Setting the RS232 Serial Interface
To set the RS232 interface:
1. Press the MENU key.
2. Press the soft key labeled REMOTE MENU.
3. Press the soft key labeled EMULATION: RX3.
4. Press the soft key labeled INTERFACE: RS232. The GPIB address is displayed.
5. Press
the or key to set the interface to the required address.
6. Press the BR or POWER key to exit Menu mode.
The RS232 serial interface is configured as Data Terminal Equipment (DTE) and operates at
1200 baud. The communication protocol is set to ASCII character code with eight bits per
character, two stop bits, and no parity bits.
To connect the RX3 meter to the serial port of a DTE (computer), use a straight-through cable.
On power-up, the RTS and DTR signals on the interface connector become positive, indicating
that the RS232 interface is ready to communicate. The interface controller then waits for the
CTS line to become positive before the measurements are transmitted. For the RX3 meter to
receive commands, the DCD line must become positive.
To initiate each measurement and transmission, the command G must be sent to the RX3
meter. In addition, other commands can be sent via the RS232 interface to control the meter.
