Hardware Options and Installation

2.1 Hardware Overview

This chapter describes the basic procedure for installing the H-5223 including wiring for power,
sensors and communications. For proper installation you will need:

! The H-5223 mounting hardware
! Small flat blade screw driver
! Power and communication cables
! Sensors as needed.
! The H-5223 owner’s manual
! Sensor owners manuals.

2.2 Front Panel Connections

Figure 2-1 illustrates the physical location for the I/O of the H-5223. This diagram will help
show
where to connect the different sensors to the H-5223.

Figure 2-1 H-5223 Main I/O Panel

2.2.1 Earth Ground Lug

On the left side of the H-5223 is an earth ground lug. This provides a connection point for
grounding the unit to earth ground. If there is no earth ground at the site, one should be installed.

H-5223 Hardware Options and Installation 2-1

2.2.2 Com Port RS-232

This is the main RS-232 port for communicating to the H-5223. The RS-232 port is used to
connect to a PC, PDA, modem, or other type of serial equipment for standard serial
communications. This port is configured as a DCE type of device. This means it will plug
directly into a PC (a DTE type device), but will require a NULL modem adaptor for connecting
to most PDA’s or a modem (a DCE type device). The NULL modem cable crosses the
communication lines allowing two similar devices to communicate. Figure 2-2 shows the pin
assignments for this port.

Figure 2-2 Serial Port Pin Assignments

2.2.3 Analog Input Section

The first seven connections on the terminal block are used for analog input functions. This
includes four analog inputs, two analog grounds and one +5.00 volt excitation connection.

2-2 Hardware Options and Installation H-5223

2.2.3.1 Analog Input Channels

There are four analog input channels labeled Vin1 to Vin4. The input range is 0 to 5 volts DC
and the maximum input should not exceed 5.0 volts. Each input can be programmed with a slope
and an offset allowing the final value recorded for the input to be scaled to some units of measure
like temperature or wind direction. Programming the slope and offset will be discussed in detail
in chapter 3.

2.2.3.1.1 Differential Input Option

Channels 1 and 2 can be used together to form a single differential input channel. This option is
intended for bridge type of sensors like a strain gage. This type of sensor has two output signals
that are referenced to each other, not directly to ground. See figure 2.3.

Figure 2.3 Bridge Sensor

2.2.3.2 Analog Grounds

There are two analog ground connection points. In order to preserve signal integrity, it is
important to use the analog grounds only for sensors connected to the analog section of the
H-5223. The current flowing through an analog sensor is relatively small and normally very

stable. This provides stable voltages produced by these sensors. If a digital sensor has its ground
connection tied into the analog ground, the currents from the digital sensor will flow through the
analog circuitry causing voltage level shifts and noise based on digital switching. There should
be sufficient digital ground connection points for the digital sensors.

H-5223 Hardware Options and Installation 2-3

2.2.3.3 Switched +5.00 Volt Reference Excitation

The +5 Volt reference output is used for analog sensors requiring a precision reference voltage.
The output current source maximum level is 10 milliamps. Exceeding this limit will cause the
excitation to possibly sag, and result in possible data errors. The Analog to Digital converter uses
this excitation for its reference to provide a ratio-metric relationship for sensors using the
excitation. What this means is that if a sensor causes loading to the excitation and drags it down
to 4.75 volts for example, then the A/D converter will use the 4.75 volts as its reference, and
maintain a full scale input equal to the reduced excitation. To a point this will reduce errors in
data when the excitation is used. If the excitation is being loaded down and some analog input
channels are not using the excitation, but produce a voltage output on there own, then these
inputs will have a much greater error.

Figure 2-4 shows a simple resistive type of sensor that would be typical of a wind direction type
of sensor. On a wind direction sensor a change in direction caused a variable resistor to move
causing a change in output voltage that is proportional to the direction. In this example the +5Vx
is used to power the sensor.

