4.11. Communications
The communication interface may differ according to the user’s hardware. The Gold Bell can
communicate using the following options:
Standard EtherCAT
G-BEL XXX / YYY S X G-BEL 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 Bell Communication Options
For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.
Note: When the EtherCAT is connected, and FoE in operation, the USB cable connection
must be disconnected.
4.11.1. RS-232 Communication (J2)
RS-232 communication requires a cable connected from the Gold Bell to a serial interface on
the PC. The interface is selected and set up in the Elmo Application Studio (EAS) software.
RS-232 communication of the Gold Bell is at the TTL logic level. It requires an RS-232 Line
Driver/Receiver in order to translate the TTL logic level to the standard RS-232 voltage level.
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.
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
