There is now a number of cable replacements solutions available including Bluetooth. So instead of running a cable from one end of the factory to the other, from one room to the commercial kitchen printer which needs installed, maintained, cleaned. Are you considering using a cable replacement solution? or do you keep doing what you have always been doing and installing cables from habit?
For RS232 cables for industrial use including CNC machines LM058 is available http://www.lm-technologies.com/business/bluetooth-adapters/LM058/rs232-cable-replacement---external-antenna
For EPOS / POS cable replacement to your kitchen printer the LM048SPA is available http://www.lm-technologies.com/business/bluetooth-adapters/LM048SPA/rs232-serial-printer-adapter
Are you considering moving from cables to a cable replacement solution?
