3.9.5 Elgar Terminal Interface (ETI) Data Request Commands
The GUPS 2400A-107 RS-232 text data mode commands have been developed for use by a
program running on a host computer. The ETI mode data request commands provide formatted
responses of only the measured value data in a formatted form. Each of the ETI data request
commands supported by the GUPS 2400A-107 is described below.
3.9.5.1 Provide Calibration Values
Enter a command ‗l‘ (lowercase L) character to obtain the calibration constants for the A/D
converter algorithms values. For example, this command will return the GUPS 2400A-107
calibration constants in the following order:
Output Current at 80% // current calibration in hexadecimal
Output Current at 105%
Output Current at 150%
Minimum Output Voltage
// voltage calibration in hexadecimal
Maximum Output Voltage
Battery Good Voltage
// battery voltage in hexadecimal
Battery Bad Voltage
Battery Shutdown Voltage
Output Voltage Measurement
// scale factor in floating point
Output Voltage Measurement
3.9.5.2 Provide Status Words and Hexadecimal A/D Values
Enter a command ‗m‘ (lowercase M) character to obtain the Status Words and hexadecimal A/D
calibration constants for the A/D converter algorithms values. For example, this command will
return the A/D values and the unit status in the following order:
Status word 1 // 16-bit status flags in hexadecimal
Status word 2
Output Voltage
// A/D values in hexadecimal
Output Current
AC Input Voltage Line A-B
AC Input Voltage Line B-C
AC Input Voltage Line C-A
Battery/Charger Voltage
The status word formats are explained in Section 3.9.6.
3.9.5.3 Provide Status Words and Floating Point A/D Values
Enter a command ‗n‘ (lowercase N) character to obtain the Status Words and floating point A/D
calibration constants for the A/D converter algorithms values.
This command will return the A/D values and the unit status as in the ‗m‘ command, but the
voltages and currents will be returned in IEEE floating point format.
