A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Quatech QS-100D, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Quatech QS-100D one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.

Unfortunately, only a few customers devote their time to read an instruction of Quatech QS-100D. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of Quatech QS-100D should contain:
- informations concerning technical data of Quatech QS-100D
- name of the manufacturer and a year of construction of the Quatech QS-100D item
- rules of operation, control and maintenance of the Quatech QS-100D item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Quatech QS-100D alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Quatech QS-100D, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Quatech service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of Quatech QS-100D.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Quatech QS-100D item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

    2.1 Setting the Base Address The base address of the QS-100D is set using the two DIP switch packs. When setting the address selection switches, a switch in the "ON" position specifies that the corresponding address line must be a logic 0 for the port to be selected. Similarly, a switch in the "OFF" position forces the correspon[...]

    2.2 Setting the Interrupt Level (IRQ) The QS-100D allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper pack J6. (Early versions of the QS-100D are limited to IRQ2-7.) In Figure 6 , the factory default setting of IRQ3 is shown. To select a different IRQ, move the jumper to the approp[...]

    The QS-100D signals a hardware interrupt when any port requires service. The interrupt signal is maintained until no port requires service. Because the ISA bus is edge-sensitive, this behavior forces the interrupt service routine to ensure that all ports are checked before exiting. A way to do this is to poll each port until an interrupting port is[...]
