Introduction
The InterOP8500 mounts directly to a Johnson
Controls panel, replacing the Johnson FIC-1n1
control board and the PCR-102. The
InterOP8500 uses the same mounting
brackets and can be powered by the existing
power supply (using a special adaptor cable).
However, in order to retain the UL listing, the
RPA-105 and the LPS-105 must be replaced by
the PWRSUP8500.
In addition, the InterOP8500 uses the Johnson
field termination board (FTB-102) for binary
I/O and analog input. Please note that slave
FICs must be replaced by separate, stand-
alone InterOP8500 modules.
The InterOP8500’s edge connector plugs
directly into the field termination board’s
socket. Once connected, the InterOp8500
accesses the binary and analog I/O, as well
as an isolated 12VDC power supply for its
binary outputs. The InterOP8500 board
contains the microprocessor, a connection
port for the network connection, and a port
for I/O expansion. The InterOP8500 has 8
binary inputs, 15 analog inputs (which can be
set to either RTD or voltage mode), and 16
digital outputs.
The Access Port allows communication with
WebCTRL or SuperVision. The InterOP8500's
keypad port provides the interface for serial
communications with a BACview1or
BACview2keypad display. Refer to the
BACview1or BACview2 Hardware Technical
Instructions for more information on small
and large keypad display.

Mounting
CAUTION
CAUTIONCAUTION
CAUTION Changes or modifications to this
unit not expressly approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
1. Remove all power to the Johnson Controls
panel.
2. Open the face of the Johnson Controls
panel. The panel may contain up to three
Johnson Controls boards which face the
front of the panel and a side-mounted
board.The facing boards are stacked
above one another and are located
adjacent to the field termination board.
Remove the facing boards and any cables
(called "RPA wires") connected to them.
3. The InterOP8500 mounts directly to the
field termination board using either the
PWRSUP8500 or the existing power
supply (RPA-105 and LPS-105) as shown
in Figure 3 on page 5 and Figure 5 on page
6. Connect the InterOP8500 edge
connectors to the field termination
board's socket. Lock the InterOP8500 in
place with the plastic retainers provided
in the panel.
4. Place the brushed aluminum ALC label on
the door of the panel.
Connecting Expander Modules
Up to five expansion Mx modules can be
connected to an InterOP8500. The stack can
be arranged in a single column using the
optional expansion cable.
NOTE
NOTENOTE
NOTE Use only one expansion cable per
stack.
Addressing
Before setting or changing the address, make
sure the InterOP8500’s power is off. The
InterOP8500 only reads the address when the
module is turned on. After changing the
address, you must transfer memory to the
module. Refer to “Transferring Memory” on
page 17.
The InterOP8500 has two rotary switches for
addressing:
• For WebCTRL systems, use the switches
to assign the device’s MAC (medium
access control) address on the BACnet-
over-ARCNET network segment. The
rotary switches define the MAC address
portion of the device’s BACnet address
which is composed of the network
address and the MAC address.
• For SuperVision systems, use the
switches to assign the device’s module
number.
One switch corresponds to the tens digit and
the other corresponds to the ones digit. For
example, if the module’s address is three, set
the tens switch to zero and the ones switch to
three, as shown in Figure 4 on page 5.

Revised 7/10/01 • InterOP8500 5 © 2001 Automated Logic Corporation
Power Wiring
The InterOP8500 module is designed to
accept power directly from either the
PWRSUP8500 or the existing Johnson power
supply (LPS-105 and RPA-105). In order to
retain the UL listing of your system, a field
inspection is required if using a Johnson
power supply or the RPA-105 and the LPS-105
must be replaced by the PWRSUP8500 or.
Refer to “Using the ALC Power Supply” on
page 6 for wiring with the PWRSUP8500, or to
“Using the Johnson Power Supply” on page 7
for wiring with an existing Johnson power
supply.
Whenever possible, make sure the module's
power and communications connections are
working properly before connecting any
inputs and outputs. Care should be taken to
isolate power wiring from all other wiring
inside the enclosure. The high and low
voltage wiring must be kept as far apart from
each other as is possible to avoid noise
interference.
NOTE
NOTENOTE
NOTE To protect analog signals from stray
noise and to minimize EMI, use shielded
cable on all signal wires and low voltage
power wires.
When entering, exiting, or interconnecting
with the enclosure, it is better to use several
small openings than one large one. The 12V
binary outputs are powered by a separate
source supplied through the field termination
board.
CAUTION
CAUTIONCAUTION
CAUTION The InterOP8500 module is a
Class 2 device (less than 30VAC.) Take
appropriate isolation measures when
mounting an InterOp8500 module where
non-Class 2 devices or wiring are present.

