The module can operate in several different modes with each port acting 
independently. The configuration of each port's driver determines its mode. The 
following topics describe these modes. 
 

 

3.1 Data 

Flow 

The following topics describe the flow of data between the pieces of hardware 
(ASCII device and ProLinx Module). Each application port on the module is 
configured independently to interface with serial communication devices. The 
sub-sections that follow describe the three possible types of communication 
devices that can be attached to application ports: receive-only, transmit-only, and 
transmit-receive mode. 

 

3.1.1 Receive-Only 

Mode 

A port on the module configured to function in receive-only mode is set up to only 
receive data from some sort of ASCII device. In this mode, the ProLinx module 
will never transmit data back to the ASCII device. Any data received from the 
ASCII device is passed from the receiver driver (Rx Driver) to the ProLinx 
module's internal database (Rx Data). The following illustration shows the flow of 
data on a port configured for receive-only mode.
