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.