Figure 2-4 Simple Resistive Sensor

2-4 Hardware Options and Installation H-5223

2.2.4 Digital I/O 1 and 2

Pins 9 and 10 of the terminal block provide connection points for the two digital I/O signals.
Notice pin 8 is a digital ground and is grouped with these two pins. When using the digital I/O’s
this ground pin should be used as the reference point. Do not use the analog grounds.
The two digital I/O signals can be configured independently as inputs or as outputs. In the input
mode, the signal has an internal pull up resistor of 51K Ohms. This allows a switch closure to
ground to activate the input. It can also be driven using 5.0 volt logic levels. As an output, the
drive capability is limited by a 100 Ohm protection resistor. The output will still be about 4.0
volts or higher with a 10.0 mA or less load. Transient protection is provided for this input to
prevent damage from static discharge or over voltage conditions. When both pins are configured
as inputs, they may be used as a quadrature shaft encoder input. Typical applications for these
digital I/O pins include tipping bucket counter inputs, on / off status inputs, output alarming,
triggering samplers, etc. Figure 2-3 shows a simplified schematic of how these pins are
configured.

H-5223 Hardware Options and Installation 2-5

2.2.5 SDI-12 Section

Pins 11, 12, and 13 of the terminal block provide connection points for SDI-12 senors. The
+12Vsw power connection under the SDI-12 section is limited to about one amp so it may be
necessary to connect the SDI-12 sensor power line directly to the battery or to main power. This
excitation can be set to stay on continuously or to be switched on only at scan time.

If this excitation is to be turned on and off at scan time, then it may be necessary to have a warm
up delay after the excitation has turned on before starting to take measurements. The warmup
delay can be in the range of 0 to 9999 milliseconds.

If several SDI-12 sensors are to be connected to the H-5223, it may be necessary to use external
terminal strips to provide enough connection points.

Figure 2-6 SDI-12 Expanded Connector System

2.2.6 Power Connections

The last two pins at the far right of the terminal block provide the main connection points for
system power and ground.

NOTE: If the battery voltage is below 11.0 volts the GOES transmissions will stop. If the

battery voltage is below 9.5 volts, data logging will stop.

NOTE: When connecting to or removing the wires from these connection points, it is important

to remove the terminal block from the H-5223 first, or to have the other end of the
wires disconnected from the battery.

NOTE: Make sure scanning is turned off on units not being used to help preserve backup

battery life.

2-6 Hardware Options and Installation H-5223

2.3 Top Panel Description

On the top of the H-5223 are antenna connectors, power connectors, host and auxiliary
connectors, GOES fail safe button, and LED indicators

2.3.1 GOES Antenna

This is the GOES RF antenna connector and is a male SMA type of connector. Most GOES RF
antenna cables have an N type of connector so an adaptor will be needed to go from the one
connector type to the other.

2.3.2 +12VDC / Ground

This is the primary power connection to supply power to the transmitter.

2.3.3 Fail Safe Button

This button is used to manually reset the failsafe when it is tripped. The button needs to be
pressed and held in for 3 seconds to reset the failsafe.

2.3.4 LED indicators

Failsafe: Blinks to indicate that the failsafe has been tripped.

RF On (Solid): When LED is continuously on this indicates that a transmission is in

progress.

RF On (Blinking): When LED is blinking this indicates the transmitter failsafe timer is

running.

GPS On (Solid): When this LED is continuously on this indicates that the GPS receiver is

fixed onto 3 or more satellites.

GPS On (Blinking): When LED is blinking this indicates that the GPS is trying to acquire a

GPS fix.

2.3.5 GPS Antenna

This is the GPS antenna connector. The GPS antenna should be mounted in clear view of the
sky.

H-5223 Hardware Options and Installation 2-7

NOTE: When power is first applied to the unit it will try to sync the GOES time clock causing

the current draw to be around 35 mA. Once the time sync is complete the current will
return to the normal low power state. If the antenna is not installed the system may
continually draw higher current.

2.3.5 Host and Aux Port (RS-232)

The host port is used to connect the transmitter to an external data logger. The Aux port is used
to debug and monitor the status of the transmitter.

2.4 Testing the Installation

With a PC connected to the system and running a terminal emulation program like Pro Comm or
Hyper term, then when hooking up the battery a power up message is displayed on the PC screen.
This indicates that the battery is providing the proper power to the H-5223, and that system
variables have been initialized.

You will find detailed user setup information and menu options that will allow complete test and
verification of all sensor connections and operation in the next two chapters.

