Communicating With An Ascii Introduction; Device Connect The Ascii Device - Rockwell Automation Logix 5000 Series Programming Manual

Introduction
Connect the ASCII device
Communicating with an ASCII device
You can exchange ASCII data with a device through the serial port of the
controller. For example, you can use the serial port to:
• Read ASCII characters from a weigh scale module or bar code reader.
• Send and receive messages from an ASCII triggered device, such as a
MessageView terminal.
Firmware revision 3.1 and later of the 1756-EWEB EtherNet/IP Web Server
module supports the controller serial port and a socket interface that lets
Logix 5000 controllers exchange ASCII data using TCP or UDP socket
services.
To connect to the ASCII device, use these steps.
1. On the serial port of the ASCII device, determine which pins send
signals and which pins receive signals.
2. Connect sending pins to corresponding receiving pins and attach
jumpers.
