2.1.1 General
Please read this before using the CC320 family of products. If in doubt, contact your distributor
or Gardasoft Vision.
The CC320 must not be used in an application where its failure could cause a danger to personal
health or damage to other equipment.
If the equipment is used in a manner not specified by the manufacturer, the protection provided
by the equipment may be impaired.
2.1.2 Electrical
The user must ensure that the potential difference between any combination of applied signals
does not exceed the supply voltage. WARNING: Higher voltages may cause a danger to personal
health.
The CC320 does not have complete tracking isolation of inputs and outputs.
Transients caused by inductive loads must be suppressed external to the CC320.

3Getting Started
Read the sections on Safety and Operation and check the CC320 fulfils your requirements.
Mount the CC320 as described in “Mechanical Fixing” using a DIN rail or the mounting holes.
Connect the CC320 as in the section on Connections. When the CC320 powers up it should show
two alternating lines on the display to indicate that it is operating properly. Three indicator LEDs
on the outputs should be pulsing in sequence every second.
Check that inputs and outputs are working correctly as described in Troubleshooting.
If required, connect Ethernet to the CC320 and set it up according to the Ethernet section.
Read the section on “Operation.” Use the keypad, a web browser or the CC320 demo program
(available from www.gardasoft.com) to configure the unit.
Visit www.gardasoft.com for Application Notes giving additional information on the use of the
CC320.
Throughout this manual, references to the CC320 refer to all variants in the CC320 range unless
otherwise stated.
The symbol “s” is used to indicate seconds, “ms” for milliseconds and “us” for microseconds.

4Mechanical Fixing
The CC320 does not have an IP rating and should be mounted so that moisture and dirt cannot
enter the unit.
The operating temperature range is 5octo 60oc.
The CC320 can be mounted onto a panel using the threaded holes in the base, see diagram
below. The PP703 kit is available for mounting the CC320 on a DIN rail. The top drawing shows
the optional DIN rail fitted. Dimensions are in millimetres.
The CC320 enclosure is a fire enclosure as long as the following conditions are met:
•The Ethernet connector must not be facing downwards
•The mounting holes on the underside must be covered or have a screw fitted.

5Connections
5.1 General
All connections except Ethernet are available on screw terminals.
5.2 Power Supply
The power supply must be 12VDC to 24VDC regulated. The maximum current required is
100mA. The maximum heat dissipation is 2.4W.
5.3 Digital Inputs
The state of each input is shown on an LED next to the connector.
The inputs have a common negative connection, in two groups of four.

The operational details are shown in the table below:
Connector Function
Open Drain Output Details
The voltage across the output must
not be greater than 24V and the
output can only sink up to 50mA.
If the output is shorted to a voltage
higher than 5V then the output may
be damaged.
Do not draw more than 50mA from
the +VE connections as this can
affect the internal operation of the
controller.
GND1 Common 0V for outputs 1, 2, 3, 4
OP1 Output 1 open drain
OP2 Output 2 open drain
OP3 Output 3 open drain
OP4 Output 4 open drain

OP7 Output 7 open drain
OP8 Output 8 open drain
+VE Low power regulated output. Maximum
source current 50mA.
Note that the +ve signals are low power supply outputs. These are just to be used for low current
pull ups.
5.4.1 Ethernet Connector
The RJ45 Ethernet connector requires a straight through cable to connect into a network switch,
hub or router. It runs at 10Mbits per second.

