1. To insure redundancy ControlNet also expects the two identical packets to be delivered at approximately the same time Since longer fiber equals a longer delay time all fiber segments for A and B channels must be approximately the same length As it s difficult to route two separate paths of equal length ControlNet allows for a skew in the propagation delay or delivery time of packets between channels A and B ControlNet specifies this to be no greater than 1 6us channel A to channel B Dual Redundant Self healing Ring CHANNEL A pool CHANNEL Dk CHANNEL B om Figure 4 3 Example 2 Dual Channel Maximum Delay A skew of only 1 6us does not seem like much but when divided by the standard delay time of 5 01ns meter for typical optical fiber this allows for roughly 319 36 meters or 1047 77 feet A good rule of thumb to remember would be 300 meters of 1000 feet This is in excess of the length of 3 football fields 36 EOTec 2000 ControlNet Ring Communications Manual Planning and Installation The total network delay time for channel A can easily be calculated by adding up all the delays found in Example 1 Now a total for channel B must be calculated As you can see in Table 4 12 and Table 4 13 the delay in channel B is longer than channel A If you remember what was learned from example 1 when determining the total network delay time for a ring it is not necessary to include all of the fiber segments The maximum

3. There are two relays K1 Fiber 1 and K2 Fiber 2 to provide contacts to a remote alarm There are also two 3 pin headers J1 Fiber 1 and J2 Fiber 2 to set the option to close or open the relay on alarm see Figure 2 13 If the jumpers are set between the center post and the post marked NO the relays will open on an alarm condition If the jumpers are set between the center post and the post marked NC the relays will close on an alarm condition Figure 2 12 ControlNet Board Module Reassembly Once the alarm jumpers are set the three PCBs can now be reassembled by reconnecting the top and bottom PCBs into the center PCB at the 2 x 15 pin header mounted at the back of all three PCBs Shown in Figure 2 7 Reinsert the PCBs back into the housing by first locating the DIN rail tabs inside the housing and aligning them toward the top as shown Figure 2 14 This is now the proper top to bottom orientation used to reinsert the PCBs Insert the PCB assembly by aligning each board with the proper housing guide shown in Figure 2 15 Each board must be lined up on its own guide and slide easily into the housing If these boards do not line up properly they can be adjusted by pushing pulling the connections of the 2 x 15 connector located at the back of each board See Figure 2 7 When everything is aligned correctly the PCB assembly will easily slip back into the housing and latch in place If it is not easily reinstalled do not force t

6. Attenuation Before selecting the proper transceiver to use in your application you must first calculate the power budget for the fiber cable lengths in your plan If you install longer distance fiber cables install bulkhead connectors or fusion splices expose the cable to multiple sharp bends or employ different quality cable or connector types you must recalculate your attenuation levels Use the example below to help you understand how to determine fiber attenuation levels of your fiber cables From Table 4 3 above you can see the maximum optical dynamic range or power budget for a 2C32 LC MM MM Module is 11dB using 62 5 125um fiber This means that the maximum amount of attenuation of light between this module and the one connected at the other end of the fiber cannot exceed 11dB This power budget is valid throughout the operating temperature range 0 to 60 C If you modify the cables with splices or connectors then you must recalculate the attenuation levels Use the steps in Table 4 4 to determine the correct fiber attenuation for selecting the correct EOTec self healing ring modules for your application Step Description Explanation 1 Determine total power budget Given the application the size of the network and fiber type how much total loss dB is expected and allowed 2 Determine insertion loss Add Account for all added attenuation from insertion loss up the loss from connectors on the fiber segments

23. Understanding Propagation Delay The ControlNet Maximum Propagation Delay specification refers to the worst case signal delay between any two nodes on a network You will need to figure out the worst case scenario based on media distances and the number of EOTec modules that the data signals will pass through You should be aware that this does not mean all media and EOTec modules in your network only the media and modules that link the two furthest nodes of your system Network delays include the delays through coax and fiber media and the EOTec Self Healing Ring modules you are planning to use Use Example 1 and Example 2 to help you understand which media and Ultra modules to use when calculating maximum propagation delay In order for a network to operate the sum of the network s delays must be equal to or less than the ControlNet specified maximum propagation delay of 121ys The total network allowable bi directional delay is 121us The propagation delays through taps are minimal and can be ignored Listed in Table 4 5 are delay values for EOTec ControlNet devices and media Media Item Propagation Delay Time 2C31 1 4us module 2C32 1 4us module RG 6 Coax Cable 4 17us km or 1 27us 1000 ft Multi mode Fiber 5 01us km or 1 53us 1000 ft Single Mode Fiber 5 01us km or 1 53us 1000 ft Table 4 5 Network Propagation Delay 32 EOTec 2000 ControlNet Ring Communications Manual Planning and Installation Exam
