RCI-800 Connections:
The RCI-800 is the main board of an RCI-800-XXX Telemetry system. It provides the input and output
signal connections as well as the power supply for the unit. The RCI-800 consists of two circuit boards:
a main controller board with eight contact inputs and eight contact outputs and below it an analog
input/output board with eight analog inputs and eight analog outputs. A separate communications
board is added to the RCI-800 to allow it to communicate with other units. This communications board
may have its own configuration that is in a separate section of this manual. The following configuration
applies only to the RCI-800 board and is common to all communications interfaces.
AC Power & Fuse:
The RCI-800 is typically powered from 120VAC and protected by a 500mA
SLOBLO fuse. It can be wired for 240VAC operation by removing (de-
soldering) power jumpers J1 & J2 and installing (soldering) jumper J3.
When changing the RCI-800 to 240VAC power make sure to change the
fuse to half of its value, 250mA. This is important since at 240VAC the RCI-
800 requires only half the current as if it were powered from 120VAC.
Proper protection is only achieved by reducing the fuse value as mentioned
above.
DC Power & Battery Backup:
The RCI-800 may also be powered from a 24VDC source which could be a
battery or a DC power supply. The 24VDC power input is polarity protected
with a fuse to prevent damage to the RCI-800 by inadvertent reverse polarity.
A DC fuse provision is also provided if this power option is utilized. Insert a
5A automotive type blade fuse into the Battery Fuse socket.
A separate 1A fuse protects the 24VDC power output to field transmitters (+24V terminal on
analog inputs). This fuse is located on the analog input output board (bottom board).

..\Manuals\RCI-800-MDM rev.C.doc Page 2 of 15
Inputs:
The RCI-800 has eight dry contact inputs and eight 0-20mA inputs. The dry
contact inputs are excited with 24VDC and will source approximately 20mA
when the contact is closed. A red LED lights up when a contact input is closed.
The analog inputs are configured as 0-20mA inputs and have a 250Ωinput
impedance. Each input terminal has three connections: +24V, I/P, COM. The
+24V power output may be used to power field transmitters. Up to 125mA may
be used to power a transmitter. The input signal is connected to I/P(+) and
COM(-).
Analog inputs are connected to the RCI-800 in two fashions: 1) Normal (3-wire connection) or 2) two-
wire connection. On a 3-wire connected input, an external power supply or the +24V power output
terminal of the RCI provides power to the field transmitter. The field transmitter has a current source
that provides the 4-20mA signal back to the RCI-800. If using the power supply of the RCI-800, the
field transmitter may draw up to 125mA. A total of 1A is available to power up to 8 field transmitters.
On a 2-wire connected input, the field transmitter receives power from the RCI-800 and superimposes
the signal onto the power return path. A maximum of 20mA will flow in such a connection. Make sure
to consult the field transmitter manual to determine how to connect it to the RCI-800.
Outputs:
The RCI-800 has eight form ‘C’ relay contact outputs and eight 0-20mA analog
outputs. The relay contacts are capable of switching 120VAC, 10A or 240VAC, 6A.
An energy absorbing varistor is installed across each contact to limit switching
transients. A ninth relay contact acts as a communications fail indicator. If no
communication occurred within 60 seconds, this relay contact will energize. Upon re-
established communication this relay will de-energize again.
The eight analog outputs are typically configured as 0-20mA outputs and
can drive into a 1000Ωload each, provided that the power supply to the
unit is not below 24VDC. The outputs are not isolated from each other
or from the inputs. Care must be taken when connecting the outputs to
different devices so that no inadvertent ground loops are established.

