The Hollyland BMD Tally Cable (Model: HL-TC02) is an official OEM interface adapter specifically designed to link Blackmagic Design (BMD) hardware infrastructures to Hollyland’s legacy full-duplex wireless intercom stations, namely the SYSCOM 1000T and the MARS T1000.
While Hollyland’s newer dedicated Tally base stations use the TCB cable family, the HL-TC02 is engineered specifically for the specialized auxiliary IO tally ports found on the back of the Syscom and Mars intercom master stations to pull native tally logic directly from Blackmagic setups.
System Ecosystem Interoperability
This specialized patch cable bridges Blackmagic's automated tally output hardware with your wireless floor-comms network:
-
Hollyland Base Stations: Mars T1000 Master Station & Syscom 1000T Base Station.
-
Blackmagic Design Integration: Connects directly to the Blackmagic Design GPI & Tally Interface breakout box (which converts Ethernet commands from ATEM switchers like the ATEM 1 M/E, 2 M/E, or Constellation series into dry-contact closures).
Core Hardware Features
-
Dedicated Comm-to-Switcher Interface: Purpose-built pin mapping that links the intercom master station directly to the D-Sub port of the BMD GPI unit. This ensures that when the ATEM video switcher flips a camera channel live, the red/green camera cues immediately transfer over the 1.9GHz wireless frequency to the beltpacks' attached tally indicators.
-
Molded Strain Relief Boots: Features industrial-grade molded PVC backshells with integrated thumb-locking screw sets. This locks the interface tightly into your desktop engineering console or portable production fly-pack, preventing dropouts from cable tension or rack vibrations.
-
High-Density Copper Core & EMI Shielding: Armed with a dense internal shield layer to isolate low-voltage signaling lines from electromagnetic interference (EMI) radiating from close contact with heavy-duty video routers, multi-viewers, and studio power loops.

On-Set Setup Architecture Tip: Remember that this cable cannot plug directly into the back of an ATEM switcher's ethernet or HDMI/SDI ports. To use the HL-TC02, you must route your ATEM switcher to your control network, connect the Blackmagic Design GPI & Tally Interface box to that same network via RJ45, and then use this HL-TC02 cable to bridge that interface box directly to the Hollyland Intercom Base Station.
