3-in-1 Combo Cable
The combo cable includes the following connectors:
An RS232 connector to link to the host terminal COM port enabling use of the
monitor utility
A modem connector enabling the automatic dispatch of alert faxes
A monitor connector enabling various monitoring facilities. The default pin
assignments are:
Pins 1+3: Fan failure
Pins 2+4: Temperature failure
Pins 5+7: Power source failure

RS232 Connection for VT-100/ANSI Terminal-Emulation
The ACS-8990 controller can be configured via a PC running a VT-100 or ANSI
terminal-emulation. In order to connect to a PC, you may need to connect an additional
interface cable to the combo cable, which converts the RS-232 signal of the 10-pin header
connector into a 9-pin D-sub male connector. The pin-layout of the 9-pin D-sub male
connector is similar to that of a PC's serial power and is set as a DTE device.
Default Serial Port Settings
The baud rate can be changed using the interface on the front panel.
Modem Connection
ACS-8990 can be connected to a modem to allow remote notification in the event of an error.
If a modem is properly connected to the modem header of the combo cable, you can
configure the ACS-8990 to notify the administrator in case of malfunction. Supported
notification devices are fax and pager.
