2-2 Installation
SCANport Cables
When selecting the SCANport cable to connect the 1203-GU6
module to the SCANport product, you need to:
• Use an Allen-Bradley SCANport cable. Refer to the table below.
• Use less than 10 meters (33 feet) of cable between the SCANport
product and adapter.
• Keep SCANport cables away from high power cables to guard
against introducing noise into your system.
DeviceNet Cables
The 1203-GU6 module comes with either one 5-pin connector or a
5-pin and 10-pin connector. A drop line connects a node, such as an
adapter, on the DeviceNet cable system to the DeviceNet trunk. When
selecting a drop line, you need to:
• Select either a 5-pin connector or a 10-pin connector for the
cable. (Both are included with the 1203-GU6 module).
– Use the 5-pin connector if you are using a DeviceNet drop
cable configuration.
– Use the 10-pin connector if you are using a daisy-chaining
configuration.
• Determine limitations of the trunk and drop cables. Refer to the
following table.
For more information on DeviceNet cables and cable systems, refer to
the DeviceNet Cable System Planning and Installation Manual,
