MCU (Model 640 Communications Utility)
MCU is a user-friendly interface to all aspects of the Model 640 programming. It can be accessed
only from a personal computer connected to the Model 640 by way of modem or local serial
cable. MCU provides easy-to-follow pull-down menus, on-screen help, and a useful tutorial that
overviews the hardware and software of the paging terminal.
MCU allows the system operator to monitor system traffic (log files) and view statistics and call
counts. MCU also provides system management with ZLINK interface to the paging terminal.
ZLINK (Plus Prompt “+” Commands)
“Plus Prompt” commands are available either through MCU, ZLINK connection or by way of an
alternate communications program, such as ProComm® or Kermit™. ZLINK programming is
intended for use by advanced programming personnel only. ZLINK is much like DOS in format
and provides over 60 commands for monitoring and managing the paging terminal’s operation.
These commands are generally diagnostic in nature, but also include commands to access the
database and common service-related items. In addition, ZLINK provides commands to generate
test pages and view trunk card configuration and activity.
Model 640 Subscriber Database
The Model 640 database can be accessed by way of MCU or another communications program.
Any dumb terminal or personal computer can link directly into the Model 640 database, stored
on the RAM disk. The database configures system parameters such as subscribers, telephone line
operation, transmitter operation, and general system operation.
Computer Requirements
The following minimum computer configuration is required to operate MCU:
IBM-compatible PC
640 KB of RAM
1 MB of available hard disk space
3½-in floppy disk drive
Microsoft DOS Version 3 and above, or Windows 95, 98
Modem (internal or external) if the office computer and Model 640 are not located within
60 feet of one another
MCU INSTALLATION
The MCU communications program should be installed on the office computer’s hard drive.
Note: MCU cannot be used with a dumb terminal or console kit communications setup. If
the system application is not using a computer, skip this section.
To install MCU on the office computer, follow the steps below:
