout and converter:
-
Y-Adapter Expansion: It splits a single DB25 switcher master connector out into two separate HDB15 male terminals.
-
Dual-Port Input Routing: This layout allows you to feed a single, consolidated DB25 switcher bus straight into two separate Hollyland wireless tally input banks concurrently, enabling larger multi-camera operations (supporting up to 8 separate tally indicators) without needing custom soldering or breakdown boards.
-
OEM Pin-Out Mapping: Wired precisely to match Hollyland’s internal ground and trigger configuration frameworks, guaranteeing zero ghosting or missed red/green light triggers during high-speed switching.

Switcher Deployment Check: Before running this cable, verify your switcher's manual to confirm it uses a standard DB25 dry-contact relay loop. Because this is a direct, passive wire matrix mapping, it assumes your vision switcher completes the circuit to ground when a camera goes live. If your switcher outputs active voltage tally triggers instead of contact closures, running a direct cable can cause an electrical mismatch; double-checking your hardware configuration prevents damage on set.