..\Manuals\RCI-800-MDM rev.C.doc Page 3 of 15
Output Calibration & Input Testing:
The outputs on the RCI-800 are factory calibrated and should not
require any adjustments. To check the calibration of the outputs and relays
use jumpers H1-7 & H1-8 as shown below to set them to known states. If an
output should require some adjustment, the main circuit board has to be
removed from the analog input/output board to gain access to the output
calibration potentiometers. With the power off, remove the main circuit
board and set it aside leaving it connected to the analog input/output board
via the 4-conductor I/O cable. Turn the power on and insert jumper H1-8 on
the main circuit board and turn the OUTPUT CALIB. trim pot for a particular
output until that output reads 20mA. Turn the power off again before re-
assembling the unit.
If both jumpers are IN the analog and contact inputs are passed straight through to the analog and
relay outputs. This may help in troubleshooting input and output signals.
Make sure both jumpers are removed before resuming normal operation.

IN OUT Outputs=0mA, Relays=De-energized
IN IN Outputs=Inputs, Relays=Contact Inputs

..\Manuals\RCI-800-MDM rev.C.doc Page 4 of 15
RCI-800 Configuration:
The RCI-800 requires no configuration other than for its communication fail operation. In the event of a
communications failure on the communications board, the RCI-800 can be set up to take various
actions on its outputs. This may be desirable in order to place connected devices into a safe operating
mode. By default factory setting, all outputs remain at their last known state if a communications failure
occurs.
1) If H1-3=IN then all analog outputs will ramp to the either 0% or 100% depending on jumper
H1-4. the outputs will change at a rate determined by the jumper H1-6.
2) The low end of the output value can be selected to be either 0mA or 4ma depending on
jumper H1-5. This setting only applies to the output value during a fail condition when the
outputs are selected to ramp to 0%. If jumper H1-5 is out, the outputs will ramp to 0mA, if it
is in they will ramp to 4mA. The setting of this jumper does not affect the outputs during
normal operation.

MDM Communication Option:
The -MDM communications option to the RCI series utilizes a 2400-BAUD modem to exchange the
signal data between a host and its remote(s). There are two types of Operating Modes that can be
configured: 1) Answer-Only and 2) Answer-and-Originate.
In Answer-Only mode the RCI-800-MDM will only answer incoming calls. It will not initiate calls to
other devices. This is useful when only periodic data exchange is required. Typically a computer or
PLC places a telephone call via a standard modem, the RCI-800-MDM answers and the two can now
exchange data until the computer or PLC terminates the call.
In Answer-and-Originate mode the RCI-800-MDM operates just like in the Answer-Only mode with the
additional capability of placing a call to another RCI-800-MDM or to a computer or PLC. A
configuration procedure allows the programming of events or time intervals when the RCI-800-MDM is
to place a call. This is useful where unattended, periodic data exchange is necessary. It is also useful
when long distance charges apply to a call since the units can be programmed to communicate only
when there is a change of status at one site or the other. Both units can be programmed to operate in
the Answer-and-Originate mode thus providing bi-directional status change updates.
Modem configuration is done via a bank of DIP switches. The switches are located on the
communications board just to the left of the telephone jack. They are a slanted rocker type that flips up
for OFF and down for ON.
In Answer-Only mode, SW1 is used exclusively to
set all operating parameters (see Answer-Only
Mode Configuration below). In Answer-and-
Originate mode, SW1 is not used and all switches
must be in the OFF (UP) position. Instead the RS-
232 connection is used to exchange a
configuration file with a PC or laptop. This is
necessary because of the large number of
parameters that are required to be configurable for
flexible dialing operation (see Answer-and-
Originate Mode Configuration below).
Answer-and-Originate Topologies:
The -MDM communications option to the RCI series utilizes dial-up telephone transmissions to
exchange the signal data between a host and its remote(s). There are two types of Topologies that
can be configured: 1) Point-to-Point and 2) Host-to-Multipoint.
In a Point-to-Point
topology one host
communicates with one
remote. The two
exchange all their
signals with one another.
The remote is configured as remote #1 even though it is the only remote in the system.

