EST3 Network Communications Network and Audio Data Upgrades

Communication Methods Standard Copper Cable, RS485 Card Fiber Optic Interface Multimode Single Mode, High and Low Output Telco Copper Lines, Short Haul Modem

Common Communication Features Style 4 or 7 (Class ‘B’ or ‘A’) Can switch media on the same network There are rules

3-RS485x Communication Card #18 AWG Copper, up to 5000’ over 3 Nodes Network Data, 90Ω, .3 µf Audio Data, 90Ω, .09 µf Use 3-RS485B for… Class ‘B’ Network Data Class ‘A’ Network Data Class ‘B” Audio Data Use 3-RS485A for… above plus Class ‘A’ Audio Data

3-FIBMB2 Fiber Optic Interface Network Data & Audio on the same board Multimode & Single Mode Fiber both Lo and High output Mix Fiber [TYPES] and RS485 Copper Communications

3-FIBMB2 Fiber Optic Interface SMXLO2 Single Mode Transceiver Approx. 8.7 miles, 16 dBm budget SMXHI2 Single Mode Transceiver Approx. 24.85 miles, 29 dBm budget MMXVR Multimode Transceiver Approx 7000 feet, 10 dBm budget

Transitions Copper to Fiber Any Fiber to Any Fiber NO Fiber transition to Short Haul at the same node, need copper between NO Fiber or Short Haul at an Annunciator, copper only *Retrofit or upgrades to existing EST3 single mode systems require specific considerations. When an existing single mode driver (SMXLO or SMXHI) must be replaced with a new SMXLO2 or SMXHI2, the 3-FIBMBs must also be updated with the newer 3-FIBMB2 for compatibility. The 3-FIBMB is not compatible with 3-FIBMB2 when using single mode driver modules (SMXLO, SMXLO2, SMXHI or SMXHI2), for service replacement and network expansion applications all or some of the 3-FIBMBs may need to be updated to 3-FIBMB2. By using the 24Vdc input on the 3-FIBMB2 it may be possible to minimize the number of 3-FIBMBs that need to be upgraded.

Fiber Benefits & Applications Immune to electrical noise Use through hazardous atmospheres High level of security Resist effects of moisture Eliminates ground faults

Cost Considerations Driving Factor = Distance Multimode Higher cost fiber, lower cost electronics ST Connectors (physical connector) Single Mode Lower cost fiber, higher cost electronics SC Connectors (physical connector) Driving Factor = Distance Performance is Equal but for distance

3-FIBMB2 Fiber Optic Interface Transceivers SMXLO2 SMXHI2 MMXVR 24 VDC input for communications during servicing or updating 3-FIBMB to 3-FIBMB2 installations

Short Haul Modem 3-NSHMx Up to 6 miles between nodes Uses 2 Pair existing copper telco lines (must have continuity) Integrated test modes Accessories transient suppression & ground fault Media Switch Conditions: Standard copper to Short Haul Short Haul to standard copper Short Haul to Short Haul 3-NSHM1 & 3-NSHM2

Copper / Short Haul / Copper Transient Suppression Copper Short Haul Copper Short Haul

How the Short Hauls fit in? Interface Card plugs into RS485 Slot on CPU Ribbon cable to NSHMx NSHMx to Chassis

3-NSHMx Ground Fault Detection GFD Short Haul modem wiring is opto isolated GFD module monitors ground fault on isolated wires Requires 24 VDC & SIGA-CT1 to monitor 2 Pair GFD G PS SIGA-CT1

Short Haul Design Considerations Network Data Only – No Audio Cannot use at Annunciators Requires two pairs, runs full duplex Cannot have Short Haul and Fiber at the same node
