Service Port (Micro USB)
8-Way MS/TP address DIP switch (CBX only)
The controller’s BACnet® MAC address can be set either electronically (USB or BACnet®) or manually using the 8-way
DIP switch.
1)
Manual setting for ease of replacement
: Setting the 8-way DIP switch to an address between 1 and 254, and
then cycling the power, will force the controller to update its MAC address to match the DIP settings. To
replace a manually-addressed controller in the field simply copy the DIP switch setting of the controller you are
replacing.
2)
Electronic setting for remote configuration
: Setting the 8-way DIP switch to all zeros will allow the MAC address
to be set electronically either locally by USB or remotely over BACnet®.
It is also possible to use manual setting for initial commissioning, and then cycling the power to force the
controller to update its MAC address to match the DIP settings. To enable subsequent electronic configuration,
set the DIP switch to all zeros. The controller will retain the manually-set address until it is electronically
overwritten.
5-Way FLX bus address DIP switch (FLX only).
This sets the address of the FLX unit on its local FLX bus.

1. APPLY POWER TO THE CBX-8R8(-H)
1.1. Set the CBX MS/TP Address
To communicate to other MS/TP devices on a BACnet® MS/TP network, the MS/TP
address must be set to a unique address within the MS/TP subnet. Where possible,
there should be no gaps between addresses. The BACnet®Instance Number must also
be unique for the BACnet®site.
The 8-way DIP switch can be used to set the MS/TP address when the device is first
powered on.
•The address is set in binary, from 1(0000001) to 127 (1111111).
•A switch moved to the center (towards the ‘ON’ mark) represents 1, moved
to the edge represents 0.
•The right-most switch (labeled “1”) is the least-significant bit; the switch on
the left (labeled “8”) is the most-significant bit.

Address 88
11111111
Address255
0000000
Software Selectable*
*Note: If it is required that the CBX-8R8(-H)’s address can be configured remotely via
BACnet® or electronically via USB, then once the CBX-8R8(-H) has been
powered up (Installation step 1.2) the 8-way DIP switch should be set to all zeros.
Setting the 8-way DIP switch to all zeros will allow the MAC address to be set
electronically either locally by USB or remotely over BACnet®.
It is also possible to use manual setting for initial commissioning, and then
cycling the power to force the controller to update its MAC address to match
the DIP settings. To enable subsequent electronic configuration, set the DIP
switch to all zeros. The controller will retain the manually-set address until it is
electronically overwritten.
Note: If no address had previously been set (e.g. when the device is received from the
factory), then a device that is powered-on with the DIP switch set to all zeros
will use the last 2 digits of its serial number as its initial address.
The MS/TP baud rate must match on all devices on the MS/TP subnet.
1.2. Connect 24 V AC Power to the CBX-8R8(-H)
For the initial configuration of the device, the controller must first be powered on.
Note: Service Port (USB connection) must not be connected until after the device is
powered on.
The CBX-8R8(-H) requires 24 V AC supplied from an externally mounted power
transformer. One conductor of the transformer must be grounded to an earth ground
to avoid damage to the controller. This conductor will be wired to the COM (common)
terminal of the controller. The wiring diagram is shown here:
Note: Ensure the 24 V AC and Common wires are correctly connected to the
controller. If the wires are swapped, it may cause damage to anything
connected to the controller.
2. CONNECT THE CBX TO THE MS/TP NETWORK
2.1. Attach RS-485 communication wires to
the MS/TP Subnet port
Wiring the RS-485 network involves connecting the A+ (95) and B- (96) terminals in a
daisy-chained configuration. One end of the network will be connected to the
Fieldbus of the Network-level controller or BACnet®router. At the other end of the
network, the last device must be “terminated” by either installing a 100 Ω … 120 Ω
resistor or, if the last device is a CBX, users can switch the MS/TP Subnet terminator
switch (located beside the MS/TP port) towards the icon. This will effectively terminate
the network. The shield (screen) must be carried through the entire network.
If the RS-485 network is wired to an eSC, then the shield will be grounded at the eSC.
If the RS-485 network is wired to a CBR, the shield must be grounded at one point on
the network as shown below:

