Serial Port; Removable Data Storage Devices (Rdsds) - Emerson PACSystems RX3i Quick Start Manual

Serial Port

The CPE302 provides one RS-232 serial interface to external devices. This
port can be used for firmware upgrades. The port is electrically isolated. For
serial port pin assignments and details on serial communications, refer to
the PACSystems RX3i CPU Reference Manual, GFK-2222.
The RS-232 port does not supply the 5 VDC power offered by other RX3i
and Series 90-30 CPUs. Cable IC693CBL316 must be used for RS-232 serial
connections to the CPE302.
Removable Data Storage Devices
(RDSDs)
The CPE302 provides the ability to transfer applications to and from an
RDSD (USB compatible device, such as a memory stick, smart phone, digital
camera or MP3 device). Once the data is copied to the RDSD, it can be
written to other RX3i CPE302 CPUs with no programmer software needed.
The RDSD interface requires a user-supplied flash memory device that
complies with the USB 2.0 Specification.
The USB port must be enabled in the RX3i configuration in order to transfer
data between the CPU and the RDSD. The CPE302 is shipped with the RDSD
(USB) port enabled. Complete details of the use of RDSDs are found in the
PACSystems RX3i CPU Reference Manual, GFK-2222.
