PPS TRIG IN accepts 0 V to 3.3 V TTL and 0 V to 5 V TTL signals. You can also use this port as a triggered input (TRIG IN) that you control using software. | ||||||||
| 06) PWR | DC power connector (M) and indicator light. | ||||||||
| 07) DP | DisplayPort connector to connect one monitor for your controller. | ||||||||
| 08) USB | USB3.0 Type-A ports that support common USB peripheral devices such as flash drives, hard drives, keyboards, and mice. | ||||||||
| 09) RJ45 | RJ45 port used for 1G ETH connectivity to other ethernet devices. | ||||||||
| 10) OTG | Type-C port that supports USB3.0 peripheral devices and reaches to 5Gbps Data Transfer Rate. The port is compatible with data protocol OTG 2.0/3.0. | ||||||||
