NOTE: All characters in the ASCII command string must be in UPPER CASE ONLY. The
interface will not recognize lower case characters.
The syntax of the commands is fairly rigid, especially the format of the numeric voltage and current strings.
Table 3.0 shows the numeric formats for programming the Model 200-C488 high voltage power supply.

3.2.1
PROGRAMMING THE HIGH VOLTAGE OUTPUT (‘P’)
This command allows the user to set the output voltage of the power supply. The syntax is:
‘P {numeric string} K’
Where {numeric string} is an ASCII string of five digits with a decimal point. The resolution of the
programming value (and monitors) is five digits. Since a Series 205A/210 power supply may each have a
different output rating, the programming command will have different formats. In general, the program
command will be one of those shown below:
Px.xxxxK
Pxx.xxxK
The numeric format (x.xxxx or xx.xxx) will depend on the unit being controlled. This numeric format must
be packed with zeros to fully fill five digits and decimal point. Therefore, if a 1kV power supply, with
format x.xxxx is to be programmed to 230 volts, the command will be P0.2300K. If a 20kV supply is to be
programmed to 11,500 volts, the command will be P11.500K.
The actual high voltage output will not change after the program command until the 200-C488 receives a
device trigger bus command or the ‘G’ command string (see sections 3.1.4 and 3.2.3).
3.2.2
SETTING THE OUTPUT LIMITS (‘L’)
The 200-C488 monitors the power supply output voltage and current to detect if the parameters exceed the
user thresholds. Each parameter (voltage and current) is monitored at the rate of once per second. The user
may set threshold limits that when exceeded will invoke the user programmed shutdown and service
