Gardasoft Products and Engineering

June 2018

My trip to Asia was exhausting but very valuable. I visited customers in four countries in 12 days. So that I can spend as much time as possible talking to customers, I try to take evening flights after meetings during the day. Then I'm ready in a new city for more meetings at 9am the next morning. This worked very well, except for two times when I didn't arrive at my hotel until 3am!

The technical team at Gardasoft love meeting customers, finding out about their systems and working out how we can best help them. This isn't just about selling lighting controllers; it's about finding solutions to improve performance and reliability. We often provide custom features to make sure the customer gets exactly what they need. My colleague Doug Bourne is currently in the US on a two-week mission to visit as many customers as possible.

If you would like a phone call or visit to explore how our products can improve the performance of your systems, please send a request through the button at the bottom.

CC320 New Functions

We have added some new functions in the latest v026 firmware for our CC320 timing controller. These modes extend the range of solutions that the CC320 can address.

Mode 13 Triggered Counter (Cou)
This is a counter which outputs a pulse after a number of input pulses. The start of the count is triggered by another input.

Mode 14 Minimum Pulse Trigger (iPF)
Mode 15 Maximum Pulse Trigger (APF)
These functions ignore trigger pulses less or (or greater than) a certain pulse width. We used this on one of our exhibition demos to locate the index of a turntable, while generating trigger pulses on the same sensor.

Mode 16 D-Type Flip Flop (dLA)
Mode 17 Edge Triggered RS Latch (rLA)
Like traditional TTL latches, which can be used to remember previous triggers.

We can send a full description of these modes in release notes if you request it below.

APP959 Using an Oscilloscope

APP959 Using an Oscilloscope

For customers who have an oscilloscope available, APP959 Using an Oscilloscope describes how it can be used to check the timing of lighting pulses. Lighting pulses are generally viewed by probing LED and looking for a negative going pulse. It's important not to put the ground connection on LED¯.

When viewing the pulse shape as a voltage, the pulse looks a strange shape, which is misleading as the actual current pulse and lighting output are much squarer than this.

An oscilloscope is my favourite piece of test equipment. We ensure we have at least one per engineer in our development lab as we use them extensively.
