本文概述了可同时控制几种不同类型焦平面阵列的电子多阵列控制系统的设计。该系统与SUBARU标准数据采集系统MESIA配合使用。MACS2和MESSIA实现了可见光和近红外波段的宽波长观测，需要不同类型的阵列。MACS2由四种类型的卡组成。一个成像系统需要一个隔离卡。一个阵列需要一个时钟驱动卡和一个ADC卡，一个ADC卡需要一个前置放大器卡。每一张卡片都是通过差分信号串联起来的。每个阵列不必放置得很近，即使控制多个阵列和类型也不需要更多的信号线。操作阵列的偏置电压和模拟输入端的偏置电压可以通过主机工作站进行控制和监测。我们可以安排各种环境来评估焦平面阵列，而无需修改印刷电路板或任何布线。MACS2对于计算不同类型的数组非常有用和强大。此外，我们还可以节省更换探测器损坏的备用卡的时间，并且使最近复杂的成像系统的维护变得更加容易。MACS2将安装在TRISPEC、两个InSb、WFCT和SIRIUS上。
This paper presents an overview of the electronics multi- array control system design that can control several different types of focal plane arrays simultaneously. This system is used with the SUBARU standard data acquisition system MESIA. MACS2 and MESSIA materialize a wide wavelength observation at visible and near IR wavelengths that requires different types of arrays. MACS2 consists of four types of cards. An isolation card is required for one imaging system. A clock driver card and an ADC card are required for an array, and a preamp card is required for an ADC card. Each card is daisy-chained through differential signals. Every array does not have to be placed closely, and no more signal lines are required even when controlling more than one array and type. The bias voltages to operate arrays and the offset voltage at the analog input can be controlled and monitored form a host workstation. We can arrange various environments to evaluate focal plane arrays without any modifications of printed circuit boards or any wiring. MACS2 is very useful and powerful for evaluating different types of arrays. Also we could save time to swap a spare card when a card for whichever detector is broken, and the maintenance of a recent complex imaging system becomes easier. MACS2 will be installed in TRISPEC, two InSb, WFCT, SIRIUS.
