2.1. Product Check List
In addition to this manual, the package includes the following items.
!A-626 / A-628 Analog output Card
!A-626 / A 628 utility diskette
Note : If any of these items is missing or damaged , contact the dealer who provides
you this product. Save the shipping materials and carton in case you want to ship or
store the product in the future.
The A-626 / A-628 Card contains sensitive electronic components that can be easily
damaged by static electricity.
The card should be protection on a grounded anti-static mat. and operator should be
wearing an a grounded anti-static wristband.
2.2. Jumper and DIP Switch Setting
When you use the A-626 / A-628 , You should set the I/O address and voltage range
first . you can configure output voltage of each channel and I/O address by jumper and
switch.
The position of jumper please refer the section 2.3 A-626 / A-628 layout
