RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency

energy and if not installed and used properly, that is, in strict

accordance with the manufacturer’s instructions, may cause

interference to radio communication. It has been tested and found

to comply with the limits for a Class A computing device in

accordance with the specifications in Subpart J of Part 15 of FCC

rules, which are designed to provide reasonable protection against

such interference when the equipment is operated in a commercial

environment. Operation of this equipment in a residential area is

likely to cause interference, in which case the user at his own

expense will be required to take whatever measures may be

necessary to correct the interference.

Changes or modifications not expressly approved by the party

responsible for compliance could void the user’s authority to

operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise

emission from digital apparatus set out in the Radio Interference

Regulation of Industry Canada.

CHAPTER 2: Introduction

2.1 General Overview

With our 8-port and 16-port Port Manager (PM) Switches, you can control

and manage a network without having to worry about the in-band restrictions

associated with SNMP. Both models of the Switch make it possible to establish

on-site or remote communication with any piece of equipment that has an RS-

232 command port. You can access such devices without having to travel to

the installation site, even when your network is down.

Versatile Connectivity

The PM Switch provides a practical solution for applications that require

communicating with devices using dissimilar data rates. You can individually

tailor the Switch’s 8 or 16 ports for specific data rates, data formats, types of

flow control, and various other custom parameters and options.

Easy Setup and Operation

Configuring the PM Switch is simple. You can select communications

parameters or enable or disable options through a convenient menu system.

The Switch can be easily configured to fit the requirements of almost any

data-communications application.

Limited Command Access

The PM Switch is ideal for situations that require two tiers of command/

configuration security. You can individually configure the Switch’s ports

either as Administrator ports with access to all commands, or as User ports

with access to basic commands only.

Modular Design

The PM Switch’s RJ-11 jacks can be quickly and easily connected (through

RS-232 modular adapters) to computers, modems, and other LAN/WAN

hardware. The Switch is compact and occupies only one rack unit (1.75

inches) of vertical rack space.

Buffered Ports

The PM Switch has 256 KB of nonvolatile, dynamically allocated buffer

memory that prevents data from overflowing during communication sessions.

If your application requires more memory, call Black Box for technical

support; they might be able to provide you with a quote on units with 512-KB

buffers.
