Instruction manual

Programming in Volts or Amps.
Programming as a percentage of full scale.
Programming the DAC directly in hexadecimal.
The control channel programming commands are of the following forms:
Direct programming (Volts or Amps):
“Program Control +10.000” = “PC+10.000” = “PC10” =
Program to +10.000 Volts or Amps
“Program Control -5.432” = “PC-5.432” =
Program to -5.432 Volts or Amps.
“Program Control 0.000” = “PCO” = program to Zero.
Percentage full scale programming (-%99.99 to +%99.99):
“Program Control %50.00” = “PC%50”
“Program Control %99.99” = “PC%99.99” =
Program Control to %99.99 full scale (max scale)
Program Control -%0.25” = “PC-%.25” =
Program Control to negative %0.25 full scale
Hexadecimal programming (0000h to ffffh):
Program Control heX 0000” = “PCX0” =
Program Control DAC to 0000h (-full scale)
Program Control heX 7fff” = “PCX7fff” =
program Control DAC to 7fffh (zero)
“Program Control ffff” = “PCXffff” =
Program Control DAC to ffffh (+full scale)
“Program Control heX 4000” = “PCX4” =
Program Control DAC to 4000h (+half scale)
6.7 LIMIT CHANNELS PROGRAMMING
The positive and negative limit channels are determined by the control channel
selection. If the control channel is the Voltage channel, then the limit channels limit the
Current channel of the BOS/S. If the Current channel is the control channel, the
Voltage channel is limited.
the positive and negative limit channels are independently programmed signals, each
with a resolution of 8-bits. There are two methods of programming the limits, these
are:
Programming as a percentage of full scale.
Programming the DAC directly in hexadecimal.
Percentage full scale programming (00 to %99, 0 to -%99):
“Program Limit +00” = “PL+00” = Program +Limit to zero
