PERIPHERAL DEVICES SOFTWARE DESCRIPTION
In the previous paragraphs are described the external registers addresses, while in this one there is
a specific description of registers meaning and function (please refer to I/O addresses table, for the
registers names and addresses values). For a more detailed description of the devices, please refer
to documentation of GMB HR168 + grifo^® Mini Module combination. In the following paragraphs
the D7÷D0 and .0÷7 indications denote the eight bits of the combination used in I/O operations.
RELAYS OUTPUTS
Staus of 8 digital relays outputs is set through 8 signals of 40 pin socket ZC1.
Please remark that signal driving relay OUT D2 can be connected either to signal MM PIN 16 or to
signal MM PIN 30 according to the connection of jumper J10:
J10 conncted in 3-4 -> OUT D2 driven by MM PIN 30
J10 connected in 4-5 -> OUT D2 driven by MM PIN 16
When the signal of socket ZC1 is set to logic state low (logic 0), the corresponding output is actived
(relay contact is connected to its common pin), viceversa when the signal is set to logic state high
(logic 1) the corresponding output is deactived (relay open).
As previously said, LEDs LD1÷8 provide a visual indication of digital outputs status (LED ON =
output actived).
Summarizing, the correspondance is:
MM PIN 29 , OUT A1 ->
MM PIN 28 , OUT A2 ->
MM PIN 27 , OUT B1 ->
MM PIN 26 , OUT B2 ->
LED LD1
LED LD2
LED LD3

MM PIN 14 , OUT C1 ->
MM PIN 15 , OUT C2 ->
MM PIN 18 , OUT D1 ->
(see above) , OUT D2 ->
LED LD5
LED LD6

SERIAL LINE
The signals used are the ones called TxD and RxD in figure 4, connected to signals MM PIN 9 and
MM PIN 10 of 40 pins socket.
