RS-232 Interface Configuration
You connect the power supply to the RS-232 interface using the 9-pin (DB-9)
serial connector on the rear panel. The power supply is configured as a DTE (Data
Terminal Equipment) device. For all communications over the RS-232 interface,
the power supply uses two handshake lines: DTR (Data Terminal Ready, on pin 4)
and DSR (Data Set Ready, on pin 6).
The following sections contain information to help you use the power supply over
the RS-232 interface. The programming commands for RS-232 are explained on
page 131 .
RS-232 configuration overview
Configure the RS-232 interface using the parameters shown below. Use the
front-panel
key to select the baud rate, parity, and number of data bits (see
page 80 for more information to configure from the front panel).
RS-232 Data Frame Format
A character frame consists of all the transmitted bits that make up a single
character. The frame is defined as the characters from the start bit to the last stop
bit , inclusively. Within the frame, you can select the baud rate, number of data
bits, and parity type. The power supply uses the following frame formats for seven
and eight data bits.
– Baud Rate: 300, 600, 1200, 2400, 4800, or 9600 baud ( factory setting )
– Parity and Data Bits: None / 8 data bits (factory setting)
Even / 7 data bits, or
Odd / 7 data bits
– Number of Start Bits: 1 bit (fixed)
– Number of Stop Bits: 2 bits (fixed)
