Chapter 2

UnpackingAs with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply
touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.

Installing the software
Refer to the MCC DAQ Quick Start and the USB-PDISO8/40 product page on our website for information
about the software supported by the USB-PDISO8/40.
Install the software before you install your device
The driver needed to run the USB-PDISO8/40 is installed with the software. Therefore, you need to install thesoftware package you plan to use before you install the hardware.

Connecting the external power supply
Power to the USB-PDISO8/40 is provided with the +9 V external power supply (CB-PWR-9). You must
connect the external power supply before connecting the USB cable to the USB-PDISO8/40 and your computer.
If you are connecting more than one MCC USB device, make sure that you provide adequate power to eachdevice. Refer to Power limitations using multiple USB-PDISO8/40 devices on page 13.
To connect the power supply to your USB-PDISO8/40, connect the external power cord to the power connector
labeled POWER IN on the USB-PDISO8/40 enclosure (PWR IN on the board). Refer to Figure 2 on page 8 forthe location of this connector.
The green PWR LED lights when +9 V power is supplied to the USB-PDISO8/40. If the voltage supply is lessthan +6.5 V or more than +12.5 V, the PWR LED does not light.
Do not connect external power to the POWER OUT connector
The power connector labeled POWER OUT on the enclosure (PWR OUT on the board) is used to provide power
to an additional MCC USB device. If you connect the external power supply to the POWER OUT connector, theUSB-PDISO8/40 does not receive power, and the PWR LED does not light.

Installing the hardware
Connect the USB-PDISO8/40 using the cable provided to a USB port on a computer running Windows.
Windows finds and installs the device driver automatically, and notifies you that the device is ready to use.
The USB LED turns on after the device is successfully installed.
You can connect up to four compatible MCC USB products in a daisy-chain configuration to a USB port onyour computer.
If the USB LED turns off
If communication is lost between the device and the computer, the USB LED turns off. To restore

USB-PDISO8/40 User's Guide

Functional Details

POWER IN connector
The USB-PDISO8/40 requires between 6.5 V and 12.5 V of external power. An external power connection isrequired to activate the relays and to run tests in InstaCal.
To supply external power, connect the POWER IN connector to the supplied +9 V external power supply(CB-PWR-9).
The USB specification allows high-power devices to draw up to 725 mA. When all eight relays are energized,
the combined current draw exceeds the maximum allowed for high-power USB devices. Therefore, external
power is required.

POWER OUT connector
Use the POWER OUT connector to provide power to additional daisy chained MCC USB devices from a single
external power supply. A user-supplied custom cable is required to daisy chain multiple devices.

USB LED
The USB LED indicates the communication status of the USB-PDISO8/40. This LED uses up to 5 mA ofcurrent and cannot be disabled. The following table explains the function of the USB LED.

Daisy chaining additional devices to the USB-PDISO8/40
Daisy-chained USB-PDISO8/40 devices connect to the USB bus through the high-speed hub on the USBPDISO8/40. You can daisy chain up to four MCC USB devices that support daisy-chain configurations to asingle USB 2.0 port or USB 1.1 port on your computer.
Use the supplied cable or an equivalent full-speed cable when daisy chaining to other MCC USB devices.
The device already connected to the computer is referred to as the host device.
The additional device(s) that you want to daisy chain to the host USB-PDISO8/40 is referred to as the slave
device.

This procedure assumes you already have a host device connected to a computer and to an external powersource.
To daisy chain MCC USB devices, complete the following steps below.
1.

Connect the POWER OUT connector on the host device to the POWER IN connector on the slave device.
This step is required only if you plan to daisy chain power to another device.

2.

Connect the USB OUT connector on the host device to the USB IN connector on the slave device.

3.

To add another device, repeat steps 1-2 by connecting the slave device to another slave device.

A daisy chain example is shown in Figure 10. Note that the last board in the chain is supplied with external
power.

Figure 10. USB-PDISO8/40 daisy-chain connections (configuration not near full power load)

Power limitations using multiple USB-PDISO8/40 devices
When daisy chaining additional MCC USB products to the USB-PDISO8/40, make sure that you provide
adequate power to each device that you connect. The USB-PDISO8/40 is powered with a 9 VDC nominal,
1.67 A external power supply.
When connecting multiple devices, power supplies with higher current capability – such as the CB PWR-9V3A– are available from MCC.

Supply current
Running one USB-PDISO8/40 with all relays on draws 820 mA from the 1.67 A supply. When using theUSB-PDISO8/40 under full load conditions, you cannot daisy chain additional MCC USB products unless you
supply external power to each device 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 product that you connect.

13

USB-PDISO8/40 User's Guide

Functional Details

Voltage drop
A drop in voltage occurs with each device connected in a daisy chain system. The voltage drop between thedevice power supply input and the daisy chain output is 0.5 V maximum. Factor in this voltage drop when you
configure a daisy chain system to ensure that at least 6.5 VDC is provided to the last device in the chain.
Always provide a separate power supply when the USB-PDISO8/40 is the last device in the chain.

Relay contact protection circuit for inductive loads
When you connect an inductive load to a relay, energy stored in the inductive load can induce a large voltage
surge when you switch the relay. This voltage can severely damage the relay contacts. To limit the voltage
surge across the inductive load in a DC circuit, install a kickback diode across the inductive load. Refer to thecontact protection circuit in Figure 11. For AC loads, install a metal oxide varistor (MOV).
