RMS Enterprise - Installation Checklist
NI Central Controllers and Enova All-In-One Presentation Switchers that come equipped with 64MB of RAM
(and therefore could potentially experience this error) are listed in the following table:
To avoid this error, it may be necessary to increase the Duet memory allocation on the NI Controller or
DVX-2100HD switcher. The Duet memory allocation setting can be viewed and adjusted via the telnet
terminal commands described below:
There are some considerations when doing this:
The higher you increase the Duet memory, up to a maximum of 64Mb, the less memory there is for
the NetLinx code to run. To find out how much Duet memory you need to run your program is by
trial and error.
We recommend increasing it by 2Mb, then trying to run your program. Repeat this process until
your code runs as expected.
It is important to keep the amount of memory allocated to Duet as low as possible so there is
maximum memory to run the NetLinx code.
Setting the Duet Memory Allocation Value
1. Telnet into the Controller (refer to the relevant Operation/Reference Guide for details).
2. Type SET DUET MEMORY. You will be presented with how much the memory is currently set to and a
prompt for the new setting.
3. Enter the new setting (such as 14 to set the Duet memory allocation to 14MB), then press ENTER.

Enova DVX-2150HD/2155HD and DVX-3150HD/3155HD All-In-One Presentation
Switchers come equipped with 256MB of RAM. NI Controllers and Enova DVX
Switchers with 256MB of RAM should not experience this issue, since their default
Duet memory allocation setting is 36 MB.
DUET MEMORY Telnet Commands
GET DUET MEMORY Display the amount of memory allocated for Duet Java pool.
This is the current Java memory heap size as measured in Megabytes.
An example is a value of 12 = 12MB.
SET DUET MEMORY Set the amount of memory allocated for Duet Java pool. This is the current Java
memory heap size as measured in Megabytes. This feature is used so that if a NetLinx
program requires a certain size of memory be allotted for its currently used Duet
Modules, it can be reserved on the Central Controller.
The default Duet memory allocation value for NI Central Controllers with 64MB of
SDRAM (as well as the DVX-2100HD) is 12MB
Note: This setting does not take effect until the next reboot.
Terminal commands can be sent directly to the NI Controller or DVX-2100HD via
either a Program Port or a Telnet terminal session. In your terminal program, type
"Help" or a question mark ("?") and <Enter> to access the Help Menu, and display the
supported Program port commands.
Refer to the "NetLinx Integrated Controllers WebConsole and Programming Guide"
for a full listing of supported telnet terminal commands.
