Product number: TL4K1161-PK

The TL4K1161 is a small form factor serial digital video (SDI) transmitter from AIVION. Camera video input signals are equalized, processed, and output over straight DIN7A(10.23) connectors. Dual Link 3G-SDI output compliant to SMPTE ST425-3, 2si mapping, FHD output compliant o SMPTE ST425-1 level A Camera control is accomplished by a transparent full-duplex communication channel. The physical interface between camera and camera controller / PC is based on RS232 or 3.3V TTL level. TLCK-B cable kit is included and contains a 30wire micro coaxial cable for connecting TL4K1161 to FCB-ER8300 as well as a 10wire power supply and serial control cable harness.
