Ethernet Ports
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45
connectors. Refer to the following table for the pin assignments.
Serial Ports
The two serial ports (P1 and P2) use terminal connectors. Each port can
be configured by software for RS-232, RS-422, or RS-485. Refer to the
following table for the pin assignments.
SD/SIM Card Slots
The UC-8100 comes with an SD slot for storage expansion and a SIM card
slot for cellular communication. The SD card/SIM card slots are located at
the lower part of the front panel. To install them, remove the screw and
the cover to access the slots, and then insert the SD card or the SIM card.
You will hear a click when they are inserted correctly. To remove them,
