This LLB has the following vis

Init Switch: This VI uses inputs for the Visa Resource and the boolean Answerback enabled and initializes the switch to a known 
state. Outputs are the boolean Device Found and the identifier response.

Looping Eg: This example VI uses inputs for Matrix (usually 0 for mainframes), # of mods  and # of relays. Then starting with
Mod 0 Relay 0 it will loop through the relays using a Multiplex command (eg. X0 0 0 to X0 3 7).

MTX Command Format: This VI takes inputs of the matrix, module and relay number and appends it to the command integer input.
0= clear (C), 1 = status(S), 2 = multiplex(X), 3 = unlatch(U) and 4 = latch(L).

Because the VIs use the Visa Resource you will be able to communicate with the switch using LAN, GPIB or Serial
communication. 

If the drop down menu for the Visa Resource In doesn't show your LAN connection you will need to go into NI MAX and
add a new LAN Resource. This is usually done by Manual Entry of a Raw Socket with the IP Address and Port 
configured for the switch (defaults are 10.0.0.144 and port 8080 or 8081). Your network administrator may need to 
assist with this.

Any responses received from the Cytec switch will be terminated with either a new line(\n or 10 or Ox0A) for LAN or a 
carriage return (/r, 13, Ox0D) for Serial communication or an EOL for GPIB. If Answerback is on the response will be followed 
by an Answerback character and a terminator also. So if Answerback is on and your IO Session is configured to read until
the terminator is received you will need to read twice. If your IO Session is configured to read until all of the bytes
requested are received or timeout then you will need to either know the number of bytes to expect or wait for the 
timeout to occur.
