Up to 32 receivers can be driven by any one RS-485 driver, allowing you to put together large systems with many drop points.If you are using termination resistors, they should be located at opposite ends of the system.
Features
- power versatility, making it perfect for field testing solutions. It converts unbalanced RS-232 signals to balanced RS-422 or RS485 signals. RS-485 is an enhanced version of the RS-422 standard, allowing multiple drivers and receivers on a two-wire system. Power
The 485BAT3 can be powered in three ways: batteries, port powered, or power supply. Use the battery power option when you have a low power RS-232 port (found on many laptops today) or no handshake lines or when it is inconvenient to use a power supply. Install 2 AAA batteries (not included) and put the Battery On/Off switch in the ON position. The 485BAT3 will draw as much power as possible from the RS-232 port and get any additional current necessary from the batteries. If you have a full power port and all your handshake lines,.
