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 191.
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 Encoder Module contains its own Microcontroller and firmware in Flash. The
Encoder’s MCU communicates 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 131.
