Page 2: Getting Started
Read the sections on Safety and Specifications and check the PP420 fulfils your requirements. See the back cover for other Gardasoft Vision lighting controllers. Connect the PP420 up to a power supply, Ethernet network and lights as described in Connections. -

3.1.4 General The PP420 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... -
Page 4: General Description
Configurations are saved in non-volatile memory so that the PP420 will resume operation after a power cycle. The PP420 is set up using the push buttons and display on the front of the unit or using Ethernet commands. The set up is non-volatile, so the PP420 will resume the same operation after a power cycle. - Page 5 Where “c” is the output channel number. An application can send an RR command back in reply, which will cancel the user prompt. Once the PP420 has detected the light and has a current rating for it, the light will start its configured operating mode.

Page 6: Output Modes
4.3.2 Pulsed Output The output is off by default. When a trigger is the PP420 will wait for a delay and then pulse the output. The delay, pulse width and pulse intensity are all configurable. If the “P” flag is set triggers occur on the leading edge of the input, that is on the transition from 0V to (for example) 5V. -
Page 7: Current Protection
0.5ms So for example, if the brightness is set to 350%, then the PP420 will not allow pulses greater than 2ms long. If the trigger pulses are too close together so that the lights are on for more than 10% of the time, the PP420 will stop the output and flag an error. -

Page 9: Mechanical Fixing
Mechanical Fixing The PP420 can be mounted onto a flat surface using the mounting holes in the corners, see diagram. The PP420 should only be mounted either vertically or with its base horizontal. should be mounted at least 15mm away from the sides of plastic enclosures. Likewise leave a similar space between the PP420 and any parts which could be affected by high temperatures. -
Page 10: Heat Dissipation
If an enclosure is used, the enclosure should be metal or plastic (with a flammability rating of UL94 V1 or better); with no holes below or to the sides of the PP420 when mounted. Cable entries below the PP420 should be via glands that have a flammability rating as before. Observe the specified gap between the PP420 and any other part or side of the enclosure. - Page 11 If the heat output is no greater than 8W, then no heatsinking is required. If the heat output is between 10W and 24W then the PP420 needs to be bolted to a solid piece of metal to dissipate the heat. Above 24W, it is necessary to have a large heatsink with fan cooling.
- Page 12 LED4- supplementary insulation is used. TRIG1- The PP420 has a single power input Trigger input 1 connection (which is different from the TRIG1+ PP600). TRIG2- Power supplies should be regulated with Trigger input 2 SELV compliant outputs (fault tolerant).

Page 13: Ethernet Setup
0x00.0x0B.0x75.0x01.0xNN.0xNN. IP Address The PP420 needs an IP address to communicate over Ethernet. There are two ways to get an IP address; either programmed into the unit or using DHCP. Most networks use a DHCP server. If there is a PC on the network, You may be able to find out... - Page 14 DHCP server. Otherwise the PP420 has a fixed IP address, subnet mask and gateway address. DHCP mode or a fixed IP Address can be set up using the PP420 Configuration Program. This will work on any network, as the Configuration Program broadcasts the network setup message to the PP420.
- Page 15 An enquiry message is a UDP packet from source port 30310, destination port 30311 with the message body “Gardasoft Search” (8-bit ASCII, 13 characters). The message output by the PP420 is a UDP packet from source port 30311, destination port 30310. It is formatted as:...

Page 16: Webpage Configuration
The PP420 has a small webserver inside, so that it can be configured from a standard web browser, such as Internet Explorer. The IP address of the PP420 must be known (see the section on “Ethernet Setup.” Open a web browser window and type the IP address (for example 192.168.1.71) of the PP420 into the URL box at the top. -
Page 17: Ethernet Configuration
Several commands can be put into one command line by separating them by a semi-colon (“;”). A carriage return character should be sent to terminate the command line. The PP420 will send any replies to the commands and then send a ‘>’ character to indicate that the command line has been completed. -
Page 18: General Commands
For example: Parameter Meaning 0.1 milliseconds 200us 200 microseconds 0.1s 0.1 seconds 100ma 100mA 2.45A 2.45A 2300mA or 2.3A Note that parameters are in “USA/UK” format so that a half is written “0.5” not “0,5” The command codes and their meaning are described below. The upper case commands are shown, followed by lower case letters denoting the numeric argument. - Page 19 If Ethernet messages are not enabled, the last error number can be read by this command. Any error displayed on the unit is cleared, so if there was a lighting error, the PP420 will resume auto- sensing on that channel.
- Page 20 0 = Autosense (current rating needs to be entered on connection) bit 1 1 = No error detect 0 = Error detect. The PP420 continually monitors the output current and voltage bit 2 1 = Negative trigger. In pulse mode the trigger is the falling edge. In switched mode a low input turns the light on.

c = output channel (1, 2, 3, 4) s = setting in percent (s = 0 to 100) Set pulse mode The output can be set up to pulse on a trigger input. The delay from trigger to the start of the pulse, the length of the pulse and the brightness are configurable. - Page 22 Clear all settings, except Ethernet EY80,87 Set webpage password to “PW” RP2,3 Use trigger input 3 for Channel 2 RE1,3 Set channel 1 to ignore lighting errors and not prompt for the current rating of a light when it is connected.

Page 23: Switched Mode
A. Timing The following timings apply for firmware revision V011. A.1 Switched Mode The maximum delay from a trigger input changing to the output current being turned on or off is 10us. A.2 Pulse Mode For short delays and pulse widths the actual timings are repeatable but not exact. Timings are dependent on the output current as described in the two tables below. - Page 24 B. Events The PP420 can send out UDP or TCP messages on certain events. See the GT command to see how to enable/disable Ethernet messages. The messages are of the form: Evt c,m Where: c = output channel (1, 2, 3, 4) or 0 for general messages...
