Serial (RS232/USB) Operation
166 Advanced Digital Motor Controller User Manual V2.0 July 8, 2019
Serial Port Configuration
The controller’s default serial communication port is set as follows:
• 115200 bits/s
• 8-bit data
• 1 Start bit
• 1 Stop bit
• No Parity
Communication is done without flow control, meaning that the controller is always ready
to receive data and can send data at any time.

FIGURE 14-1. DB25 and DB15 connectors pin code locations
When used in the RS232 mode, the pins on the controller’s DB15 or DB25 connector (de-
pending on the controller model) are mapped as described in the table below

Connector RS485 Pin Assignment
When used in the RS485 mode, the pins on the controller’s DB15, DB25 or DB9 con-
nector (depending on the controller model) are mapped as described in each controller’s
datasheet.
Setting Different Bit Rates
It is possible to set RS232 and RS485 bit rate to lower values. This operation cannot be
done while the controller is connected via RS232 or RS485. Beware that once the bit rate
is different than the default 115200, it will no longer be able to communicate with the PC
utility if serial connection is used. From the Console, send the following commands:
^RSBR nn
where nn =
