CHAPTER 2

EX II 3000SP Controller

Communications

This chapter discusses the fundamentals of communicating with the EX II 3000SP controller. Firmware commands are usually issued by a driver or utility program on the host system, however developers can enter these commands directly.

This chapter:

Describes the controller default settings

Lists the recommended firmware commands for current development

Describes how to use each of these commands

References additional commands developers may need

The description of each command includes the command syntax, the default value, how the command works, and the expected response from the controller.

Controller Default Settings

This section describes the default communications parameters, data format, and operating mode settings for the EX II 3000SP controller.

Communication Parameters

The default operation of the EX II 3000SP controller is N, 8, 1 (no parity, 8 data bits, and 1 stop bits) at 9600 baud. It also can be programmed to work with even/odd parity, 8 data bits, and 1 or 2 stop bits.
