System Connector –Pin Descriptions (Detailed)
Pin A +28 VDC Main Power In
This is the main power supply to the ISAT-100. The operating range is 22 - 30VDC
(18 – 30VDC for emergency operation).
Pin B - Ground (Power)
This is the power ground connection for the ISAT-100.
Pin C - Battery Disconnect
Connect pin C to pin B or ground to enable the ISAT-100’s internal battery. This
feature allows the ISAT-100 with the connector removed to be placed in storage for
several months without completely draining the internal battery, which could
otherwise result in damage.
Pin D - Analog Input #1
An analog voltage level between 0 and +30 volts, when applied to pin D, will be
converted to a digital value with 12 bits of resolution.
Pin E - Analog Input #2
An analog voltage level between 0 and +30 volts, when applied to pin E, will be
converted to a digital value with 12 bits of resolution.
Pin F - Analog Input #3
An analog voltage level between 0 and +30 volts, when applied to pin F, will be
converted to a digital value with 12 bits of resolution.
Pin G - Analog Input #4
An analog voltage level between 0 and +30 volts, when applied to pin G, will be
converted to a digital value with 12 bits of resolution.
Pin H - Analog Input #5
An analog voltage level between 0 and +30 volts, when applied to pin H, will be
converted to a digital value with 12 bits of resolution.
Pin J - Digital Input #1 – Voltage Seeking - (Mission)
A positive input between 5V and 28V, when applied to pin J, will produce a digital
logic high.
Pin K - Digital Input #2 - Voltage Seeking
A positive input between 5V and 28V, when applied to pin K, will produce a digital
logic high.
Pin L - Digital Input #3 - Ground Seeking
A ground input when applied to pin L, will produce a digital logic high.
