Option Switches

The Developer Board contains 7 option switches that are described in the following paragraphs.

Analog to Digital Converter (ADC) - S160, S161

Note:
Note:
The Developer Board can route up to 8 different analog voltage levels to the 3 G30 analog to
digital converters, using the S160 and S161 switches.

Figure 2-18: S160, S161 Switches
Voltage level is set using the S161 switches and routing of the voltage to the desired A/D is done
using the S160 switched.
When simulating a desired voltage level to either of the A/D lines, perform the following steps:
1. Turn the desired voltage level switch (labeled LEVEL1-LEVEL8) to ON.
Note:
December 15, 2009
Applying voltage to ADC lines before power up is forbidden and may cause G30
power up issues.
G30 Adapter Board supports dual ADC. ADC1 and ADC2 are applicable.
G30 ADC voltage input range is 0V-1.92V. Therefore, only level 1 to level 7 are
applicable.
shows the ADC switches (S160, S161) provided on the Developer Board, which are
S160 switches must be placed Off (all switches to left side) before power up.
S161
In order to have the correct voltage level, verify that only a single level switch is turned
ON.
