Special Addresses; Address $F0; Defined Commands (Master To Slave); Echo (A) - Ametek 5920 UHP User Manual

Special Addresses

Addresses $F0 through $FF are reserved for special functions with address
$F0 used as a broadcast address.

Address $F0

Node address $F0 is used as a single point address (i.e., it is intended for use in
configurations with a single slave). The slave will respond to all messages with
node address $F0. You must be careful to prevent multiple slaves from receiv-
ing commands with the broadcast address as this will cause a bus contention.

Defined Commands (Master to Slave)

The commands that can be issued from the master are listed in Figure 2-18.

munication. Any text transmitted by the master is returned.
