Environment Variables

Table B.1 in this appendix contains a list of environment variables for the
CVIM2 system. The table includes the default, minimum, and maximum
values for each variable, along with a recommended value, in some cases.

Environment variables are case sensitive and must be entered exactly as
shown in the “Name” column of Table B.1 and in the “Usage” examples.
After adding an environment variable to the list in the

Environment

panel,

you must cycle power, since environment variables are read only during the
system initialization phase immediately following powerup. (Refer to the
Adding Variables section of Chapter 10, page 10–5, for more information.)

NOTE: When an environment variable is not present in the

Environment

panel list, a default value is assigned to that variable.

Indicates the type of monitor connected to the
CVIM2 system. For most applications, the
CVIM2 module will detect the type of monitor
that is connected and set the value for DMod
Values are:
1 – RS–170 (e.g. 2801–N8)
2 – CCIR (Do Not Set!)
3 – VGA (composite sync)
4 – VGA (separate H & V sync)
