USAGE:
RELATED COMMANDS:
EXAMPLES:
NOTE: When the IH command is given, the controller initializes an ARP on the slave device
before opening a handle. This operation can cause a small time delay before the controller
responds.
NOTE: The HC command is recommended over the IH command for establishing a connection
with slave controllers because it is a simplified process.
