I/O Module Installation
The I/O module (N2861A) provides an RS-232 serial port and a GPIB port that
can be used to remotely program the 3000 Series oscilloscopes. Figure 2 shows
the back panel installation location for the I/O module.

I/O Module Installation
Figure 3 shows how to install the I/O module.
Figure 3
Installing the I/O Module
After installation is complete, restart the oscilloscope. The system will
automatically detect the I/O module. For example, a message at boot up stating
“Communication module installed” means the IO module has been installed,
while a message stating “No module installed” means there is no I/O module. In
this case, please check that the module is seated correctly.
Be sure to turn off the power before installing the I/O module.

I/O Module Configuration
After installing the I/O module, the port that you are going to use for remotely
programming the oscilloscope must be configured. To configure the I/O module,
press the front panel UTILITY key. In the UTILITY menu select the IO Setting
menu key.
RS-232 Configuration
The baud rate can be set to one of the following values:
•300
•2400
•4800
•9600
• 19200
• 38400
Table 1 RS-232 Data Format
Testing the RS-232 Interface
1Connect the oscilloscope to a computer using the appropriate RS-232
cable.
2On the PC, run a terminal-emulator program. Make sure the PC serial
port is set as follows:
