Creating A Configuration File
You may use
File-New
to create a new
configuration file, or
File-Open
to open
an existing configuration file. You may
also use
Module-Upload
Configuration
to retrieve the current
active configuration from the module
connected (recommended).
Uploading first is recommended as it will
automatically detect the correct model
connected and load the property sheets
for that model.
Once you create, open, or upload a
configuration file, a screen similar to the
one shown at right will be displayed.
The model number is indicated at the
top of the screen along with the current
file name. Model 903MB Configuration
is shown here. Your screen will vary
according to your model number.
Note that only 2 property sheets define
this transmitter’s configuration: General
and Test.

The Serial and Firmware numbers are
indicated at the top of the General screen
and cannot be modified.
For “Tag:”, enter up to 15 alphanumeric
characters (optional).
For “Comment:”, enter up to 31
alphanumeric characters (optional).
For “Configured By:”, enter your name up
to 15 alphanumeric characters (optional).
You can also add a “Location:” note of up
to 25 alphanumeric characters (optional).
For “ID Port:”, enter up to 15 alphanumeric
characters of identification information
relative to the port (optional).
Use the
“Slave Address”
scroll bar to
select a new module address that will take
effect following download. Select from 1 to
247. Address 247 is reserved for Default
Mode.
Use the
“Baud Rate”
scroll bar to select a
new baud rate to be used by the module
following download. Select 2400, 4800,
9600 (Default Mode), 14400, 19200,
28800, 38400, 57600, 76800, or 115200
bits per second.
Use the
“Parity”
scroll bar to select Odd,
Even, or No Parity (Default Mode) error
checking by the module.
Use the
“Response Delay”
field to specify
a delay from 0 to 65500 ticks with 1 tick
equal to 1.085 micro-seconds. Response
delay is the additional turnaround delay
applied between message receipt by the
module and its response to the host. A
fixed amount of delay is already present
and varies with the model. Thus, you will
have to specify a comparable amount of
response delay to measure any affect.
Some host software or signal converters
require additional delay to work properly.
Note that slave address, baud rate, parity,
and response delay selections take effect
following the next module reset and do not
alter the settings used by the host software
(which are configured separately via the
Settings
menu).
If you checked the “Update
Communications settings at download” box
of the Settings pull-down menu, the host
software will automatically change its own
settings to match the module settings that
take effect following download in an effort
to easily maintain communication with the
module. Otherwise, you must change the
host settings separately after downloading
to match the new module settings.
If the module is in Default Mode (indicated
via a flashing status LED), the baud rate,
address, and parity of the module are fixed
at 9600bps, 247, and No Parity.
The Test Screen of the next page also
provides configuration information with
respect to the port watchdog timers and
output timeout states.
