About terminators
Electrically stabilize your DeviceNet communication with terminating
resistors.
Sealed-style terminators (round media)
Male and female sealed terminators have gold plated contacts for corrosion
resistance.
Unsealed-Style terminator (round and flat media)
An open-style terminator is suitable for use with:
•
DeviceBox taps
•
open-style plugs or taps
•
KwikLink open-style Insulation Displacement Connectors (IDC)
IMPORTANT
You must terminate the trunk line on each end with a
121ohms, 1%, 1/4W or larger resistor.
