7 interfaces over USB
======================
Multiport board
====================================
Seven isolated interfaces:
- 1 CAN
- 3 RS-485
- 2 or 1 RS-232
- 1 SSI or 1 RS-422 (in this case 1 RS-232)
- 1 SSI or 1 RS-422 (in this case only one RS-232)
Inner USB interfaces (IFx):
1..3 - RS-485 (1..3)
4 - RS-232 (1)
5 - RS-232 (2) or RS-485
6 - CAN
7 - SSI (over SPI) or configuration interface (if "Config mode" jumper shortened)
1. RS-485 (1)
2. RS-485 (2)
3. RS-485 (3)
4. RS-232 (1)
5. RS-232 (2) or RS-422 (by jumpers)
6. CAN
7. SSI (over SPI, by jumpers) or configuration interface (if "Config mode" jumper opened)
