Product number: TL4K1171-PK

The TL4K1171 is a small form factor serial digital video (SDI) transmitter from AIVION. Camera video input signals are equalized, processed, and output over coaxial connectors. 6G-SDI output is compliant to SMPTE ST2081-10 MODE 1 mapping, Dual Link 3G-SDI output is compliant to SMPTE ST425-3, 2si mapping and 3G-SDI FHD output is compliant to SMPTE ST425-1 level A standards. Camera control is accomplished by a transparent full duplex communication channel. Physical interface between camera and camera controller / PC is based on RS232 or 3.3V TTL level. TLCK-B cable kit is available as accessory.
