4.11. Communications
The communication interface may differ according to the user’s hardware. The Gold Hornet can
communicate using the CAN open option:
Standard EtherCAT
G-HOR XXX / YYY S X G-HOR XXX / YYY E X
CAN EtherCAT
USB 2.0 USB 2.0
Ethernet RS-232 (TTL Logic Level)
RS-232 (TTL Logic Level)
Table 20: Gold Hornet Communication Option
For ease of setup and diagnostics of CAN communication, RS-232 and CAN may be used
simultaneously.
When the EtherCAT is connected, and FoE in operation, the USB cable connection
must be disconnected.
4.11.1. RS-232 Communication (J2)
The Gold Whistle provides RS-232 with TTL voltage level (Refer to the voltage level in the
technical specification in Section 5.7: Communications). Therefore, to implement standard RS-
232, you must add a RS-232 Line Driver/Receiver on the integration board in order to translate
the TTL logic level to the standard RS-232 voltage level.
The following table describes the Gold Whistle RS-232 pinout:
Pin (J2) Signal Function
45 RS232_Rx RS-232 receive (TTL logic level)
48 RS232_Tx RS-232 transmit (TTL logic level)
46 RS232_COMRET Communication return
