Usb Port; Serial Ports - Emerson PACSystems RSTi-EP Quick Start Manual

USB Port

CPE115 has one USB Port located on top of the front panel. It is currently disabled. As
a result, CPE115 does not support Remote Device Storage Device (RDSD).

Serial Ports

CPE115 provides both RS-232 and RS-485 ports. RS-485 port supports two modes of
operation: 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.
