Connection Guidelines
• Always connect analog signals using shielded, twisted pair cables. Unshielded cables
may lead to values outside the specified tolerance limits in environments subject to heavy
noise.
• Connect the cable shield to functional earth ground immediately after the cables enter the
control cabinet.
• Connect the cable shield to a shield bus if you are not using a closed control cabinet.
REM-11100 Getting Started Guide | © National Instruments | 9
Page 10
• NI recommends using the NI Remote I/O Shield Set for optimal shield connection.
• Make sure that devices you connect to the REM-11100 are compatible with the module
specifications.
• Push the wire into the terminal when using a solid wire or a stranded wire with a ferrule.
• Open the terminal by pressing a screwdriver into the spring lever when using a stranded
wire without a ferrule.
