Installation and Operation Manual Chapter 3 Operation
FCD-E1 Configuration Alternatives 3-9
For multidrop operation, each FCD-E1 system must be assigned a node address in
the range of 1 through 255.
FCD-E1 systems also support address 0: assigning address 0 to a FCD-E1 system
means that it will accept and answer any message: this is not permitted in
multidrop operation. Address 0 is however recommended for use both with direct
connections, and point-to-point or dial-up modem links.
In addition, each FCD-E1 can be assigned a logical name of up to eight characters.
The logical name is sent in each transmission of alarm messages. The name helps
the operator to identify the source of messages that are received by the supervision
terminal.
Connecting Alarm Monitoring Terminals
FCD-E1 systems support automatic reporting of alarms to remote terminals. This
function is supported through the rear panel CONTROL DTE port (the CONTROL
DTE port does not support supervision terminals).
Generally, the alarm-monitoring terminal is connected to the CONTROL DTE port
of an FCD-E1 system through a dial-up modem link.
CONTROL DTE ports are located only on all FCD-E1 versions. The CONTROL DTE
port has a standard RS-232 asynchronous interface.
CONTROL Port Interface Characteristics
The CONTROL DTE port supports the following data rates: 300, 1200, 2400,
4800, 9600 or 19200 bps. The CONTROL DTE port does not support the
AUTOBAUD function.
The data rate used by the CONTROL DTE port is always equal to the data rate
configured by the user. It need not be equal to the data rate used at the CONTROL
DCE port.
The word format consists of one start bit, 7 or 8 data bits, and one stop bit. Parity
can be odd, even or disabled. Always make sure the communication interfaces of
the equipment (e.g., dial-up modems, etc.) connected to the CONTROL DTE port
and the port itself are configured for operation with the same parameters.
Connection of Dial-Up Modem
If you are using a dial-up modem, connect a straight cable from the modem to the
CONTROL DTE connector of the FCD-E1.
Connecting Telnet Hosts
The Telnet protocol enables communication with multiple FCD-E1 system units,
using either inband or out-of-band communication:
• For communicating out-of-band, the Telnet host must be connected to the to
the serial port of the FCD-E1 system.
• For inband communication, the user can enable the transfer of management
traffic through the main and/or sublinks.
