Chip antenna example

Cypress Suprex® RF Series - Setup and Pre-installation

Antenna orientation and field placement:

See examples below for Suprex® RF units with dipole antennas and “chip” antennas.The orientation of the dipole
antenna is critical for performance. The antenna should always be oriented vertically. Orientation of Suprex® RF units
with an internal “chip” antenna is not as critical.

Radio frequencies in the 2.4 GHz bands have characteristics that require a direct line of sight (LOS) between the
transmitter and receiver. For best performance the antennas of the Central and Remote should “see” each other without
obstructions.

There are limited exceptions in which the signal will still pass between the transmitter and receiver without line of sight
placement. In some cases, the communication path will work but at a reduced distance.

For outdoor installations: When possible, place the units on the exterior of buildings to reduce interference. Repeaters/
Boosters are available if needed.

Final Field Installation Checklist:

•

The Central unit and access control panel should have a common ground.

•

The Remote unit and card reader should have a common ground.

•

The top of each unit (where antennas are located) should point up toward the sky.

•

The Central and Remote units should be installed level relative to each other.

•

There should be a direct line of sight between Central and Remote units (if there is no direct line of sight, a
Repeater unit is recommended).

•

Both the Central and Remote units should be mounted high enough to avoid interference from obstacles
(vehicles, trains, buildings, trees, etc.).

•

Metal mounting surfaces are not recommended. If use of a metal surface is unavoidable, space unit as far from
metal surface as possible using non-metal spacer.

Unpacking:

Remove covers from units and check interior for any shipping damage. Remove any packing material if present.
Inventory any included parts (depending on model) such as antennas, coaxial cables etc.

Bench Testing:

Before installing the units in the field they should be assembled and tested at a convenient benchtop location. This will
make it easier to verify / change settings and check operation when both units are visible.
This is also an opportunity to become familiar with the system if this is the first use of the Suprex system. It is much more
difficult to set up and test the units when they are several thousand feet apart.
Both units will need to have the antenna and a suitable power supply connected. For testing purposes, the units can
share the same power supply.

Basic Bench Test:

During initial setup, refer to the Run / Configuration mode settings (pgs 7-9).

1.

Connect a suitable power supply to both units. Each unit should be provided with 8 - 16 Volts dc and approx 300mA.
Units should be separated by a minimum of 24 inches.

2.

Apply power. After about a 1-2 second delay, the Diagnostic LED on both units should flash green. The supervision
relay (Relay 3) activates when the units are communicating. Note: Supervision relay is disabled by default (see pgs. 7-9).

3.

Touch a jumper wire from the Ground connection to the Relay 1 input on the Central unit. Relay 1 on the Remote unit
should activate with an audible click.

4.

Units are shipped from the factory set for the Wiegand data format. If a different format is required, set the DIP switch to
the required reader and panel format (see pgs. 7-9)

5.

If a reader & panel are accessible, connect the reader to the Remote unit & the Central unit to the panel to verify card
reads are accepted by the access control system. If troubleshooting is necessary, it is easier with units in close proximity.

6.

Once these steps are completed, the units are ready for installation at their permanent locations.

7

LED DIAGNOSTIC INDICATOR

The LED Diagnostic indicator provides information on the operational status of the unit.

If the units are not communicating, viewing the diagnostic indicator LEDs may help to determine the
nature of the problem. See also Troubleshooting, page 13.

•

If Central or Remote diagnostic LED is not illuminated:

If the LED(s) are not illuminated on the unit(s), the unit is not powered or there is an electrical problem.
When power is properly applied, the Diagnostic LEDs will be illuminated to show a status below:

•

If the Central and Remote unit LEDs are flashing green:

When power is properly applied, and there is communication between the Central and the Remote, the
Central and Remote unit LEDs will flash green after every polling cycle. The speed will depend on how
many expansion units are connected (about 1 flash per second with 7 EXPs).

•

If the Central or Remote unit LED alternates between green/red:

There is no communication with the partner unit.

•

If the Central or Remote unit LEDs are solid green:

If the unit is in Configuration Mode, the settings have been successfully applied, it is safe to power
cycle the unit and switch back to Run Mode. If the unit is in Run Mode, one of the EXPs is not
communicating properly. Check that all connected EXPs are powered and properly connected. (For

details on setting Configuration Mode, see pgs. 7-9.)

