The module case also has a PC connector at the rear to accept an ad-ditional seven analog input channels for a total capacity of 32 chan-nels of analog input data.

Each module case contains an analog multiplexer and analog..:.to-digital converter. The mulitplexer samples each channel sequentially, and the analog-to-digital converter converts the analog signal into a serial digital word containing 12 bits of data (resolution of 1 part in 4096) for transmission over a balanced line or fiber optic cable.

Each module case has identification switches to set the link, sublink and last channel number. The data scan begins with a start word, an ID word, and up to 32 channel words. The setting of the last channel number switch determines the point at which the scan will start over again.

Several calibration voltages ~re also available which can be connected to spare analog input channels for automatic system calibration.

Each MC170AD module case is powered by a PS171 power supply which plugs into the module and for the purposes of the specification may be consi-dered part of the .module.

Height 5.-25 inches Depth 14.0 inches 4.2.4 Qualification Requirements None 4.. 3 MR.312 Master Receiver 4.3.1 Description The MR312 Master Receiver is capable of receiving serial data *directly from 16 MC170AD module cases, from 16 MX311 Digital Submultiplexers, or any combination thereof. The MR312 contains up to 16 plug~in DR317 Receiver cards. Each DR317 can receive 256 data words and store them in a RAM for controlled readout into a computer or *other peripheral equip-ment. The data words are contained in eight blocks with 32 words in each block. Each block is received with a start word and an ID word which identifies the link and sublink it was received from and how many words (channels) are in the block.

Each DR317 also has two sets of buffered output lines for feeding the received serial data to externai" devices such as a PCM tape recorder and DA313 Digital-to-Analog Converters in the MC314 Module Case. Serial data from.the PCM tape recorder may also be selected within the MR312 in place of a normal input from the MC170AD and/or*MX311.

The RAM on each receiver card is a part of the total MR312 memory. The 16 receiver cards can store one scan of all 4096 possible input channels.

Signals coming into the MR312 are stored_in memory, *and. any channel's data word may be retrieved on a parallel output bus by means of a paral-lel input address code bus. Two ways in which data stored in memory may be retrieved are:

New data can be allowed to overwrite old data such that the memory always has the most recent information.

Data can be held in memory until all data of interest on a given receiver link has been outputted. Then a signal on the memory-control lines can allow a new scan of data to overwrite the old stored data.

other.

The Master Receiver shall provide one PCM channel output to a magnetic tape recorder per link input to the Master Receiver.

The Master Receiver shall provide output data for up to 64 digital-to-analog converters.

Up to eight module cases containing a total of 64 digital-to-analog converters can be I

connected to the out~uts of the MR312 Master Receiver.

Each DA313 can be programmed to look at any input channel, and convert any one of the possible 4096 channel-word streams from the MR312 Master Receiver to an analog voltage of +10 to -10 volts, with data word rates up to 23,800 per second. The DA313 indicates if data is being received, and disp_lays the channel ID of the word being converted on a 5-digi t LED indicator. The selected channel may be changed manually with front panel push buttons or externally through computer control.

The +/-10 volt analog output signal can drive a pen recorder,

)

oscillograph recorder or an FM tape recorder. The signal operates a 2-channel alarm circuit to provide an alarm when input voltages are higher or lower than .

a preset level. A front panel high (HI) alarm and low (LO) alarm LED is .energized when the alarm in on.

Each DA313 has additional HI and LO alarm bus outputs. These are separately bussed in the module case. A HI alarm or a LO alarm on any channel in the module case can be detected by a single output.

The HI alarm bus and the LO alarm bus may be connected together or to busses on other MC314 module cases for a common output.

The DA313 also incorporates a variable gain and suppression amplifier with a four-position* gain switch for increasing gain from 1 to 10 in four increments. A gain potentiometer adjustment allow~ the gain to be changed from 40 to 110 percent of each gain range.* A second switch-controlled potentiometer allows any input from +lOV to -lOV to be suppressed to zero.
