МТ3921 (МТ3921S)
Digital I/O
MT3921 - 3U 2 to 1 DVI switch with digital I/O. The MT3921 is standard 3U single-width (4HP) module gives the convenience of sharing 2 DVI source devices with one display. The DVI-D interface supporting 165MHz speed operation all video formats up to 1080p and SXGA (1280 x 1024 at 75Hz).
The MT3921 is standard 3U single-width (4HP) module gives the convenience of sharing 2 DVI source devices with one display. The DVI-D interface supporting 165MHz speed operation all video formats up to 1080p and SXGA (1280 x 1024 at 75Hz). It is designed for very low cross-talk, low bit-to-bitskew, high channel-to-channel noise isolation and low I/O capacitance.
The DVI-D available on two connectors at front panel.
The MT3921 has 12 24V digital inputs isolated from the computer system by optocoupler galvanically. The inputs are also potential free to each other in groups of four inputs. A high performance of input circuit ensures a defined switching point and polarization protection against confusing the pole. All inputs have a common electronic debounce circuit with a debounce time freely programmable .
The MT3921 has 12 digital high side switches with galvanic isolation from the computer system by optocoupler.
The outputs are also isolated against each other in groups of four outputs. All outputs are protected against shortcircuit and thermal overload. The output drivers are capable of driving 0.5A per channel continuous. A hardware watchdog clears all outputs in case of trigger fail.
The MT3921 has 8 digital TTL inputs/outputs. Two USB 2.0 are placed on the board in addition. All I/O available on the J2 rear I/O connector.
