DIO_BNC is an extension module (EEM) supplying 8 digital IOs via front-panel BNCs.
Design files (schematics, PCB layouts, BOMs) can be found at DIO_BNC/Releases.
- Occupies one EEM port
- Two banks of four channels each
- Each bank with individual ground isolation
- Per-bank switchable direction via on-board switches or I2C
- Per-channel switchable 50 Ohm termination with LED indicators
- Output channels can supply >2V into 50 Ohm loads
- Output channel impedance: 50 Ohm
- Short circuit tolerance: infinite
- Minimum pulse width: 3ns
- Max 150 MHz toggle rate with 50% duty cycle
- input range: -0.5V...5.5V
- output range: according to SN74BCT25245DW datasheet
- IO direction switched in groups of 4 channels
- Panel width: 8HP
If MCX connectors are preferred over BNC then the MCX_BNC_adapter adaptor can be used. This can be installed during manufacture or the conversion can be done by the user. The MCX connectors allow use of a 4HP panel instead of the 8HP required for BNCs.
