N-1000-III-X is shown in Figure 2-3 with enclosure and battery. Figure 2-4 shows
the N-1000-IV-X with Four Reader Board, battery and enclosure.
The minimum configuration for the N-1000-III/IV includes the control panel,
power transformer, reader and communication converter.
Control panels can operate in a buffered mode in which system transactions are
stored in transaction buffer memory at the panels rather than transmitted to the
programming device. Every transaction (input point change of state, code use) uses
one location in buffer memory. The buffered information can later be transmitted
to the programming device.
The N-1000-III/IV firmware (version 08.01.29 or later) has a built-in test capability
that can be used to check the functioning of most of the circuit board’s hardware.
Refer to Appendix C: Troubling Shooting for details.
2-2: Programming Devices
N-1000-III/IV control panels in a communications loop are programmed with a
personal computer, printer/programmer or data terminal.
When using a personal computer as the system programming device, the PC
software serves as a database manager for the N-1000-III/IV control panels.
Information is entered into the PC databases and then downloaded to the
control panels. During the download procedure, the PC software converts the
database information at the disk level to a series of command strings from the
N-1000 instruction set. The commands are then sent to the appropriate control
panels. The panels then operate independently from the computer. The advan-
tages of using a computer as the system programming device include ease of
programming and operation, permanent disk storage of all database
information and extensive report options.

Typical 485-Multidrop Configuration.
The N-1000-III/IV can be used in
existing N-1000-II/N-800 systems provided the existing panels have version 8.0 or higher
firmware. When the N-1000-II/N-800 is configured for 485 (N-485-API-2) as in this example, the
firmware version must match the 485 version in the N-1000-III/IV.
