Product number: TL4K1261-PK
Manufacturer: AIVION

The TL4K1261 is a small form factor serial digital video (SDI) transmitter from AIVION with Power and Control over Coaxial Cable. 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 TL4K1261 to FCB-ER8300 as well as a 10wire power supply and serial control cable harness.
