The DigiSlim ST-1W1A/1F-2S 1-Ch Video, 1-Ch Audio and 1-Ch Bi-directional RS-422 Manchester Data Multimode Transmitter Card from Meridian Technologies incorporates digital encoding technology. This fiber-optic module transmits one channel of NTSC/PAL Video (10-bit, 7 MHz), one bi-directional RS-422, Manchester, bi-phase data, one channel of audio (600 Ω balanced-standard) over one fiber.
The ST-1W1A/1F-2S card is fully compatible with PC based SpectraSmart Network Management & Diagnostic Software System. SpectraSmart supervises the operating parameters of the transmission system such as the status on video levels, sync, digital carrier detect, voltages, temperatures, optical levels etc.
