DOC statement
Notice: The Canadian Department of
Communications (DOC) label identifies certified
equipment. This certification means that the
equipment meets certain telecommunications
network protective, operational, and safety
requirements.The Department does not guarantee
the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure
that it is permissible to be connected to the facilities
of the local telecommunications company. The
equipment must also be installed using an acceptable
method of connection. In some cases, the company’s
inside wiring associated with a single line individual
service may be extended by means of a certified
connector assembly (telephone extension cord). The
customer should be aware that compliance with the
above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be made by
Telxon. Any repairs or alterations made by the user to
this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the
user to disconnect the equipment.
10

!Users should not attempt to make
such connections themselves but
should contact the appropriate
electric inspection authority, or
electrician, as appropriate.
Users should ensure for their own protection that the
electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe
system, if present, are connected together. This
precaution may be particularly important in rural
areas.
The load number (LN) assigned to each terminal
device denotes the percentage of the total load to be
connected to a telephone loop, which is used by the
device to prevent overloading. The termination on a
loop may consist of any combination of devices subject
only to the requirement that the total of the load
numbers of all the devices does not exceed 100. An
alphabetic suffix is also specified in the load number
for the appropriate ringing type (A or B), if applicable.
For example, LN = 20 A designates a load number of
20 and an “A” type ringer.
11

Safety information 2
Disposing of nickel-cadmium batteries
The nickel-cadmium batteries that are recharged by
the SC-960RL/SC-960L contain chemically active
materials that are hazardous to the environment;
therefore, they must be disposed of properly. Never
attempt to incinerate a nickel-cadmium battery; doing
so could cause it to explode. Telxon urges you to
contact the Environmental Protection Agency, the
Department of Natural Resources, a local hazardous
waste disposal agency, or the Telxon Customer
Support Center for assistance prior to disposing of
your nickel-cadmium batteries.

Overview of the SC-960RL/SC-960L 4
The SC-960RL and SC-960L Single-bay
Communication Cradles are accessories for the
PTC-960RL and PTC-960L, respectively. The cradles
work with the PTCs in two ways.
First, the cradle acts as a communication link
between the PTC and a host computer. It can send
data to and receive data from both units. The PTC
and the cradle communicate with each other through
their optical couplers and with the host computer via
a cable or modem.
Second, the cradle automatically charges a PTC’s
nickel-cadmium battery pack and a spare battery
pack when the PTC and spare pack are inserted into
the cradle. It requires approximately 12 hours to
charge both packs (plus the amount of time the PTC
spends communicating with a host computer).
Light-emitting diodes (LEDs) on the cradle’s front
panel indicate power, communication, and battery
charging status.
A modem is an electronic device that
allows the cradle to send and receive
signals over standard telephone lines.
The SC-960RL/SC-960L can be equipped with one of
six country-specific internal modems that provides
one-way or two-way communication.The cradle can
also be connected to an external modem. See
Appendix A for more information about modem
options.
The cradle can be used by itself or can be connected
directly to other SC-960RL/SC-960Ls to form a
system of up to 32 cradles.

Getting started 5
Unpacking the SC-960RL/SC-960L
Any additional accessories are
shipped separately. Each shipping box contains
•an SC-960RL or an SC-960L,
•a 12-VDC, 800-mA power pack,
•a cradle base (if your cradle was ordered as a
table-top version),
•an SC-960RL/SC-960L Read-Me-First Sheet,
and
•an SC-960RL/SC-960L User’s Guide.
See Appendices B and Cfor cable
part numbers and information. If you will be connecting the cradle to a host computer,
you need a properly wired cradle-to-host cable,
available separately.
1. Remove the cradle from the box.
2. Remove all packing material from the cradle.
Save the packaging in case the cradle is ever
stored or shipped to Telxon for service.
3. Check the contents of the package to make sure
you have received everything ordered.

Parts 6
Figures 1 and 2on pages 17 and 18 show and describe
the parts of the SC-960RL/SC-960L. The parts listed
below are not shown in either figure.
Cradle base
A cradle base is shipped with every table-top version
of the SC-960RL or SC-960L. The base holds the
cradle in place on a flat horizontal surface. It can be
permanently mounted through its four mounting
holes.
Modem module (optional)
See Appendix A for a list of available
modem modules. See page 23 for
information on connecting the
internal modem to telephone lines.
The SC-960RL/SC-960L can be equipped with an
internal modem module that provides communication
capability over standard telephone lines between a
PTC installed in the cradle and a host computer.
Either one-way half-duplex or two-way full-duplex
communication is available.
Power pack
The power pack,which provides power to the cradle,
plugs into the cradle’s power connector and into an
electrical outlet (110 volts AC in the U.S. or Canada).
It provides 12 volts of direct current (VDC) at 800
milliamperes (mA).
Each cradle, whether installed individually or as part
of a system of connected cradles, must have its own
power pack.

* This view of the SC-960RL/SC-960L shows the cradle in its wall-mount configuration.
1. These mounting holes allow table-top versions of the cradle to be secured in a cradle base and wall-mount versions to be mounted on a wall
via a standard telephone wall mounting plate. See Chapter 8 for details.
2. A 12-VDC, 800-mA power pack plugs into this connector and an electrical outlet to supply power to the cradle.
3. Sliding the power pack’s cable under this hook helps to prevent the cable from becoming unplugged.
4. If your SC-960RL/SC-960L was ordered with an internal modem, it will have an RJ-11 jack, a standard modular telephone-type jack. It can be
used to connect the cradle directly to a telephone line.
If your SC-960RL/SC-960L was not ordered with an internal modem, it can be connected to most standard external modems. You will need to
connect a cradle-to-modem cable to the cradle’s host connector and to the connector on the external modem. See Appendix B for cable
part numbers.
