PSS 5000 – Hardware Configuration Guide
Selecting the CPU Board and Interface Modules
1 How to Select the Correct Hardware
Overview Before a PSS 5000 can be installed on a site, the correct Hardware Interface
Modules (HIMs) must be selected. The method to select the correct HIMs and
an example of how to connect the devices and HIMs together are provided in
the following topics:
• ‘1.1 Selecting Hardware Interface Modules (HIMs) and CPU Board’ on
page 4
• ‘1.2 A Worked Example of How to Select HIMs’ on page 5
1.1 Selecting Hardware Interface Modules (HIMs) and CPU Board
To select the correct
HIMs for the PSS 5000
This procedure describes how to obtain the information necessary to select the
correct type and number of HIMs.
Note: If your forecourt devices, protocols or interfaces do not match the refer-
ence tables, contact support@doms.dk to help provide a solution.
1. Make a list of all the devices on the forecourt that you want the PSS 5000
to control.
To help you create this list, there is a form at the end of this documentation.
2. Look at the POS and find out which type of interface connection exists be-
tween the POS and the PSS 5000:
• If the connection is a serial interface, use the HIM hardware table
(‘3.8 HIM Details and Interface Types’ on page 30) to select the cor-
rect DSB module for the interface type. Continue to Step 3.
• If an Ethernet interface is used, go to Step 3.
3. Use the Manufacturer/Protocol tables (see ‘2 Device Manufacturers and
Device Protocols Used’ on page 10) to see which protocol each device us-
es, or is most likely to use. Write this in the list opposite each of the devices.
4. Use the Protocol/HIM tables (see ‘3 Device Protocols and Associated
HIMs’ on page 17) to select the HIMs for the actual Protocol/physical in-
terfaces the devices use.
Note: If your actual Protocol/physical interface combinations are not listed
in the tables, contact support@doms.dk for a solution.
5. Use the connection information provided for each HIM (see ‘3.8 HIM De-
tails and Interface Types’ on page 30) to determine how many of each type
of HIM you require.
6. Use your list to see how many different protocols are used. From this, de-
termine how many ports you must use on the CPU board.
Each protocol type requires a separate port on the CPU board.
Note: If you require support for more devices/port than is specified, con-
tact support@doms.dk.
7. Use the information from Step 5. and Step 6. together with the information
in ‘4 PSS 5000 CPU Board and Cabinet Specifications’ on page 35 to help
you decide which CPU board and cabinet to select for the PSS 5000.
8. Use the information in ‘5 PSS 5000 Accessories List’ on page 38 to select
