Chapter 1
Introducing the USB-DIO96H/50
Overview: USB-DIO96H/50 features
This user's guide contains all of the information you need to connect the USB-DIO96H/50 to your computer and
to the signals you want to measure or control.
The USB-DIO96H/50 is supported under popular Microsoft®Windows®operating systems. The USB-
DIO96H/50 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-DIO96H/50 provides 96 digital I/O lines, high output current, and one 32-bit external event counter.
The USB-DIO96H/50 is powered by an external +9 V unregulated power supply that is shipped with the
module. A USB cable is also included.
Power OUT and USB OUT connectors let you power and control multiple modules from one external power
source and one USB port in a daisy chain fashion. Depending on your load requirement, daisy chained boards
may require more than one separate power supply.
The 96 digital I/O lines are accessed through two 50-pin connectors. Each digital port group is divided into two
8-bit ports and two 4-bit ports, and is a discrete emulation of 82C55 mode zero operation. You can configure
each port independently for either input or output.
The USB-DIO96H/50 outputs are high-drive TTL that can source 24 mA and sink 64 mA. Additional buffering
is typically not required to drive external devices.
Each digital port has an associated pull-up resistor to drive the ports high during power up and reset. You can
optionally configure this resistor for a pull-down configuration. All I/O bits are set to input mode on power up
and reset.
The USB-DIO96H/50 is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench
(see Figure 1-1).

USB-DIO96H/50 User's Guide Introducing the USB-DIO96H/50
Connecting a USB-DIO96H/50 to your computer is easy
Installing a data acquisition device has never been easier.
!The USB-DIO96H/50 relies upon the Microsoft Human Interface Device (HID) class drivers. The HID
class drivers ship with every copy of Windows that is designed to work with USB ports. We use the
Microsoft HID because it is a standard, and its performance delivers full control and maximizes data
transfer rates for your USB-DIO96H/50. No third-party device driver is required.
!The USB-DIO96H/50 is plug-and-play. There are no jumpers to position, dual in-line package (DIP)
switches to set, or interrupts to configure.
!You can connect the USB-DIO96H/50 before or after you install the software, and without powering down
your computer first.
When you connect an HID to your system, your computer automatically detects it and configures the
necessary software. You can connect and power multiple HID peripherals to your system using a USB hub.
!You can connect your system to various devices using a standard four-wire cable. The USB connector
improves upon serial and parallel port connectors with one standardized plug-and-port combination.
!Data can flow two ways between a computer and peripheral over USB connections.
Make sure that you have the latest Windows Updates installed for your USB driver, particularly "XP Hotfix
KB822603."

Power limitations using multiple USB-DIO96H/50 modules
When daisy chaining additional MCC USB Series products to the USB-DIO96H/50, you must ensure that you
provide adequate power to each module that you connect. The USB-DIO96H/50 is supplied with a 9 VDC
nominal, 3.0 A external power supply.
Supply current
Running one USB-DIO96H/50 at full load draws 2.6 A from the 3A supply. When using the USB-DIO96H/50
under full load conditions, you cannot daisy chain additional MCC USB Series products unless you supply
external power to each module in the chain.
If you are not sure how much current your application requires, we recommend that you provide separate power
to each MCC USB Series product that you connect.
Voltage drop
A drop in voltage occurs within each module connected in a daisy chain system. The voltage drop between the
power input of each MCC USB Series products and its power output is 0.5 V maximum. Factor in this voltage
drop when you configure a daisy chain system to ensure that adequate power is provided to the last modules in
the chain. A daisy chain system in a full-power-load configuration is shown in .Figure 3-3

The daisy chain power output allows multiple MCC USB Series boards with a USB hub output
port to be powered from a single external power source in a daisy chain fashion.
The voltage drop between the input of one module and its daisy chain output is 0.5 V maximum.
You should plan for this voltage drop when configuring a daisy chain system to assure
functionality of the last board in the chain.

There is a total of 24 I/O per bank (PORTA, PORTB, PORTCH, PORTCL). These specifications
are for a power supply input voltage of 9 volts. Higher input voltages will increase the power
dissipation and will further reduce the total current available from each port.