Using the ALC Power Supply
The PWRSUP8500 power supply replaces both
the Johnson Controls LPS-105 and Johnson
RPA-105. The PWRSUP8500 is designed to fit
into the previous power supply's mounting
bracket and power the InterOP8500. The
PWRSUP8500 does not require any adaptor
cables. It connects directly to the
InterOp8500's power connector.
CAUTION
CAUTIONCAUTION
CAUTION The PWRSUP8500 module is a
120VAC device. Take appropriate isolation
measures when mounting a PWRSUP8500.
1. Turn the power switches off on the
InterOP8500 and the Johnson Controls
panel.
2. Unplug the LPS-105 from the power outlet
(see Figure 5).

Using the Johnson Power Supply
1. Verify that the InterOP8500 is addressed
correctly.
2. Turn the Johnson Controls panel power
switch off.
3. Turn the InterOP8500 power switch off
(see Figure 1 on page 2).
4. Use the Power Adaptor Cable shown in
Figure 6 to connect power from the
Johnson power supply to the InterOP8500.
There is only one way for the connectors
on the cable to properly connect to the
indicated J terminals - do not force the
connectors on the wrong terminal.
5. Connect a grounding wire from the
chassis of the panel to the earth ground
terminal of the InterOp8500. See Figure 5
on page 6 for wiring.
6. Turn the InterOP8500 power switch on.
7. Turn the panel power switch on.
8. Make sure that the Communications
Power, Logic Power +5V, and Power +12V
LEDs are lit (located at the top edge of the
InterOp8500 board). See “LEDs” on
page 18.
Network Communications
The InterOP8500 module supports several
communications options through its CMnet
port.
On a SuperVision system, the InterOP8500
module can connect to a BACnet-over-
ARCNET network segment at 156 kbps, or to
a legacy CMnet at 9600 bps or 38.4 kbps.
When communicating at 156 kbps, the
network segment uses a unique
implementation of the industry standard
BACnet-over-ARCNET protocol called
ARC156. For a summary of the differences
between ARCNET and ARC156, please refer to
ARC156 CMnet Wiring Technical Instructions.
Use the appropriate wire for network
communications. When using an ARC156
network, use an A3ARC156 wire available
from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
[phone]
Use a dedicated 22AWG to 18AWG twisted
pair wire for legacy CMnet (EIA-485) wiring.
For more information about CMnet wiring,
refer to the Technical Handbook or to ARC156
CMnet Wiring Technical Instructions.
1. Be sure the module’s power is off before
wiring it to the network.
2. Check the network communication wiring
for shorts and grounds.
3. Connect the appropriate communications
wires to the module’s screw terminals as
shown in Figure 7 on page 8. Be sure to
follow the same polarity as the rest of the
network.
4. Make sure the module is configured for
the correct baud rate. All modules on the
Figure 6. Power Cable

Revised 7/10/01 • InterOP8500 8 © 2001 Automated Logic Corporation
network segment must use the same baud
rate.
On an ARC156 network segment (156
kbps), set the Comm Mode jumper to
ARC156 (see Figure 8 for the switch’s
location). The baud rate selection does
not matter in this case.
If you are using a legacy CMnet (9600 bps
or 38.4 kbps), set the Comm Mode jumper
to CMnet, and use the baud rate DIP
switch to determine the baud rate (see
Figure 9 and Figure 10).
NOTE
NOTENOTE
NOTE Setting the Comm Mode jumper
to CMnet disables the industry standard
BACnet-over-ARCNET (ARC156) protocol
for the network segment and enables the
proprietary ALC CMnet protocol.
You can verify that the InterOP8500 is
communicating on the network segment by
making sure the transmit and receive LEDs
are active.
Communicating with the
Wo r k s tat i o n
When using SuperVision, you can connect a
workstation or portable computer directly to
the InterOP8500 module using an APT and the
module’s Access Port (see Figure 11). This
type of connection can be used to
troubleshoot the module or transfer memory.
If you are using an ARC156 network segment,
you can receive colors while connected to a
module’s Access Port if a gateway module is
on the network segment. You cannot receive
alarms through the Access Port, however.
The baud rate of the Access port is
determined by the first switch on the eight-
position DIP switch (see Figure 7). If you need
to change the switch’s position, turn the
InterOP8500 module off first. Once you have
adjusted the switch, turn the module back on.

