EATON RS232 Minislot Management Card Contacts
INTRODUCTION
The Management Card Contact & RS232/Serial offers two types of interfaces via a DB9 connector
- Dry contacts (contact mode)
- RS232 serial interface (RS232 mode)
All UPSs from EATON equipped with a Minislot can be connected to a number of electrical-management applications. Jumpers are used to select the interface (contacts or RS232).
APPLICATIONS
Contact mode (factory setting)
-
In this mode, the card provides a simple way to remote UPS information to an alarm system, PLC or computer system via dry contacts (relay).
The transmitted information is load powered, load on bypass, load on battery , load on utility, battery fault and low battery. -
A UPS power off function activated by an external contact or voltage level is also proposed. It is available only in contact mode.
-
Equipped with an IBM iSeries (66033) or Windows (66047) cable available from EATON, the card offers direct communication with the power-management system of the servers supplied by the UPS and can thus provide protection (shutdown) on reception of one of the information signals. Configuration of the various systems is presented in the documents supplied with the cable. For this application, use the Config2 setting on the card.
RS232 mode
- In this mode, the card offers an RS232 interface for connection to a PC or to a UPS Control display unit. Connection to a PC requires the RS232 UPS Communication Cable (66049). The cable is not supplied with the card. Once connected the protection software can be installed and used immediately.
- The WindowsTM Plug&Play function is managed by the card.
- The cable and the display are available from EATON.
UNPACKING AND CHECKS
- One Management Card Contact & RS232/Serial
- One installation manual (34003907)
OVERVIEW
CONTACT MODE CONFIGURATION
- In this mode, the contact (relay) is closed between the common (pin 5) and the pin transmitting the signal (pin 2, 4, 6, 7, 8, 9) when UPS information is active or true.
- When the card is not supplied, all the contacts between pin 5 and the other pins are open, except the contact between pin 4 and pin 5, which remains closed.
- Three configurations are available in this mode, for three types of UPS power off. The diagram below shows, for each configuration, the jumper settings, the various contacts (card not supplied) and the external wiring for the power off function. The UPS shuts off if the contact position is the opposite of that shown.
DB9 CONNECTOR PINOUTS
- The function of this pin varies, depending on the configuration. The Battery fault information is available only in Config 2.
- Load on utility and Load on battery are complementary signals. They cannot be activated simultaneously.
- Not available on line-interactive UPS. No manual bypass.
RS232 MODE CONFIGURATION
- In this mode, only one configuration is possible.

- Remove the plastic cover of the Minislot.
- Insert and secure the card with the screws.