OPERATING MODES

Wireless Suprex products have 3 operating modes: Run Mode, Configuration Mode, and Test Mode.

•

Run Mode: The units are factory-shipped in Run Mode. Run Mode is used during field operation of units.
Run Mode allows changing of common settings without the need to power-cycle the units. Factory-set
defaults can be changed. Default settings:

•

Units are set to operate as 1 Remote and 1 Central unit

•

Supervision relay is disabled

•

Pullup resistors are disabled

•

Number of EXP Expansion Modules is set to 0

•

Configuration Mode: Switch to Configuration Mode to change the link type and interface type. Default
settings:

•

Default interface type is Wiegand

•

Link type is pre-set based on the Suprex model

•

Test Mode: Test Mode is used for troubleshooting the reader/panel connection to the Remote/Central
unit. In Test Mode, DIP Switches 3-8 operate as if in Run Mode. Either a single unit or both units can be
set to Test Mode; the Remote and Central units retain all their normal functionality in addition to the
following functions:

•

In Test Mode, the Central unit outputs a test card read in the selected interface type every few
seconds

•

In Test Mode, the Remote unit briefly triggers Relay 2 when detecting data of the selected interface
type

Cypress Suprex® RF Series - Using the Remote Digital Relay Inputs

This section applies only to the Remote unit, as the Central unit has only digital relay inputs. DIP
switch 2 controls whether the Remote unit uses the analog relay inputs or the digital relay inputs. By
default, DIP switch 2 is off and the Remote unit is set to use the analog relay inputs. When DIP switch
2 is in the ON position, the Remote unit is set to use the digital relay inputs. The digital relay inputs
function in the same way the analog inputs on the Remote unit function. The digital relay inputs simply
need to be connected to ground for the corresponding relay to be activated.

To active the digital relay inputs, only DIP switch 2 on the Central board needs to be enabled. DIP
switch 2 on the Remote board has no function. It may be necessary to power-cycle the Central unit for
the change to take effect.

Note: The digital relay input pins are not the same Relay 3 and Relay 4 input pins labeled on the
Remote unit. Instead, the digital relay input pins use the two “Not Used” pins on the 10 pin header. The
“Not Used” pin on the outside of the board is the new Relay 3 input pin, the other “Not Used” pin is the
new Relay 4 input pin. Use the diagram below as a reference.

For most applications the analog relay inputs are sufficient. But for instances where a significant delay
is noticed in the activation of Relay 3 and Relay 4, the end user should switch to using digital relay
inputs. The digital relay input pins are able to detect a signal change faster than the analog inputs are,
and this may eliminate the delay in the activation of the relay.

Note regarding EXP units: While DIP switch 2 is on and the digital relay input pins are enabled on
the SPX-5631 / SPX-5641 units, the digital relay inputs are also enabled on any EXP-2000 Remote
units that are connected. The digital relay input pins are on the 12 pin header and are the two “Not
Used” pins. The outside “Not Used” pin is the Relay 3 Input pin and the other “Not Used” pin is the
Relay 4 Input pin.

Cypress Suprex® RF Series - Repeater Installation

For environments with obstacles that do not allow the Central and Remote units to have line of sight, or which need
greater distances covered, a Repeater can be used. The diagram above shows the Repeater being used to get around
an environmental obstacle. The Repeater needs to have line of sight with both the Central and Remote units. The
Repeater needs only to be powered on; no other connections are necessary. The Repeater needs to be on the same
channel and network ID as the Central and Remote units.

No Communication

When the Central and/or Remote unit is not communicating with its partner unit, the status LED will flash green/red. To
troubleshoot communication issues, check the following:

•

Power:

•

Both units must be powered.

•

Ensure proper power requirements are met: Unregulated Input 8 to 16Vdc @ 300mA max.

•

Installation:

•

There should be a direct line of sight between Central and Remote units (if there is no direct line of sight, a
Repeater unit is recommended).

•

The Central and Remote units should be installed level relative to each other.

•

Both the Central and Remote units should be mounted high enough to avoid interference from obstacles
(vehicles, trains, buildings, trees, etc.).

•

Metal mounting surfaces can affect communication as well as range. If use of a metal surface is
unavoidable, space unit as far from metal surface as possible using a non-metal spacer.

