IC687BEM713B使用说明,GE燃机卡件
查看第5.4.1节和表5.3-1，以验证所有工厂安装的跳线已就位。更改董事会地址或地址修改器响应，请参阅第5.4.2节。c、 输入电缆是否配有合适的配套连接器连接到输入连接器P3和P4？参考第5.6节有关连接器的说明。d、 校准已在工厂进行。如果重新校准应该需要时，请参阅第5.5.2节。e、 将未使用的输入（高压侧和低压侧）接地到VMEbus地注意安全请勿在系统通电的情况下安装或卸下此板。
IC687BEM713B使用说明5.4操作配置VMIVME-3112板地址和输入/输出访问模式的控制是由现场可更换的车载跳线决定。本节介绍了使用以及它们对跳投性能的影响。位置和所有VMIVME-3112跳线的功能如图5.4-1和表5.3-1所示。5.4.1工厂安装的跳线每个VMIVME-3112板在工厂配置有特定的跳线布置如表5.3-1所示。工厂配置建立VMIVME-3112板的以下功能基线，并确保所有安装了必要的跳线。
a、 电路板短地址设置为0000十六进制b、 输入/输出访问模式为短监督访问
c、 模拟输入范围设置为±10 V满标度范围d、 A/d扫描的通道数设置为64
e、 增益放大器设置为增益“1”电路板地址和地址修饰符选择跳线头J13允许VMIVME-3112板位短输入/输出地址空间内的任何256字节边界。短I/O地址空间由NNNN0000十六进制*和NNNNFFFF十六进制之间的所有地址组成，并要求对15（字）地址行进行解码，以说明所有*（NNNN）十六进制取决于CPU板。（85）十六进制是地址位A15到A08 as展示。（二十） 十六进制选择板载寄存器（见表4.1-1）。*短路=“零”（已安装跳线）Open=“一”（未安装跳线）（见表5.3-1）。AM2+AM2选择短监督访问、短非特权访问或两者兼有（即所示示例适用于短期非特权访问）。
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).
