USER’S MANUAL

Programming Guide

RS232 Serial Interface

The RM meter is equipped with an RS232 serial interface. Through the RS232 connection, the user can download measured values of backreflection, loss, and power to a computer or printer. The RM meter can also use an IEEE 488 parallel interface through the external RS232- to-IEEE 488 converter (described in the RS232-GPIB Converter section).

The RS232 serial interface is configured as data terminal equipment (DTE). The data protocol is set to 2400 baud, ASCII character code with eight bits per character, two stop bits, and no parity bit.
