15 4 PROGRAMMING GUIDE Setting up for RS-232 or GPIB communication The SLS20 series source may be remotely controlled via GPIB (IEEE 488) and RS 232 interface. Many of the commands used for controlling the source are the same for both the RS 232 and the GPIB interface. Refer to the individual command descriptions to determine if the command applies to both GPIB and RS 232. Accessing the User Menu mode In order to establish communication between the computer and the source, the RS 232 bus or the GPIB bus must be configured properly. The different options for the communication are contained in the User Menu. Refer to the section User Menu Operation on page 13 for further details. Programming over GPIB The SLS20 supports the IEEE 488.1(1978) interface standard. It also supports the mandated common commands of IEEE 488.2(1987) standard. Before attempting to communicate with the SLS20 over the GPIB interface, the device address must be set. The address is set by accessing the user MENU function from the front panel. Programming Over RS 232 In order to establish a serial communication between the computer and the SLS20, the computer s COM port must be configured as described in Table 8. Table 8: Serial Communication Settings Baud Rate Data bit 8 Parity Selectable in the User Menu. Available options are 300, 1200, 2400, 9600, and bps N Stop bits 1 Flow Control None G UM Rev of 33

16 To connect the SLS20 to the computer, a standard 9 pin straight RS 232 cable is required. Only three pins, Txd, Rxd and GND are needed. Command Syntax ASCII characters are used in the commands to communicate with the SLS20. Commands may be in either upper or lower case and may contain any number of embedded space characters. A command consists of mnemonic, argument if necessary, and a command terminator. The command terminator should be a linefeed <LF> plus EOI for GPIB and a carriage return <CR> plus linefeed <LF> for RS232. No command processing occurs until a command terminator is received. Command mnemonics beginning with an asterisk * are IEEE 488.2(1987) defined common commands. Command may require one or more parameters. Multiple parameters are separated by commas, or space. Multiple commands may be sent on one command line by separating them by semicolons ;. The difference between sending several commands on the same line and sending several independent commands is that when a command line is parsed and executed the entire line is executed before any other device action proceeds. The SLS20 has a 128 character input buffer and processes commands in the order received. Command lines longer than 128 characters will be truncated, and may not be processed properly. The SLS20 has a 128 character output buffer to store the output characters until the host computer is ready to receive them. The GPIB output buffer may be cleared using the Device Clear universal command. G UM Rev of 33
