7. The read/write head in the AS-i network

Basic setting

Parameters
I/O code [hex]
ID code [hex]
Extended ID2 code [hex]
ID1 code for coded value [hex]
Slave address (factory setting)

Addressing

The read/write head is addressed using an addressing unit (e.g. AC1144), the mas-
ter or the AS-i software of the host (the components must support the AS-i version
2.1).
Assign an address between 1 and 31.

Analogue value representation

For the AS-interface the read/write head is a slave having an analogue input with
the transmission protocol to the profile 7.4. If the master operates to the master
profile M3 or M4, it automatically detects the read/write head and supports the
profile 7.4.
For the analogue value transmission the profiles 7.3 and 7.4 are identical.
You can find the manual with details about the AS-i services to the profile 7.4 on
our website at:

Assignment of the data bits

In one transmission cycle the following data are transferred in data triples.

(static 0)
Additional information bits:
O = overflow bit (is set for the values 7FFF and 8000 hex, otherwise 0)
V = valid bit (is set for a valid value)