6Operation
The CC320 Trigger Timing Controller has eight digital inputs and eight digital outputs.
All outputs operate independently and are configured separately. Configuration is very flexible to
provide solutions for a wide variety of timing problems.
The configuration can be saved in non-volatile memory so that the CC320 resumes operation
after a power cycle.
The state of each input and output is shown on an LED next to the connector. Pulses are
stretched – a 10us pulse is shown as a 100ms pulse on the LED, so that it is visible to the user.
6.1 Input Modes
All inputs are general purpose trigger inputs except for IP1 and IP2, which can be used for an
encoder or as general inputs.
6.1.1 Encoder Operation
The CC320 supports two types of encoder.
Mode Connections Operation Max
frequency
EN 1 - one
wire encoder
IP1 is QEA Simple encoder provides position
information. All movement is
assumed to be forward.
700KHz
EN 2 – two
wire encoder
IP1 is QEA
IP2 is QEB
Quadrature encoder provides
position and direction information.
200KHz
For 2 wire encoders the CC320 correctly handles reversed movement. When the belt is in a
reversed position:
•the letter “b” is displayed on the front panel
•triggers for PEt and PEE modes (see below) are ignored
•output pulses in PtE, Pet and PEE modes are not duplicated
6.1.2 Free Running Trigger
An internal input (IP0) can be used as a periodic trigger.
The following parameter can be set.
Parameter Use
Period The period (inverse of the frequency) of the simulated
trigger. 0 disables the free running timer.
For example a period of 20ms could be set, which would result in a 50Hz trigger. This can be
used to trigger pulses on any of the outputs.

6.2 Output Modes
Each output operates independently. By combining which outputs are triggered by which inputs
and which mode each output is in, it is possible to configure complex sequences of operation.
Several outputs can be triggered by one input to give synchronous operation, or from separate
inputs to give asynchronous operation of different functions.
For each output, the following parameters can be set.
Parameter Use
Mode Specifies how the output operates.
Input Specifies which input is used for triggering. An output signal OP1 to
OP8 can also be used as a trigger. This parameter can be:
0 for the free running timer
1 to 8 for IP1 to IP8
9 to 16 for OP1 to OP8
Gate Input Specifies an input which enables/disables the output. This is also used to
specify the number of pulses in “burst” mode. This parameter can be:
0 for none
1 to 8 for IP1 to IP8
9 to 16 for OP1 to OP8
<number of pulses> for burst mode
Pulse Delay Specifies the delay from trigger to pulse output. This can either be a
time period or a number of encoder pulses, depending on the mode.
Pulse Width Specifies the width of the pulse output. This can either be a time period
or a number of encoder pulses, depending on the mode.
Retrigger time The retrigger time is the minimum time from when an output is
triggered to the next time. This can be used to debounce noisy inputs or
when a product sensor fires more than once for one product. The
retrigger time uses the same dimension (encoder pulses or time period)
as the Pulse Delay.
Flags Specifies other options.
When pulsing, the Pulse Delay and Pulse Width parameters can either be fixed times or can be a
number of encoder pulses.
The following operating modes are available for each output. The Mode Number is used for
Ethernet commands. The Mode Name is used when configuring using the keypad.

Mode Mode
Name
Operation
0 OFF The output is set off. If the output is inverted (flag O is set) then the
output is logic 1, otherwise logic 0.
1 On The output is set high (on). If the output is inverted (flag O is set) then
the output is logic 0, otherwise logic 1.
2 Ptt Pulsed output triggered by a digital input. The delay and pulse width are
set as fixed times.
3 PtE Pulsed output triggered by a digital input. The delay is a fixed time. The
pulse width is a number of encoder pulses.
4 PEt Pulsed output triggered by a digital input. The delay is a number of
encoder pulses. The pulse width is a fixed time.
5 PEE Pulsed output triggered by a digital input. The delay and pulse width are
a number of encoder pulses.
6 Pd Pulse divider. Every <Pulse Delay> trigger pulses, the output is pulsed
for <Pulse Width> time.
7 Enc Pulsed output triggered by encoder pulses. The output is pulsed for
<Pulse Width> encoder pulses with the pulses separated by <Pulse
Delay> encoder pulses. The Input and Gate Input parameters are not
used.
8 bur Burst output. When triggered, <Gate Input> pulses are output. Each
pulse is <Pulse Width> long and the time between the end of one pulse
and the start of the next is given by <Pulse Delay>. The maximum
number of pulses that can be output is 250.
9 FrE Outputs a constant high frequency square wave. The frequency is
configurable. Further details available from Gardasoft.
10 buF Buffer an input by making the output the same signal as the input. If
there is gate input set, then the gate input signal enables the output – if
the gate input is off then the output is off. Flag O inverts the output and
Flag G inverts the gate input.
The output can be delayed by a fixed time given by the <Pulse Delay>
parameter. Note that any Gate Input is applied before the delay.
The E flag can be set to indicate when the output changes state.
11 buE Same as buF mode, except the output signal can be delayed by a given
number of encoder pulses.
12 brE Same as bur mode, except the pulse width and pulse spacing is a given
number of encoder pulses. (V017 firmware onwards)

