E.3 Function Calls
The function calls described in this section are used with all RabbitNet peripheral cards,
and are available in the RNET.LIB library in the Dynamic C RABBITNET folder.
Resets, initializes, or disables a specified RabbitNet port on the master single-board computer. During
initialization, the network is enumerated and relevant tables are filled in. If the port is already initialized,
calling this function forces a re-enumeration of all devices on that port.
Call this function first before using other RabbitNet functions.
PARAMETERS
portflag
is a bit that represents a RabbitNet port on the master single-board computer (from 0 to the
maximum number of ports). A set bit requires a service. If portflag = 0x03, both RabbitNet ports 0
and 1 will need to be serviced.
servicetype
enables or disables each RabbitNet port as set by the port flags.
0 = disable port
1 = enable port
RETURN VALUE
0
Returns an address index to device information from a given physical node address. This function will
check device information to determine that the peripheral card is connected to a master.
PARAMETER
pna
is the physical node address, indicated as a byte.
7,6—2-bit binary representation of the port number on the master
5,4,3—Level 1 router downstream port
2,1,0—Level 2 router downstream port
RETURN VALUE
Pointer to device information. -1 indicates that the peripheral card either cannot be identified or is not
connected to the master.