Menu Mode Operation

3.1 Menu Mode Interface

All communications with the H-5223 are through a command interface or menu interface using
the main RS-232 Serial Port. The menu interface is the default mode of operation. If in the
command interface, entering the command “MENU” will cause the system to enter the menu
mode. The menu mode is used to display a menu on the screen allowing simple human access to
the system options. To access either the menu or the command interface, the H-5223 must be
connected to a computer that is running some type of terminal program. The terminal program
must use the same communication settings as used by the H-5223. The default communication
values of the H-5223 are shown below along with other related options.

All options available through the menu interface are also available using the command interface.
This chapter focuses on the menu interface only. When a computer is connected (direct
connection or modem connection), pressing the ENTER key will cause the main menu to be
displayed. It may take a second or two for the H-5223 to wake up and display the menu. If the
H-5223 seems slow pressing the ENTER key a few extra time will cause no problems. Once the
menu is displayed, the H-5223 is ready for interrogation. If no commands are received in a five
minute time period, the H-5223 will turn off automatically and return to a low power mode.

Each menu option is preceded with a letter or number that when pressed will activate the
indicated option. The ENTER key does not have to be pressed after an option key is pressed.
Some options will open a sub menu and others will allow the user to set or change a system
parameter. When in a sub menu, pressing the ESC key or the ‘B’ key will back up one menu. At
the main menu these keys will have no effect. Pressing the ENTER key or SPACE bar at any
time will refresh the current screen.

At the bottom of each menu screen is an “Ente r Opt i on > ” prompt. When an option key is

H-5223 Remote Operation (Menu Mode) 3-1

pressed that allows a system parameter to be changed, any additional information for that option
will be displayed after the prompt. There are two types of system parameter change options, first
is an option that requires direct keyboard input like a ‘Site Id’ or a column header label. The
second is an option that has a pick list of valid options such as an input source option. This type
of option allows the user to scroll through the valid options using UP and DOWN arrow keys.
Pressing the ENTER key will accept the displayed option. Pressing the ESC key will abort any
changes and restore the original selection.

3.2.1 PDA Operations

Knowing that PDA’s are often used in place of the PC, the menus have actually been designed to
be small so a PDA may be used easily with the system. In some cases the amount of information
in a single menu may be broken up into smaller segments to allow a proper fit on the PDA
screen. When M - More or N - Next is displayed this indicates there are more options that are
not displayed for that menu and pressing the ‘M’ or ‘N’ key will display the remaining part of the
menu. Also some PDA’s may use a hidden key approach for the ESC key so the ‘B’ key will
work like an ESC key when backing out of a menu. The ‘B’ key cannot be used to escape or
back out of an editing option as it may be valid for input. The ESC key still must be used to
escape out of an editing option.

PC’s still may be used with the H-5223 using a standard terminal emulation program. In this
case only a portion of the screen will be used.

This is a status screen that shows the current time. There is no option here to change the
time. To change the time use the ‘Configure System’ menu.

H-5223 Remote Operation (Menu Mode) 3-3

Date:

This is a status screen that shows the current date. There is no option here to change the
date. To change the date use the ‘Configure System’ menu.

Scanning:

This is a status screen that shows if scanning is on or off. To turn scanning on or off use
the ‘Scan Setup’ menu.

Next Scan:

This is a count down timer until the next scan.

GOES Mode:

This identifies the current GOES Mode of operation. If the GOES radio is not
functioning a N/A will be displayed. Normally the N/A would only be displayed if the
system is or was operating on a low battery. Remove power for a few seconds and then
reconnect it. Make sure the battery is charged properly.

Battery:

There are three battery voltages listed: current voltage, maximum voltage measured, and
minimum voltage measured. The minimum and maximum values are mainly listed for
diagnostic reasons. If the minimum voltage is too low it may indicate that the battery is
being undercharged. If the maximum battery reading is too high it may indicate a faulty
regulator. The system will work properly between 11.5 and 15 volts. If the battery drops
below 11.5 then the radio will stop transmitting, but logging will continue. If the battery
voltage drops below 10.0 volts then the system stops logging and enters a low power
mode waiting for the power to be restored. Once the battery voltage raises to a normal
level the system will start logging and transmitting again.