•

Antennas should both point up toward the sky (refer to Antenna Orientation, pg. 6).

•

In some cases an optimal mounting location can be selected by operating one of the units on a small 12V
battery and moving the location while observing the diagnostic LED indicators.

•

Configuration:

•

Ensure both Suprex units are set to the correct link type (see Configuration Mode, pgs. 7-9).

•

Ensure Suprex units are properly paired (see pgs. 25-26).

•

Ensure the Channel and Network ID settings on the Central and Remote units match (see Radio Configuration,
pgs. 25-26).

No Data / Invalid Data

If the access control panel is not receiving valid data, check the following:

•

Basic Equipment Check:

•

Ensure the reader and the access control panel data port are functional by directly connecting the reader to the
data port and passing card data.

•

Check Suprex circuit boards for any signs of visual damage, such as burnt traces, burnt components, or
browning of the PCB; these usually indicate misapplied power.

•

Wiring:

•

Ensure there is a common ground between the Remote unit and the card reader.

•

Ensure there is a common ground between the Central unit and the access control panel.

•

Ensure Wiegand data wires are correctly connected and not reversed.

•

Configuration:

•

Ensure both Suprex units are set to the correct interface type (see Configuration Mode, pgs. 7-9).

•

Ensure the access control panel is properly configured for the selected data format.

•

Data Voltage: For a Wiegand connection, ensure Data 0 and Data 1 pins on Central and Remote units are at 5V
relative to ground. The data pins can be as low as 4.4V before failing. If any Wiegand data pin is less than 4.4V, it is

necessary to identify which device is pulling down the voltage.

•

Disconnect the Suprex from the reader/panel.

•

Maintain power on the Suprex and the reader/panel.

•

Independently measure the voltages of the Wiegand data pins of the Suprex, and of the reader/panel. If one or
both devices have 4.3V or less, try enabling the pullup resistors on the Suprex by turning on DIP switch 5.

•

If internal pullup resistors do not work, try external pullup resistors (through-hole resistor 500 ohms - 2K ohms).
To install external pullup resistors, place one end of the through-hole resistor into the +5Vdc pin on the Suprex

unit; place the other end in the low-voltage Wiegand data pin (see pg. 5).

The Cypress SPX-5631 or SPX-5641 provides additional data channels to support access control hardware such as door
strikes, tamper alarms, request to exit status, etc. These signals are sent to and from the Central and Remote units
without the need to run additional wiring. We refer to these data channels as Accessory I/O. Accessory I/O data channels
include Relay 1, Relay 2, Relay 3, Relay 4, LED, and AUX. Refer to the following pages (14-21) for details of each
Accessory I/O operation and connection. Below is a table of the Accessory I/O pairs.

Relay I/O

The Relay I/O use active low inputs. When the Relay Inputs are floating (nothing connected) the inputs are set at 5V and
the corresponding Relay Outputs will have continuity between COM and N.C. When the Relay Input is set to 0Volts
(Ground) the input will activate the corresponding Relay Output. The Relay Outputs will have continuity between COM
and N.O. when the relay is activated and will hold this state for as long as the Relay Input is set to 0Volts. The Relay
Inputs can be tested by making a jumper connection to ground and monitoring the change in continuity of the Relay
Outputs.

Relay 3 functions as an Supervision relay when DIP switch 4 is on in Run Mode; a Supervision relay monitors the
condition of the communication link between the Central and Remote units. While in Supervision mode, Relay 3 is
activated when the communication link between the Central and Remote is established and functioning. Relay 3 will
deactivate (Alarm condition) when either the Relay 3 Input on the remote is active (pulled low) OR the Remote unit is
unable to communicate with the Central unit. See APPLICATION NOTE FOR DETAILS.

LED and AUX I/O

The LED and AUX I/O use active low inputs. When the inputs are floating (nothing connected) the associated output will
be set to a high level (5V). When the input is set to 0Volts (Ground) the input will activate its associated output. All
Accessory outputs are Open Collector type and will switch to Ground when activated and will hold this state as long as
the input is set to 0Volts. Each input will have an associated output. Inputs can be tested by making a jumper connection
to ground and monitoring the associated output.

To activate the relay on the Remote unit, connect as shown below. These connections can be used to allow the Remote
relay to operate a DOOR STRIKE, GATE, or other locking hardware. The diagram below shows two methods of
triggering the relays. The first method uses a dry contact to trigger the relay. The second method shows the LED signal
triggering the LEDS.

