8.2. Local Computer
For continuous, on-site display of battery information, use a Local computer. You can use a
Local computer with a Central computer. A Local computer performs most Central computer
functions, except that only a Central computer can permanently remove data from monitor
memory.
If a Local computer is set up as a workstation, it will clear the data in the hardware after
extraction. If you are using a Local computer as a workstation, there is no need for a Central
computer to extract the data.
MPM CAUTION: The MPM front panel Local Port switch enables the front RS-232 port or
optional rear RS-232 port, fiber optic port or LAN port. The front port is for servicing only.
When the switch is lit, the front port is selected. Use the rear port for connecting to a
permanent Local computer, Service computer or on-site Central computer. Use the front port
for using a computer for servicing. For example, if the MPM is not near the Local computer,
you may need an on-site connection for calibration or troubleshooting.
BDS CAUTION: A BDS front panel switch can disable the rear RS-232 Local port or the
fiber optic port. Select the Local position to use the front Local port. When the switch is lit,
the front Local port is selected. Be sure to select the rear Local port after use to re-establish
connection to the Local computer.
The BMDM program on a Local and Central computer is the same, except it is set for Local
rather than Central to implement special data handling when connected to a monitor.
A Local computer can be set up as a workstation and assigned a workstation name.
Select Local Computer when you want to:
Connect a computer to a monitor to continuously view monitor and battery status on-site. If
you want to assign a workstation name to the computer for use with SQL, select Local
computer.
A Local computer can do the following:
Set alarm parameters and test intervals.
Calibrate a monitor.
Collect data manually and automatically without permanently removing the data from
monitor memory.
Report string and monitor status automatically.
Upon an alarm occurrence, page personnel, fax or email a report, and sound an alarm.
Note When no network is available, a serial multiplexer is required when using more than
one monitor.
