Introduction and Installation OMG - USB - DIO48 Page 1 Introduction Overview The OMG - USB - DIO48 provides six eight - bit ports that may be individually configured as inputs or outputs. What’s Included The OMG - USB - DIO48 is ship ped with the following items.
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 automati.
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.
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.
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.
Technical OMG - USB - DIO48 Page 6 50 pin ribbon cable pin out Each of the two 50 pin ribbon cable headers has the following pin out as shown in Figure 4.
Programming OMG - USB - DIO48 Page 7 Programming Application Programmers Interface (API) The SeaIO driver, API, and utilities have been included to provide control over the hardware in Windows environments. The following section is designed to help the customer understand the API connection to the actual I/O for the OMG - USB - DIO48.
Programming OMG - USB - DIO48 Page 8 Port Configuration: Each eight - bit port can be configured as inputs or outputs . The API provides a set adapter state call to access the control words. N ote: The control panel also allows you to configure the device.
Programming OMG - USB - DIO48 Page 9 Relative Addressing vs. Absolute Addressing The SeaIO API makes a distinction between “absolute” and “ relative” addressing modes. In absolute addressing mode, the Port argument to the API function acts as a simple byte offset from the base I/O address of the device.
Programming OMG - USB - DIO48 Page 10 Figure 7 below gives t he absolute address for each bit on this device. Bank 1 – P2 Bank 2 – P3 Addres s Port - Bit Addres s Port - Bit 0 A1 - 0 24 A2 - 0 1 A.
