1.17. Communications
The communication interface may differ according to the user’s hardware. The Solo Guitar
Absolute Feedback 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 Guitar Absolute Feedback 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.
For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.
1.17.1. 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.
