Calibration Application
The calibration application is used to read radio calibration files, perform
diagnostic functions, change certain settings, perform calibration tests,
view and check calculated calibration data, and program radios with
calibration files. To run the application and become familiar with its
features, proceed as follows:
1.
Click
“Start”
>
“Programs”
>
“Tait Programming Applications”
>
“TM8200 Calibration Application”
. The calibration application is
opened.
2.
On the menu bar, click
“Help”
>
“Contents and Index”
. The on-line
help facility is opened.
3.
Read the information provided by the on-line help facility.
4.
Close the on-line help facility and close the calibration
application.
Computer-controlled
Test Mode
The servicing procedures require a radio to be placed in the computer-
controlled test mode. In this mode CCTM commands can be entered at
the test PC. These commands are then relayed via the test unit to the
radio. Certain CCTM commands cause the radio to carry out particular
functions; others read particular settings and parameter values in the
radio. The CCTM commands of use in servicing radios are listed in
Table 1.1 to Table 1.5, grouped according to category.
Terminal Program
for CCTM
To place a radio in CCTM requires the use of a terminal program on the
test PC. An example is HyperTerminal, which is supplied with
Microsoft Windows. As a preliminary, first select the settings for the
communications port as follows:
1.
Open the terminal program. (In the case of HyperTerminal, click
“Start”
>
“Programs”
>
“Accessories”
>
“Communications”
>
“HyperTerminal”
.)
2.
In the terminal program first select the COM port to which the
radio is connected. Then select the following settings for the port:
■
bits per second : 19 200
■
data bits
: 8
■
parity
: none
■
stop bits
: 1
■
flow control
: none
3.
Click the
“OK”
button (or equivalent).
4.
Save the file with the port settings under a suitable name. For
subsequent sessions requiring the terminal program, open this file.
