Command Line Operation
Control Programmer’s Guide (Code Structure and Examples)
This section is designed for programmers who wish to create their own control
programs using the command code. All PureLink digital Matrix Routers provide a
simple character stream control used by external control devices attached to a
PureLink device. Command codes are used primarily for control, during system
installation and setup, and for diagnostic purposes.
Command code is a set of alphanumeric characters that combine to form control
commands. Command code strings are entered into a terminal emulation
program (such as windows HyperTerminal) running on an external control device.
The control device (PC, third-party controller) sends the commands to the
system. Control devices must be able to send and receive ASCII or HEXA code
via an RS-232 or Ethernet port.
Command Code Formats
A command code is a series of command characters and numbers used to send
commands to the system. Commands include basic formulas for creating and
disconnecting switches, as well as for verifying the status of switches and other
functions.
In a command code, each character is either general command (e.g, C for
connect) or an identifier that indicates what the following number designates (e.g,
“O” and the number following it designates an “Output number”). The command
code *255CI01O01! Can be interpreted as follows: (*) Starting the command
code (255) Router ID is 255 (C) Create connection on (I01) Input 01 to (O01)
Output 01 (!) take the command. For a complete list of command characters and
their functions, see page 67.
Ack value (Acknowledge value: Response from Pure Link device) will be echoed
back to the terminal screen as the unit accepts them. When a command is
successfully executed, all of the characters appear containing the character “s”
which stands for status. For example;
Ex 1) Command (Connect Input 1 to Output 1)
*255CI01O01!
Ack value
*255sC I01O01!
