handling may cause damage to your module. Be sure there are no shipping and handing damages on the module before processing. After opening the card module carton, extract the system module and place it only on a grounded anti-static surface component side up. Again inspect the module for damage. -
Page 14: Jumper And Dip Switch Description
Jumper and DIP Switch Description You can change the ACL-6128's channels and base address by setting jumpers and DIP switches on the card. The card's jumpers and switches are preset at the factory. Under normal circumstances, you should not need to change the jumper settings. A jumper switch is closed (sometimes referred to as "shorted") with the plastic cap inserted over two pins of the jumper. - Page 15 Figure 2.2 Default Base Address Setting I/O port address(hex) 200-20F 210-21F (*) 2C0-2CF 300-30F 3F0-3FF Table 2.1 (*) : default setting ON : 0 X : don't care OFF : 1 Note : A3, ..., A9 correspond to PC bus address lines. How to Define a Base Address for the ACL-6128 ? The DIP1 to DIP7 in the switch SW1 are one to one corresponding to the PC bus address line A9 to A3.

Page 16: Selecting D/A Range And Functions
Selecting D/A Range and Functions There are two facts will effect the output voltage of ACL-6128 : reference source and output range . 2.6.1 Reference Source Setting The ACL-6128's D/A converter reference voltage source can be internal generated or by external reference voltage from the Reference Voltage Input (REF.IN) of connector CN1 and CN2. -
Page 17: Output Range Setting
Internal -5V Channel No. Internal -10V ( Default) Figure 2.4 Internal Reference Voltage Setting If users choose the external reference, both AC and DC voltage sources can be used by the external reference, and the maximum input voltage is +/- 10V. The voltage sources can be input through Pin 3 of CN1 and CN2 connectors. -
Page 18: Summary
2.6.3 Summary According to the reference source and output range settings, users can follow the below table to configure the output voltage of CH1 and CH2 for different situations. ( JP1, JP3, and JP5 are for CH1; JP2, JP7, and JP9 are for CH2) Jumper JP3 for CH1 JP1&JP5 for CH1... -
Page 19: Current Sink Range Setting
Current Sink Range Setting Not only the voltage output, the ACL-6128 also provide either 0-20mA or 4-20 mA current sink. In order to use the current sink range, you must set the output voltage to unipolar. The jumper JP6 is corresponding to CH1, and JP10 is used with CH2. -
Page 20: Connector Pin Assignment
Connector Pin Assignment The ACL-6128 comes equipped with two D-9 female connectors - CN1 and CN2. Both of the CN1 and CN2 are located at the rear plate. CN1 is used for outputting connection of CH1, CN2 is for CH2. Each of the connector's pin assignment is specified as follows: Legend : V.OUT : Analog Voltage Output... -
