Connect Tech Blue Heat/Net User Manual Serial Line Interface Tutorial RS-232 Line Interface: RS-232 is the simplest, least expensive line interface standard. It is also referred to as EIA232 and TIA/EIA-232. The RS-232 specification signals levels of +3V to +15V for a logic 0 or Space, and -3V to -15V for a logic 1 or Mark. The Blue Heat/Net has RS-232 signal levels with a typical range of +/- 8 Volts.
Connect Tech Blue Heat/Net User Manual Any noise injected into the wires is cancelled at the receiver, leaving only the original, undistorted data signal. Twisted pair cables are always used in RS-485, this ensures that the communications are robust and as error free as possible. RS-485 signal levels are between 0 and 5 Volts, the differential voltage can be as little as 200mV.
Connect Tech Blue Heat/Net User Manual Multi-drop 4-wire, full duplex RS-485 communications: In a multi-drop 4-wire RS-485 network, 2 to 32 devices are connected together. Note that each RS-485 receiver counts as a device or “load”. In this multi-drop mode of communication, a master slave protocol must be enforced, that is, all communication is initiated by the master, in this case a Blue Heat/Net.
Connect Tech Blue Heat/Net User Manual Bus contention on RS-485 multi-drop networks: Bus contention occurs when two or more devices enabled on a bus attempt to run the bus to opposite logic values. From the diagram above, we can see that there are multiple RS-485 transmitters (TXD) on the bus. To avoid the bus contention problem, the RS-485 transmitter features a tri-state, or high impedance mode controlled by an input pin (enable).
Connect Tech Blue Heat/Net User Manual Bias and Termination Resistors in RS-485 networks: Termination Resistors in RS-485 networks: RS-485 networks often benefit from the installation of termination resistors. Termination is rarely required for lower baud rates, for example 9600 baud or less. However, RS-485 networks are transmission lines, and can suffer from the electrical effects of ringing, or undershoot and overshoot, all of which can cause data errors, especially at higher baud rates, like 115.
Connect Tech Blue Heat/Net User Manual Bias Resistors in RS-485 networks: In multi-drop RS-485 networks, the transmitters are always placed in the high impedance mode when there is no transmit activity. In this mode, the voltage at the RS-485 receivers tends to float to 0 Volts which will not maintain a stable value. In addition, the high impedance of RS-485 receivers makes them susceptible to electrical noise.
