One of the serial ports (I/O 2) may also be used as a local command port, for configuration or checking
on the status of the device. “Local Command Port Mode” may be entered by using either a push-button
located on the front panel of the SAG or by entering a pre-defined escape sequence on the serial port
itself. This local command port is especially useful when performing static allocation of network IP
addresses, in which case the SAG needs to be configured with an IP address prior to it its use on the
network.
An Events file is maintained by the SAG which contains logged events, such as received alarm
records, etc. Each type of item which may be recorded in the events log, is enabled by its own
configuration setting, so that the events file usage can be customized as appropriate for the installation
site.
All settings and configurations of the SAG may be made remotely, using either commands via a
TCP/IP or modem connection, or by SNMP. The SAG contains a customized management information
base (MIB) which may be used to configure and control the SAG. Configuration settings are stored in
non-volatile memory for preservation in the event of a power loss.
When used with the M-DACS the SAG module connects to the remote port of the IMUX using port 1.
Port 2 is used as a craft interface to both the M-DACS and SAG. A serial cable is supplied for
connection from I/O 1 to the RS-232 port on the MA-235. The power for the gateway is supplied via the
M-DACS motherboard.
The unit is programmed at the factory for the proper setup for most M-DACS applications. The only
required setup by the user is to program in the proper IP address for the gateway and the destination IP
address for the SNMP traps.
