1.1 Overview
Figure 1-1: FLEX-BX100-ULT5 Series Box PC
The FLEX-BX100-ULT5 box PC is powered by 8th Generation Intel® Core™ i5-8365UE /
Celeron®4305UE Processor which is a System-on-Chip (SoC) that ensures optimal
memory, graphics, and peripheral I/O support. The system comes with 4.0 GB of DDR4
SO-DIMM memory ensuring smooth data throughputs with reduced bottlenecks and fast
system access.
One RS-232/422/485 serial port, one RS-232 serial port and four external USB 3.2 Gen 2
ports ensure simplified connectivity to a variety of external peripheral devices. Three
RJ-45 Ethernet connectors provide the system with smooth connection to an external
LAN. Moreover, two of the Ethernet connectors are capable to support PoE by installing
the optional PoE module.