CBX System TECHNICAL DATASHEET & INSTALLATION GUIDE
2.2. Terminate the MS/TP network
If the CBX-8R8(-H) is the last device on the RS-485 network, then its MS/TP subnet
terminator switch must be set to “in”
3. CONFIGURE THE CBX-8R8(-H) FOR
BACNET® COMMUNICATIONS
3.1. CBX-8R8(-H) Default Settings
The CBX-8R8(-H) is shipped with the following default settings:
MS/TP Address: last 2 digits of the numeric portion of the serial number*
BACnet® Instance
Number:
entire numeric portion of the Controller's serial number*
MS/TP Baud Rate: 38,400 bps
*Note CBX serial numbers are structured as “CCBX” followed by a sequential
number followed by a letter: CCBX (numeric portion) (letter)
Note If the ‘numeric portion’ of the Controller serial number ends with ‘00’ then
the MS/TP address is set to 100 rather than 0to avoid conflict with the CBR
default MS/TP address.
e.g. If the Controller serial number is CCBX727458C, the ‘numeric portion’ is
727458. In that case the MS/TP address would be 58 and the BACnet
Instance Number would be 727458.
If the Controller serial number is CCBX812300C, the ‘numeric portion’ is
812300. In that case the MS/TP address would be 100 and the BACnet
Instance Number would be 812300.
3.2. Connect CXproHD to the CBX-8R8(-H)
Connect the laptop to the CBX-8R8(-H) through a BACnet® Router such as CBR or
ASPECT® Control Engine (ACE - Matrix or Nexus Series) via Ethernet,or directly
using a standard Micro-B USB cable.
Note: When the CXproHD PC is connected to the CBX USB port for the first time,
you will be prompted to install a driver. Install “ STMicroelectronics Virtual
COM port ”, and then select the corresponding serial port in CXproHD to
connect to the CBX. If you are using Windows 8.1 this driver may not be
available by default, please contact Cylon TSG for a copy of the driver.
Once connected to the controller, it is possible to change the settings on the
controller using CXproHD - for details see the CXproHD User Guide (MAN0133)
available from the Cylon support site (http://support.cylon.com).
Note: It is not required to change the Site Number or Comms Controller preset
values. It is however recommended to match the Field Controller address
with the MS/TP Station address (see below).
3.3. (If required) Set Device Instance & MS/TP
Address
Note: This is only possible if the MS/TP address switch is set to Zero.
3.4. Confirm or set MS/TP parameters
MS/TP Baud Rate is the Baud rate at which all the other devices on the subnet
(Fieldbus) are communicating. All devices must be configured for the same baud
rate for communications on the subnet.
Device ID is the BACnet device instance number. Every BACnet controller within
the site must receive a unique BACnet instance number to ensure proper
communications. This BACnet instance number should be unique even across
subnets. By default, it is set is set to the entire numeric portion of the Controller's
serial number. See the Cylon BACnet® Manual (MAN0106US) for further
information.
Device Name is the user-assigned name for the controller. This is not necessary
for BACnet communications; however, it is useful to name each controller for
organizational purposes.
APDU Timeout Seconds leave this at the default setting of 3 seconds.
MS/TP Station is the device MS/TP address. This is the unique address users
must give each controller on the subnet (Fieldbus).
MS/TP Max Masters is the maximum address that this controller will poll when in
the “poll for masters” state. Because this is a BACnet master device, it will go into
this state to search for the next BACnet master device to pass the token to. To
optimize the speed of the network, it is recommended that the last master device
on the subnet be set at the maximum MS/TP address on the network. For
example, if the last device on the subnet (Fieldbus) is the CBX at address 63, then
users would set the MS/TP Max Masters to 63. This will speed up
communications as it will not go into the “poll for masters” state and immediately
pass the token back to the eSC or CBM at MS/TP address 0.
See the Cylon BACnet® Manual (MAN0106US) for more details regarding this
functionality and for other tips on optimizing the BACnet network.
4. CONNECT THE CBX-8R8(-H) TO FLX
UNITS
The I/O capabilities of a CBX-8R8(-H) can be extended by the addition of FLX-8R8
and FLX-8R8-H devices.
These are connected to the CBX-8R8(-H) by means of a standard module
interconnector (FLX bus connector), one of which is shipped with each FLX device.
4.1. Set the FLX address
Each of the FLX units connected to a single CBX must have an address that is
unique on that CBX’s FLX bus. The address is set by the 5-way DIP switch.
The terminals on a FLX unit will be accessible within the CBX Strategy with point
numbers prefixed by this address as illustrated below:
Inter-module bus
Address DIP switch setting Point numbers
00001

Place the devices side-by-side and place the FLX bus connector into
the two adjacent sockets at once.
The end device on a CBX set (either a FLX device or the CBX itself if no FLX devices
are connected) must have a terminator inserted into its interconnector socket.
One terminator is shipped with each CBX-8R8(-H) device.
4.3. (If required) Set up FLX bus extension
If a FLX device cannot be located beside a CBX device or another FLX device then
The FLX bus can be connected by cable using two FLX-RMC Remote Module
Connectors, sold separately.
Connect cables to the two supplied FLX-RMC screw-terminal connectors as shown
above with the appropriate length of cable.
Note: Use Copper or Copper Clad Aluminum conductors only. Multiple wired
connections can be used between FLX modules, but the total FLX bus FLX
bus length must not exceed the following lengths:
Cable gauge
Max length
AWG 18
30 m / 100 ft.
AWG 22
15 m / 50 ft.
Remove the Interconnect (if installed) from the right-hand side of the FLX or CBX
where the RMC is to be installed.
Slide one RMC connector into the T-slot of the CBX or FLX at the point at which
the BUS is to be extended.
Replace the Interconnect
Slide the other RMC connector into the Left-Hand T-slot of the remote FLX.
Insert the second interconnect

