Note: in the 16-bit S02S01, S02 is the upper 8-bit bank. In the 16-bit S04S03,
S04 is the upper 8-bit bank. In the 32-bit S04S03S02S01, S04 is the upper 8-bit
bank.
5 Type
When the channel status is READ, use the up/down direction keys to select
Type and use the left/right direction keys to select the desired level (“TTL”,
“CMOS5V”, “CMOS3.3V”, “CMOS2.5V” or “User”). If “User” is currently selected,
use the up/down direction keys to select Level and Threshold respectively and
use the numeric keyboard to input the desired values.
 The range of level is from 2.000 V to 5.000 V and the default is 5.000 V.
 The range of threshold is from 0.500 V to 3.500 V and the default is 2.500 V.
 When setting the level and threshold, they should fulfill the relation
equation: Level ≥ Threshold + 0.5 V.
 When the input signal <Threshold–0.3 V, it is regarded as logic 0; when the
input signal >Threshold+0.3 V, it is regarded as logic 1.
6 Coding
Enter the fourth step of the channel configuration guide. By default, Coding is
selected and use the left/right direction keys to select “Binary”, “Decimal” or
“Hex”.
The coding mode selected will be used in both the digital input and output of
this channel.
Key Points:
1 When the DIO channels are used as digital input channels, they do not have to
be part of the scan list and the DMM module does not have to be enabled to
generate an alarm when the reading matches or dismatches the specific data
pattern.
2 DIO channels added into the scan list cannot be used as digital output channels.
