Serial Interfaces
There is one ST-compatible RS232 port, with DB9
connectors.
If you do not use an Agilent 5180-2477 RS232 cable or the
RS232 cable supplied with the rack, the EMI performance
of the optical time domain reflectometer cannot be
guaranteed.
Programming user tasks on a PC
You can select Input/output commands for sending and
receiving data from the serial interface and for initializing
transmission parameters.
You should follow the following steps:
1 Initialize the Hardware Interface parameters
2 Check the automatic connection to the instrument
3 Send or receive commands to/from the Mini-OTDR.
The OTDR Programming Guide (Agilent Product Number
E4310-91016) shows how to perform steps 2 and 3. Step 1
depends strongly on the Operating system.
NOTE The programming and speed performance depend on the
Operating system used on the PC. Generally speaking,
speed and reliability are better with Windows NT and
Windows 95 than with Windows 3.1.
