SL4651 is a small form factor HD-TVI/AHD analog HD video transmitter for Block Cameras. Camera LVDS video input signals are demultiplexed, processed and output over a MCX coaxial connector. Camera control is accomplished by a transparent full duplex communication channel. Physical interface between camera and camera controller / PC is based on RS232, 3.3V TTL or RS485(optional) level. TLCK-B-0200 cable kit is included and contains 30wire micro coaxial cable for connecting SL4651 to the camera as well as 10wire power supply and serial control cable harness.

Onboard Mode Switch:
Switch #1 SL4651 Video Output Mode: OFF=HD-TVI, ON=AHD
Switch #2
Camera Monitoring Mode Adjust: OFF=No change, ON*=Force 1080p30 *SL4651 onbaord microcontroller adjusts camera video output setting to 1080p30 if switch #2 is in ON position. Checking switch #2 is done once during SL4651
boot cycle. Changing switch #2 position during board operation has no effect. Also switch #1 must be preset before power is applied to SL4651.
