Using CMOS Circuitry in Industrial Control

Using CMOS Circuitry in Industrial Control

Industrial computers originally used LSTTL circuits. Because many PC components are used in laptop computers, IC manufacturers are exclusively using CMOS technology. Both TTL and CMOS have failure mechanisms, but they are different. This section describes some of the common failures which are common to all manufacturers of CMOS equipment. However, much of the information has been put in the context of the Micro PC.

Octagon has developed a reliable database of customer-induced, field failures. The average MTBF of Micro PC cards exceeds 11 years, yet there are failures. Most failures have been identified as customer-induced, but there is a small percentage that cannot be identified. As expected, virtually all the failures occur when bringing up the first system. On subsequent systems, the failure rate drops dramatically.

- Approximately 20% of the returned cards are problem-free. These cards, typically, have the wrong jumper settings or the customer has problems with the software. This causes frustration for the customer and incurs a testing charge from Octagon.
- Of the remaining 80% of the cards, 90% of these cards fail due to customer misuse and accident. Customers often cannot pinpoint the cause of the misuse.
- Therefore, 72% of the returned cards are damaged through some type of misuse. Of the remaining 8%, Octagon is unable to determine the cause of the failure and repairs these cards at no charge if they are under warranty.

1.5″ Digital Ornament User’s Manual

This Digital Ornament is a stand-alone device that is designed to transfer and store images from a PC and then display the images. Using the application software supplied with this device, you can organize, edit, enhance and download the image in your PC to this device using a USB cable. The 1.5” Digital Ornament enables you to view 59 digital photos. Once you store the images into the Digital Frame, there’s no need to use a computer. You can enjoy your photos anytime and anywhere. It’s very convenient and quick. Battery operated, fully portable, Built-in Clock, USB connection for easy downloads.

Replacing the Batteries:
This pedometer uses two AAA size alkaline batteries (not included). Follow these steps to install batteries:
1. Press down on the back cover and slide the cover down and off the unit.
2. Remove the exhausted cells and insert two AAA size batteries as indicated by the polarity.
4. Replace the back cover.
Note: If the sound weakens, distorts, or the display dims, replace the batteries.

HUXSCOPE-UE Fiber Optic Microscope/Inspector User Manual

HUXSCOPE-UE Fiber Optic Microscope/Inspector User Manual

HUXSCOPE-UE TM is very usefully device to inspect ferrule in field. You can use it to inspect the connector installed inside hardware device and capture the image to your computer..
AVAIABLE APPLICATIONS
▪ Fiber Optic System / Sub-system with Fiber Networks
▪ Fiber Optic Module included Transceivers
▪ Test Equipment and Distribution Patch Panels
▪ Fiber Optic Components like Attenuators, Inside Adaptors

PRODUCT SETUP
1. Install first Hardware/Driver and then Software (refer to installation manual enclosed).
2. Connect Handset to Computer USB and Control the display size.
3. Cange Tip : The handset basically was assembled by SC/FC/PC Female Tip. If you want to change Tip to others, it could be changed by screw easily. Please keep clean lens in Handset when removing and changing the Tip. The lens is important to get clean images. So we recommend you should be careful.
4. Insert the tip into adaptor or female side of fiber optic devices. You can feel reaching edge of the adaptor. To get clean images, you have to rotate 360° FOCUS.
5. Capture Image to the computer.

Programmable Gain Amplifier PGA64 Operating Manual

Programmable Gain Amplifier PGA64 Operating Manual

The Multi Channel Systems device PGA64 amplifies analog signals with the option to change the gain. The input signal amplitude can be increased from a factor of 10 up to 5000. The gain is selectable by software and can be set for each of the 64 signal channels individually. The main parts consist of the analog filter stages, of a logic part to set the amplification, of an EEPROM to save the potentiometer settings, of a level converter accepting RS232 signals and of a power stage.

The signals of the 32 input channels are splitted to two different frequency bands. These bands filter the signals according to their frequency parts. The outputs are observable on the output connector. Examples of output signals are given. Two figures in the appendix demonstrate the dependance of the output signal amplitude from the frequency for the two used frequency bands.

Input signals are connected using a 68-pin SCSI connector. Output signals are transfered to other devices using a 68-pin SCSI connector, too. The pin layout of both connectors is given in a table. The digital signals to change the gain are delivered using a 9-pin SUB-D connector via the serial interface of a PC.

An internal power supply stage transforms the input voltages of any external power supply bin into the supply voltages of ±3.0 V and ±5.0 V. The supply bin should deliver raw voltages of ± 6.5 V at least, for connecting use 2 mm-connectors. The PGA64 uses a 3-pin LEMOSA connector as power supply input connector. The cable will be also delivered, too.
