2.5 Communication Ports
MX RT
provides 4 communication methods.
1. The RS232 port provides communications using EATON Serial HID UPS transfer (SHUT) protocol. The SHUT
protocol is compatible with the power management applications available on the enclosed Solution-Pac 2
CD-Rom.
2. The Output contacts port is used for basic signaling or for protection of IT systems like IBM iSeries (formerly
AS400) and more.
3. The USB port is compatible with the power management applications available on the enclosed Solution-Pac
2 CD-Rom.
4. The slot is compatible with the optional 66102 — Network Management Card (NMC) 2006 Edition and the
66103-Status Card.
Note All communications options can be used simultaneously except for the SHUT RS232 and USB port. If both
the USB and SHUT ports are connected then the USB takes control.
Connection to the RS232 or USB communication port (42)
1 Connect the RS232 (42) or USB (44)
communication cable to the serial or USB
port on the computer equipment.
2. Connect the other end of the RS232 cable
(42) to the RS232 (7) communication port or
the USB cable (not included) to the USB port
(6) on the UPS.
The UPS can now communicate with various
EATON power management application
software.
Please note that Personal Solution-Pac can
be used to configure (personalize) the UPS
parameters such as voltage, frequency,
battery test, etc. See section 4.6 for more
details.