Relays 1 and 2 are available for accessory outputs at the Remote end. Either relay can be used to provide the Door
Strike or Gate Activation function. This example uses Relay 1. The Relay Input pin is normally high (5V). When the
Relay Input pin is pulled low (0V) the corresponding relay on the Remote unit will be activated. When the relay is
activated, the Relay Output pins will change continuity from N.C. and COM to N.O. and COM (not shown in diagram).

Cypress Suprex® RF Series - Accessory I/O - Remote Relay Inputs

To activate the relay on the Central unit, connect as shown below. These connections can be used to operate a REX
switch or other signals that need to go to the access panel.

Relays 3 and 4 are available for accessory outputs at the Central end. Either Relay 3 or Relay 4 can be used. This
example uses Relay 4. The Relay Input pin is normally high (5V). When the Relay Input pin is pulled low (0Volts) the
corresponding relay on the Remote unit will be activated. When the relay is activated, the relay output pins will change
continuity from N.C. and COM to N.O. and COM (not shown in diagram).

Relay 3 can used to send signals to the access panel while Supervision mode is active, but it is important to remember
that the outputs will be reversed. When Supervision mode is active and the Relay 3 Input pin is normal (5V) the relay
output pins will have continuity between N.O. and COM. When Supervision mode is active and the Relay 3 Input pin is
active (0Volts) the relay output pins will have continuity between N.C. and COM.

The following applies to these products: SPX-5631 and SPX-5641.

This application note describes the connections necessary to convey supervised contact status over a Suprex®. The
configurations described in this application note should apply to most panels which utilize supervised contacts. When

connected as described, the Suprex® provides a supervised signal to the panel interface by reading the supervised status
of the contacts connected to the Suprex® Remote unit.

Theory of operation: The access control panel is looking for a certain value of resistance connected to the supervised
contact terminals. The Suprex® Central unit will provide these resistance values locally at the panel so that the correct

supervised status is maintained. At the same time, the Remote unit must maintain supervision of the wires connected to
the relays and switches connected to the remote access point. The contact supervision is provided by the Remote unit.

The Suprex® system does this by comparing the value of programming resistor at the Central unit with the resistance seen
at the Remote interface terminals. When there is a difference in the two values, the Relay on the Central unit is activated.
There are two different

examples. One example is
monitoring a normally closed

contact at the Remote unit, and
the other example is monitoring
a normally open contact at the

Remote unit. In the examples
given, a normally closed

contact will require a
programming resistor of 1K and
a normally open contact will

require a programming resistor
of 2K. Other resistor values can

be used, but 1K resistors are
the most common. Other
resistance values will require

different value(s) for the
programming resistor(s).

Application Note on using Supervised contacts with the Suprex® RF Series

22

EXP-2000 Expansion Modules allow additional readers to connect to the access control panel using a single Suprex® RF
link. This is useful at door/gate locations with more than one card reader, such as in/out door readers or high/low gate
readers. The Suprex® RF can accommodate a maximum of 8 readers with the use of 7 EXP-2000 Expansion Modules.
Each reader requires its own data port on the access control panel.

Before using EXP-2000 Expansion modules with the Suprex® system, it will be necessary to perform a short configuration
process. This process determines how many expansion modules will be used with the Suprex® system. Each Suprex®
link can support up to 7 expansion modules.

Operation Overview:

The EXP-2000 pair of units is connected to the Suprex® pair of units via an RS-485 connection. The EXP Central units
will be daisy-chained off the Suprex® Central RS-485 port (labeled EXP+ and EXP- ). The EXP Remote units will be
daisy-chained off the Suprex® Remote unit RS-485 port (also labeled EXP+ and EXP- ). The only link between the
reader/gate location and the panel will be the Suprex® link; in this case, the wireless link.

The Suprex® and EXP-2000 Expansion Modules operate on an addressing scheme. The Suprex® pair is always address

0. The first EXP pair will be address 1, the second EXP pair will be address 2, etc. (see pgs. 7-9). When configuring the
Suprex® pair to work with the EXPs, the Central and Remote units must be told how many EXP pairs they will be working
with. The Central and Remote units of each EXP pair must be configured with their address numbers.

