Figure 21 - SMT6060-TCPIP SMT363 Configuration as Network Interface
Note: This technique can be used to run the Diamond server on a notebook computer connected to the
Ethernet of a stand-alone carrier board.
The net2dsp application implements a simple server that accepts connections from network applications.
The network application then sends instructions to the server. The instructions could be:
1. Write data to a comport of the SMT363
2. Read data from a comport of the SMT363
All transactions take the form of a data structure like this:
typedef struct {
int device;
int cmd;
int bytes;
} command;
“device” refers to which Diamond channel (and indirectly which comport) should be used for the
operation.
“cmd” indicates read or write from device. (0 = read, and 1 = write)
“bytes” selects how many bytes to read or write.
6.15. CONFIGURING THE HOST
The host application is build into the Sundance host driver software. You activate the host functionality
by making a number of entries into the registry of the machine where you wish to run the host software.
The key
HKEY_LOCAL_MACHINE\SOFTWARE\SmtDrv\ethernet
