Masterclock Countdown and Count-Up Timers
RC600
RC600 - Count Controller
RC600 — product demo (YouTube)
The RC600 is a single-channel count controller that supports counting up or down up to 99 hours, with reference time from NTP, IRIG-B or SMPTE. Output via NTP or SMPTE timecode, so the RC600 drives both NTDS and TCDS displays. Operation via front panel, network or optional GPIO contacts. The typical choice for production studios, sports halls, places of worship or meeting rooms that need one central countdown function alongside their existing time system.

Frequently asked questions
Which NTDS or TCDS displays can the RC600 drive?
All Masterclock displays that accept NTP or SMPTE input. NTDS models work via network packets (count mode); TCDS models via SMPTE timecode. A single RC600 can drive multiple displays in parallel via network broadcast.
Up to what duration can the RC600 count down?
Up to 99 hours, in 1-second resolution. For frame-rate resolution (MM:SS:FF) the RC1000 is the right model.
How is the RC600 physically connected?
Standard 1U rack mount (or desktop) with IEC power, Ethernet RJ45 for network, BNC for SMPTE out, and optional GPIO connections for external switches (start/stop/reset/pause). Request advice for specific GPIO wiring.
What is the lead time for this product?
Standard lead time is 8-10 weeks from Masterclock USA. Daylight bv stocks the most common references in Ghent. Contact us for current availability and any rush options.
What warranty do you get on this product?
5-year limited parts and labour warranty via Daylight bv as authorised Masterclock distributor. Carry-in for customers in the EEA, on-site available by prior arrangement. See [five-year warranty](/en/knowledge-base/five-year-warranty/).
