12.1.2 Configuring the Liebert STS2 via the Terminal
The SPT command is used to configure the systems setpoints. The SVT syntax for the setpoints con-
sists for four parameters:
SPT [group] [item] [value]
where the parameters are:
• SPT — is the terminal command that is used to configure setpoints.
• group — the group under the setpoint command which contains the desired settings.
• item — the item number within the selected group.
• value — the desired value for this item.
Only the specific options words listed in this section use a hexadecimal value. Other settings, depend-
ing on what they are, use other input types. For example, System ID uses a text string, nominal volt-
ages and currents use standard numeric integers, and modem baud rate uses an enumeration where
0 = 2400, 1 = 9600, & 2 = 19200 bps.
This section provides instructions for setting these parameters, with an example of building an SPT
command for System and User settings.
Groups Parameter
The setpoints are grouped for ease of configuration. For example, Event Masks are Group 4 and Sys-
tem Settings are Group 2. The numbers shown below are entered for the group parameter. For exam-
ple, start of a System Settings command is SPT 2.
The group parameters are:
1 = System Ratings
2 = System Settings
3 = User Settings
4 = Event Mask Settings
For example, the start of a System Settings command is SPT 2, where SPT is the system setpoints
command and 2 is the group parameter for System Settings.
See 12.1.4 - Setting Event Masks with the Terminal on page 83 for instructions on configuring
Event Mask parameters.
Item Parameter
Each setting within the group is indexed by an item number as shown below in Table 11. These item
numbers are also displayed on the terminal when you list the configuration setting for a particular
group.
Continuing with the example, to configure an Options_1 setting under System Settings, the command
would begin with SPT 2 6
where 6 is the value Options_1. Note the space between each parameter.
UPMDR? Displays metering data
VER? Displays firmware versions
NOTE
Spaces are placed between each parameter, but not between characters or numbers in a
parameter. Using an underline here to represent a space, an example of a the syntax is:
SPT_2_6_0081. 0081 is the value parameter.
