Page 3: Getting Started
VTR1 fulfils your requirements. See the back cover for other Gardasoft Vision strobe lights. Mount the VTR1 as described in Section 4. Connect the VTR1 up to a supply as described in Connections (Section 5). Set up the VTR1 for the desired operation as described in Configuration Commands (Section 9). - Page 4 Heat The VTR1 can dissipate up to 5W. It should be positioned away from flammable materials. Read the section on “Mounting the VTR1 (Section 5). Do not exceed the power ratings given in the manual. Electrical The internal circuit exceeds 46.7V but should not exceed 60V. Pulse peak voltages above 46.7V are considered hazardous.

Page 7: Power Supply
Connections See the Specification (Appendix A) for information on connection ratings. Assembled cables are available from Gardasoft Vision to the customer’s specification. All connections are provided on a 10 core cable. The wire allocation depends on the options provided. Ethernet... - Page 8 Low voltage and mains wiring should be routed separately. If they must be loomed together ensure that low voltage insulation rating is sufficient or that supplementary insulation is used. Power supply cable length is recommended not to exceed 3m. If longer cables are fitted, or if surge or transient interference greater than +/-60V may occur on the power supply lines, additional surge protection should be provided.

Page 10: General Description
51% to 100% So for example, if the brightness is set to 40%, then a VTR1-850 will not allow pulses greater than 3ms long. With 1ms pulses, if a trigger occurs within 33ms of a previous trigger (so that the duty cycle would be greater than 3%) the trigger is ignored. -
Page 11: Switched Output
7.1.2 Pulsed Output The output is off by default. When the VTR1 is triggered it will wait for a delay and then pulse the output. Retrigger delay is the minimum allowed time from one trigger to the next. Any triggers that happen too soon after the previous trigger are ignored. -
Page 12: Factory Settings
The default VTR1 configuration for the light output and trigger output are: Pulse operation • 1ms pulse width • 0.01ms delay • 50% intensity • 30ms retrigger delay • The CL command can be used to restore the VTR1 to its default configuration. - Page 13 Ethernet set up is not affected by cold booting the VTR1. Connection The Ethernet link uses a 10 base-T connection on an RJ45 connector. Typically the VTR1 will be connected to a network switch (or hub or router) although it is possible to connect it directly into the network port on a PC by using a suitable crossover cable.

Page 15: Webpage Configuration
Webpage Configuration This applies to the Ethernet version only. The VTR1 has a webserver inside, so that it can be configured from a standard web browser, such as Internet Explorer. The IP address of the VTR1 must be known (see section 7 on Ethernet Address. Open a web browser window and type the IP address (for example 192.168.1.71) of the VTR1 into the URL... -
Page 16: Configuration Commands
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 VTR1 will send any replies to the commands and then send a ‘>’ character to indicate that the command line has been completed. - Page 17 Any changes made using Ethernet commands are not saved permanently until the AW command has been issued. 10.3.1 General Commands Reports the version of firmware running in the VTR1 This command returns the firmware version. For example: VTR1 (HW001) V001 Set switched mode The output is set to switched mode at a percentage of full brightness.
- Page 18 Set the Option Flags RE1,p Where: p = 0 P flag set (positive triggers) p = 4 P flag cleared (negative triggers) Set Internal Trigger Enables or disables the internal trigger. When enabled, all outputs are triggered simultaneously using an internal trigger signal. This setting can be saved to non-volatile memory using the AW command.
- Page 19 If Ethernet messages are not enabled, the last event or error number can be read by this command. If there was a lighting error, the VTR1 will resume operation. The reply will be in the same form as the GT command above. If there are no outstanding events or errors, then only the prompt “>”...

- Page 22 B. Restrictions The minimum pulse delay for the light pulse output is about 2us. When using the retrigger delay, the minimum delay is around 5us. For pulse widths less than approximately 100us fault detection does not operate.

Page 23: Error Codes
Err 27 Can’t read Ethernet settings from EEPROM, so these may be incorrect. Err 33 The VTR1 is too hot. The VTR1 has a thermal cut-out that operates at about c to 70 c, depending on conditions. Any other errors are internal errors. - Page 24 Gardasoft Traffic Strobe Lights The products available at the time of writing include the following. Other products are also available.
