I am sending hardcoded values to a remote instrument via TCP/IP in Simulink. However, I keep getting the error: 'Error evaluating registered method 'Start' of MATLAB S-Function 'stcpipsb' in 'TestSend2/TCP//IP Send'.' What could be causing this? What configuration parameters might I need to change?

In case anyone else is looking for answer - the TCP/IP blocks requires a server to be running with exact port available.
So running the command "echotcpip('on',50000)" before running simulation will get rid of the error when you are working on one computer and you don't have the actual server available. Note: 1) either the command can be added in some simulink model callback (preload/init) 2) change the port number to match with your need
Hope it helps...
