Communications
D-6 Using the MODASST Program
The Find Module option is available when you want to communicate with a
MODNIM or TIWAY Gateway module and the communications parameters
are not known. This selection tries the various parameter combinations
until either a successful match of communications parameters is found, or
all combinations have been tried. This option then displays on the screen
the communications parameters determined and an option to choose those
as the parameters to use for module setup.
The Talk to Module option tries to communicate with the MODNIM or the
TIWAY Gateway module using one of the following choices.
Check Module Communications sends a few read requests to the
module and displays on the screen if communications were successful.
Prompt for Info to Send prompts for the function to send and for
each of the function fields. (These are described in Chapter 2 of the
user manual.) The function is then packaged properly and sent to the
MODNIM or TIWAY Gateway module.
Expert, Send Specific Request allows you to type a complete
function request on the screen. Refer to Chapter 2 for request format.
(The start field, LRC or CRC field, and Ready field do not need to be
entered; they will be computed before being sent.) The program then
sends the request to the module. The response from the module is
displayed exactly as it is returned from the module. All fields are
displayed.
This option will Batch Send a file to the module. It prompts for the input file
name and for the output file name. If you do not change them, it assumes
modasst.tst as the input file name and modasst.log as the output file
name.
After using the MODASST program to verify that communications with the
MODNIM or Gateway are functional and properly configured, you may still
find that network communications are not operating in your installation. In
that case, the network cabling from the MODNIM or TIWAY Gateway
module to the host computer or the host computer itself may need to be
evaluated to determine the source of the problem.
