1 INTENDED PURPOSE OF THE BOARD
The board PA 7300 provides the personal computer (PC) with an asynchronous
serial interface for the communication with external devices.
The operating mode depends on the version of the basic board PA7300 and on
the SI modules installed.
The operating modes have different features regarding electromagnetic
compatibility.
The board is to be used in a free PC ISA slot. The PC is to comply with the EU
directive 89/336/EWG and the specifications for EMC protection.
Products complying with these specifications bear the mark.
The board supports serial communication through an asynchronous serial port.
The following table shows the recommanded combinations of the basic board
PA7300 with the following SI modules:

Connection to the peripheral
with a shielded cable, twisted in pairs.
Connect the peripheral cable so that the differential lines described in the
connector pin assignment with "+" and "-" are twisted in pairs.
Operating mode RS232: the signal lines are to be twisted in pairs with GND.
The housing of the peripheral connector
- is to be firmly screwed together with the shield of the cable
- is to assure a low-resistance connection (< 100 mΩ) between the shield and
the housing of the PC.
The shield of the cable is to be earthed on both ends.
The use of the board according to its intended purpose includes observing all
advices given in this manual and in the safety leaflet. Uses beyond these
specifications are not allowed. The manufacturer is not liable for any damages
which would result from the non-observance of this clause.

1.1 Limits of use
The use of the board in a PC could change the PC features regarding noise
emission and immunity. Increased noise emission or decreased noise immunity
could result in the system not being conform anymore.
If the basic board PA7300 is used with galvanically separated SI modules,
then the creeping distance of 3.2 mm to the RS232 peripheral lines which are
not galvanically separated is not ensured anymore.
Our boards are not to be used for securing emergency stop functions.
The emergency stop functions are to be secured separately.
This securing must not be influenced by the board or the PC.
Make sure that the board remains in the protective blister pack until it is used.
Do not remove or alter the identification numbers of the board.
If you do, the guarantee expires.

5.3 Configuring the board with ADDISET
5.3.1 Load ADDISET
In the directory ADDISET, type <ADDISET>.
The parametering program for the board PA 7300 is loaded.
ADDISET lists automatically all the plug & play ADDI-DATA boards which
are plugged in your PC. They appear in the board list in the order in which they
have been detected by the chain of characters identifying the board. Port 1 is
detected before Port 2.
Make sure that ADDISET has detected all the boards.
You move the cursor on the port you wish to configure. It is highlighted. Klick
on the button Configuration and the following dialog box appears:
Fig. 5-5: Dialog box Configuration
IMPORTANT!
When configuring a Plug & Play board make sure that no other
Plug & Play board is active.
Network boards: a plug & play network board should not be coupled to a
network, when an ADDI-DATA plug & play board is being configurated.
This may cause the PC being unstable.