..\Manuals\RCI-800-MDM rev.C.doc Page 6 of 15
In a Host-to-Multipoint
topology one host
communicates to several
remotes. Each remote is
assigned an address
(1,2,3, etc.) so that the
host may distinguish
between them. There
may at most be as many
remotes as there are
inputs & outputs on the
host.
For example, an RCI-800
system, having eight
analog/contact inputs and outputs, may communicate with up to four remotes each having two
analog/contact input and output. In this case all #1 & #2 inputs and outputs on the host correspond
to the #1 & #2 inputs and outputs on remote #1 and all #3 & #4 inputs and outputs on the host
correspond to the #1 & #2 inputs and outputs on remote #2. The second analog/contact input and
output on each of the two remotes would be unused.
Modem Mode Configuration:
The modem communication board has one bank of 8-position DIP switches: SW1. SW1-8 controls the
mode of operation of the modem:
Answer-Only Mode Configuration:
To make an RCI-800-MDM operate as an Answer-Only unit, make sure that SW1-8 is flipped DOWN.
Set the number of rings before the RCI-800-MDM is to
answer using SW1-1, -2, -3. These switches are binary
encoded as shown in the chart to the right. If the RCI-800-
MDM is to ignore all incoming calls (during maintenance for
example) make sure SW1-1, -2 & -3 are all in the up position.
Next, set the number of channels of each remote using SW1-4,
-5. One channel is considered 1 analog input/output plus 1
contact input/output. Hence an RCI-800 can have at most 8
channels.

RCI-MDM Configuration.vi
General
FIRMWARE It is very important that you
select the correct firmware for your specific
RCI-MDM unit. You can find this information by
reading the top label of the microchip in your
RCI-MDM. There are 3 types of Modems:
‘K’, ‘L’, and ‘M’.
MODE This defines if the unit is a host or a
remote. If it is a remote it further identifies the
remote address. This is especially important in
multi-remote systems.
Allowable values:
0 = Host, 1 thru 8 = Remote1 thru Remote8
REMOTES Number of remotes in the system.
In a multi-remote system, this tells the host how
many remotes it has to call when it initiates a
call.
Allowable values: 1 thru 8
HOST CHANNELS Number of channels to be
used on the host. All channels of all remotes in
any system must add up to the number of
channels on the host.
Allowable values: 1 thru 8
REMOTES CHANNELx Number of channels to
be used on this remote. Total channels of all
remotes in a multi-remote system must not
exceed HOST CHANNELS. (x=1..8)
Allowable values: 1 thru 8

..\Manuals\RCI-800-MDM rev.C.doc Page 8 of 15
AUTODIAL The auto-dial time interval in
minutes. If this parameter is set to 0 then the
unit will NOT automatically initiate a call and will
call only when a DI or AI status changes (see
below). If this parameter is set to a value
greater than 0 then the unit will place a call
automatically in this time interval.
Allowable values:
0 = no auto-dial
1-65535 auto-dial interval (min.)
REDIAL Number of times the unit will attempt a
re-dial if the previous dial failed to establish a
connection (because of busy signal, reorder
signal, etc.). If the unit does not establish a
connection after the set number of redials it
suspends the re-dial procedure for the specified
Redial Interval minutes. New events that will
require a call to be placed will re-initiate the
dialing procedure.
Allowable values:
0 = re-dial until successful
1 thru 9 number of re-dials
REDIAL PAUSE Time interval, in seconds, the
unit waits between re-dials. To prevent ongoing
contention between units it is recommended
that every unit in a system be assigned a
different PAUSE interval. That way if two units
happen to call at the same time, they wait
different intervals before re-dialing.
Allowable values:
10-255 = re-dial interval in seconds
(note the 10 second minimum)
REDIAL INTERVAL Time interval, in minutes,
the unit waits between each redial cycle. The
unit will continue to execute redial cycles until a
connection is established.
Allowable values:
0-65535 = re-dial interval in minutes
RINGS The number of rings before the unit
answers an incoming call.
Allowable values:
0 = never answer a call
1 thru 9 = rings before answer
REDIAL FAIL Number of redials executed
before the fail contact is activated.
Allowable values:
0 = continuous
1 thru 9 = attempts before fail signal
Redial Example Diagram

