3.5.8. Communication
The communication interface may differ according to the user’s hardware. The Solo Trombone
can communicate using the following options:
• RS-232, full duplex
• CAN
RS-232 communication requires a standard, commercial 3-core null-modem cable connected
from the Solo Trombone to a serial interface on the PC. The interface is selected and set up in
the Composer software.
In order to benefit from CAN communication, the user must have an understanding of the basic
programming and timing issues of a CAN network.
The CAN interface is not isolated.
For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.
3.5.8.1. RS-232 Communication
To connect the RS-232 communication cable
1. 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.
2. The RS-232 communication port is non-isolated.
