3.7 TDI Length Selection
TDI length selection for the 2K/4KTDI LVDS camera can be selected using the combination of TDISEL0 and TDISEL1 input signal into the DB15 control connector.
The TDISEL0 and TDISEL1 are LVDS level signals. They are typically wired to the user control I/O of the frame grabber.

TDI LENGTH | TDISEL1 | TDISEL0 |
96 | HIGH | HIGH (Default Setting) |
