Chapter 3: Option Selection
Voltage output ranges are determined by jumper placement as described in the following para-
graphs. Also, the method to update D/A outputs is programmable as described here and in the
Programming section of this manual.
Output Ranges
To select output voltage ranges (either unipolar or bipolar) set three jumpers located below each
DAC output chip. The jumpers select the polarity and range of each DAC channel.
Voltage Range Mode “M” and Initialize Jumper “I” Range Jumper “R”
0 to +5 V Unipolar 5V
-5 to +5 V Bipolar 5V
0 to +10 V Unipolar 10 V
-10 to +10 V Bipolar 10 V
Analog Outputs Update
Analog outputs are updated under program control in either one of two ways:
(a) Each channel is normally updated individually when new data are written to the related high-byte
base address. This “individual update” mode may be set by a special read operation as defined
in the programming chapter.
OR
(b) The outputs of all D/A’s may be updated simultaneously. This is done by first enabling
simultaneous updating for all outputs and then preloading the high and low bytes of each DAC
and then initiating a simultaneous update. (Simultaneous update mode is the default on power
up.)
Refer to the Programming section of this manual for more detail.
