Universal PCI Board User’s Manual Introduction

Overview
MOXA Universal PCI (UPCI) multiport serial boards can be installed in PCI or PCI-X slots, and
support both 3.3V and 5V PCI/PCI-X. With a UPCI board, you can connect data acquisition
equipment and other serial devices to your PC over RS-232, RS-422, or RS-485. Each board has
on-chip hardware and software flow control, a built-in 128-byte Tx/Rx FIFO, and well-designed
device drivers that have been fine-tuned. This allows Moxa UPCI boards to support data
transmission speeds of up to 921.6 Kbps.
The following UPCI multiport serial boards are available from Moxa:
CP-118U-I:
8 ports, RS-232/422/485, 2KV optical isolation

Smartio—The Smart Multiport Async Solution
The Smartio Series of multiport serial boards includes the CP-168U V2, CP-104UL V2, CP-104JU
V2, POS-104UL V2, 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 V2, CP-134U-I V2, CP-132UL V2, and CP-132UL-I V2. 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.
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