..\Manuals\RCI-800-MDM rev.C.doc Page 9 of 15
CONNECT Time interval, in seconds, the
calling unit stays connected before it terminates
the call. While two units are connected they
continually exchange their data. This is useful
when an immediate confirmation is required
after sending an action to the other unit.
Allowable values:
5-255 = connection duration in sec.
(note the 5 second minimum)
POWER-UP DIAL This setting determines if
the unit will initiate a call at power-up. The unit
can be forced to place a call in ‘PAUSE’
seconds after it is first powered up. This is
useful to re-establish proper input and output
settings after a power failure.
Allowable values:
NO = NO dial at power-up
YES = DIAL in PAUSE seconds after
power-up
TIMEOUT Time interval, in seconds, to wait
for called unit to answer. If the called unit
does not answer in this time, the call is
considered unsuccessful.
Allowable values:
10-255 = wait interval in seconds
(note the 10 second minimum)
COM Select the COM Port to which the
RCI-MDM is connected.
READ RCI Obtains configuration values that
are stored in the RCI-MDM.
WRITE RCI Sends values to the RCI-MDM.
SAVE Allows you to save the configuration to a
text file on your hard drive.
LOAD Allows you to load a configuration file
from your hard drive.
RESET VALUES Resets all values to default
settings.
QUIT Exits the Program.
DISPLAY Shows application processes, status
and errors that occur.

..\Manuals\RCI-800-MDM rev.C.doc Page 10 of 15
DI Status Dialing
Determines whether or not a call will be
initiated when a Digital Input changes its status.
If NO is selected for an input, no call will be
made if its status changes. However, if YES is
selected, whenever that digital input switches
from open-to-closed or closed-to-open, a call
will be made.
If this unit is a remote, then a call will be
placed to the host. If this unit is a host then a
call will be placed to the remote that
corresponds to this input channel.
Allowable values:
NO = no call on status change
YES = call on status change
AI Level Dialing
Determines if a HIGH/LOW level on Analog
Input x (x=1,2,..8) causes a call to be placed. If
this unit is a remote, then a call will be placed to
the host. If this unit is a host then a call will be
placed to the remote that corresponds to this
input channel.
A HIGH level occurs when the input value
rises above this parameter. When the input
level drops below 2% below this parameter the
level is considered NORMAL and another call
will be placed automatically.
A LOW level occurs when the input value falls
below this parameter. When the input level
rises above 2% above this parameter the level
is considered NORMAL and another call will be
placed automatically.
Allowable values:
0 = no call on HIGH and/or LOW level
1-65535 = call on HIGH and/or LOW level
and call when HIGH and/or LOW level
returns to NORMAL
The parameter is calculated as follows:

AI % Dialing
Determines if a specific amount of change on
Analog Input x (x=1,2,..8) causes a call to be
placed. If this unit is a remote, then a call will
be placed to the host. If this unit is a host then
a call will be placed to the remote that
corresponds to this input channel.
The amount of change required before a call
is placed is expressed as a percentage of full-
scale signal. Be aware that a full-scale signal is
from 0-20mA. Hence a 5% change would be
1mA. A call will be placed if the input signal
either rises or falls more than the specified
percentage compared to the signal level at the
last call.
Allowable values:
0 = no call for percent change
1-50 = call on % change from NORMAL
Phone Numbers
HOST The phone number of the host. It
may be up to 15 characters long and may
contain only digits and commas (,). A comma
inserts a 2 second pause into the dialing
sequence which may be necessary if the unit
is on a PBX system where it needs to dial a
number for an outside line and then wait
before it dials the rest of the phone number.
REMOTE1 The phone number for REMOTE 1.
The same rules apply as for the HOST
:
:
REMOTE8 The phone number for REMOTE 8.
The same rules apply as for the HOST

