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.
4
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
Page 12
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.
12
Page 13
Entering data
Data can be entered into the Connection Manager via
its MiniNet 2.4 low-power frequency-hopping radio
module or through its RS-232 COM1 and COM2
serial ports or Ethernet port.
Storing data
Data entered into the Connection Manager can be
stored in the PTC’s RAM, on the internal 4-MB
IDE-compatible solid-state hard drive, or on 3.5-inch,
1.44-MB, high-density floppy diskettes (if your
Connectio n Manager was ordered with the o ptional
floppy drive).

Maintaining the Connection Manager
The Telxon Connection Mana g er is we ll con struct ed
and durable; however, it is a precision electronic
device and must be treated as such. Follow the
guidelines in this chapter to ensure reliable service.
Operating conditions
Although the Connection Manager is designed to
resist dust, dirt, and moisture, it should not be used
in excessively dirty or moist conditions. Operate the
Connection Manager only in temperatures between
32 degrees F (0 degrees C) and 122 degrees F (50
degrees C).
Handling the Connection Manager
Do not open the Connection Manager. No user-
•
serviceable parts are inside.
Do not supply power to the Connection Manager or
•
attempt to transmit data unless the antenna is
connected.
9
Make sure the Connection Manager is disconnected
•
from power before connecting or disconnecting any
cables.
Make sure the correct cables are used when
•
making connections.
Protect the Connection Manager from excessive
•
heat, cold, moisture, and harsh, dirty environments.
Do not leave the Connection Manager where
•
moisture can condense on it.
21
Page 22
Moving the Connection Manager
Follow these steps if you need to move the Connect ion
Manager or prepa r e it for shipment.
Disconnect the AC adapter from the electrical
1.
outlet and the Connection Manager.
Disconnect the antenna.
2.
Disconnect all other cables.
3.
If you are moving the Connection Manager a short
distance (to a new location in the same building for
example), you do not need to use a pack in g box.
Exercise care as you move the Connection Manager
to its new location; then follow the procedures in
Chapter 8 to reinstall the unit.
If you are shipping the Connection Manager, use the
original packing material and container, if available .
Otherwise, use a sturdy carton and adequate packing
material to protect the unit during shipment.
Cleaning the Connection Manager
Clean the outside of the Connection Manager
periodically with a soft cloth moistened with a mild,
non-abrasive cleaner, such as Winde x. Do not use
solvents or abrasive cleaners. Allow the unit to dry
thoroughly before reconnecting power.
If the Connecti on Manager becomes extremely dirty
or if liquids, dirt, or other foreign materials get inside
the case, contact your Telxon service representative.
22
Page 23
Storing the Connection Manager
• Do not store the Connection Manager in tempera-
tures below –22 degrees F (–30 degrees C) or above
140 degrees F (60 degrees C).
• Do not store the Connection Manager in a damp or
humid environment (over 95% noncondensing).
Pack the Connection Manager in the original packing
material or in a padded box and put it in a safe place
away from dust, dirt, humidity, and excessive heat or
cold.
Servicing the Connection Manager
Do not attempt to service the Connection Manager.
Only a trained T elxon technician may service the unit.

Telxon service representative.
24
Page 25
A PTC fails to communicate through the
Communication Manager
• Make sure the PTC is on.
Make sure the Connection Manager is receiving
•
power. Check the AC adapter connections at the
Connection Manager and the electrical outlet.
• If the PTC still fails to communicate, contact your
Telxon service representative.
The Status LED glows solid green
If the Connecti on Manager’s Status LED glows solid
green, an error has occu rred . Contact your Telxon
service representative.
