USB Port

CPE100 has one USB Port located on top of the front panel, but currently it is disabled
for security reasons.

Serial Ports

CPE100 supports both the RS-232 and RS-485 ports. RS-485 port supports only two
modes of operations 2-Wire and 4-Wire. These ports are located on the underside of
the controller (Figure 5). No isolation is provided.
Recommendation: use any suitable commercial off-the-shelf device if an application
requires isolation.