Downloading & Uploading Configuration Data:
To download the internal configuration data of the RCI-800-MDM or upload new
configuration data it must first be place in PROGRAMM mode.
1. Turn the power switch OFF.
2. Locate configuration jumper H7 on the modem board and
insert jumper H7-1 only.
3. Locate Communication Select jumper H5 on the modem
board and move the two jumpers from the NORM position
into the PROG position.
4. Connect the serial cable to the RS-232 connector on the
modem board and to your serial port on your computer.
5. Make sure you have your serial port software running on your
computer.
6. Turn the power switch back on and wait at least 5
seconds.
You can now download and upload configuration data as many times as
necessary until the unit is configured properly. We suggest that you
download the configuration data again after you have uploaded it to make
sure that the RCI-800-MDM accepted it properly.
Upon completion turn the power switch OFF again, remove jumper H6-1,
move jumpers H5 back to the NORM position, disconnect the serial cable
and finally turn the power switch back on.
Download Configuration Data:
1. Make sure your serial software is ready to capture incoming serial
data.
2. Press the DIAL button on the modem board.
3. The RCI-800-MDM will now send all of its internal configuration
data, which is being captured, to a file by the computer. The red TX
(transmit) LED will light or blink during this operation and you should
see the data on your screen. When the red TX LED stops flashing the download is complete.
Note: If you are not receiving any data on your
computer one possible reason may be that your
Transmit and Receive lines in the RS-232 cable
maybe crossed
Straight-Thru Cable
Null-Modem Cable

..\Manuals\RCI-800-MDM rev.C.doc Page 13 of 15
4. Stop the data capture on the serial port software.
You can now modify this file based on your requirements (see Configuration File Details below) and the
upload the file back to the RCI-800-MDM.
Uploading Configuration Data:
Make sure your configuration file has been carefully modified so that it is free of errors.
1. Follow the file upload procedure for your serial port software to send the configuration file.
2. During the upload process you will see the green RX (receive) LED light or flash. Once the green
LED stops flashing the upload process is complete and the RCI-800-MDM will reply with one of two
messages:
CONFIG ERROR The configuration file was received incorrectly or it has an error
in it. Examine the file closely and/or try to re-send it.
SAVING CONFIGURATION The file was received correctly and is now being stored in the
RCI-800-MDM’s non-volatile memory. Wait for the RCI-800-
MDM to display the DONE message before moving on (this
should take about 5 seconds)
Configuration File Details:
The RCI-800-MDM configuration file is a human-readable text file that defines the various operating
parameters of the Answer-and-Originate Mode. The file is very simple in structure. Modifications can
be made easily with a text-editing program however care must be taken to adhere to a few constraints.
1. The first line of the configuration file must read $RCI-MDM. The ‘$’ is very important. During a
configuration file upload the ‘$’ tell the RCI-800-MDM that a configuration file is being sent.
2. Any line starting with a semi-colon ‘;’ is considered a comment line. There may be unlimited
numbers of these lines in the configuration file. This is useful to make notes about the
parameters to the user. These comment lines are not stored in the RCI-800-MDM!
3. The sequence of parameters may NOT be changed in any way.
4. The length of parameters must be exactly as present. If a parameter consists of 5 digits you
must pad it with leading zero’s to make it 5 digits long. Single digit parameters may only be one
digit. Be careful not to add any spaces at the end of the numbers!
5. Phone numbers are exempt from constraint 4. They may be any length up to 15 characters.
Following is the default configuration file of an RCI-800-MDM as it is shipped from the factory. Note the
large header at the top consisting of comment lines (starting with ; ). This is a brief explanation of all
the parameters and serves as a quick reference for a user who doesn’t have access to this manual
while performing a configuration.

..\Manuals\RCI-800-MDM rev.C.doc Page 14 of 15
Above is the header portion of the configuration file. It serves as a quick reference and it is sent out by
the RCI-800-MDM every time the configuration data is downloaded. It immediately precedes the actual
configuration data.
