B-2 ADAM-5000

Data Formats and I/O Ranges

B.1 Analog Input Formats

The ADAM analog input modules can be configured to transmit data

to the host in Engineering Units.

Engineering Units

Data can be represented in Engineering Units by setting bits 0 and 1 of

the data format/checksum/integration time parameter to 0.

This format presents data in natural units, such as degrees, volts,

millivolts, and milliamps. The Engineering Units format is readily

parsed by the majority of computer languages because the total data

string length, including sign, digits and decimal point, does not exceed

seven characters.

The data format is a plus (+) or minus (-) sign, followed by five decimal

digits and a decimal point. The input range which is employed

determines the resolution, or the number of decimal places used, as

illustrated in the following table:

Input Range Resolution

±15 mV, ±50 mV 1 µV (three decimal places)

±100 mV, ±150 mV,

±500 mV

10 µV (two decimal places)

±1 V, ±2.5 V, ±5 V 100 µV (four decimal places)

±10 V 1 mV (three decimal places)

±20 mA 1 µA (three decimal places)

Type J and T

thermocouple

0.01ºC (two decimal places)

Type K, E, R, S, and B

thermocouple

0.1ºC (one decimal place)
