4.6.3.3 UPC STATUS (cont’d)
For systems equipped with a manual controller (UPC-3M or UPC-1M), the display will be:
UPC STATUS: FIRMWARE 141999 v4.25
TRANSFORMER RATIO 2.00 PAs=3
AMPS:VOLTS RATIO 4.00A=1 V PRI
To change any of these settings, press ENTER to move the cursor to each data field. Press EDIT when
the cursor is positioned on the value to be changed. Type the new value, then press ENTER to continue
editing or STORE to save and exit.
BAUD: 300, 1200, 2400, 4800, 9600, 19200, 38400. This is the serial port
baud rate. The factory default value is 19200.
PARITY: NONE, ODD or EVEN. The default serial port parity value is NONE.
LAST BYTE= This field indicates the last data byte (DAB) received by the remote
interface. The byte is shown in hexadecimal format. Hex 0D (Carriage
Return) is displayed as Hex 0A (New Line). This is used for
troubleshooting the remote interface.
GPIB ADDRESS: 0 to 30. This is the IEEE-488 device address for the UPC. The factory
default address is 1.
IFC: “Interface Clear”. This is displayed only if an IEEE-488 Interface
Clear message is received while this status display is shown. This
display latches the IFC message. Press CLEAR to clear this display
and the IFC field. It is used for troubleshooting the GPIB interface.
LAST DATA BYTE= Same as LAST DATA BYTE, above.
TRANSFORMER RATIO: Output Transformer Ratio: To change this see section 3.4.1
CONFIGURE TRANSFORMER RATIO. The value MUST match the
ratio of the output transformer presently installed.
PAs= 1, 2, or 3. This is the number of power amplifiers in the Power
Source. To change this value, refer to para. 3.4.4 CONFIGURE
MISCELLANEOUS SETTINGS.
AMPS:VOLTS RATIO This sets the ratio of current to voltage for the UPC metering signals.
To change this see para 3.4.2 CONFIGURE AMPS TO VOLTS
RATIO.
PRI/SEC: PRImary or SECondary. This is the current transformer location
relative to an output transformer. To change this value, refer to para
3.4.4 CONFIGURE MISCELLANEOUS SETTINGS.
EOS: CR/LF, LF or CR. The factory default Serial port End-Of-String
character(s) value is CR/LF. Use the +/- key to select this value.
