120 – Operating and Maintenance Instructions
• A terminal program, such as Hyperterminal, which is supplied with Windows 95, or Terminal,
supplied with DOS.
In the following procedure, Hyperterminal is used. The procedure for setting the number of points
on the SOM is:
1. Connect the computer Comm Port 1 to the RS232 Control port on the SOM. The SOM has
several RS232 ports (each is clearly labeled). Ensure that the correct port is selected.
2. Run the Hyperterminal program.
3. Create a new connection.
4. In the Hyperterminal program, select the File and Properties menu items. Set the
communications protocol to the following values:
Bits per second 1200
Data bits 8
Stop bits 1
Parity None
Flow Control None
5. Select ASCII Setup from SETTINGS. Select the following options:
Send line ends with line feeds
Echo typed characters locally
Append line feeds to incoming line ends
Wrap text
6. Type *IDN? <CR> A line starting with “JDS Uniphase” is displayed. If the system does not
respond to keyboard inputs, check the REMOTE LED on the front panel of the SOM. The
LED should be lit. If it is not lit, communication between the computer and the SOM has not
been established. Check the connections and try again. If communication cannot be
established, or if communication is established but the SOM does not respond to keyboard
inputs, try the other COMM port on the computer. If communication cannot be established,
call the JDS Uniphase service hotline.
If communication between the SOM and the computer is established, perform the following
procedure to enter the parameter to be initialized in the SOM, where <CR> denotes carriage
return:
1. Enter the following line:
:FCOUNT?<CR> (Correct response from the SOM is a value of 17500 for a C-band
SOM
2. Enter the following lines:
:FCOUNT 18500<CR> (C-band) or :FCOUNT 29700<CR> (L-band)
:SAV<CR>
:FCOUNT?<CR>
