Page 5: Introduction
Models 5843HRT and 5844HRT are similar except for the method in which they are powered. Models 5843SHRT and 5844SHRT have the same features and functionality described for the Models 5843HRT and 5844HRT respectively with the exception that they have single mode optics for use with single mode fiber cable. - Page 6 Models 5843, 5844, 5843S and 5844S RS232 or TTL Optical Star Configuration: More than two Link/Repeaters connected together in a “hub and spoke” topology where the Master’s transmission is heard by all IED’s and only the Master hears the polled Slave’s response and there is no returning echo of the transmissions.
- Page 7 Models 5843, 5844, 5843S and 5844S RS232 or TTL Pin 8 Output Option Switch: (Switch 5B) Models 5843 and 5844 Links are provided with this switch to allow users who require more drive current on the TTL output pin (pin 8) to accomplish this. Selections are High or Low. Consideration should be given that the current value selected is appropriate for the input of the device being connected to this data channel.
- Page 8 Models 5843, 5844, 5843S and 5844S RS232 or TTL Number of Repeats: The Number of Repeats is the number of Link/Repeaters that may be connected in a loop configuration. The sum of Slaves in a Master/Slave loop is the number of repeats for that type of loop. The number of Peers minus one is the number of repeats in a Peer-to-Peer loop.

Page 13: 11Peripheral Equipment
Models 5843, 5844, 5843S and 5844S RS232 or TTL CAUTION Regardless of the power connection used, Model 5843HRT requires 250 mA (340 mA for the 5843SHRT) within a range of 9 to 15 VDC. An inadequate power supply not capable of supplying 250 mA over the entire operating temperature range may cause the Link/Repeater to malfunction. - Page 14 3 dB per kilometer Aging Loss: less than 3 dB Model 5843HRT and Model 5844HRT Link/Repeater optical ports are designed for ST type terminations and are compatible with multi-mode FOC ranging from 50 µm to 200 µm.

It is also possible to optically connect Link/Repeaters together which are connected to IED’s with different electrical formats. It is possible to optically interconnect Models 5845HRT and 5846HRT (operating EIA 422/485) to DYMEC Models 5843HRT and 5844HRT which are connected to IED’s operating RS-232 or TTL formats.

- Page 17 Models 5843, 5844, 5843S and 5844S RS232 or TTL WARNING When installing a Model 5844HRT or 5844SHRT Link/Repeater, an earth Ground must be attached to the Ground Stud on the side of the case before connecting to power. Failure to follow this procedure may result in electrical shock to personnel.
- Page 18 IED’s of different electrical formats (i.e., RS-232, EIA 422, EIA 485 2-wire or EIA 485 4-wire) may also be interconnected optically in the Star Configuration. Models 5845HRT and Models 5846HRT are optically compatible with the 5843HRT and 5846HRT and are used to serve to serve the EIA 422 and EIA 485 devices.

Models 5843, 5844, 5843S and 5844S RS232 or TTL 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 Point-to-Point configurations only between devices in an "optical bus"... - Page 21 Models 5843, 5844, 5843S and 5844S RS232 or TTL NOTE The communication logic and control software of the Master IED must be able to manage the receipt of its echoed request. The receipt of the echo can be used in conjunction with a watchdog timer to continuously verify loop integrity.

Page 22: Loop Operation - Peer-To-Peer Configuration
A Peer-to-Peer loop configuration is similar to the Master/Slave loop configuration except that each IED in the loop is capable of Mastering the loop in a pseudo-Master/Slave loop. To achieve this, Models 5843HRT and 5844HRT provide an electrical means of controlling the "OFF/REP" function. - Page 23 Models 5843, 5844, 5843S and 5844S RS232 or TTL NOTE The communication logic and control software of the Master IED must be able to manage the receipt of its echoed request. The receipt of the echo can be used in conjunction with a watchdog timer to continuously verify loop integrity.

Page 31: Testing And Troubleshooting
TESTING AND TROUBLESHOOTING TESTING Models 5843HRT and 5844HRT lend themselves to easy installation and testing. Testing the units requires transmitting and receiving data or setting the Test Mode switch to ON while observing that the diagnostic LEDs are illuminating in the proper sequence. - Page 32 Models 5843, 5844, 5843S and 5844S RS-232 or TTL • Determine that the IED's originating signal is within standards. NOTE If the Link/Repeater is not connected directly to an IED, determine that the electrical signal received by the Link/Repeater is not corrupt. The Link/Repeater only repeats the signal it is given, it does not re-clock or re-generate the signal.
