3.13.4 Installing and Configuring a CRT-2
A CRT-2 can only be used in a non-networked application when used with the NFS2-640/E. For
further details on setting up the CRT-2, refer to the NFS2-640/E Operations Manual.
Connect a CRT-2 to the Control Panel as follows:
1. Connect the three (3) open leads of the custom cable to the TB12 terminal block on the control
panel as shown in Figure 3.27.
2. Plug the DB-25 connector end of the custom cable into the EIA-232 port of the CRT-2. Tighten
securely.
3. Set parameters as discussed in Table 3.27.
Setting CRT-2 Parameters
The CRT-2 communicates with the control panel through a protocol defined by thirteen groups of
parameters. To access a parameter group, press the corresponding function key (F1-F12) as shown
in Table 3.8 below. You can then program parameters in each group.
Enter the CRT-2 setup menu by pressing and holding the <Ctrl> key while pressing the <Scroll
Lock> key. Use arrow keys to move through the selections in each setup group; press the space bar
to view the options for each parameter. When finished programming all setup groups, press the
<Pause> key. To save all changes, press <Y>.
