Galaxy Vector Controller GCM2, GCM3
Issue 4 January 2008 Operation 3 - 19
The Vector controller provides one remote access port. It may be
accessed remotely or from a terminal device. The port interfaces
with either the remote access interface card (BSM3) that
provides modem and RS-232 access, or with the Gateway card
(EBW1) for TCP/IP access. See Appendix A.
Once logged into the controller, users type in commands to
access measurements, configuration and control parameters in
the system. The command line interface used for incoming
connections is a version of T1.317 adapted for low end
controllers. Two levels of security, User and Super-user, are
provided to protect incoming access and to prevent any
unauthorized access.
The controller can be configured to dial out on alarm and dial out
when all alarms are cleared using the internal modem. The port
settings, configuration and command language used for remote
access as well as the error messages is described in the
Appendices A and B.
Remote Rectifier
Standby
The rectifiers can be placed in standby after accessing them
through the local port or through a modem. Once the rectifier is
placed in standby, it automatically recovers from this state when
the plant voltage drops below the BD threshold level, when the
active rectifiers cannot supply the plant demand.
Dial-out On
Alarm
This function requires the optional BSM3 modem card. See
Appendix A for description. By default, the controller is
configured not to dial-out at all. It can be configured to dial-out
to a primary phone number or an alternate phone number, used
if the controller fails connect to the primary phone number. The
controller attempts to dial-out when an alarm occurs that it has
not reported yet and when all alarms clear.
Phone numbers may be up to 25 characters long and may contain
any of the following characters: 0123456789,( )#* or space.
Configuring the phone numbers enables the controller to dial-
out. The phone number must be the number of a modem. After
the controller connects to the remote modem it sends an alarm
report. The alarm report is the same report generated by the
T1.317 “ala” command with addition of the site id at the
beginning of the report.
