  • Optional enclosure.
  • The HA5 is a RS232, RS485 to 1-Wire interface, which provides an ASCII command set for embedded controller and PC based applications that need to accommodate Dallas Semiconductor iButton and 1-Wire devices. The HA5 relieves the host of the burden of generating the time-critical 1-Wire communication waveforms while supporting all 1-Wire devices with simple ASCII commands that can be easily generated. The HA5 does all the hard work of interfacing 1-Wire networks. RS232 and RS485 versions provide as many as 26 1-Wire networks from a single host serial-port, broadcast radio or modem. The HA5 can perform Search, Conditional search and Family search functions making it easy to acquire the unique 64 bit serial numbers of all connected devices. The HA5 constantly performs a dynamic analysis of the network and adjusts the network timing to allow for variable conditions. This results in good performance with both short and long networks with many or only a few devices attached. Many sensor devices require extra power be delivered during periods of data conversions (DS1920 and DS1820 temperature sensors for example). The HA5 automatically provides the extra current these devices require with a built in smart strong-pull-up.
    Dallas Semiconductor iButtons which store data in TMEX Touch Memory File format can be read or written with simple ASCII commands. The HA5 will automatically generate and check the CRC16 error checks from Touch Memory File records.
     
    The HA5 supports analog, digital, and temperature 1-Wire devices and all Dallas Semiconductor iButtons.
