    1.3. Functional Description The CLT-302L & CLT-302R Camera Link Translators enable the use of traditional RS- 422 and LVDS digital cameras with Camera Link frame grabbers. Block diagrams of the CLT-302R and CLT-302L are provided in Figures 1-1 and 1-2, respectively. The CLT- 302R is intended for use with RS-422 digital cameras and the CLT-302L for use with LVDS (EIA-644) digital cameras.

  • Page 9 The CLT-302 receives parallel digital camera data on the 100-pin camera connector and maps the pixel data into the corresponding Camera Link “base” configuration format. The CLT supports single-channel (monochrome) cameras with 8/10/12/14/16-bit pixels, dual- channel 8/10/12-bit cameras, and 8-bit color cameras. The latency (i.e.

  • Page 11 The CLT-302 is powered by an external wall plug-in power supply. A multi-nation power supply is standard. Optionally, the CLT-302 is available with a locking power supply connector. The locking power supply connector reduces the risk of accidental disconnection. The CLT-302 is also available without any power supply for customers who want to provide their own power source.
