-dSpeed
Where speed is the data rate of the PCX 20
0 for 2.5Mbs (default value)
1 for 1.25Mbs
2 for 625Kbs
3 for 312.5Kbs
4 for 156.25Kbs
-r Read and write packets in raw mode. This mode ignores the
protocol specification for ARCNET, to facillitate the operation of
devices using only the ARCNET hardware standard. The information
below is primarily for the benifit of higher level driver writers
intending to write a driver using the CCSARC driver in this
mode. |
Note 1: The SID, DID, msbcount and lsbcount fields in the ARCNET
packet diagram below will no longer be transmitted. It is up to the
higher level driver to add custom header information.
Note 2: The arcnet driver will not strip off header information
on incoming packets. The higher level driver must handle this
function. Also, as it is not possible for the Contemporray Control
Systems card to tell the CCSARC driver how long an incoming packet
is, then all incoming packets are assumed to be 512 bytes and it is
up to the higher level driver to determine the end of the packet,
and ignore garbage bytes after the end.

Example
To set up a MODBUS / MBSLAVE link between two Citect. Both Cards
are set up with I/O Port 0x2b0, the MODBUS ID is 80 and the MBSLAVE
ID is 81.
