9.0 Software & Interface
9.1 Power Monitoring Software
UPSMON software (or other power monitoring software) utilizes a standard
RS-232 interface to perform monitoring functions and an orderly shutdown of
the protected equipment in the event of power failure. UPSMON displays all the
diagnostic symptoms on the monitor, including voltage, frequency, and battery
levels. UPSMON is available for Windows applications and other OS compatible
solutions. Please contact SolaHD Technical Support for more information.
9.2 Interface Kits
(optional)
Interface kits include a required interface cable to convert status signals from the
UPS into signals which an individual operating system will recognize. The inter-
face cable must be connected to the Remote Port on the rear panel of the UPS
and to the host computer (either COM 1 or COM 2). Refer to the “READ.ME” file
for further instructions.
9.3 Remote Port
(computer interface)
The Remote Port on the rear panel of the UPS may be connected to a host
computer to allow for UPS status monitoring and operation control. Functions
include: broadcasting a warning when power fails, closing any open file before
the batteries are exhausted, and turning off the UPS.
TABLE 2: REMOTE PORT PIN CONFIGURATIONS
PIN SIGNALS DESCRIPTION
2 Transmitted data (TD) RS-232
3
Received data (RD) RS-232 remote shutdown. The UPS will shut down when a high RS-232 level is
sustained on PIN 3 for 0.5 seconds. NOTE: This feature is not applicable for Models S1K320 &
S1K520.
4 Data terminal ready (DTR) +12 V
5
Signal ground
6
Ac failure. PIN 6 generates a high to low signal when there is an input line failure. PIN 6 is an open
collector output that must be pulled up to a common referenced supply no greater than +40 V dc.
The transistors are capable of a maximum load of 25 mA; only PIN 5 can be used as the common.
NOTE: Models S1K320 and S1K520 are designed without open collector signals.
7 Request to send (RTS) -12 V
8
Battery low. PIN 8 generates a high to low signal when the internal battery of the UPS has less than
5 minutes of backup time remaining. PIN 8 is an open collector output that must be pulled up to a
common referenced supply no greater than +40 V dc. The transistors are capable of a maximum
load of 25 mA; only PIN 5 can be used as the common. NOTE: Models S1K320 and S1K520 are
designed without open collector signals.
9 Transmitted data (TD) RS-232
NOTES
( 1) Switch rating is +40 V dc, 25 mA non-inductive. (2) PIN 5 should be connected to signal ground only.
(3) Models S1K650, S1K850, S1K1200, and S1K1500 provide open collector signals.
