AX500 Motor Controller User’s Manual 105
Establishing Manual Communication with a PC
COM1port. You can easily change this setting to a different port from the program’s
menus.
Note that starting with version 1.9, the Roborun PC utility also includes a Terminal Emula-
tion Console for communicating with the controller using raw data. See “Using the Con-
sole” on page 143.
In all cases, immediately after reset or power up, the controller will output a short identity
message followed by a software revision number and software revision date as follows:
Roboteq v1.9b 06/01/07
s
The letter below the prompt message is a code that provides information on the hardware
and can be ignored.
RS232 Communication with the Encoder Module
The contains its own Microcontroller and firmware in Flash. The Encoder’s MCU communi-
cates with the one on the main board of the controller. During normal operations, the two
MCUs exchange information as needed, transparently to the user.
During a short time at power up, however, the Encoder’s MCU will send data to the main
serial port.
The sent data is a separate prompt message which:
• Announces the presence of the encoder MCU
• Outputs its software revision and date
• Outputs a code identifying the module’s hardware ID
The serial port settings are described in “Serial (RS-232) Controls and Operation” on
page 101.
