Channel Setting
Press Channel to open the channel setting menu of the selected protocol. Different
parameters are to be set for different protocols. The module provides 16 data
channels and 2 clock channels. Users can select the desired data channel and clock
channel and set the channel voltage.
1. Channel Setting under RS232 Protocol
When “RS232” protocol is currently selected, press Channel to open the
corresponding setting menu.
 Press TX to select any channel (D0~D15) as the data line of RS232 output.
 Press AnalogCh to select On or Off. When “On” is selected, the analog
channel voltage (2.0V to 4.5V) of the digital module can be set and when
“Off” is selected, the analog voltage output is turned off.
Note: RS232 voltage is negative logic and has negative voltage. While the digital
channel cannot output negative voltage, it is always turned off.
2. Channel Setting under SPI Protocol
When “SPI” is currently selected, press Channel to open the corresponding
setting menu.
 Press SCLK to select any channel (D0~D15) as the clock line of SPI output.
 Press SDA to select any channel (D0~D15) as the data line of SPI output.
 Press CS to select any channel (D0~D15) as the CS line of SPI output.
Note: When setting SCLK, SDA and CS, the items selected in D0～D15 cannot be
selected again.
 Press DigitCh to select the digital channel voltage of the digital module: 1.8V,
2.5V, 3.3V, 4.0V, User or Off. When “User” is selected, the range available is
from 1.4V to 4.2V.
 Press AnalogCh to select On or Off. When On is selected, the analog
channel voltage (1.4V to 4.9V) of the digital module can be set and when
“Off” is selected, the analog voltage output is turned off.
Note: When analog channel voltage is adjusted higher than 4.2V, digital channel
voltage is automatically adjusted to be 3/8 of analog channel voltage. While,
