Three parameters define a power supply connection: power supply selection, voltage, and warm-up time. The voltage
parameter defines the supply voltage. The warm-up parameter defines the time the power supply is on before evaluating
the input point.
Pulse Width (Outputs Only; bits 7:0). The number of 62.5 ms intervals a digital output is active (1) before returning to zero.
Zero disables the pulse width feature and any value on an output point remains indefinitely. Maximum pulse width is about
16 seconds. Value range: 0 (disable, default) through 255. (Parameter number 0x0A).
Report Rate (bits 15:0) . The report rate defines the rate that the I/O status is reported back to the Gateway. The value
represents the number of 62.5 ms increments. Report rates can be from 0 to 4095 seconds. A non-zero report rate
guarantees a report on a periodic basis AND at change of state. When set to zero, there will only be a report at change of
state. Value range: 0 through 65535. (Parameter number 0x04).
Report Type (bits 1:0). Defines the internal data structure and reporting definition for an I/O point. If a discrete point changes
state, all I/O points are reported to the Gateway in discrete values. An analog input can be treated as a digital value using
the Threshold and Hysteresis parameters. (Parameter number 0x0E).
• Discrete/bit report type = 0. Use for discrete values.
• Analog report type = 1 (default). Use for all analog values (two bytes).
• Double report type = 2. Use for 32-bit counter values (four bytes).
Samples High (bits 7:0). The number of samples an I/O point must be detected high (1) before it is a change of state. This
parameter can be applied to a discrete input or a analog input using the threshold parameter. Value range: 0 (disable,
default) through 255. (Parameter number 0x06).
Samples Low (bits 7:0). The number of samples an I/O point must be detected low (0) before it is a change of state. This
parameter can be applied to a discrete input or a analog input using the threshold parameter. Value range: 0 (disable,
default) through 255. (Parameter number 0x07).
Sample Rate (bits 15:0). The rate at which the I/O point is sampled. The value represents the number of 62.5 ms increments.
The sample rate/interval can be from 1 (0.0625 seconds, default) to 65535 (4095 seconds). Set to 0 to Sample on Demand.
(Parameter number 0x03).
Sample on Demand allows a host system to send a Modbus command to any register and require the Node's inputs to
immediately sample the sensor and report readings back to the host system. Sampling on demand can be used between
the normal periodic reporting.
Serial Address. The serial address parameter defines the remote serial device address to read. This parameter also defines
configuration information for the Extended Logic I/O type. (Parameter number 0x19).
Switch Power Voltage (bits 7:0). Used for I/O points supplying power to external devices. Use the lowest operating voltage
of the external device when supplying power from a battery-powered DX80. Value range: 0 (default) through 255.
(Parameter number 0x0B).

Threshold (bits 15:0). The trigger point or threshold for an analog input. When an analog input is greater than or equal to the
threshold value, a ON or 1 event is reported (if not inverted). If the analog input does not reach the active threshold value, no
change of state is reported. If the threshold parameter is 0, there is no threshold and the analog input will report based on
the delta rate. Value range: 0 (disable, default) through 65535 (two-byte value). (Parameter number 0x08).
Units (bits 7:0). The parameter defines the range and/or type of value associated with the I/O point. The devices use this
parameter to correctly interpret the I/O point data. (Parameter number 0x0C). (See units tables after this section.)
Warm-up Time (bits 7:0). Values 01 through 127 set the number of 62.5 millisecond increments. Values 129 through 255 set
the number of 250 microsecond increments, with 129 representing 250 microseconds, 130 representing two 250
microsecond increments (500 microseconds, and 255 representing 127 250 microsecond increments (or 31 milliseconds).
When the device supplies power to external sensors, this parameter defines how long power is applied before the input
point is examined for changes. When running multiple I/O point using switched power, only use values 0–127 (62.5 ms to
7.9 seconds). Value range: 00 (off, default) through 255. (Parameter number 0x05).
Internal Output Mapping. Reserved. Do not use. (Parameter number 0x1A).
Miscellaneous. Reserved. (Parameter number 0x17).
