  • Page 25 3.4 Configuring the RS-232 Settings of This Instrument Explanation Handshaking To use the RS-232 interface to communicate with a PC, the devices on both sides must negotiate a set of rules to ensure the proper transfer of data. This negotiation is called handshaking. Because there are many handshaking methods that can be used between this instrument and the PC, you must make sure that the same method is chosen by both this instrument and the PC. You can choose any of handshaking methods shown below.
  • Page 26 3.4 Configuring the RS-232 Settings of This Instrument CS-RS Data Transmission Control Hardware handshaking is performed between this instrument and the PC. If CS is set to false while this instrument is sending data, it stops the data transmission. Then, if CS is set to true, it resumes the operation. The “X-OFF” and “X-ON” signals are treated as data. Data Reception Control Hardware handshaking is performed between this instrument and the PC. When the free area of the receive buffer falls to 64 bytes, this instrument sets RS to false. When the free area reaches 192 bytes, this instrument sets RS to true. Notes on Data Reception Control When handshaking is used to control the reception of data, data may still be received from the PC even when the free space in the receive buffer drops below 64 bytes. In such cases, if the receive buffer becomes full, excessive data will be discarded, regardless of the handshaking method.
  • Page 27 3.4 Configuring the RS-232 Settings of This Instrument Data Format The RS-232 interface of this instrument performs communication using start-stop synchronization. In start-stop synchronization, characters are transmitted one at a time. Each character consists of a start bit, data bits, a parity bit, and a stop bit (see the following figure).
