ranslation of the
original instructions
Maximum communication performance is guaranteed by
using the specified cable (PXC75). The maximum communication
speed between the peripherals is 115,200 baud. If the cable speci-
fied is not used or if there are problems at installation, the control unit
transfer speed can be decreased (38,400, 9,600, 4,800 and 2,400
baud). The speed of the peripherals is set automatically.
Inputs cabling
Balancing is done with 4.7 kohm resistors at 5%, with 2.2 kohm for
Triple Balancing.
If it is necessary to use different balancing resistors, they can be set
up using the PXC2-Manager programming software.
The following values can be set via PXC2-Manager:
1K0,1K2,1K5,1K8, 2K2, 3K3, 3K9, 4K7, 5K6, 6K8, 8K2, 10K, 12K ohm
