5 CHANNEL MODE, PROGRAMMABLE FILTER, AND OUTPUT DEFAULT
CONFIGURATION
The network supplies configuration information to the HE550MIX577 in the Consumed Directed Digital
Data Words sent to the HE550MIX577. In the first word, the low 12 bits, 1 through 12, are channel mode
bits. A low mode bit selects ±10V and a high mode bit selects ±20mA. The next three bits, 13 through
15, are input digital filter time constant codes and the high bit, 16, is an adaptive filter enable bit. In the
second word, the low 12 bits are channel scale bits. A low scale bit selects ±10V or ±20mA for the
corresponding channel. A high scale bit selects ±5V or 4-20mA. The upper four bits are unused.

Each analog input on the HE550MIX577 has a single pole 345Hz (461uS) cutoff high frequency noise
filter. In addition a second digital filter may be specified in the first configuration word with the following
time constants.
This digital filter is useful for applications with significant amounts of random noise. The slower time
constants, while yielding better noise suppression, take a longer time to settle after step changes and are
also sensitive to impulse noise which is treated like Gaussian noise and averaged.
Bit 16 of the first configuration word may be set to specify an adaptive filter algorithm that:
1. Responds much more quickly to large step changes at slower time constants with full filtering of low
level noise.
2. Suppresses impulse noise at the expense of slightly slower response at the shortest time constant
settings. (Approximately 10 additional milliseconds)
Note that actual system response time is network dependent.

Bits 9 through 12 of the 5th configuration word control the behavior of the analog outputs when network
communication is lost. The bit to channel correspondence is the same as for the mode and scale bits. If
the corresponding bit is set, the outputs hold the last state. If the corresponding bit is cleared, the outputs
are set to the respective value supplied to the HE550MIX577 in the second four words of the Consumed
Directed Analog Data sent by the OCS. The other bits of the 5th configuration word are unused.
Refer to SmartStix Analog Programming Guide.
6 INPUT AND OUTPUT CONVERSION FACTORS
The following table describes how real-world values are scaled in the controller. For a given physical
voltage or current, the register data value may be calculated by using the conversion factor from the
table. The following formula is used: Data = Voltage or Current / Conversion Factor
Example:The user selects a voltage range of ±10V:
1. The physical voltage is 6 Volts.
2. Using the table, the conversion factor for the voltage range of ±10V is .0003125.
3. To determine the data value, the formula is used: Data = V / Conversion Factor
19200 = 6 VDC / 0.0003125
4. For the 4 to 20mA range, the offset, 4mA, must first be subtracted from the physical output value
before dividing by the scale factor to yield the register data value.

CsCAN Network IDs are set using the hexadecimal number system from 01 to FD. The decimal
equivalent is 1-253. Refer to following Conversion Table, which shows the decimal equivalent of
hexadecimal numbers. Set a unique Network ID by inserting a small Phillips screwdriver into the two
identical switches.

8 LEDS
SmartStix I/O Modules provide diagnostic and status LED indicators.
a. Diagnostic LED Indicators
Diagnostic LED State Meaning
Solid Red Initializing
MS
(Module Status)
NS
(Network Status)
Blinking Red I/O test failed, internal hardware fault
Blinking Green Module is in power-up state *
Solid Green Module is running normally
Solid Red Network Ack or Dup ID test failed **
Blinking Red Network ID test failed: ID not in the range of 1..253
Blinking Green Life Expectancy timeout, outputs are in default state ***
Solid Green Network is running normally
* If a blinking green Module Status persists for more than a few seconds the module has not received the
expected configuration from the OCS. This may be due to no Network I/O configuration created in
Cscape, not having downloaded the Network I/O configuration to the master OCS, an unpowered master
OCS, or the wrong Network ID number set on the module’s rotary switches.
** Network Ack means that no other node is active on the network. Dup ID test failed means that
another node with the same ID switch setting is already on the network.
*** Life Expectancy timeout means that the module has not received a periodic message from the master
OCS in the time specified in either the Life Expectancy directed data message or the Comm timeout of
the Network I/O Configuration window in Cscape.
b. Status LED Indicators
The Power Status LED illuminates Red when power is applied to the module. There are I/O Status LED
indicators for each of the Digital I/O points, which illuminate Red when an I/O point is ON.

10 INSTALLATION / SAFETY
When found on the product, the following symbols specify:
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of
fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
loss of life.
For detailed installation and a handy checklist
clearances, refer to the hardware manual of the controller you are using. (See the Additional References section in this document.)
• All applicable codes and standards need to be followed in the installation of this product.

Adhere to the following safety precautions whenever any type of connection is made to the module.
• Connect the green safety (earth) ground first before making any other connections.
• When connecting to electric circuits or pulse-initiating equipment, open their related breakers. Do
make connections to live power lines.
not
• Make connections to the module first; then connect to the circuit to be monitored.
• Route power wires in a safe manner in accordance with good practice and local codes.
• Wear proper personal protective equipment including safety glasses and insulated gloves when
making connections to power circuits.
• Ensure hands, shoes, and floor are dry before making any connection to a power line.
• Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits
are de-energized before making connections.
• Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.
