未使用的电路板应存放在他们是被运来的。当木板放在长凳上时对于配置等，建议使用导电材料插入电路板下方，以提供导电材料插入电路板下方，以提供导电分流器。收到后，在运输集装箱内发现的任何预防措施应观察。所有物品应仔细打开包装，并彻底检查装运期间可能发生的损坏。董事会应检查有无损坏的部件、损坏的电路板、热损坏和其他可见污染。因运输损坏引起的所有索赔应提交给承运人，并向VMIC发送一份完整报告，同时请求关于受损物品处置的建议。5.2物理安装注意安全通电时不要安装或拆卸电路板。断开设备电源，将电路板插入适当的插槽机箱的。同时确保电路板在支撑卡引导，使电路板平稳向前滑动，使其紧靠配对接头直至牢固就位。5.3通电前：检查表在VMEbus系统中安装电路板之前，请检查以下内容确保电路板为预期应用做好准备的项目。a、 有与理论和编程相关的章节，第3节是否已审查并应用于系统需求？
PROGRAM EXAMPLE
The following programming example demonstrates how to program most
of the A/D operating modes. Refer to the program outline for a description of each
programming module. program outline
* I. Leave autoscan mode.
* II. Initialize on-board timer for part IV.
* III. SCANNING POLL MODE + EXTERNAL TRIGGER example
* Set up a scan which is started by an external trigger.
* The end will be determined by reading a 3112 status bit.
* IV. SCANNING INTERRUPT MODE + ON-BOARD TIMER example
* Set up a scan which is started by the on-board timer.
* The end will be signaled by an interrupt.
* V. RANDOM POLL MODE example
* Do 64 conversions using the random access/poll mode.
* VI. Put the board back in autoscan mode. II. Initialize on-board timer for part IV.
*If the timer was shut off abruptly (before output strobe returns high) it
* can prevent external trigger operation until the timer is re-initialized.
* The time the strobe takes is equal to the period of the second-to-last
* counter if 2 or 3 are cascaded. For the example here, it is 1 millisecond.
*This sets up the timer for a 1 second delay. Jumper J7-2 should be connected
* to J8-2 by a shunt. The rest of J7 and J8 should not have shunts. The timer
* is an Intel 8254UNPACKING PROCEDURES
CAUTION
SOME OF THE COMPONENTS ASSEMBLED ON VMIC's PRODUCTS MAY BE
SENSITIVE TO ELECTROSTATIC DISCHARGE AND DAMAGE MAY OCCUR ON
BOARDS THAT ARE SUBJECTED TO A HIGH ENERGY ELECTROSTATIC FIELD.
UNUSED BOARDS SHOULD BE STORED IN THE SAME PROTECTIVE BOXES IN
WHICH THEY WERE SHIPPED. WHEN THE BOARD IS TO BE LAID ON A BENCH
FOR CONFIGURING, ETC., IT IS SUGGESTED THAT CONDUCTIVE MATERIAL BE
INSERTED UNDER THE BOARD TO PROVIDE THAT CONDUCTIVE MATERIAL BE
INSERTED UNDER THE BOARD TO PROVIDE A CONDUCTIVE SHUNT.
Upon receipt, any precautions found in the shipping container should be
observed. All items should be carefully unpacked and thoroughly inspected for
damage that might have occurred during shipment. The board (s) should be
checked for broken components, damaged circuit board(s), heat damage, and
other visible contamination. All claims arising from shipping damage should be
filed with the carrier and a complete report sent to VMIC together with a request for
advice about the disposition of the damaged item(s).
5.2 PHYSICAL INSTALLATION
CAUTION
DO NOT INSTALL OR REMOVE BOARDS WHILE POWER IS APPLIED.
De-energize the equipment and insert the board into an appropriate slot
of the chassis. While ensuring that the board is properly aligned and oriented in
the supporting card guides, slide the board smoothly forward against the mating
connector until firmly seated.
5.3 BEFORE APPLYING POWER: CHECKLIST
Before installing the board in a VMEbus system, check the following
items to ensure that the board is ready for the intended application.
a. Have the sections pertaining to theory and programming, Sections 3
and 4, been reviewed and applied to system requirements?
