2.5 Installation on the PC-Interface Board
Fig. 4: Address selection on the M68-Interface board
For selection of the I/O-address, the board is fitted with a DIP-switch block (
D
ual
I
nline
P
ackage) as shown in fig. 4. The board occupies 4 addresses, starting at the selected base
value which is factory set at 318H. Under normal circumstances, this value need not be
changed unless operating in combination with network and/or other interface boards, the
addresses of which should be confirmed before installation.
Warning:
Ensure that the PC is off and the power cable disconnected before
attempting installation.
Important:
The interface board must be protected against static charge at all times. If
difficulty is encountered fitting the board into the PC, please contact the
Dionex Service.
Please note:
The board can be inserted in an 8-bit or 16-bit slot.

An open switch (OFF) indicates a binary "1", while a closed switch (ON) indicates a binary
"0". On the right, the values are converted into
hexadecimal
values. Determine the address by
adding the values. The default setting of the
UVD 170S/340S
interface board therefore has the
following base address:
8 + 10 + 100 + 200 =
318H (hexadecimal)
.
