USB communication

Use USB only for conﬁguration, monitoring and troubleshooting. USB is not a reliable

communication method when used in a electrically noisy environments and communica-

tion will not always recover after it is lost without unplugging and replugging the connec-

tor, or restarting the controller. Always prefer RS232 communication when interfacing to a

computer. USB and CAN can operate at the same time on the GBL2660. Plugging USB to

a com puter will not disable the CAN interface.

RS485 Communication

The FBL2360 has a half-duplex RS485 interface. Two signals are present on the 25-pin

DSub connector for connecting to RS485 networks. Connecting these two wires with the

correct polarity is all that is needed to establish a connection. The RS485+ is the positive

signal and RS485- is the inverted signal. Once enabled, the RS485 can be used to commu-

nicate data under the Modbus protocol, or Roboteq’s native serial commands.

Ethernet Communication

Ethernet communication is only available on the E versions of the controller. The con-

nection port is located on the top of the unit for easy and rapid access. Communication

occurs via TCP/IP. Commands can be in Serial over TCP and Modbus TCP. Serial over TCP is

the preferred method to access all native commands.

Two LEDs are present on the Ethernet jack, as shown in Figure 13. The left Yellow LED

will be On when operating as 100 Mbps connection and Off when as 10 Mbps. The right

Green LED will blink when data activity is present.

Status LED Flashing Patterns

After the controller is powered on, the Power LED will tun on, indicating that the controller

is On. The Status LED will be ﬂashing at a 2 second interval. The ﬂashing pattern and color

provides operating or exception status infor mation.
