Max485 for RS485 Communication How to use MAX485 Modules These two modules are great for connecting remote distance parts to your project. Using the Max485 modules and a length of twisted pair wire, you can send data back and forth from remotely located components without the EMF interference that you would normally get with normal cabling. A great way to connect Security related components in your DIY systems. How do they work Adopting half-duplex communication to implement the function of converting TTL level into RS-485 level, it can achieve a maximum transmission rate of 2.5 Mbps. MAX485 transceiver draws supply current of between 120uA and 500uA under the unloaded or fully loaded conditions when the driver is disabled. The driver is limited for short-circuit current and the driver outputs can be placed at a high impedance state through the thermal shutdown circuit. As most applications require at least (1) transmit and (1) receive unit, we have included two MAX485 Modules in this package. Package contains(2) MAX485 Modules
