ECI0016PA Data Capture Card User Manual V1.5
range of the AIN command is 0~65535. For example, the voltage input range of the data
acquisition card is bipolar ± 10V, the scale value 0 corresponds to -10V, the scale value
32767 corresponds to 0V, and the scale value 65535 corresponds to 10V.
The analog output resolution of the data acquisition card is 12 bits, and the scale
value range of the AOUT command is 0~4095. For example, the voltage output range of
the data acquisition card is bipolar ± 10V, the scale value 0 corresponds to -10V, the scale
value 2047 corresponds to 0V, and the scale value 4095 corresponds to 10V.
Note: when watching the analogs, it is necessary to modify the scale value and the
value of the voltage or current range in the "ZDevelop/View/AD/DA" interface
.
Please refer to "ZBASIC Programming Manual" for details of the instructions.

CAN Bus Expansion
ZIO series expansion modules or ZMIO310-CAN coupler with sub modules can be
used.
Connect control card to CAN bus expansion modules, when the eighth bit of the DIP
switch of the expansion module is turned to ON, which indicates that a 120 ohm resistor
has been connected, but needs to connect one 120 ohm resistor externally. When
connecting multiple CAN expansion modules, you only need to dial ON for the eighth digit
of the last expansion module, which means please do not dial bit-8 of other modules.
4.2.1.
CAN Expansion Wiring
The ZIO expansion module is powered by the dual power supply. Except the main
power supply, an additional IO power supply is required to supply independent power for
IO. Both the main power supply and the IO power supply use 24V DC power supply. For
ZAIO, it only needs to connect to the main power supply.
To prevent interference, separate the IO power supply from the main power supply.
Please select the expansion module according to the requirements, and select IO
mapping or axis mapping according to the resources of the expansion module.
Wiring reference of connection between ZIO expansion module and control card and
standard wiring of CAN bus are shown as below (take ECI0016PA and ZIO1616 as the
