2-2 Network Configuration Restrictions

CompoBus/D communications are designed to meet a wide range of applications by providing a choice of baud rates and allowing different combinations of T-branch and multi-drop connections. The restric- tions of CompoBus/D communications that are required to enable the various communications possibi- lities are described here.

2-2-1 Baud Rate and Communications Distance

The maximum length of the CompoBus/D communications cables is restricted by the baud rate and the type of cable used. The three types of restrictions on CompoBus/D communications cable length are as follows:

SMaximum network length

SDrop line length

STotal drop line length

Be sure to design and configure a Network that meets the conditions provided below to ensure reli- able communications.

Note Thick Cable (5-wire): DCA2-5C10 (100 m)

Thin Cable (5-wire): DCA1-5C10 (100 m)

HMaximum Network Length

The length of the Network is longest at either the distance between the two most distant nodes or at the distance between the Terminating Resistors.

There are two types of cables: Thick Cables and Thin Cables. The cable thickness affects signal deteri- oration. The maximum length of the Network therefore depends on the type of cable used as shown in the previous table.

The following restrictions apply to Networks in which both Thick and Thin Cables are combined.

Thick Cable length + Thin Cable length x 100 m

 

 

 

250 kbps

Thick Cable length + 2.5

Thin Cable length x 250 m

 

 

 

125 kbps

Thick Cable length + 5.0

Thin Cable length x 500 m

 

 

 

HDrop Line Length

The length of the drop line is measured from the point in the trunk line where the original branch was made to the end of the branch. The maximum length of a drop line is 6 m. It is possible to make a second- ary branch from a drop line.