Setup Process: By default, Suprex® units are not configured to accommodate EXP-2000 expansion modules. To

reconfigure the Suprex® units, follow this process for both the Central and Remote units.

•

The Suprex® Central and Remote units must be configured with the total number of EXP pairs being used.

•

This is configured in the Run Mode settings and is controlled by DIP switches 6, 7, and 8.

•

Change settings on both the Suprex® Central and Remote units, as shown on pgs 7-9.

•

The EXP-2000 Expansion Module pairs need to be properly addressed with their address number.

•

The EXP address is configured by using DIP switches 6, 7, and 8 on the EXP-2000 Central and Remote units.

•

The first EXP pair will be address 1, the second EXP pair will be address 2, etc. (see pgs. 7-9).

•

Set DIP Switch 8 on the EXP Central and Remote units to set to address 1.

•

Set DIP Switch 7 on the EXP Central and Remote units to set to address 2.

•

Connect the EXP Expansion Modules into the system as indicated in the wiring diagrams on pages 23 and 24.

Suprex® Operation with Expansion Modules: Using EXP Expansion Modules does not change the normal
function of the Suprex®, with these exceptions:

•

EXP Expansion Modules are compatible only with the Wiegand interface type (does not apply to Wiegand No Filter)

•

If the Suprex® Supervision relay is enabled, the Supervision relay will deactivate (indicate alarm state) if the
communication link fails between the Suprex® pair or ANY of the the EXP pairs. (To enable Supervision relay, see Run

Mode settings, pgs. 7-9.)

•

LED Indicators with Suprex® Pair:

•

Suprex® Central or Remote status LED is solid green in Run Mode: one or more of the connected EXP units is not
communicating properly. Ensure all EXP units are powered and correctly wired.

•

EXP status LED is solid red: EXP unit is not properly communicating with the Suprex® unit. Ensure the Suprex® unit
is powered and wired correctly.

•

EXP status LED is flashing green: EXP unit is properly communicating with the Suprex®.

•

The EXP-2000 Central and Remote pair will be functionally similar to the standard Cypress SPX-1300 Suprex® system.

For more details, see the EXP-2000 manual.

DIP switch 9 controls the antenna mode of the unit. Refer to the Antenna Select diagram (see page 25) to set the
Antenna Select DIP switch to the appropriate setting. The mode the unit should set to depends on the part number. The
SPX-5631 and SPX-5641 will have the antenna selection set correctly from the factory.

The SPX-5631 should be be set to Chip Antenna setting at all times. The SPX-5631 does not include a dipole antenna
and will not function properly if the unit is set to the External Dipole Antenna setting.

External Dipole Antenna

The SPX-5641 should be set to the External Dipole Antenna setting at all times. The SPX-5641 will not be able
communicate over the full 10,000 foot range if the unit is set to the Chip Antenna setting.

Pairing

DIP switch 10 determines if the unit is in Pairing Mode. When DIP switch 10 is on, the unit will enter pairing mode (refer
to Pairing diagram above on page 25). The Central and Remote units will come paired from the factory. After pairing
mode is first entered, the radio will reboot. After one second, the LEDs display a “scanning” sequence (see diagram
below) indicating the radio is “looking” for another radio also in pairing mode.

Ambient RF Energy

When the unit is set to display ambient RF energy, the LEDs will display the ambient RF energy of the selected channel
regardless of network ID. A greater number of illuminated LEDs indicates less ambient RF energy. A lesser number of
LEDs illuminated indicates more ambient RF energy. Detecting the ambient RF energy can be used to find a channel
most suitable for operation.

Put another unit into Pairing Mode to establish a pair. Both units must be
set to the same channel and network ID to be paired. It is recommended
that the two units be near each other when pairing. Once another unit is
detected which is also in Pairing Mode, the LEDs will flicker, pause,
reset, and finally the 3 center LEDs will settle into a dim-to-bright-to-dim
pattern. This indicates pairing is successful. Pairing Mode can now be

switched off on both units for normal operation.

Cypress Suprex® RF Series - Radio Configuration (Continued)

The pairing function does not affect other units that have already been paired and are NOT in Pairing Mode. However, if
more than two units are put into Pairing Mode at the same time, the results will be arbitrary. The first two radios to
discover each other will be paired regardless of distance or signal strength.
