TERM DEFINITIONS, COMMENTS, PROPOSALS, GUIDANCE & SUGGESTIONS RS232 = 3-Wire(20Kbps@50ft.), RS485 = 2-Wire(100Kbps@4000ft.), RS422 = 4-Wire(100Kbps@4000ft.), Half-Duplex (RS485) Allows Data Flow in one Direction at a Time, Full-Duplex (RS232, RS422) Allows Data Flow in Both Directions Simultaneously and Avoids "DATA COLLISIONS;" However, 3-4 Wires are Required, and TX and RX Signals must be Properly Aligned (TX=>RX and RX<=TX and DIFFERENTIAL SIGNALS must be "PHASED" Correctly or Data will be Inverted). RS485 only requires 2-Wires and must be "PHASED" and Generally is Preferred for it's Simplicity in many Systems. By "CASCADING" Repeaters and/or Multi-Repeaters very "LARGE & ROBUST" Networks can be formed (Thousands of Nodes) without violating any RS485 Specifications, and further provides proper Termination and Bias throughout the Network. Galvanic Isolation helps prevent Network "melt-down" and also Reduces and/or Eliminates Noise and Ground Potential (Common Mode Limits) issues. Networks with "Home Runs" and/or "Daisy Chains" can be accommodated for maximum Flexibility and Extended Distance operation. Let us spin a very large RS485 network for you. Fiber optics can also be Integrated into these System and provide additional Noise Immunity and other benefits. "FUNNEL" Repeaters work very well in Single Master Systems, and "TRUE" Repeaters will work for Multi-Master Systems, as well. Many Accessories are Available, and we can Conformal Coat units. Almost of our units are Automatic, and will operate at 115.2Kbps minimum, with no speed or COMM-Specification settings required. Relative Humidity spec. is 10% to 90% Non-Condensing.
