1 Introduction
This chapter introduces the HP Peripheral Components Interconnect Multiplexer (PCI MUX)
product. It also describes the components of HP AD278A/AD279A PCI MUX.
This chapter addresses the following topics:
•“AD278A/AD279A PCI Multiplexer Components” (page 9)
•“AD278A/AD279A PCI MUX Adapters” (page 9)
•“Port Modules” (page 11)
•“Fan-Out Cable for AD278A PCI MUX 8-Port Adapter” (page 12)
Overview
HP AD278A/AD279A PCI MUX is a high-speed serial communication multiple port product. It
combines various signals for transmission over a single channel, and provides intelligent
communication functions to off-load CPU serial communication processing tasks. The multiple
ports connect different peripheral devices for communication.
AD278A/AD279A PCI Multiplexer Components
Table 1-1 to Table 1-4 list components of HP AD278A/AD279A PCI MUX product and their part
numbers. All the components are Restriction of Hazardous Substance (RoHS) compliant.

Every AD278A/AD279A PCI MUX adapter card has processors that control the flow of data
through multiple communication ports.
AD278A PCI MUX 8-Port Adapter
The AD278A PCI MUX 8-port adapter can control the operations of up to eight high speed serial
ports. It works on both 3.3 V and 5 V systems. For more information, see “Card Specifications”
(page 29). The AD278A PCI MUX 8-port adapter supports a fan out cable as an interface.
Figure 1-1 shows AD278A PCI MUX 8-port adapter.
Figure 1-1 AD278A PCI MUX 8-Port Adapter
AD279A PCI MUX 64-Port Adapter
The AD279A PCI MUX 64-port adapter can control the operations of up to 64 high speed serial
ports. It works on both 3.3 V and 5 V systems. For more information, see “Card Specifications”
(page 29). The AD279A PCI MUX 64-port adapter supports 16 to 64 ports by using up to four
external port modules, to be ordered separately.

10 Introduction

Port Modules
A port module is an interface between the AD279A PCI MUX 64-port adapter and the RS-232
peripheral device. Table 1-6 lists the port modules that can be connected to the AD279A PCI
MUX 64-port adapter.
Table 1-6 Port Modules
Number of PortsInterfaceDescriptionProduct Number
16RS-232 RJ-45HP 16-port RS 232 RJ-45 port moduleAD280A
16RS-232 DB-25HP 16-port RS 232 DB-25 port moduleAD281A
Each AD279A PCI MUX 64-port adapter supports a maximum of four port modules (64 ports)
connected together. The RS-232 RJ45 port module (AD280A) and RS-232 DB25 port module
(AD281A) can be intermixed using an EBI cable. The DB25 connectors are male.
NOTE: The pin assignments on the RJ-45 ports are incompatible with the RJ-45 pin assignments
used on the older A6748A/A6749A PCI MUX products.
Cables used to connect port modules two, three, and four are known as EBI cables. Each EBI
cable is one feet (0.30480 metre) in length. The RJ45 and DB25 port modules use the same EBI
cable. The AD280A and the AD281A use the same power supply (AD280-2001A).
NOTE: The AD279A PCI MUX 64-port adapter can support 2 port modules or up to 32 port
configurations without the port module power supply. The port module power supply is required
on the third port module and the fourth port module or 33 through 64 port configurations.

Fan-Out Cable for AD278A PCI MUX 8-Port Adapter
A fan-out cable is an interface between AD278A PCI MUX 8-port adapter and RS-232 peripheral
devices. The fan-out cable has a DB78 connector at one end. This end is connected to the AD278A
PCI MUX 8-port adapter. The other eight ends of the cable have DB25 male connectors. Therefore
an F-F gender changer is required if the device cabling uses male DB-25 connectors.
Figure 1-5 shows AD278A PCI MUX 8-port adapter fan-out cable.
Figure 1-5 Fan-Out Cable for AD278A PCI MUX 8-Port Adapter
The RJ-45 to DB-25 adapter cables can be built and used to connect the fan out cable ports to
various peripheral devices.
Power Supply for Port Modules
The first and second port modules connected to a AD279A PCI MUX 64-port adapter do not
require power supply. However, the third and fourth port modules require seperate power
supply. The power supply requires 110-220 V and 50-60 W AC input.
Figure 1-6 shows the external power supply (AD280-2001A) for the port modules.
