Introduction

This guide shows you how to setup your MultiAccess ACS analog

communication server, two-port model MA220, four-port model MA420 or eight-

port model MA820. All three units provide the same Remote Access Server,

RAS, and modem sharing capabilities except for the number of ports each can

provide. The MA420 and MA820 are provided in a desktop and rack mountable

units where as the MA220 is provided in a desktop and wall mountable unit.

MultiAccess MA820

The MultiAccess ACS has two roles (usage), RAS and Modem Sharing.

RAS Solution: The MultiAccess can be used as a dial-in PPP Remote Access

Server in a LAN to Client environment. The purpose is to give remote nodes

(i.e., Microsoft Dail-up Networking clients) TCP/IP access to the same subnet

and LAN the ACS is installed on. Masquerading (NAT) and LAN to LAN routing

(assignment of an entire subnet) are IP networking techniques not supported by

the ACS. The supported PPP security protocol (means of communicating user

credentials between PPP end points) is PAP only.

Modem Sharing Solution: The modems in the ACS can be a shared resource on

your network, commonly referred to as a network modem pool. Computers with

network asscess to the ACS can use Telnet and get direct AT command access

to one of the modems in the ACS, for either outbound or inbound calls. A

common way to take advantage of this role is by installing Com Port Redirector

Software (i.e., Multi-Tech’s MCSI2000 for Windows) on your workstations. The

redirector adds a virtual com port to the workstation and uses Telnet to map,

redirect, the com port to a modem in the ACS. The redirector and Telnet

session replaces the UART based hardware of a PC and serial cable

connection normally found in traditional modem installations. A communication

program using this virtual com port has its data redirected to and from the

modem within the ACS, making the modem appear as if it is directly attached to

a communication port on the workstation.

Safety Recommendations for Rack Instructions

•Ensure proper installation of the MultiAccess in a closed or multi-unit

enclosure by following the recommended installation as defined by the

enclosure manufacturer. Do not place the MultiAccess directly on top of

other equipment or place other equipment directly on top of the MultiAccess.

•When mounting the equipment in a rack, make sure mechanical loading is

even to avoid a hazardous condition, such loading heavy equipment in the

rack evenly. The rack should safely support the combined weight of all

equipment it supports.

•If installing the MultiAccess in a closed or multi-unit enclosure, ensure

adequate airflow within the rack so that the maximum recommended

ambient temperature is not exceeded.

•Ensure that the MultiAccess is properly connected to earth ground via a

grounded power cord. If a power strip is used, ensure that the power strip

provides adequate grounding of the attached apparatus.

•Ensure that the mains supply circuit is capable of handling the load of the

MultiAccess. Refer to the power label on the equipment for load

requirements.

•Maximum ambient temperature for the MultiAccess is 60 degrees Celsius

(140°F).

•This equipment should only be installed by properly qualified service

personnel.

•Only connect like circuits. In other words, connect SELV (Secondary Extra

Low Voltage) circuits to SELV circuits and TN (Telecommunications

Network) circuits to TN circuits.

Hardware Installation (MA420 and MA820 only)

The MultiAccess is designed to install either on a desktop or in a standard EIA

19“ rack, and is shipped with the mounting hardware to install the MultiAccess in

the rack. If installing in a rack, use the provided mounting hardware and follow

the rack enclosure manufacturer’s instructions to safely and securely mount the

MultiAccess in the rack enclosure. Proceed to the cabling procedure.

Quick Start Guide

MA220 Mechanical Mounting (Optional)

Cabling Procedure - Back Panel

Cabling your MultiAccess involves making the proper power, phone, and

ethernet connections as described below. The MultiAccess MA420 and MA820

back panels have a fan, a power plug, POWER Switch (| / O), four or eight RJ-

11 phone jacks, an Ethernet jack, and a Command jack. The MA220

backpanel has two LINE RJ-11 phone jacks, an Ethernet, LAN 1, and a

CONSOLE jack.

Back Panel – MA420

Back Panel – MA220

1. Plug one end of your RJ45 Ethernet cable into the Ethernet (MA420 &

MA820) or LAN 1 (MA220) jack on the back of the MultiAccess and the

other end to the hub on your local network.

Caution: Before connecting to the Ethernet network, make sure that the

network to which you are connecting the MultiAccess is not a 192.168.2.x

subnet. Because the MultiAccess’s factory default IP address is

192.168.2.1, connecting it to a network that has a different device at the

same IP address would cause data interference.

If it is a 192.168.2.x subnet, connect from the Administrative PC to the

MultiAccess using an RJ45 crossover cable until the MultiAccess’s IP

address has been configured. Afterwards, connect the MultiAccess into the

network with an ordinary RJ45 cable.

2. Using a standard telephone cable, connect one end of the cable to the first

RJ11 jack (1 or Line 1) on the back of the MultiAccess and the other end to

one of your phone jacks.

Quick Start Guide

3. Continue to connect standard telephone cables to the remaining RJ11 jacks

on the back of the MultiAccess.

4 The Command or CONSOLE jack is to be used with direction from Multi-

Tech’s Technical Support Personnel .

5. For the MA420 and MA820, ensure that the MultiAccess is securely and

permanently connected to an earth ground (GND) with a ground wire of 18

gauge (18 AWG) or thicker. The ground wire needs to be installed between

the grounding screw on the MultiAccess and a permanent earth ground.

In order for the earth ground to be considered permanent, the grounding

wire must connect to the earth ground of the building’s electrical wiring

system and the ground connection must use a screw terminal or other

reliable means of fastening. The ground connection must not be as easily

disconnected as, for example, a power cord.

6. On the MA220 unit, secure the power lead from the power source to the

screw-on power connection on the backpanel of the unit.

On the MA420 and MA820 units, with the MultiAccess Power switch in the

off (Ο) position and using the supplied power cord, connect the MultiAccess

power plug to a live power outlet.

7. Place the MultiAccess Power switch to the on (|) position for the MA420 and

MA820 to turn on the MultiAccess. The MA220 does not have a power

switch.

Setting Admin PC to Startup IP Address

1. Connect a PC to your network. Record the PC’s current IP address.

2. Set the PC IP address to 192.168.2.x subnet (using any address

excluding 192.168.2.1).
