Table 1. Right view—3001Describes the ports at the right of the Edge Gateway.
Features
1RS-232/RS-422/RS-485 port oneConnect a RS-232/RS-422/RS-485 cable to the Edge Gateway. Provides data transfer speeds up to 1 Mbps in RS-232 mode and 12 Mbps in RS-422/RS-485 mode. The serial port mode is configurable in the BIOS.
2RS-232/RS-422/RS-485 port twoConnect a RS-232/RS-422/RS-485 cable to the Edge Gateway. Provides data transfer speeds up to 1 Mbps in RS-232 mode and 12 Mbps in RS-422/RS-485 mode. The serial port mode is configurable in the BIOS.
3USB 2.0 port 1Connect a USB enabled device. Provides data transfer speeds up to 480 Mbps.
4GPIO portConnect a GPIO enabled device or dongles.
CAUTION: This port is ESD-sensitive. An insulated GPIO connector that prevents direct ESD exposure to the I/O pins is recommended.
1 USB power is limited to 0.4 A/2 W.