Each output also has the following flags which specify other options. For Ethernet commands,
multiple flags can be set by adding the flag values together.
Flag
value
Flag
Name
Operation
when flag = 0
Operation

1 I Trigger off leading edge of
input.
Trigger off trailing edge of
input.
2 O Output is normally low,
going high when pulsing.
Output is inverted. It is
normally high, going low
when pulsing.
4 G If a gate input is specified,
the input must be high to
enable triggers.
If a gate input is specified, the
input must be low to enable
triggers.
8 E No Ethernet message. Send message on Ethernet
when triggered.
16 F Triggers are ignored until
output pulse is complete.
FIFO output mode. Multiple
triggers are queued up.
32 R Resync mode disabled. Resync Mode enabled.
64 P Default to pulse in resync
mode.
Default to no pulse in resync
mode.
6.2.1 Burst Mode
In burst mode, an output is pulsed several times in response to a trigger. The periods are timed
(not encoder counts).
The following parameters are used:
•Mode is 8 for burst mode
•Gate Input specifies the number of pulses (1 to 250)
•Pulse Width specifies the pulse width
•Pulse Delay specifies the separation between the start of one pulse and the start of the next
Pulse Delay must be longer than Pulse Width.
6.2.2 Ethernet Message Flag (E)
When the CC320 is used to trigger a camera, the image processing can either be triggered by the
acquisition of an image or by an Ethernet message sent from the CC320.
When a trigger is received it is assigned a unique tag number (an incrementing number from 0 to
255). Using the GT Ethernet command and the Ethernet Message flag, the CC320 sends the tag
number in a message to the host computer to say that a trigger has occurred.
The message has the form:

Evt<channel>,<tag>
where <channel> is the channel number from 1 to 8 and <tag> is a number from 0 to 255.
Multiple tag messages may be sent in one packet, separated by “;”.
6.2.3 Resync Flag (R)
Reject gate operation usually needs to be synchronised to the original product trigger. However
image processing can take a variable length of time to complete, so rejects based on when the
processing result is available cannot be accurately timed. The Resync flag allows pass/fail results
to be re-synchronised to the original trigger.
There are two types of reject gate:
•A pulse is required to reject a product (set the P flag)
•A pulse is required to stop a product being rejected (don’t set the P flag)
The Resync Flag should be used with the Ethernet Message flag. The host computer receives a
tag number message, processes the image and sends a pass/fail result (as an SN command) back
to the CC320. The CC320 matches the message to the original trigger and time the pass/fail
output pulse accurately.
If an SN command is not received in time, then the product is rejected, and an error code output.
6.2.4 FIFO Flag (F)
The FIFO flag is used for systems where there can be more than one product between the trigger
point and reject gate. This is usually used with the Resync flag, so that each product has its own
pass/fail result.
If the FIFO flag is not set, then an output cannot be re-triggered until the previous pulse has
completed. Others triggers in this time are ignored.
If the FIFO flag is set, then multiple triggers are stored in the CC320 and a pulse is generated for
each trigger at the correct time.
6.2.5 Pulse Flag (P)
The Pulse flag is used to select whether a pulse is needed to reject or to accept a product when
the Resync flag is set. When not set, a pulse is required to reject product. If a pass/fail message is
not received in Resync mode, the CC320 defaults to rejecting the product.
6.3 Examples
6.3.1 Sequenced Pulses
A sensor detects product presence. There are two cameras which need to take an image after
different delays. The leading edge of IP1 is used as the trigger. OP1 triggers the first camera after
100ms. OP2 triggers the second camera after 200ms. Both camera triggers are positive pulses.

