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-HORXXX/YYYSX G-HORXXX/YYYEX

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
