ETHERNET PORT
The Ethernet port is connected to a switch or a hub in LAN. (If your Marquee unit has two Ethernet ports, please
use the one below SP2 port;
DO NOT USE
the other Ethernet port).
The Marquee is generally programmed using the Ethernet port. (But, under certain cases as mentioned later, serial
port SP1 may be used). In addition, the Marquee may communicate with PLCs over Ethernet when using Ethernet
protocols such as Ethernet/IP, Modbus TCP/IP, etc.
The Factory-default IP settings are:
IP Address: 192.168.0.1 and Subnet Mask 255.255.255.0
The IP address of the Marquee is displayed on Power up. The user can change the IP address using the Marquee
programming software (see section 3.4)
If you have trouble communicating over Ethernet …
If, for some reason, you are unable to communicate over Ethernet, you can try communicating to the
marquee over the Serial port (SP1) instead. The latter allows you to change IP address, download a new
user program, or upgrade Marquee application (firmware) over the serial port.
To communicate with the Marquee using the Programming software running on a PC, follow these
steps:
1. Turn off the power being supplied to the unit, and wire the serial port of PC to the serial port
SP1
on
the Marquee’s Controller board. The wiring diagram is as shown below
(DO NOT remove the jumper
between pins 1-2 on the SP1 connector (refer to Fig. 2.3.1 for SP1 pin-outs)
