SWIT Electronics S-4903R - Manual (Page 4)

1. Product Introduction
This broadcast industry wireless system includes S-4903T transmitter and S-4903R receiver, adopts WHDI
(OFDM) technology, supports uncompressed 3G/HD-SDI wirelessly transmitted in 200 meters scale, and with
less than 1ms latency, which is widely used in on-site shooting and director monitoring.
2. Features
◆ ◆ ◆ ◆ Uncompressed 3Gb/s SDI transmission
Support up to 1080p 50/60 uncompressed SDI wireless transmission
◆ ◆ ◆ ◆ 200 meters transmission distance
In open outdoor area, the effective transmission distance is approx 200 meters.
◆ ◆ ◆ ◆ Less than 1ms latency
There’s no discernible video delay and you can use it as real time on-location monitoring.
◆ ◆ ◆ ◆ License free operation frequency
The wireless frequency is 5.1-5.9GHz, license free operated.
◆ ◆ ◆ ◆ Transmitting frequencies
The system will auto select from 4-ch frequencies, to ensure the effective transmission. In the same
location, it supports 4-pair transmissions at most.
◆ ◆ ◆ ◆ SDI embedded audio transmission

Remark:
1. The transmission distance may be different, and depend on surroundings, radio wave conditions, buildings,
etc., the 200 meters transmission distance may be not guaranteed.
2. The wireless transmission might be interrupt if there’re many other devices of 5GHz wireless bandwidth
operated in the in the same location.
3. Signal reception may be affected by the position, height and angle of devices. If reception video is not stable,
please physically adjust placement for the optimized signal.
4. Set the antennas at 45° to each other will enhance the transmission efficiency.
5. The product offers the AES 128-bit encryption to protect the wireless transmission. Anyway, please be ware
of the intentional capture from third person.
