Serial Converter
USB-COMi
The USB-COMi is a USB to RS485 serial converter. It allows easy serial port expansion without requiring IRQ, DMA, or I/O port resources. The converter allows the user to easily and economically connect RS485 devices to a host using USB. The RS485 communications standard is used by DGH sensor based data acquisition modules and many industrial control devices.

Analog Output Modules
D3000/4000
The DGH D3000/4000 series are complete computer-to analog output modules. They communicate, in ASCII, with RS-232 and RS-485 serial ports. Simple ASCII commands are used to control a 12-bit DAC (Digital-to-Analog Converter) which is scaled to commonly used current and voltage ranges.

Analog Input Modules
The modules provide direct connection to a wide variety of sensors and annunciators. They perform all signal conditioning and linearization and contain no pots or DIP switches. All user-selectable settings, such as ranges are stored in nonvolatile EEPROM, which maintains these values even after power is removed.
