NFS-640 Installation Manual P/N 51332:B2 07/27/2004 51
3.9.4 Installing and Configuring a CRT-2
A CRT-2 can only be used in a non-networked application when used with the NFS-640. For
further details on setting up the CRT-2, refer to the NFS-640 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 TB15 terminal block on the control
panel as shown in the figure below.
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 below.
Figure 32 Connecting a CRT-2
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 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>.
Table 8 shows the standard settings for using the CRT-2 with the NFS-640; for one instance where
these settings may change slightly see Section 3.9.6 “Connecting Multiple Printers, CRTs, or
CRT/PRN Combination”. The basic settings for using the CRT-2 with NFS-640 are:
• Baud Rate 9600 • Data format 8 1 N • Protocol xon/off.
Note: This section covers installation only; for information on how the CRT-2 functions as part of
the fire alarm system, see the NFS-640 Operations Manual.
