3.2.4 Operational sequence
Using a terminal program configured for the communications settings previ-
ously mentioned, input the following commands in the defined sequence.
User Inputs are shown with quotations to designate the exact command the
user must input, the quotation marks should not be input into the terminal
program.
• During power up of the Discharge Power Supply set the output to zero
current output for safety. Input “VA0” then press the enter key.
• Determine the Discharge output current required. Using the following
formula, determine the decimal value required for input into the terminal
program corresponding to the required Discharge current :
Input value = required discharge current = (0 to maximum amps) x
4095/10.
Example: A value of 5 amps of discharge current is desired. Using the
above formula, 5 X 4095/10 = 2047 for model DC30010.
• Determine the Discharge output Voltage required. Using the following
formula, determine the decimal value required for input into the terminal
program corresponding to the required Discharge voltage :
Input value = required discharge voltage = (0 to maximum volts) x
4095/300.
Example: A value of 200 volts of discharge voltage is desired. . Using

the above formula, 200 X 4095/300 = 2730 for model with a maximum
voltage of 300 volts.
• Input “VAxxxx” then press the enter key. Note: xxxx corresponds to a
decimal number from 0-4095. For the example above, input “VA2047”
into the terminal program and then press the enter key to set the output to
half the maximum current in amps.
• Input “VBxxxx” then press the enter key. Note: xxxx corresponds to a
decimal number from 0-4095. For the example above, input “VB2730”
into the terminal program and then press the enter key to set the output to
two third (2/3) the maximum voltage in volts.
• Powering down the Discharge Power Supply should be done by resetting
the output current to zero, this is done by inputting the following command
into the terminal program: Input “VA0” then press the enter key. The out-
put will drop to zero and the Standby LED will be illuminated.
• Output Current: Monitoring of the output current can be done using the
following command: Input “RD0” then press the enter key. This reads
a decimal number from 0-4095 that can then be converted to the cor-
responding output current. To convert the decimal number to the output
current, divide the returned value by 4095 and multiply by the maximum
current.
Returned value/4095 X maximum current.
Example: The command RD0 was sent to the Discharge Power
Supply and the value 2048 was returned from the terminal program.
To convert this value to the output current take 2048 and divide by
4095, times 10 equals 5, this would give a output current of 5 amps for
model DC30010.
• Output Voltage: Monitoring of the output voltage can be done using the
following command: Input “RD1” then press the enter key. This reads
a decimal number from 0-4095 that can then be converted to the corre-
sponding cathode current. To convert the decimal number to the output
voltage divide the returned value by 4095 and multiply by the maximum
voltage of that model power supply.
Returned value/4095 X maximum output voltage.
Example: The command RD1 was sent to the Discharge Power

Supply and the value of 2048 was returned from the terminal program.
To convert this value to the output voltage, divide 2048 by 4095 and
multiply by 300 volts for model DC30010 power supply.
3.3 Remote Mode Analog
The Discharge Power Supply can be operated using analog.
3.3.1 ANALOG Input/Output
The Discharge Power Supply can be remotely controlled using a 0-5 volt DC
analog interface. The analog remote uses 0-5 volt signals for controlling and
monitoring the Power Supply. There is one 25 pin female D connector la-
beled ANALOG on the back of the Power Supply for connection to the analog
interface. The pin descriptions for the interface are given below in table 1.
There is a button on the front panel that can be used to switch from remote
to local control. There is also a two pin Molex connector on the back panel
labeled INTERLOCK. The pin descriptions for the interlock are also given
below in table 3-4.1.
