Introduction
This manual is an installation guide for the CASI-RUSCO Models 950 and
960 Proximity Perfect™Readers. The Model 950 Reader is intended to be
mounted on the surface of a window mullion or door frame, and it is
specially tuned for installation on metal. The Model 960 Reader is
intended to be mounted directly on glass and has double-sided indicators
and a bi-directional read range.
Both readers consist of a metal boxed interface unit to be mounted in a
secured area and one or two compact read heads that communicate over
total cable lengths of up to 400 to 500 feet. The interface unit contains the
circuitry that drives any combination of up to two Model 950 or 960 read
heads. This performance is based on read heads manufactured after
September 1, 2000.
NOTE: For read heads manufactured prior to December, 2000, and mixed
heads, refer to the section entitled “Pinouts” beginning on page 15. The
cable length for read heads manufactured prior to December, 2000, remains
at 15 feet.
Product Features
The CASI-RUSCO Models 950 and 960 Proximity Perfect Readers offer:
• State-of-the-art architecture.
• The ability to read all ProxLite, ISO ProxLite, and Entrée badges.
• Miniature, unobtrusive read head design.
• Badge read range up to 4.3 inches (110 mm) for a Model 950 and 5.5
inches (140 mm) for a Model 960.
• A maximum of two 950 and 960 read heads may be connected to a
single interface unit, both acting as the same reader.
• If two read heads are used, each can be mounted up to 200 feet from
the interface, for a total of 400 feet of cable between the two heads.
• The Model 960 read head mounted on the secured side of a window
canreadbadgesontheunsecuredside.
• DIP switches allow all Models 950 and 960 Readers to operate in one
of four distinct operating modes: Wiegand, F/2F, Supervised F/2F,
and Silent Supervised F/2F. Silent Supervised mode is ideal for
installations where no audible or visual indication of communication
loss with the microcontroller is desired at the reader.
• In the unsupervised modes (Wiegand and F/2F), the reader
communicates with the microcontroller over a uni-directional
Wiegand or F/2F data link that carries Proximity Perfect badge data
only.

2 Model 950/960 Proximity Reader
• In the Supervised modes (F/2F and Silent F/2F), the reader
communicates with the microcontroller over a bi-directional F/2F
data link that carries the following:
• Proximity Perfect badge data
• Supervision messages
• Exit request and door contact status
• Microcontroller acknowledgments and commands
• Intelligent bi-directional communication between the interface unit
and microcontroller, which can be accomplished up to 5,500 feet
(1676 m) over 22 AWG telephone cable.
• The interface unit has an integral beeper along with a provision for
driving an installer-supplied remote +12VDC beeper.
• Weatherproof read head (Model 950 only).
• Built-in tamper switch on the interface unit with provisions for
connecting additional installer-supplied tamper switches.
• The interface unit has a red LED, the read head has one yellow, and
one green LED.
• Standard 12V operation.
• Rugged molded ABS construction with integral backplate.

Switch Settings
Two banks of four DIP switches located inside the interface unit are used
to select the reader power level, operating mode, and internal beeper
sound level.
CAUTION: Power should be removed from the reader while switch settings
are changed.
Selecting Reader Power Level
The reader’s power requirement is selected using four DIP switches. The
optimum power level will vary with each installation. Higher power
levels give improved read range for Proximity Perfect badges; while
lower power levels allow greater cabling distance between the reader and
the microcontroller. A detailed explanation is provided below. The
reader’s power requirements are unaffected by the connection of a second
read head to the interface unit. The figure on the next page shows the
location of the DIP switches. The tables that follow give the switch
settings, read ranges, and cabling distances.
Explanation of Read Range/Cable Distance/Power Level:
Maximum badge read range is determined by the distance at which the
field transmitted by the reader is just strong enough to wake up the
badge. Therefore, the higher the reader’s transmission power, the greater
the badge read range will be. The trade-off for increased read range is a
decrease in the maximum cabling distance between the reader and the
microcontroller. The trade-off between read range and cabling distance is
common to all proximity badge readers. The power selection switches on
the Models 950 and 960 Readers allow the optimum power setting to be
selected to suit individual installations.
For example: On the high power setting, giving the greatest badge read
range, the reader typically requires 200mA of supply current from the
microcontroller. If there is 1,000 feet of 22 AWG cable between the reader
and the microcontroller, the total reader power and power return path is
2,000 feet. Since 22 AWG cable has a typical resistance of 16 ohms per
1,000 feet, the total resistance in the reader’s power and power return
wire is 32 ohms. By Ohms Law (V=IR), it follows that the total voltage
dropped in the reader power and power return wires will be 6.4V
(6.4V = 200mA x 32 ohms). Therefore, the reader supply voltage will drop
from 12V at the microcontroller to 5.6V (12V - 6.4V) at the reader. Such a
supply voltage is too low for the reader to function reliably.

4 Model 950/960 Proximity Reader
If the low power setting is selected, the badge read range is reduced.
However, the reader now typically requires only 75mA of supply current;
therefore, the voltage drop in the power and power return wires is much
less. In this case, the reader supply voltage will only be reduced to 9.6V,
high enough for reliable operation.

CAUTION: Power should be removed from the reader while switch settings
are changed.
The table below gives the switch settings for the three power levels.
The table below gives the read ranges for each of the readers based on the
power level settings and whether one or two read heads are connected to
the interface unit. If a Model 950 and 960 read head are connected to the
same interface unit, refer to the read ranges in the Dual 950 and Dual 960
columns. All read ranges are typical maximums, measured with up to 20
feet cable length between interface unit and read head.
in = inches
mm = millimeters
NOTE: The above distances are typically valid up to 100 feet between
interface and read head. Beyond 100 feet, the range decreases to "almost
contact" at 500 feet.