Resistance Input mode (Passive Input)
Passive Inputs are all those devices that vary in resistance, including switch
contacts. These all require a current supplied by the CBX-8R8(-H) terminal so that
this resistance can be measured.
The passive sensor types supported by the CBX-8R8(-H) are:
•Pre-programmed Passive Temperature Sensors.
•Potentiometer (normally used as a 0 to 10 KΩ or a 1 KΩ to 11 KΩ variable
resistor to give a 0 to 100 % output).
•Volt-Free Digital Input (the controller strategy measures the contact resistance
and gives a 0or 1output).
•Straightforward Resistance measurement. This can be used with the Make
Linear block to give a temperature output for temperature sensors that are not
factory pre-programmed into the CBX-8R8(-H).
In CXproHD simply select ‘ Resistance ’ sensor type in the Point Module and select
Pulsed in the Advanced parameters (the Pulsed option increases accuracy by
eliminating any self-heating in the passive temperature sensor, while the
Continuous option can trade absolute accuracy for speed).
In Passive Input Mode the Uniputs™ and Universal Inputs configure like this:
Note: The reference voltage can be pulsed or continuous, using the solid state
switch.
A pulsed reference gives optimum accuracy by eliminating self-heating in
the sensor, and this is the default setting.
UniPutTM 24 V AC Detection
If 24 V AC is connected to a Uniput™ terminal, then the 24 V AC Detect circuit will
detect this and will open switch SW1. SW1 stays open for the duration of the 24 V
AC state. When 24 V AC is removed from the Uniput™ terminal then the short
circuit or open circuit states can again be detected.
Voltage input mode (Active Input)
Note: Input Impedance for Universal Input terminals is 130 kΩ.
Input Impedance for Uniput™ terminals is 40 kΩ.
The 0 … 10 V input is used for Active analog and binary measurements. ‘Active’
means that there is no current supplied by the CBX-8R8(-H) for the sensor, as the
signal is generated completely by the Sensor.
The ‘mV’ sensor setting gives a value between 0and 10,000, which represents
voltage in mV.
In 0 ... 10V Input Mode, the Uniputs™ configure like this:

CBX System TECHNICAL DATASHEET & INSTALLATION GUIDE
Current Input mode (Active Input)
The Current Input is used for 0 ... 20 mA or 4 ... 20 mA Active sensors.
4 ... 20 mA scaling can easily be achieved using CXproHD by entering range
values in the Point Module ‘ Advanced ’ parameters.
Output modes
UniPut™ terminals can generate an output as follows:
Analog Output 0 ... 10 V, 20 mA, 12-bit resolution
Digital Output 0 ... 10 V, 20 mA
Relay Contacts with ability to switch up to 24 V AC
Maximum Load: 24 V AC, 2 (1) A resistive (inductive) for all relay contacts
Analog 0 … 10 V output mode
In Analog 0 ... 10 V output Mode, the UniputsTM configure themselves like this:
where the D/A is the digital to analog converter. All circuitry is fully protected
against 24 V AC.
Digital 0 … 10 V output mode
In Digital 0 ... 10 V output Mode, the Uniputs™ configure in the same way as for
analog:
In this mode the output toggles between the voltages defined as “ON” and “OFF”.
Relay Mode
In Relay mode the UniputsTM are configured with a single relay common for each
half of the terminals:
Auxiliary Power outputs
The CBX and FLX modules each have two 18 V DC outputs, for I/O devices that
require loop power.
For 3-wire connections return can be through any COM terminal, but it is
recommended that Auxiliary power wiring is through terminal 14, the COM
between the two Auxiliary power terminals.
The DC output terminals provide a minimum of 18 V DC, but the combined load
(on each IO module) must remain below 60 mA.
Using a Keypad with the CBX
A CBT-STAT or UCU Room Display keypad can be connected to the CBX at the
CBT-STAT port.
Note: If UCU Room Display is used, refer to the DS0064 UCU10FC/K for the
corresponding Strategy Point Setup.

Output Override
HOA variants (CBX-8R8-H, FLX-4R4-H and FLX-8R8-H) include hardware override
switches for each of their outputs. The override controls are located behind the
flap on the front of the device:
CBX-8R8-H
FLX-4R4-H FLX-8R8-H
And consist of a switch and a rotary knob for each output:
The channel number corresponding to the switch is shown directly below the switch.
The switch can be set to one of 3 positions:
When a switch is set to the
Centre position
the
corresponding output channel is set to Auto mode – the
output is controlled by strategy.
The rotary knob has no effect in this mode.
When a switch is set to the
Bottom position
the
corresponding output is forced to Off – both the strategy
setting and the rotary knob have no effect.
When a switch is set to the Top position the corresponding
output is set to Manual mode
•for digital outputs, the output is forced on
•for analog outputs the rotary knob setting controls the
output value.
Note: Manual position is supervised, i.e. the strategy is
aware of the manual value.
The Controller Strategy can determine if an override is in place is by connecting to
the Override point on the output module:
The value of the Override point will be '0' when the output is active and ‘1’ when
the point has been manually overridden. This allows the strategy to react to the
fact that a point has been overridden.
Note: The corresponding terminal LED will indicate the override condition.
