The checksum is “$” followed by two hex characters. If a command or a query has a checksum, the response will also have one.

    7.8. Global Output Commands 7.8.1. Description Global commands are a way to quickly set all power supplies on the RS-232/485 bus to the same setting. For example, sending “GOUT OFF” is one way to turn a whole group of supplies OFF at nearly the same time. NOTE After sending a global command, it is important that the controller wait 200 mSec before sending any more RS-232/485 messages.

    7.11. Status, Error, and SRQ Registers 7.11.1. General Description This Section describes the structure and operation of the six status, error, and SRQ registers. The registers can be set or read via the RS232/RS485 commands. Refer to Fig. 7-7 for the Status and Error Registers Diagram. NOTE These registers operate in a way that is similar to the IEEE-488 and SCPI registers (as used by the Genesys™...

    7.11.2. Conditional Registers The fault Condition Register and the Status Condition Register are read-only registers that the user may read to see the condition of the Power supply. Refer to Table 7-7 for description of the Fault Condition Register bits and Table 7-8 for the Status Condition register bits.

  • Page 89: Service Request: Enable And Event Registers

    7.11.3. Service Request: Enable and Event Registers The conditional Registers are continuously monitored. When a change is detected in a register bit which is enabled, the power supply will generate an SRQ message. The SRQ message is: “Inn” terminated by CR, where the nn is the power supply address.

    8. ISOLATED ANALOG PROGRAMMING OPTION 8.1. Introduction Isolated Analog Programming is an internal Option Card for analog programming of the Genesys™ power supply series. The option is factory installed and cannot be obtained with a GPIB (IEEE-488) Interface. Output Voltage and Output Current can be programmed and readback through optically isolated signals which are isolated from all other ground references in the power supply.
