dl2000-kfx dh+ to dh+
DH+ to DH+ Bridging
The DataLink DL2000-KFX contains two serial protocols and is software configurable for either standard DF1 or bridging modes. Standard DF1 mode is used to provide a serial interface to DH+ and is suitable as an alternative to Allen-Bradley's serial interfaces to DH+, like the A-B 1770-KF2. Bridging mode is designed to enable the DL2000-KFX to be used in pairs to bridge local and remote DH+ networks.

The bridging serial protocol can be used for DH+ to DH+ network bridging and for DH+ network band width expansion. This unit is capable of point-to-point or mulit-drop communications between local and remote DH+ networks. DataLinks are typically used in pairs to enable communications between multiple contiguous stations on separate DH+ networks. The -KFX accepts local DH+ message commands addressed to any DH+ sation within a configurable address range and passes them on to a -KFX on a separate DH+.

Bandwidth Expansion:
Doubles the bandwidth of a single busy DH+ by splitting it into two.
