a、 電路板短地址設(shè)置為0000十六進(jìn)制b、 輸入/輸出訪問模式為短監(jiān)督訪問
c、 模擬輸入范圍設(shè)置為±10 V滿標(biāo)度范圍d、 A/d掃描的通道數(shù)設(shè)置為64
e、 增益放大器設(shè)置為增益“1”電路板地址和地址修飾符選擇跳線頭J13允許VMIVME-3112板位短輸入/輸出地址空間內(nèi)的任何256字節(jié)邊界。短I/O地址空間由NNNN0000十六進(jìn)制*和NNNNFFFF十六進(jìn)制之間的所有地址組成，并要求對(duì)15（字）地址行進(jìn)行解碼，以說明所有*（NNNN）十六進(jìn)制取決于CPU板。（85）十六進(jìn)制是地址位A15到A08 as展示。（二十） 十六進(jìn)制選擇板載寄存器（見表4.1-1）。*短路=“零”（已安裝跳線）Open=“一”（未安裝跳線）（見表5.3-1）。AM2+AM2選擇短監(jiān)督訪問、短非特權(quán)訪問或兩者兼有（即所示示例適用于短期非特權(quán)訪問）。
Review Section 5.4.1 and Table 5.3-1 to verify that all factory-installed
jumpers are in place. To change the board address or address
modifier response, refer to Section 5.4.2.
c. Have the input cables, with the proper mating connectors, been
connected to the input connectors P3 and P4? Refer to Section 5.6
for a description of the connector.
d. Calibration has been performed at the factory. If recalibration should
be required, refer to Section 5.5.2.
e. Ground unused inputs (both high side and low side) to VMEbus
ground.
CAUTION
DO NOT INSTALL OR REMOVE THIS BOARD WITH POWER APPLIED TO THE SYSTEM.
5.4 OPERATIONAL CONFIGURATION
Control of the VMIVME-3112 Board address and I/O access mode are
determined by field replaceable, on-board jumpers. This section describes the use
of these jumpers, and their effects on board performance. The locations and
functions of all VMIVME-3112 jumpers are shown in Figure 5.4-1 and Table 5.3-1.
5.4.1 Factory Installed Jumpers
Each VMIVME-3112 Board is configured at the factory with the specific
jumper arrangement shown in Table 5.3-1. The factory configuration establishes
the following functional baseline for the VMIVME-3112 Board, and ensures that all
essential jumpers are installed.
a. Board short address is set at 0000 HEX
b. I/O access mode is short supervisory access
c. Analog input range is set to ±10 V full scale range
d. The number of channels for an A/D Scan is set to 64
e. The gain amplifier is set to a gain of "one"
Board Address and Address Modifier Selection
Jumper header J13 permits the VMIVME-3112 Board to be located on
any 256-byte boundary within the short I/O address space. The short I/O address
space consists of all addresses between NNNN0000 HEX* and NNNNFFFF HEX,
and requires that 15 (word) address lines be decoded in order to account for all *(NNNN) HEX is CPU board dependent. (85) HEX is address bits A15 through A08 as
shown. (XX) HEX selects on-board registers (see Table 4.1-1).
**Shorted = "zero" (jumper installed)
Open = "one" (jumper not installed) (see Table 5.3-1).
***AM2 + AM2 select short supervisory access, short nonprivileged access, or both (the
example shown is for short nonprivileged access).
