Wireless ASCII Generic Serial Gateway
6201-WA-ASCII
Product Description
The ProLinx Wireless ASCII Generic Serial Gateway creates a powerful wireless connection between ASCII input devices. The module provides one ASCII configurable serial port.
The PWP modules offer one-to-one or one-to-many interconnect scenarios. Data is exchanged between devices and/or networks using a shared common database and an efficient but powerful wireless protocol. This common database provides the "backbone" communications for various field devices using different networks.
The ASCII protocol driver permits the module to interface to many ASCII devices. Each ASCII port on the module is configurable to send and/or receive ASCII strings, each supporting its own individual serial network.
Product Applications
The WA-ASCII module is the ideal solution for the many applications where wireless connectivity can be used to integrate an ASCII generic serial input device into a system. Applications for the module are found in most industries, including
-
Bar code scanner interfaces
-
Weigh scale interfaces
-
Legacy ASCII protocol connections
-
Terminal port emulation
-
Printer driver (alarm/status printer)
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration Data Area
This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.
ASCII Serial Specifications
The ASCII driver provides a powerful connection between the internal application database in the ProLinx unit and devices supporting serial ASCII communications (bar code scanners, line printers, legacy terminal based computer systems, etc).
The serial port on the gateway is user-configurable to support ASCII communications (Baud rate, Data Bits, Stop Bits, etc). The ASCII port can act as a Master (Send ASCII strings) or as a Slave(Receive ASCII strings), or both.
When configured to send data strings, the transmission of characters strings is easily accomplished by the placement of string data in the module's application database, followed by toggling of a transmit control word. When the ASCII Serial driver detects a change in the transmit control word, the string is sent out the port.
When configured to receive data strings, the module buffers the data until the termination condition is satisfied (as configured by the user) and the receive string is then copied into the module's application data space, with the actual character count value leading the ASCII string data.
The following table provides specifications for the configuration and functionality available on the ASCII serial ports:
