RMS NetLinx Programmer’s Guide
All parameters must be registered by the NetLinx system. The administrator
cannot add parameters from the RMS console. The administrator can modify
Threshold Value, Comparison Operator, and Status Type for any parameter. This
provides the administrator with the ability to set their own thresholds and
re-classify messages based on their facility. For instance, an administrator can set
the Video projector's "Lamp Hours" threshold to the expected lamp life of a
newly replaced lamp or change the "Device Communicating" parameter from a
"Control System Error" to a "Security" status if the projector is in danger of being
stolen.
Parameter Values
Status Type The status represents the type of problem a faulted condition
represents. Status Types include "Help Request",
"Maintenance Request", "Room Communication Error",
"Control System Error", "Network Error", "Security", and
"Equipment Usage."
For example, when "Lamp Hours" changes from an un-faulted
(not greater than 1000) to a faulted (greater than 1000), this
change represents a "Maintenance Request" status that
requires an AV technician to repair the equipment. If the
"Device Online" parameter changes from "Online" to "Offline",
this change could represent a "Security" or "Control System
Error" status.
These value are supplied during registration but can be
modified by the administrator from the RMS server
console.
Reset Flag and Reset
Value These values determine if and how the parameter can be reset
from the RMS server console. If the Reset Flag is set, then the
administrator can reset the value remotely. When the adminis-
trator selects "Reset" from the console, the Reset Value is cop-
ied to the Value and the faulted condition is cleared. These
values are useful for parameters such as VCR "Run Time"
which would be manually reset when the VCR is cleaned.
Minimum and Maximum
Values These values are used to restrict the range of the threshold
and reset values that the administrator can enter on the
RMS server console. These values would be used when the
parameter represents a value with a bounded range, such as a
Volume Level.
Enumeration List This value is used to restrict the range of the threshold and
reset values that the administrator can enter on the
RMS server console. This value would be used when the
parameter represents a value with a bounded list, such as a
list containing the values Power On and Power Off.