System Resets:

This value shows how many times the system has been reset. A system reset can be
caused by several conditions; a loss of power, a power glitch or surge, a watchdog timer
resetting the system are a few. Normally a user will make sure this value is reset to ‘0'
before leaving the site on a site visit, then on the next visit checking this value to see if
any resets have occurred between the last visit an the current visit.

Version:

This is the current firmware version used by the system. New firmware versions may be
downloaded from the manufactures web page and loaded into the system by the user.
After a new version is loaded it is best to see that the checksum test still passes.

R - Reset Batt & Resets:

This option resets the Max and Min Battery voltage values to the current battery voltage
and resets the number of system resets to zero. When servicing a gauge site, use this
option to reset the battery values to the current battery value and to reset the number of

3-4 Remote Operation (Menu Mode) H-5223

system resets to zero. On the next visit to the site, review the condition of the battery
since the last visit by looking at the max and min values and the number of system resets.
Ideally, the number of resets would still be zero and the max and min battery values
would be within a normal operating range. A low minimum battery voltage could indicate
a weak charging system, a battery that is too small for the site, or bad wiring, etc. A low
battery could also cause the system to reset. System resets normally indicate a problem
with the battery voltage being too low, bad wiring, or poor power connections. Lightening
and other external factors may also cause the system to reset. A high maximum battery
voltage could indicate that the regulator is bad and that it is passing all of the energy from
the solar panel to the system.

3.5 I - Sensor Input Options

The “Sensor Input Options” menu shows the current values of all the sensor inputs. Also sub­menus are available for changing the setup parameters of each input. The following table shows
what the “Sensor Input Options” screen looks like.

V - Digital I/O #1 = 1

This option displays the current value for the selected digital I/O. This option will act
differently based on the selected mode of operation for the I/O. Also in some modes (counter

H-5223 Remote Operation (Menu Mode) 3-5

input and encoder input) the value can be set to an initial starting point. Below is an
explanation of how this option works for each possible mode for the I/O pins.

Digital Input: This option is used as a status indicator showing the current state of the

digital I/O 1 pin. The value will always be a 1 or a 0. A 1 indicates the pin
is high or at approximately 5 volts, and a 0 indicates that it is low or at
approximately 0 volts. Trying to change the value while in this mode
using the ‘V’ option will have no affect. This pin is internally tied high so
with nothing connected it will show up as a 1.

Counter Input: This option is used to view the current counter value. The value may be

changed as needed by the user to set an initial offset using the ‘V’
command. This value is reset to 0.00 at power up.

Encoder Input: This option is used to view the current encoder value. The value may be

changed as needed by the user using the ‘V’ option.. This value is reset to

0.00 at power up.

On At Scan: This option will normally always indicate a 0, but the pin will be set high

or to 5 volts during the scan. At the end of the scan the pin will be set low
again or to 0.0 volts. During the scanning process the screen is not
updated so this will indicate 0 even during the scan when in actuality the
pin is at a high level. Trying to change the value for this mode will have
no affect.

Output Pulse: This option will normally always display a 0 as the screen is not updated

during the scan or when the output is tested, but the pin will be set high or
to 5.0 volts during the scan if the trigger condition is true. The pin will go
low again after the pulse / delay time has elapsed.

Output Cont.: This option will reflect the state the pin should be. For example if the pin

is to be driven high then the indicator will be a 1. If the output is to be
driven low then the indicator will be 0. There may be cases where the
output is loaded to a point it cannot go high or low. In this case the
indicator will show what the pin should be, but if the pin is measured with
a volt meter it may be at some other level.

A - I/O 1 Mode

This option is used to define if the digital I/O pin should be an input or an output. If the pin
is to be used as an input it may be used as a general purpose input, as a counter input, or as a
quadrature shaft encoder input in association with the other digital I/O pin. If the pin is to be
used as an output, the user may define it as a pulsed output, a continuous output, or turn on
automatically at the beginning of each scan. The different modes of operation for the digital
I/O’s are described below.

3-6 Remote Operation (Menu Mode) H-5223

Digital Input: General purpose input returns a 1 or a 0. Typical application is a gate

position, open or closed. This is the default mode.

