Are the above drive letters and path OK? (y/n) n
--------------------------------------------------------------------------
To specify different floppy drive, hard drive, or path, do:
floppy:install1 floppy harddisk directory
_
for instance, doing just "install1" from drive A is equivalent to specifying:
a:install1 A C MCU
_
_where the "a:" specifies the drive where the floppy disk is,
the "A" specifies the same drive (don't include a colon),
the "C" specifies the drive letter where the Office Software will be installed
(no colon), and the "MCU" specifies the directory where the Office Software
will be placed.
(the directory will be created if it doesn't exist, but any parent
directories must already exist; don't specify a leading backslash).
You can type upper or lower case letters, it doesn't matter.
You can leave out the harddisk and directory if C:\MCU destination is OK.

Returning to DOS now, please wait a moment.

TERMINAL HARDWARE CONNECTIONS
This subsection describes the four installation procedures available for Model 640 communica-
tions. Follow the steps for the connection type selected above.
Note: Even though several console interfaces are available, only one ZLINK connection can
be active at any given time.
Local Serial Connection
Use an RS-232 serial connection if the computer is located close to the Model 640 (distances
under 60 feet). A direct connection between the serial port of the Model 640 Paging Terminal and
a serial port on the office computer can communicate at rates up to 9600 baud. The communica-
tion rates are lower with longer cables.
Serial cables longer than 60 feet are not recommended, since induced EMI and other problems
may arise, causing communications interference. Worse yet, a long serial cable in the wrong RF
environment could possibly inject RFI into the Model 640 system, creating background noise or
operational interference.
The advantages of the serial interface are:
•
no additional phone lines are required to link up to the terminal
•
the communications rate is usually faster and more reliable
•
one of the paging terminal trunks does not have to be tied up for ZLINK programming and
database modification
