COMMUNICATIONS SETUP
OVERVIEW OF MODEL 640 COMMUNICATION
Communicating with the Model 640 can be achieved several ways. Zetron has designed the
paging terminal to allow for programming flexibility and convenience.
A communications link with the Model 640 should be established before the system is interfaced
to the radio station and telco. This order of installation aids the technician in “seeing” what is
going on with the paging terminal. Diagnostics and testing are simplified when the communica-
tion link is already available. In addition, the three software modules included with the Model
640 can help any technician understand how the system is designed and meant to be operated.
Setting up the communications link is established in four major steps:
1) Determine the type of communication link best for the custom system application.
2) Install MCU on the office PC (if applicable).
3) Make the appropriate hardware connections between the terminal and the Model 640.
4) Establish the ZLINK communication with the paging terminal.
Each of the four installation procedures in this section lists and describes the specific steps to
access the paging terminal. Carefully follow each checklist, in order. Some of the subsections
may not be required. Simply skip the procedures that do not apply to the specific application.
Note: This section only includes the basics on using MCU for ZLINK communications.
Refer to the Model 640 Operating and Programming Manual (Part No. 025-9417) for
details on the software operation of the paging terminal.
Interface Flexibility
The Model 640 is very flexible regarding programming access. The system programmer can gain
access by way of several hardware configurations:
• Local serial-interfaced PC running dumb terminal emulator software (MCU or equivalent)
• Remotely located PC with a modem interface running dumb terminal emulator software
• Local serial-interfaced dumb terminal
Communications Software
Each of the hardware interfaces may require one or more of the three software tools shipped with
the Model 640. Each software module is designed for use with the others or as a stand-alone
interface. Refer to the Model 640 Operating and Programming Manual (Part No. 025-9417) for
more details on software programming and operation.
