Installing the 16-Relay Card
Selecting the I/O Address (ME63/ISA)

 Tips:

Due to its obsolete technology, the ME63 ISA card is no longer available from Dionex. However, ME63 (ISA) cards may still be used in the field. Therefore, refer to the installation instructions below if necessary.

This card is not supported under Windows Vista or later.

 

The DIP switch block (Dual Inline Package) on the pump control card configures the I/O Address of the relay card.

Starting from the base address, the relay card requires four addresses, but no interrupts. The I/O base address is set to 300H (default). Only modify the base address if there are address conflicts with other Sharable Devices; for example, with the pump control card.

For information about how the eight switches are assigned to the binary digits, refer to the table below:

 

Switch

Default

Function

1

ON

8-digit

2

ON

16-digit

3

ON

32-digit

4

ON

64-digit

5

ON

128-digit

6

OFF

256-digit

7

OFF

512-digit

8

ON

1024-digit

 

An open switch (OFF) corresponds to binary 1; a closed switch (ON) corresponds to binary 0. According to the table, the presetting on the relay card corresponds to the following base address:

256 + 512 = 768 (decimal) = 300H (hexadecimal).