2 2 1 0 200ms 100us 0 0
Both outputs are set into pulse mode. Two different delays give the timing difference between
the two cameras.
6.3.2 Gated Pulses
A camera needs to be triggered at 25Hz continuously, except when IP1 is high to indicate that the
machine has stopped. The camera is triggered on OP1.

OP1 will trigger continuously at 25Hz only when IP1 is low. Note that Flags = 4 to invert the
sense of IP1. If Flags = 0, then OP1 only trigger when IP1 is high.

6.3.3 Belt Position Triggering
On a conveyor with an encoder, a sensor detects product presence. There are two cameras which
need to take an image at fixed distances along the belt. The camera trigger pulses must be fixed
width for exposure control. The trailing edge of IP4 is used as the trigger. OP1 triggers the first
camera after 2000 encoder counts. OP2 triggers the second camera after 4000 encoder counts.
Both camera triggers are negative pulses.

Both outputs are set into pulse mode. The pulse delay is a number of encoder pulses and the
pulse width is a fixed time. The flags specify the trailing edge of the trigger signal and that the
output pulse is active low.
6.3.4 Pulse Burst
A sensor on IP1 detects product presence. Four images need to be taken from one camera using
four different lights at 40ms intervals. OP1, OP2, OP3, OP4 are used to output triggers to turn on
the four lights in sequence. OP5 is used to trigger the camera four times.

4 2 1 0 120ms 40ms 0 0
5 8 1 4 40ms 100us 0 0
OP1 to OP4 are pulsed for 40ms in sequence. As each one is pulsed, OP5 is also pulsed for a
short time to trigger the camera (Gate Input = 4 specifies four pulses).
6.3.5 Simple FIFO Mode
A sensor on IP1 detects product presence. After a delay OP1 triggers a camera. There may be
several products between the sensor and the camera.
The CC320 needs to store each of the triggers and then output a pulse after the correct delay.

6.3.6 Resync Mode
A sensor on IP1 detects product presence. After a delay OP1 triggers a camera. Image processing
software processes the image (which can take a variable length of time) and then sends a pass/fail
message to the CC320. The pass/fail is re-synchronised to the original product presence and the
reject gate is opened if necessary.
The reject gate is on OP2 and pulses high to reject the product. Products take 10 seconds to travel
from the sensor to the reject gate and take 1 second to move past the reject gate.

(104)
10 seconds after a trigger, OP2 is set to pulse for 1 second to reject a product.
The camera trigger has the “Send trigger message” flag set. So that the product is detected, a
message is send to the image processing software. The image processing software must use the
GT command to receive these messages.

The image processing has to send a pass/fail message before the reject gate is reached by the
product. As well as “Resync mode” the “default to pulse” flag is set. This means that if the image
processing software does not send a pass/fail message OP2 is pulsed anyway.
In this example, three product triggers were received. The camera was triggered using OP1.
An Ethernet message with tag number 10 was sent to the host computer when the first trigger
was received, but for some reason a reply was not received, so the product was rejected for fail-
safe operation. After the second trigger a Tag 11 message was sent, with the reply “SN2,11,1”
(OP2, tag 11, pass) so the reject pulse on OP2 was cancelled. After the third trigger a Tag 12
messages was sent, with the reply “SN2,12,0” (OP2, tag 12, fail) so the reject pulse on OP2 was
not cancelled.
6.3.7 Resync and FIFO Mode
This uses the same situation as the previous example, but products are 4 seconds apart, so that
when a product is detected, there are already two others travelling towards the reject gate.
Image processing software processes the image (which can take a variable length of time) and
then sends a pass/fail message to the CC320. The pass/fail is re-synchronised to the original
product presence and the reject gate is opened if necessary.
