New features in the 2008 edition:

4 Saved pages: create pages for titles, run time headers, anomalies etc - each page can have different fonts and text sizes. Pages are stored in non-volatile memory, so are maintained even after power off

4 Video channels: overlay text on up to 4 video signals - with the ability to apply different text to each signal - e.g. all signals could have time / date displayed, but 1st could also say "port Camera", 2nd would say "Centre Camera" etc

Serial string offsets: have problems controlling the positioning of your serial input strings ? You can now set X,Y offsets for serial strings coming in both port 1 and port 2

GPS input: want to plug in your GPS receiver and display your lat/long on screen ? Our system take any GGA compatible GPS serial string and display it on screen. With a GPS input, you can also sync the overlay's internal clock to the highly accurate time code being received from the GPS !

Captions: you can now set a short phrase or word caption to be displayed on each channel of video by default - regardless of the screen being cleared or power cycled. Typical examples are "PORT", "CENTRE", "STD" for pipeline surveys - or "Diver1" or "Aft Bell" in diver applications.

Field Upgradeable firmware updates: Keep your overlay bang up to date by downloading and installing the latest updates yourself in the field. If you have a special application, we can tailor custom firmware for you - email the update out and have you update the unit while on the vessel.

Analogue Input option: 4 channel, 12 bit ADC allows input and display of analogue input voltages with full protection / isolation on channel 1 for CP. The input voltages can be scaled, offset, prefixed and positioned independently on screen by using the menu system.

Free with every unit:

Units come with a software utility called 'Overlay Manager'. This software can be installed on any windows PC - which allows the user to interact with the Overlay very easily - save client specific setups, title pages and general headers .. (more)
