Control is via an Ethernet interface independently to each module. Controlling software can be run from a PC anywhere on a network to control and interrogate the status of each module of the unit. This external interface is 10BASE-T/100TX Ethernet with auto sensing.

Connecting to AROW’s Control and Status Port

Connections to AROW’s control and status ports are made with a standard TCP/IP socket.  Note that only one application can open a socket at a time so if a second application attempts to create a socket connection it will be refused.

When the application has finished controlling AROW, it should release the socket connection so that another application can have access to it.

Protocol

Messages between AROW and the controlling application should follow a request/response model. The application should request that a command be executed or that a status word be collected. AROW responds with the executed command or the status requested.

Status requests

Only one status request should be made at one time. The application should wait until the status of the request has been received before moving on to the next command or status request.

Commands

Only one command should be sent at one time. The application should wait until the response to the command has been received before moving on to the next command or status request.

Windows GUI

WinAROW is a simple Graphical User Interface application that allows point and click control of each module. It can be found on the supplied delivery medium (usually CD or USB stick).
