FUNCTIONAL DESCRIPTION mm The A216E is a 34 1ength multifunction highspeed analogdigital IO card for ISAbus Computers and compatibles With this card installed the computer can t a precision data acquisition and control system or a signal analysis instrument A connections are made through standard 37pin D type connectors at the rear oft computer An additional 24 lines of digital lO are accessible through a 40 pin lD auxiliary connector that mounts on an adjacent mounting bracket ANALOG INPUTS The card accepts up to eight differential or sixteen single ended analog inputs Tl AME input configuration is switch selectable on the card providing a choice between 5 STAN singieAended channels or eight differential channels Analog inputs may be config 5 unipolar 0 10V or bipolar iSV and iIOV modes through the use ofjumpers i card These inputs are ampli ed by a low biascurrent fastesettling monolithic instrumentation amplifier with high commonmode rejection The ampli er provit 3TH programmable gains of 1 10 100 and 1000 and settles to 001 in 2 pSec The A1216E card uses a 12bit successive approximation analogtodigital come with a sample and hold amplifier input Under ideal

EXPANSION The card can be used with up to sixteen AIM16F analog input multiplexer cards 16 provides capability to connect sixteen differential inputs Thus when an A121I with a full complement of AIM1639s there can be as many as 256 analog inputs AIM716 with the A1216E requires a special cable adaptor ANALOG OUTPUTS The A1216E card has two 12bit digital tovanalog converters DA connected to independent and are selected by means of switches on the card The D 5 make oneboard reference voltage Analog outputs are disabled at powereup and remain until the computer writes to them This prevents spurious outputs from causing d when the system is first activated DIGITAL IO Four bits of Tl39LCMOS compatible digital input capability are provided Digital in and 1P2 have dual purposes Input IPO may be used to provide external start pul AD input 1P2 may be used as a gate input to CounterTimer 0 These inputs car converted to output ports for multiple AIM 16 applications as described under Int Expansion when this is done you give up capability for external triggering ofthe gating CounterTimer 0 Four bits of digital output are available with LS I TL logic levels and 10 LSTTL load capability Discrete outputs 0P0 through 0P3 provide multiplexer addressing cap input expansion use as described previously or can be used as separate digital c There are twentyfour bits of additional digital IO available on the auxiliary conn These bits are arranged in two 8bit ports and two 4 bit ports Each port may be independently programmed for input or output COUNTERTIMERS Three 16bit CounterTimers are provided on the A1216E CounterTimer 0 is en digital input and uses either an internal 1 0 MHz clock or an external clock of up This counter is not committed on the card Its clock enable and output lines are available at the IO connector CounterTimers 1 and 2 are concatenated to form countertimer for timed AD conversions andor external frequency generation T countertimer is enabled by program control and is clocked by a 1 Hz un board oscillator source CounterTimer 0 and CounterTimers l and 2 can be set up for counting frequency or period measurements and pulse or waveform generation PIN CONNECTIONS Connections are made to the A1216E card via a 37pin D type connector that ext through the back of the computer case The only differences between the A1216E AD121615F are the absence of
