!

Changes or modifications not
expressly approved by Telxon for
compliance could void the user’s
authority to operate the equipment.

This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant to
Part 15 of the Federal Communications Commission
(FCC) rules. These limits are designed to provide
reasonable protection against harmful interference
when the equi pment is operated in a commercial
environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not
installed and used in accordance with this user’s
guide, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area is likely to cause harmful interfer­ence, in which case users will be required to correct
the interference at their own expense.

DOC statement

This digital apparatus does not exceed the Class A
limits for radio noise emissions from digital apparatus
as outlined in the Radio Interference Regulations of
the Canadian Department of Commun ications (DOC).

This Class A digital apparatus meets all requirements
of the Canadian Interference-causing Equipment
Regulations.

Cet appareil numerique de la Classe A respecte toutes
les exigences du Reglement sur le material broilleur
du Canada.

Overview of the Connection Manager

The Telxon Connection Manager is designed primarily
for use in small stores with less than 12,000 square
feet. It acts as a communication link between the
store’s host computer and one or more Portable Tele­Transaction Computers (PTCs). The Connection
Manager can send data to and receive data from the
host and the PTCs.

The Connection Manager is wired to the host com­puter via an RS-232 serial cable or can be connected
to an Ethernet network to which the host is connected.
The Connection Manager establishes wireless
communication links with PTCs used throughout the
store. The PTCs, which can consist of any combination
of up to eight PTC-921 DOS and/or PTC-960LE units,
and the Connection Manager communicate with each
other via their internal MiniNet 2.4 radio modules.

Light-emitting diodes (LEDs) on the Connection
Manager’s front panel indi cate the status of power
input, error conditions, and communication
connections.

Processor

The Connection Manager’s 66-MHz AMD Elan SC400
processor is fully IBM PC compatible. It provides
exceptional processing speed and is designed for low
power consumption.

Operating system

The Connection Manager uses the MS-DOS 6.22
operating system (ROM version) .

11

Memory

The Connection Mana ger ha s two ty pe s of memory:
read-only memory (ROM) and random access memory
(RAM).

ROM

The Connection Manager comes with 256 kilobytes
(KB) of flash BIOS programmable read-only memory.
It is used to store the operating system, BIOS, and
flashing kernel.

RAM

The Connection Manager has 4 MB of random access
memory. RAM is used to store data the Connection
Manager needs while it is running. One MB of RAM
is reserved for running the operating system and your
application.

Data stored in RAM can be easily read, written, and
changed. It is also volatile. All data in RAM will be
lost if power to the Connection Manager is terminated.

Radio

The Connection Manager contains a MiniNet 2.4
low-power frequency-hopping radio module. This
radio allows the Connection Manager to interactively
communicate in real-time with PTCs on a radio-based
local area network. It provides secure, interference­free communication and does not require a license for
operation.
