Chapter 2

Configure the 1769-ASCII Module

8.

Configure channel parameters under the channel tab. 

Each channel can be configured for 4…200 characters. For Simultaneous 
Mode, the sum of Channel 1 and Channel 2 for Receive and Transmit 
characters cannot exceed 200 bytes.

9.

Module's RPI can be configured through Connection tab.

RPI can be configured in multiples of 0.5.
