UPS with "Protocol Interface"
(option)
This option converts Basic type
information into the RS232 serial
protocol. It is then possible to use the
administration and system shutdown
capabilities of Solution Pac software.
MultiSlot (optional)
When the MultiSlot option is installed,
the STS and the two UPSs act as a one.
MultiSlot, equipped with two MetaUPS
acquisition cards, concentrates the data
coming from the U-Talk ports on the
UPSs and from the STS COM port on
STS. Communication with the protected
systems is optimized through use of a
U-Talk, J-Bus or SNMP card.
In this case, the protected application will
shutdown only when all available energy
has disappeared, i.e. the batteries on
both UPSs have been depleted. See the
MultiSlot user manual for information on
connections.
STS COM communication
This communications port 13 supplies
status information on STS.
