GEN Protocol (GEN series communication language)
GEN communication language is supported to provide compatibility to the legacy GENESYS
Programmable Power Supplies Series. To use the advanced functions of the Power Supply, refer
to SCPI language, section 5.12.
Recommended time delay between commands: 5mSec minimum.
NOTES:
• The address (ADR n) command must return an ”OK” response before any other
command is accepted.
• GEN language is supported only in Serial communication interfaces (RS232, RS485 and
USB).
5.9.1 Data Format
Serial data format is 8 bit, one start bit and one stop bit.
No parity bit.
5.9.2 End of Message
The End of Message is the Carriage Return character (ASCII 13, 0x0D).
Power Supply ignores the Line Feed (ASCII 10, 0x0A) character.
5.9.3 Command Repeat
The backslash character ”\” causes the last command to be repeated.
5.9.4 Checksum
The user may optionally add a checksum to the end of the command. The checksum is ”$” followed
by two hex characters. If a command or a query has the checksum, the response will also have
one. There is no CR between the command string and the ”$” sign. Example: STT?$3A
STAT?$7B
5.9.5 Acknowledge
The Power Supply acknowledges the commands received by returning an ”OK” message. If an
error is detected, the Power Supply returns an error message. The rules for the checksum apply to
the Acknowledge feature as well.
5.9.6 Backspace
The backspace character (ASCII 8) clears the last character sent to the Power Supply.
