1. Introduction
USB-87Pn series is an intelligent I/O expansion unit, it features USB communication
interface, hot swap, and most of all, USB-87Pn can connects to various I/O signals in the
field by plugging in properly kind of High profile I-87K I/O modules. It is used for industrial
monitoring and controlling applications. There are more than 30 I/O modules supported with
the unit, including analog input/output, digital input/output, and counter/frequency I/O
modules.
USB-87Pn is designed with a wide power input range from +10 to 30VDC and a wide
operating temperature range from -25°C to 75°C for running in harsh and noisy environment.
It simplifies installation and maintenance of I/O modules with hot swap and auto
configuration, fault and error detection, dual watchdog, programmable Power On and Safe
values.
Various software development kits (SDK) and demos are provided, such as DLL, ActiveX,
LabVIEW driver, InduSoft driver, Linux driver and OPC Server. The I-87K series I/O modules
plugged in the USB-87Pn can be easily integrated into variant software system.

Features
Hot Swap
The USB-87Pn doesn’t need to shut down its power to replace or plug I-87K I/O modules.
Therefore, the whole system can keep operating without any interruption.
Auto-Configuration
Configurations of I-87K I/O modules can be pre configured and stored in the nonvolatile
memory of the USB-87Pn. When the USB-87Pn is power on or an I-87K I/O module is
plug in, the USB-87Pn automatically check and restore these configurations to each
I-87K I/O modules on it.
Easy Duplicate System
Using the DCON Utility Pro, you can easily make a backup of the I-87K module
configurations and write to another USB-87Pn. This design can easily and quickly
duplicate multiple USB-87Pn units with the same configuration.
Easy Maintenance and Diagnostic
The basic configurations (Auto Config, ON/OFF) are set by the DIP switch. The operator
can use only one screwdriver to set the USB-87Pn. And there are several LED status
indicators to show whether I-87K modules are configured and work properly.
If one I-87K module is damage, the user just need to get a new module of the same
model to replace the damaged one. And then check the LED indicators to know whether
the replacement is performed correctly. The design of Auto Config dip switch and slot
LED indicators are helpful for ease maintenance with no need of a PC or a laptop.

Communication
USB interface
The USB-87Pn is equipped with USB communication interface. It requires no converter,
plug and play at run time, very simple and convenient to connect with your PC.
DCON protocol
The DCON protocol for communicating with I-87K series I/O modules plugged in a
USB-87Pn is a simple command/response protocol. All commands and responses are
in easy used ASCII format.
Rugged Industrial Environment
Dual watchdog design
The I-87K series I/O modules provides module watchdog and host watchdog. The
module watchdog is a hardware watchdog; the host watchdog is a software watchdog.
The module watchdog is designed to automatically reset the microprocessor when the
module hangs. The host watchdog monitors the host controller (PC or PLC). The
output of module can go to the Safe Value state when the host fails.
Programmable power on and Safe Value
Power on value is applied when the USB-87Pn unit is powered on or reset by module
watchdog timeout, while Safe value is applied when host watchdog timeout occurs.
They are programmable for analog and digital channels to prevent unexpected outputs
when a module or a host fails.
Wide range power input (10~30 VDC)
Wide range operating temperature (-25 °C ~ +75 °C)

Fully Software Support
USB-87Pn provides free and easy-to-use configuration utility, a variety of software
development kits (including demo programs) and drivers for integrating USB-87Pn I/O
expansion units into SCADAsystems, allowing you to get started easily.
DCON Utility Pro for configurating I/O modules and monitoring real-time data
OPC Servers:
OPC is an industrial standard interface based on OLE technology. With the OPC
Server, I/O modules can be easily integrated to any software that has OPC client
capability.

EZ Data Logger
EZ Data Logger is small data logger software. It can be applied to small remote I/O
system. With its user-friendly interface, users can quickly and easily build a data
logging software without any programming skill.
Support Variant Software Development Toolkits
DLL library, ActiveX, LabVIEW toolkit, InduSoft driver, DasyLab driver and Linux driver
are included.
