3.2.1 OPERATING INSTRUCTIONS - NVTAKE (OBSOLETE)

INVOCATION:

NVTAKE [H | U | V | E | R] [1|2] [9600|38400]

Where argument 1 is the router control protocol from the following list:

H = Horiz on control protocol

U = Utah Scientific

V = Vistek

E = ESBus

R = BTS

and argument 2 is the communications port, default = COM1. Argument 3

is the serial portss baud rate. Default = 9600 Invoking NVTAKE with no

arguments displays the programs syntax summary.

Figure 3.1 illustrates the basic NVTake screen.

OPERATIONS

The various functions of the program are invoked with function keys from

the following list:

F1 Send a single take

F2 Send a salvo of takes

F3 Change to level to which the controller sends commands

F4 Query a single crosspoint (Vistek protocol only)

F5 List 10 sequential crosspoint connections. (Vistek protocol only)

F6 List all destinations connected to a single source. (Vistek protocol only)

F3 CHANGE ROUTER LEVEL

The F3 function key allows changing the level to which the controllers

commands are issued. The level IDs of most routing protocols are

numeric. Vistek uses the alpha characters A-Z. Again, point-to-point

connections are addressed on level one. Connections involving multiple

destinations are addressed on level two.
