Welcome to the Senquip Q4 2024 newsletter. Wishing you a great break over christmas and look forward to working with you again in 2025. 🎄

After yesterdays post on the differences between RS232 and RS485, we have been asked a few times why RS485 is more noise immune. It is because RS485 uses a differential signalling method. Here's how it works, and why it's effective: 🔗 Differential Signalling in RS485: RS485 uses two wires to carry a pair of signals that are exact opposites (one is the inverse of the other). The receiving device compares the difference between the two signals to interpret the data. Since external noise usually affects both wires equally (common-mode noise), the difference between the signals remains unchanged, effectively cancelling out the noise. This is the reason that twisted-pair cables are often used in RS485 – the twisting ensures that both wires are exposed to the same noise levels, enhancing noise rejection. ⛓️💥 Why RS232 is More Susceptible to Noise: RS232 uses single-ended signalling, where data is sent over a single wire relative to a ground reference. Any noise affecting the signal line or the ground reference directly impacts the signal, making it harder to filter out. Saying RS485 is the winner is a bit disingenuous. As mentioned in the previous post, each has its advantages: choose RS232 if you need a simple, low-cost solution for point-to-point communication over short distances and use for RS485 when building a robust, long-distance network involving multiple devices, especially in noisy industrial settings. #senquip #remotemonitoring #remotecontrol #rs485 #rs232

RS232 and RS485 are standards for serial interfaces that each specify the transmission media and a defined set of logic levels, data rates and timings. These are some of the oldest serial interfaces around, yet they are still very widely used in control and measurement equipment, mainly due to their simplicity and low cost. RS232: The Simplicity Specialist 🟢 Very widely used, especially on older equipment 🟢 Full duplex communications (simultaneous transmit and receive ) 🔴 Only supports communication between two devices 🔴 Only works over short distances of about 15m 🔴 Relatively susceptible to electrical noise RS485: The Networking Powerhouse 🟢 Supports several devices on the same bus (multi-drop) 🟢 Differential signals offer high electrical noise immunity 🟢 Works over longer distances of up to 1200m 🟢 Supports faster transfer speeds than RS232 🟠 Requires termination resistors 🔴 Half-duplex communications (transmit or receive, not simultaneously) Choose RS232 if you need a simple, low-cost solution for point-to-point communication over short distances, such as connecting to a nearby sensor. Opt for RS485 when building a robust, long-distance network involving multiple devices, especially in industrial settings. Senquip devices support both RS232 and RS485 interfaces, allowing you to make the right choice for your specific application. #senquip #remotemonitoring #remotecontrol #rs485 #rs232

This week started with yet more insolvencies in the Low Power Wide Area Network (LPWAN) space. #NNNCo, Australia’s #LoRaWAN network operator entered voluntary liquidation on 15th November, and #SimpleCell, the #Sigfox operator in the Czech Republic shut down. This follows dozens of other LoraWAN and Sigfox closures over the past 24 months. Interestingly, AT&T followed NT Docomo in announcing the end of support for NB-IoT. This is hardly surprising; to survive as an operator selling minute amounts of data at very low cost, requires millions of subscribers. There just aren’t that many golden opportunities. With the cost of 4G and 5G LTE modems continuing to fall, and satellite direct to cell services launching from SpaceX and others in 2025, why would you continue to fund a proprietary terrestrial network. Through good fortune or foresight, #Senquip has invested in 4G, 5G and satellite direct to cell technologies. This places us well to provide telemetry devices that support global coverage, even where there is no terrestrial infrastructure. #senquip #iiot #remotemonitoring #remotecontrol

Senquip devices can power external sensors even when input power is disconnected. The QUAD can generate an output voltage from 5V to 25V, and the ORB 12V; both from the internal 3.7V backup battery. We are often asked how this is possible. Senquip uses a boost converter, also called a step-up converter, that converts a low DC voltage to a higher DC voltage. Think of it as a DC transformer. By storing energy in an inductor during a "switch-on" phase and then releasing that energy through a diode to a capacitor during the “switch-off” phase, we can boost the voltage by adding the inductor voltage to the input voltage. If you would like to know more about boost converters, Wikipedia has a great introduction. #senquip #iiot
