AX2500/2850 Motor Controller User’s Manual 91
Establishing Manual Communication with a PC
and Installing the Utility” on page 159). The configuration file is set to use the COM1port.
You can easily change this setting to a different port from the program’s menus.
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 v1.7 02/01/05
s
The letter below the prompt message is a code that provides information on the hardware
and can be ignored.
On the AX3500, AX2850, or AX2550 with an Encoder module, this first prompt is immedi-
ately followed by a second one send by the MCU dedicated to the Encoder function:
RoboEnc v1.7 02/01/05

Entering RS232 from R/C or Analog mode
If the controller is configured in R/C or Analog mode, it will not be able to accept and recog-
nize RS232 commands immediately.
However, the controller will be “listening” to the serial port and will enter the serial mode
after it has received 10 continuous “Enter” (Carriage Return) characters. At that point, the
controller will output an “OK” message, indicating that it has entered the RS232 mode and
that it is now ready to accept commands.
Note that for improved safety, the RS232 watchdog is automatically enabled when entering
the RS232 in this way. See “RS-232 Watchdog” on page 98.
When reset again, the controller will revert to the R/C mode or Analog mode, unless the
Input Mode parameter has been changed in the meantime.
Data Logging String in R/C or Analog mode
If the controller is in the R/C or analog mode, immediately after reset it will send a continu-
ous string of characters (one character every 8ms, one entire string every 200ms) contain-
ing operating parameters for data logging purposes.
