1. Note 1 If power supply specifications cannot be met with a single power supply when the current ca pacity of the Thick Cable exceeds 8 A even after the power supply location is modified use more than one communications power supply Note 2 In configuration 1 the power can be supplied in two directions to the trunk line as long as the current capacity of each is 8 A or less when using Thick Cable i e it is possible to have a configuration with a total maximum current capacity of up to 16 A 2 8 CompoBus D Communications Line Design Chapter 2 Note 3 Consider changing to Thick Cable to meet specifications if the current capacity of the Thin Cable exceeds 3 A when using Thin Cable for the trunk line Setting the Power Supply Location Determine whether or not the current can be supplied normally by finding the current capacity required by each node and the voltage drop in the cables to be used to provide power Calculate the values below in advance e The current capacity required by each node e The distance between the power supply and each node The current capacity of the 3G3MV PDRT1 SINV CompoBus D Communications Unit is approximately 20 mA Calculating the Power Supply Location There are two methods to find the best location of the communications power supply on the trunk line e Simple calculation from a graph e Calculation
2. CompoBus D Communications Line Design Chapter 2 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 e Maximum network length e Drop line length e Total drop line length Be sure to design and configure a Network that meets the conditions provided below to ensure reli able communications Maximum Communications Distance Baud rate Maximum network length Drop line length Total drop line length Thick Cable Thin Cable 500 kbps 100 m max 100 m max 39 m max 250 kbps 250 m max 100 m max 78 m max 125 kbps 500 m max 100 m max 156 m max Note Thick Cable 5 wire DCA2 5C10 100 m Thin Cable 5 wire DCA1 5C10 100 m Maximum 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 Terminati
