Verify the GS4 drive RS-485 connection to PC/Laptop computer through one of the GS4 RS485
ports using an RS-485 port connecting cable (RJ45). Alternatively you can link to a PC USB port
through a USB-485M (P/N USB-485M) adapter communication converter normally used to link
RS485 to a USB supported device (See Chapter 5 for discussion on GS4 drive communications).

Ethernet connectivity for EtherNet/IP communication is possible with optional communication
card # GS4-CM-ENETIP. Ethernet connectivity for Modbus TCP communication is possible with
optional communication card # GS4-CM-MODTCP. ZL-RJ12-CBL-2 can also be used between the
USB-485M and the GS4. Refer to “Appendix B: Optional I/O and Communication Cards” for
details.
For the 2-wire cable (RJ12 to flying leads) included with the USB-485M: Red wire plugs
into terminal SG+ on the drive. Green wire plugs into SG- on the drive. Also, the included
6-conductor RJ12 cable connects the USB-485M directly to the RS485 RJ45 ports on the GS4. (The
drives' RJ45 ports can accept 6-conductor RJ12 connectors).
