Smartio—The Smart Multiport Async Solution

The Smartio Series of multiport serial boards includes the CP-168U, CP-104UL, CP-104JU, POS-104UL,

CP-102UL, and CP-102U. These boards provide RS-232 serial ports for connecting terminals, modems, printers,

scanners, cash registers, bar code readers, keypads, numeric displays, electrical scales, data acquisition

equipment, and many other serial devices to a PC. These boards are a reliable, high-performance solution for

multiport serial communication.

Industio—The Industrial Multiport Async Solution

The Industio Series of multiport serial boards includes the CP-118U-I, CP-118U, CP-138U-I, CP-138U,

CP-114UL, CP134U, CP-134U-I, CP-132UL, and CP-132UL-I. These boards are designed for industrial use, with

serial ports that can be configured independently for RS-232, RS-422, or RS-485 operation. Industio boards

provide a reliable communication link over distances of up to 4000 ft and support point-to-point full-duplex or

multi-drop half-duplex. With RS-485 operation, a single port can connect to 32 devices in a multi-drop

environment.

ADDC

(Automatic Data Direction Control) for RS-485

ADDC™ (Automatic Data Direction Control) makes it easier to manage 2-wire RS-485 half-duplex connections,

eliminating the need for software interference. This means that it is not necessary to write extra code for

Windows applications to control the half-duplex protocol. ADDC intelligence is built into Industio boards.

Serial-over-fiber Board

The CP-102UF is a serial-over-fiber board designed for industrial automation applications that require a long

distance, multi-point, PC-based data acquisition solution. The single-mode model (CP-102UF-S) can transmit

up to 40 km, and the multi-mode model (CP-102UF-M) can transmit up to 5 km. For many industrial

applications, an even bigger benefit is that optical fiber isolates the data from dangerous increases in ground

potential, ground loops, and electrical EMI/RFI electromagnetic radiation.

Built-in Termination Resistors for RS-422 and RS-485

Industio boards have termination resistors built-in, eliminating the headaches involved in determining the

proper impedance for the resistors. For additional information, please refer to Chapter 2.

ESD and Isolation Protection

Certain models include TVSS (Transient Voltage Surge Suppressor) technology to help prevent damage due to

lightning or high potential voltage. Optical isolation (2000V) and embedded protection (max. ESD of 16 KV,

max. EFT of 2 KV) are also available with certain models. These features help provide protection in critical or

harsh factory-type environments.

PCI Solution

UPCI boards comply with PCI Spec. 2.1 and do not require switches or jumpers. IRQ and I/O address is

automatically assigned by the PCI BIOS. This means that the board must be physically installed in the computer

first before the driver software is installed.
