3.12. Communications

The communication interface may differ according to the user’s hardware. The Hornet and Bee

can communicate using the following options:

a. RS-232, full duplex

b. CANopen

RS-232 communication requires a standard, commercial 3-core null-modem cable connected

from the Hornet or Bee to a serial interface on the PC. The interface is selected and set up in

the Composer software.

In order to benefit from CANopen communication, the user must have an understanding of the

basic programming and timing issues of a CANopen network.

For ease of setup and diagnostics of CAN communication, RS-232 and CANopen can be used

simultaneously.

3.12.1. RS-232 Communication

Notes for connecting the RS-232 communication cable:

• Connect the shield to the ground of the host (PC). Usually, this connection is soldered

internally inside the connector at the PC end. You can use the drain wire to facilitate

connection.

• The RS-232 communication port is non-isolated.

• Ensure that the shield of the cable is connected to the shield of the connector used for

RS-232 communications. The drain wire can be used to facilitate the connection.
