4.3 I/O SETTING
It is necessary to define in the receiver the amount of data that will be transmitted to the bus. Both the
size of bytes to be sent and those to be received are configured through the E2PROM memory. These
data are configured at the factory according to the needs of the customer.
The memory locations where the data is stored are (page 1):
0xA9
Number of digital output channels
0xAA
Number of analog output channels
0xAC
Number of digital input channels
0xAD
Number of analog input channels
0xAE
Set to 0x01 to activate auxiliary input (SCC 1 byte)
The
“number of digital channels” corresponds to the resulting bytes of the channels, bit by channel
(digital channels/8). Each analog channel is one byte so the
“number of analog channels” corresponds
to the quantity of analog channels.
Example:
If we use 24 digital channels and 6 analog channels we will have the follow:
Number of digital output channels = 24/8 =
3
Number of analog output channels =
6
