Model CH45 EIA 422 or 485 1. INTRODUCTION The DYMEC-DynaStar Model CH45 is a data communication Link/Repeater Card, for use in the DYMEC-DynaStar 3900 Series Chassis, which allows the replacement of copper wire with fiber optic cable. Link/Repeaters simply convert electrical signals to light for transmission, then, when received, convert the light to electrical signals. This is done for EIA 422 and EIA 485 formats. Link/Repeaters are passive to software protocol. They are not ad

Model CH45 EIA 422 or 485 Slave: A Slave is an IED that is passive in a Master/Slave configuration. A Slave's communication is under the control of the Master, and the slave only responds to specific poll requests from the Master. Peer: Peers are IEDs that have equal status and each may initiate a communication when allowed by the system software by a time slot, token, etc. FOC: Fiber Optic Cable. Single-mode: Single-mode fibers generally have diameters of 5µm to 13µm. B

Model CH45 EIA 422 or 485 NOTE The diagnostic LEDs only illuminate when there is signal traffic and are not illuminated during signal "quiet" times. If during quiet time, TE and TO are illuminated, it suggests either a polarity reversal (pin 2 with pin 1) or that the IED is biased pulling the “A” (+) line with respect to the “B” (-) line. After checking the polarity on the connections, refer to Section 3.5. The diagnostic LEDs may "flicker" when data is passing. This is normal ope

Model CH45 EIA 422 or 485 The DYMEC-DynaStar Optical Stars can also be used to create a multi-drop Master / Slave Optical Star network. The Model CH45 is optically compatible with the OS5 and OS9 Master and Slave ports. Figure 11 shows a typical connection of an Optical Star network. The master IED must always be connected to the Master port (port 1) of the Optical Star. The slave IED’s must always be connected to the Slave ports (port 2 and up) of the Optical Star.

Model CH45 EIA 422 or 485 2.2 LOOP OPERATION - MASTER/SLAVE CONFIGURATION NOTE Before constructing a loop network, be sure that the software protocol of the Master is capable of managing the receipt of its own echoed transmission. If it cannot, then use either an Optical Bus or Optical Star configuration. This configuration supports a system which requires more than two IEDs to be communicating. In a Master/Slave loop system, one IED acts as a Master at all times and addresse

Models CH45 EIA 422 or 485 The Master must have its Mode Jumpers in the "OFF" position. When it transmits a request out its T optical port, it will receive the echo of its request at its R optical port. This request has gone around the loop, and has been repeated by each Slave in the loop. However, the Master does not repeat (re- transmit) any of these received signals optically back around the loop, because its Mode Jumpers are in the "OFF" position. NOTE The communication logic
