CHAPTER 2
Operating Modes
Your OIT can be programmed to operate in one of three operating modes: Interactive,
Block, or Network. These modes affect how the OIT sends data to and receives data from
the host controller. This chapter explains the differences between the three operating
modes. Refer to Chapter 1: OIT Configuration for information on how to change the
operating mode.
Interactive Mode
In Interactive mode, the OIT immediately sends data to the host controller. For example,
pressing the OIT’s 1 key sends the ASCII character 1 to the host controller. Interactive
mode is most often used in applications that require simple one-key responses from the
OIT.
If local echo mode is enabled, any ASCII characters sent to the host controller are also
displayed on the OIT. When the cursor reaches the end of the current display line,
additional characters overwrite the character in the last column.
The following table lists the behavior of each OIT key in Interactive mode.
