Default Access Level: This setting determines the level of access a user will have if they open the
web page without logging-in to the system. The most secure setting is “Login Required” which
means a user cannot view or change anything in the system without first logging-in. There are also
two read-only modes: Status-View and User-View.
Status View: The status-only user can view the current status of the system without being able to
view the programming. For example, a status only user could see that an input was 75ºF, but not
know the calibration value (º offset) or the low/high limits for the sensor.
User View: The basic user has access to view the system without making any changes. The user
shall be able to view programming without being able to change it.
The last option is to completely disable security which gives anyone full programming capability
without logging-in to the system.
Configuration Password: The network configuration screen is password protected. The password
can be changed by clicking the “change password” box and entering a new password in the boxes
provided.
SNMP Agent Settings: The IMS-1000 contains an SNMP agent which allows read and write access
to most of the IMS-1000 parameters from an SNMP console. To enable the SNMP agent click in
the Enable box. You must also configure the Read-Only and Read-Write Community Strings. The
default settings for these are “public” (Read-Only) and “private” (Read-Write), which are very
common and should be changed for security purposes.
Battery Maintenance
The IMS-1000 includes an internal UPS that automatically switches to battery backup in the event
of an AC power failure. The battery in the IMS-1000 is a 6V 3.4AH sealed lead acid. This battery
will keep the unit operating for approximately 3.5 hours when fully charged and under normal oper-
ating conditions.
Service life
Over time and with periodic use, the battery will begin to lose its capacity, resulting in less overall
backup time. Under normal operating conditions, three or four years of dependable service life can
be expected or between 200 and 1000 charge/discharge cycles, depending on the average depth
of discharge. Eventually, battery replacement will be required to maintain a dependable level of
service.

The battery can be replaced by following the instructions listed below. Be sure to read all safety
messages and follow the instructions in order as listed. Several tools will be required to change the
