- Use
"Hyper Terminal
®", a simple utility for communicating via the serial
port, which is available on all PCs running
Windows 95
®
or 98
® or XP
® :
"Start\Programs\Accessories\Communications HyperTerminal".
- Set up the port as follows
(Fig. 11)
:
Bits per Second:
9600
,
Data bits:
8
,
Parity:
None
,
Stop bits:
1
,
Flow control:
None
- Select
File/Properties/Settings (Fig. 12)
Check
The backspace key returns:
Del, then click
ASCII Setup (Fig. 13)
:
In the
ASCII Sending area
, leave the check boxes unchecked, set
5
in
Line Delay
and in
Character Delay
.
In the
ASCII Receiving area
, check the 3 boxes, then click
OK.
- Save your setup.
You can now communicate remotely with your GF 266 generator
(Fig. 14)
.
6-3-2 COMMUNICATION PROTOCOL
The various functions are called by entering a 2-digit number
(see table at the end of the manual)
.
The tens digit replaces a button press and determines the selected menu.
The units digit replaces a thumbwheel switch action for selecting a parameter.
To validate and send digital data or parameters, press
"Enter"
(Return).
Example: To select the triangle function, type:
"0" "2" "Enter"
.
Explanation: As indicated in the table,
"0"
selects the
Function
and
"2"
select the
Triangle
parameter.
To know the value of a parameter, use the
"?"
key.
Example: If you type
"8" "0" "?
"
, you will be returned the current value of "Level", for example:
2.5 Vcc.
Note: For parameter interrogation, the unit is not significant.
Example: If you type
"8" "2" "?
"
, you will also be returned to "Level"
;
for example:
2.5 Vcc
To enter the numeric data of the parameter to be modified, use the
"space"
key.
Example: To change the level to 3.8 V, type:
"8" "0" "space
"
"3" "." "8" "Enter
"
Note: You can use either a decimal point or a decimal comma.
To navigate through the
Frequency counter, modulation, Store
and
Recall
menus, use
"Enter"
,
"O"
and
"K"
(OK) in
combination.
Example:To store the current setup in memory location 3:
"7" "3" "Enter
"
"O
"
"K"
Explanation: 7 represents the
Store
menu,
3
represents the third memory location, pressing
Enter
accesses this
memory location, as confirmed by the generator display, which displays
Store 3
on the lower line.
Press
"O"
and
"K"
to validate.
Other example: Measuring a frequency between 0.8 Hz and 25 MHz:
"1" "0" "Enter
"
"O
"
"K"
Explanation:
"1"
selects the frequency counter,
"0"
selects the 0 -25 MHz range.
Pressing
"Enter"
changes the lower line of the display as follows: F_ext 0-25 MHz.
Pressing
"O"
and
"K"
validates the selection: Frequency counter, 0 -25 MHz range, and starts the
measurement.
The measured frequency is then displayed
(Fig. 15)
.
To quit the frequency counter, simply enter another parameter, for example :
"0" "0" "Enter
"
(return to sine function).
