2-18 Connecting the Cables FCD-E1
Connecting the Management Ports
This section provides information on the management connections.
FCD-E1 has one supervisory port, CONTROL DCE, located on the front panel, and
a dial-out port for connection to modems, CONTROL DTE, located on the rear
panel.
Connecting the CONTROL DCE Port
The front panel CONTROL DCE supervisory port has a 9-pin D-type female
connector with RS-232 interface. The interface (DCE or DTE) is software
selectable. The default selection, DCE, enables direct connection to terminals and
management stations; when the supervision terminal or management station is
connected via modems, LAN extenders, or similar equipment with DCE interfaces
(the interface is configured as DTE), it is necessary to use a crossed adapter cable.
Appendix A provides the pin allocation for the connector.
Connecting the CONTROL DTE Port
This connector is intended for connection to a modem or low-speed multiplexer
link, for communicating with remotely located supervisory terminals, management
stations, etc. Use a straight cable to connect to a modem. You may also use a
dial-up modem, configured for auto-answer and preprogrammed to dial the
desired number, to automatically report alarms to a central location.
Appendix A provides the pin allocation for the connector.
Connecting the Alarm Relay
When the alarm relay is in use (Jumpers JP51 and JP52 set to RELAY), its contacts
are available in the CONTROL DTE connector, and you can connect them as
described in Appendix A to automatically turn on a bay alarm indication. The use
of the alarm relay does not prevent the connection of a modem to the CONTROL
DTE connector.
Connecting the Power
To connect the power to FCD-E1, refer to the appropriate section below,
depending on your version of the unit (AC or DC).
Before connecting any other cables and before switching on this instrument,
this instrument must be connected to the protective ground. The connection is
made through the protective ground conductor of power cord. The power plug
shall only be inserted in a power outlet provided with a protective earth
contact. The protective action must not be negated by use of an extension cord
(power cable) without a protective conductor (grounding).
Make sure that only fuses with the required rated current, as marked on the
FCD-E1 rear panel, are used for replacement. The use of repaired fuses and
the short-circuiting of fuse holders are forbidden.
Whenever it is likely that the protection offered by fuses has been impaired,
the instrument must be made inoperative and be secured against any
unintended operation.