Counter Input: The pin is used as a counter input. A falling edge (5 volts to 0 volts)

causes a counter to increment by the count / encoder inc value. Typical
application is a tipping bucket rain gauge.

Encoder Input: If both inputs are set to this mode then a standard quadrature shaft encoder

may be used for stage readings. Normally Phase A of the encoder would
be connected to digital I/O 1 and Phase B would be connected to digital
I/O 2. A ground wire is also connected between the encoder and the H-

5223. Each change of state of the encoder will cause the encoder value to
increment or decrement at a rate set by the count / encoder inc setting.

On At Scan: This is an output mode that will cause the pin to automatically turn on

(driven high) before each scan and turn off at the end of the scan. At the
beginning of the scan when this pin is driven high, the scanning process
will be delayed for a time period set by the ‘Pulse /Delay’ option. A
typical application is to turn on a pump during each scan.

Output Pulse: This output option is used to pulse or turn on the output for a duration set

by the ‘Pulse / Delay’ option if a user defined condition exists. This
output will be pulsed sometime during the scan process. The condition is
defined by using the ‘Trigger Source” option, the “Trigger Mode’ option
and the “Trigger Set Point” option as defined below. A typical application
is to trigger an automatic water sampler that requires a 1 second pulse to
start its process.

Output Cont. This output option is used to turn on the output continuously when a user

defined condition occurs and to stay on until the condition goes away. The
condition is defined by using the ‘Trigger Source” option, the “Trigger
Mode’ option and the “Trigger Set Point” option as defined below. A
typical application is to turn on a warning light when a water level is too
high. The condition will be evaluated on each scan.

NOTE: On output modes; the H-5223 checks to see if the digital output mode is set for

“Output Pulse” or “Output Cont.” automatically at the end of each scan if it is not
set as source for logging or for GOES. At this time the output is activated if
needed. If it is set as a source for logging or GOES then the user defined
condition is check at that point and the output set or cleared at that point in time,
not at the end of the scan.

D - Pulse Length / Warm Up Delay

This option is used to define a pulse length when the digital I/O is set for pulsed output mode
and is used to define a warm up delay when the digital I/O is set for “On At Scan” output
mode.

Pulsed Output Mode: As defined, the system checks the mode of the digital I/O and if it

H-5223 Remote Operation (Menu Mode) 3-7

is set for pulsed output mode and the trigger condition is true, then the output will be set
high for a duration based on this option. The range is from 1 to 9999 milliseconds.

On At Scan: At the beginning of each scan the system checks the mode of the digital
I/O and if it is set for ‘On At Scan’ then the digital I/O is set high and the system delays
before processing the scan for a duration based on this option. After the scan process is
complete the digital I/O will be turned off. An example application where this option
could used is for a motor that needs to be turned on at the beginning of each scan but
requires a delay of 2 seconds before the sensors are scanned. In this case, the warm up
delay would be set to 2000.

C - Count / Encoder Inc Value

When in Counter Mode, this is the value that will be added to the counter for each high to
low transition of the input. Also when in Encoder Input Mode, this is the value used for
counting up and down based on a change of the encoder.

S - Trigger Source

This option is used to select a data source to use to compare with the ‘Set Point’ to see if the
digital output should be set or not. For example, to set the output high if the battery voltage
is below 11.0 volts, the battery must be selected as the source, and the set point option set to

11.0 and the trigger mode set to ‘< Set Pt’. This reads as; “if the battery is less than 11.0
volts then set the output high, else set the output low”. The trigger source could be any of the
normal inputs such as analog inputs, a counter input, SDI-12, etc.

T - Trigger Mode

This option is used to select the type of condition to use to compare the trigger source and the
set point. The following show the valid options:

> Set Pt: Greater than set point. Set the output high if the source is greater than the

set point.

< Set Pt: Less than set point. Set the output high if the source is less than the set

point.

Always: Always set the output high regardless of the set point or source.

P - Trig Set Pt

This option is used to set the value the data source will be compared with to see if the digital
output should be set high or not.

1 - Test Dig 1 Output

When the digital I/O 1 pin is configured as an output, pressing the 1 key will activate the pin
for testing purposes. If the pin is configured for pulsed output, the output will turn on for the
defined pulse length and then turn off again. If the pin is configured for continuous operation,
