Using coaxial cables with very low power loss, enables video transmission over 100 meters. This distance can be increased up to 300 meters using equalization at the receiver. Twiga 3G-SDI Premium converts the native LVDS video signal from camera blocks to 3G-SDI. It takes advantage of a high quality, low jitter and uncompressed SDI stream.

TV10 0090_3G-SDI Premium Interface board_Preliminary TV10 00 7/10 System configuration Communication Communication with the camera can be done through J4 with the following pins: o RX o TX o GND Communication can be set to either RS232 mode (according to EIA RS-232 specification) or TTL mode (UART with 3.3V compatibility).
TV10 0090_3G-SDI Premium Interface board_Preliminary TV10 00 8/10 Switches: communication and video format 4 DIP switches are available. Switch 1: to select the communication standard between RS232 and TTL. Switch 2- 3- 4: to select the video format. The board checks, when the camera power is on, if the camera video format corresponds to the switches, otherwise it sends a VISCA command to change the format.
