B-ACS RS232C Serial Link
Installation Manual Version 001 BRUKER 95 (167)
B-ACS RS232C Serial Link 11.5
In its standard configuration the B-ACS sample changer is able to handle 60 or
120 samples, and is controlled via a RS232C serial link. The sample changer soft-
ware defines the transmission mode of the RS232 channel as follows:
8 data bits (data bit 8 = „1“)
2 stop bits
no parity
System Parameters 11.5.1
The following system parameters have to be adjusted or taken in consideration:
1. Check the DIL switch setting on the BMP SIOA board. Switch S1 serves for
setting the I/O address of the SIO board. It should be set at E. The transmis-
sion baud rate can be set with switch S2 according to the following table:
The standard value is 9600 baud, i.e. position 9. The location of the switches are
shown in the implementation diagram, figure 11.28
 (Factory settings: S1 = „E“, S2
= „9“).
