Technical OMG - USB - DIO48 Page 2 Technical Description The OMG - USB - DIO48 provides 48 channels of digital I/O configurable as inputs or outputs. Applications include PC based control and automation of sensors, switches, satellite antenna control systems, video and audio studio automation, security control systems, and othe r industrial automat[...]

Technical OMG - USB - DIO48 Page 3 Electrical Characteristics Figure 1, below provides the electrical characteristics of each Input/Output. Each port is buffered with a 74ABT245 octal bi - directional transceiver. Each input is capable of sinking up to 64 mA, while each output can source up to 32 mA. The OMG - USB - DIO48 requires a 5V power source[...]

Technical OMG - USB - DIO48 Page 4 Pull Ups Ten pin bussed resistor packs are installed to provide pull - ups to the input ports. These are installed on all ports. The pull - up resistor packs are rated at 10K ohms. Figure 2 below provides the bussed resistor and corresponding port. The resistors insure that no line is floating which is not connect[...]

Technical OMG - USB - DIO48 Page 5 Banks and Ports The OMG - USB - DIO48 has two 50 pin headers. Each 50 pin header is a bank of three ports, comprising a total of six eight bit ports. Each port is eight bits wide and may be configured as an input or output po rt. Figure 3 below gives the bank and port organization. Bank 1 – P2 Bank 2 – P3 Port[...]
