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 99.
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 59 for more information to configure from the front panel).
• 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 )
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.
