Customer Product Reviews
Dear Sirs
For the past 18 months I have made an average of two to three online purchases every week from a large number of suppliers and I am writing
to say that your Company has provided the most efficient service I have ever
received.
The order was placed in the early hours of Friday morning on July 4th with the item scheduled for delivery by 9.30 am on Saturday July 5th. The
delivery company Interlink Express fulfilled their commitment and the PCIboard that you supplied was installed by 9.35 am.
It was a delight to do business with your Company.
Thank you.

Texamatic
I use the Texamatic unit on my narrow boat, it is fantastic.
At the moment it is connected to my central heating. I text it half an hour
before I reach the boat and when I get there it is nice and warm. Although there
is a timer I don't always know when I will be there. It is so versatile. It
is possible to set a duration time. Mine is set to one hour. There is a spare
relay if I want it (shame it is not practical to operate the kettle). The sms
text alerts will be wired into the. Burglar alarm. Fire carbon monoxide alarm.
Water in the bilge alarm. Low temperature alarm (I am not sure what to set it to
yet). I would defiantly recommend it to anyone with a good boat and it would be
a good idea in a new boat.

NetCom Network to Serial Converter

The product rating 5+ |
 |
Simple to follow instructions and deployment was very easy and stress free. |
 |
The unit is an interface from various IP based wall panels used to control a single Audio mixer Cloud DC-1. |
 |
Works every time. |
 |
A very important point that should be included is your “outstanding” customer service and
support!! |

The OS900, and the octopus cable that shipped with it, are excellent items of kit. |
 |
The OS900 runs famously on both OS/2 Warp 4.0 and eComstation 2.0 RC5 in the 133MHz 64bit PCI-X slot of an IBM X345 rackmount server. I used the COM16.EXE driver as found at
http://www.os2site.com/sw/drivers/serial/index.html and the card was instantly recognised as COM2 through 9, all shared on IRQ3.
I'm driving Dataforth DCP485 DIN-rail mounted RS232-RS485 line drivers and the OS900 is handling the RTS direction control timing perfectly. |
 |
Roalan's support has been nothing short of brilliant, you said it would work and it does. There aren't many suppliers who will vouch for their modern equipment working on a legacy OS/2 platform in 2010! |

5 out of 5 from us here at the bottom of the globe in New Zealand. |

USB to Serial Converters
 |
The USB COM Pro and their lower cost manual set counterpart rate 5/5 as they just work on everything without fuss. |
 |
I am typically using them via virtualbox emulated windoze applications on a
Linux host in an industrial setting for PLC/HMI/Hardware applications. |
 |
The ftdi chipset is well supported under Linux and the
Linux/virtualbox emulation is flawless. |
 |
To date I have yet to find hardware it does not work on. |
 |
I have in the past trailed a huge number of different brands/models of
USB to serial converters and all have failed on various hardware combinations. This appears to be common trend amongst others in the field I talk too, all of which run windoze natively on their laptops.
Hence it is now very nice to have a converter that just works. |
 |
The only improvement I could think of, would be to have a version that knocks around in a bag better. I currently grind the din rail mounts off the single port versions that knock about in the bag. for permanent fixtures the DIN is perfect. I also commonly use the 2 port USB-2COM Pro and it works equally
well.

GSM-AUTO
 |
The star rating for this product is 5 excellent, we found the unit to be exactly
what we required and is easy to install. |
 |
The setting up is a bit complicated but achievable. |
 |
We use the product to switch our car park lighting on and off when we have events on outside our normal working hours. |
 |
But an excellent product and we will be purchasing more for other sites. |

Hi Roger
You will be very pleased to know that, despite our last telephone conversation, the GSM-AUTO IS working fine and has performed and behaved itself over the last weekend. Using the controller to work 2 20 amp contactors has worked fine. And I am now going try to get it to switch 2 controllers wired together (so I can get 4 heaters working if required).
Thanks for you help, patience and service
Regards
Andrew

BT232
I just wanted to congratulate you on the design of such a
marvelous product as the BT232P Serial Bluetooth Pair. The package arrived in very good time by a courier that actually pays attention to the customers comments and was very helpful! The dongles came with everything needed to set them up and the instructions were short, precise and easy to understand. Even the
Bluetooth dongles themselves provided assistance while I was configuring them! But the price is the biggest advantage. I did some shopping around and found that others were asking the same price for 1 dongle as you asked for the pair! And for such a full featured
ingenious design I feel like I got them from the best place! Within about half an hour my small robot was running about the floor completely
independent of the computer!
Brilliant delivery, brilliant product, brilliant company.
Stephen Timbers
Item [BT232] arrived safe and sound today the
22nd December 2004, far quicker
than I had ever expected from the other side of
the world - already in
and working, very easy to configure!
An efficient service which will be recommended
locally.
Thank you
Regards
