Related Questions and Answers

Q: 1. Does this have any compression on it? And how much? Does this work with the blackmagic mixers?

A: Yes it does have compression. According to Hollyland their code rate is 8M-10M. For use with a production switcher you would want to look an uncompressed option like the Hollyland COSMO 600 Wireless HDMI/SDI Transmission System (L-Series) instead, BH #HOCOSMO600L.

Q: 2. What's the distance can it go

A: This has up to a 400 foot range.

Q: 3. Is this compatible with the Mars 400 Dual HDMI as well?

A: no it is not compatible with the Hollyland Mars 400 Dual HDMI Wireless Video Transmission System

Q: 4. The manual states "THE DEVICE IP IS 192.168.218.X NETWORK SEGMENT". Can that be changed? Or is it stuck on the factory subnet?

A: No, according to the manufacturer, the IP address on the Hollyland Syscom 421S 4-Transmitter 1800' A/V Transmission System cannot be changed and will remain on the default setting.

Q: 5. If I buy 3 sets of tx/rx is it possible to connect 3 receivers to one transmitter, or is it limited to two receivers per 1 transmitter?

A: This system is limited to two receivers per transmitter.

Q: 6. Latency?

A: To transmit video, the MARS 400S uses a 5Ghz frequency band, with up to 400 feet (120m) line-of-sight range. According to Hollyland, the latency is less than 0.1 second.

Q: 7. For the TX, these use a 2-pin lemo-- are we able to use Teradek 2-Pin lemo or are these pinned differently?

A: We would suggest working with the Hollyland 2-Pin 12V AC/DC Power Supply. Hollyland 2-Pin 12V AC/DC Power Supply BH #HO2PACDCPWRS

Q: 8. What kind of compression does this use, and what is the bitrate?

A: According to Hollyland their code rate is 8M-10M.

Q: 9. Is it possible to connect multiple receivers to one transmitter?

A: While that may be possible, we do not have receivers available for separate purchase at this time.

Q: 10. Can mars 400 link with mars 300?

A: We are not aware of there being cross compatibility between the 400 and 300 series. Also we only sell these products as transmitter and receiver pairs.