EIA-232 port of the APT using a standard
straight-through serial cable.
2. Set the APT’s Mode Select switch.
• On an ARC156 network segment, use
the TTL setting.
• On a legacy CMnet, use the 485 setting.
3. Connect the Access port of the APT to the
Access port of the module.
4. In SuperVision, define the connection type
using Table 1.
Input/Output
The InterOP8500 is equipped with 8 binary
inputs, 15 analog inputs, and 16 binary
outputs. Any of the analog inputs can be used
as digital inputs. Table 2 summarizes the
requirements for conductors between the
Johnson Controls field devices and the
termination board.
All wiring to remote devices must be kept
separate from power wiring in the area.
Exposed drain wire at the termination board
should be kept as short as possible, not
exceeding two inches (5 centimeters). All field
devices should be terminated using a
correctly sized wire nut or, when terminals
are provided, a solderless crimp-type
connection should be made.
Analog Inputs
The InterOP8500 provides access to 15 analog
inputs through the Johnson Controls field
termination board. Use the formulas in the
“Calculating Offset and Gain” on page 12
section to read signals from these inputs.
There are four field terminals for each AI
point 1 through 7, and five for each AI point 8
through 15 (see Figure 12 on page 10). The
function of these terminals is as follows:
Termination Row 1 This terminal is for
analog inputs and is connected to a
multiplexer.
Termination Row 2 This terminal is
connected to a regulated +2.5VDC supply.

Termination Row 3 This terminal is the
unswitched input signal common.
Termination Row 4 This terminal is not
used.
Termination Row 5 This terminal is the
switched input signal common and is
available only on AI points 8 through 15.
Unswitched and Switched Inputs
Unswitched inputs, the most common type of
input, reference the sensor to the module's
ground, the same ground referenced by all
other unswitched input sensors. This type of
input is for devices that are "floating,"
meaning that they are not ground referenced
anywhere. Examples would be RTD inputs or
dry contacts.
Switched inputs are selected one at a time,
and the circuit board's ground is then
referenced to the module's "Switched
Ground" lead. This feature allows modules
that are not floating, and that may have a
small amount of ground shift, to give stable
readings on their AIs. Examples would be 0-
5VDC or 0-2.5VDC devices.
NOTE
NOTENOTE
NOTE The channel number is not affected
by the input's condition (switched or
unswitched).

1. Turn the Johnson panel power switch off.
2. Determine the type of signal received by
the field termination board. Consult the
Johnson Controls manuals if necessary.
The InterOP8500 must be configured to
receive the same type of input as the
previously removed Johnson boards.
3. Set the InterOp8500 jumpers as follows:
• For RTD mode insert a jumper for the
individual input. The jumpers are
located along the lower right side of the
InterOP8500 board (see Figure 13).
NOTE
NOTENOTE
NOTE If using a solid-state current
switch on a digital input, the resistance
must drop low enough for the module to
recognize it.
• For voltage and potentiometer mode,
remove the jumpers. (Current mode can
be configured by adding an external
sense resistor. For 4-20mA use a 250
ohm resistor Figure 14). Turn the
InterOP8500's power switch on.

4. For each input, enter the point identifiers.
• In WebCTRL, enter the point number
and the point type on the Properties
page. For linear inputs, set the
minimum value and maximum value to
scale the point to engineering units.
• In SuperVision, enter the channel
number, offset, and gain using the
Configure Points or Point Help feature.
Valid channel numbers are listed in
“Channel Numbers in SuperVision” on
page 15.
5. To verify each input’s operation, have
each sensor create a known value and
compare it to the condition reported on
the FB’s Properties page in WebCTRL or
Status page in SuperVision.
Calculating Offset and Gain
You may need to calculate the offset and gain
for analog inputs to ensure the correct value
is read by the InterOP8500. You can also use
the custom translation table on the module
driver Parameter page to read nonlinear
signals from these inputs. Refer to the
“Channel Numbers in SuperVision” on
page 15 for details.
Use this formula to calculate the gain for an
analog input point:
Use this formula to calculate the offset for an
analog input point:
For example, consider a 1 to 4.5V humidity
sensor with a relative humidity of 20 to 90%.
The voltage span is 3.5 volts (4.5V - 1V). The
user unit span is 70% (90% - 20%). Calculate
the gain and offset for a humidity sensor like
this:
Here is an example of a 0 to 2.5V V-9012
feedback sensor with a range of 0 to 100%
relative humidity. The voltage span is 2.5V
(2.5V - 0) and the user unit span is 100%
(100% - 0%). Calculate the gain and offset for
a V-9012 feedback sensor like this:
Binary I/O Power Jumper
The InterOP8500 provides a jumper (see
Figure 1 on page 2 for location) for selecting
between internal and external power for
Binary I/O points. The InterOP8500 provides
isolation for externally powered devices and
no isolation for internally powered devices. If
binary outputs are present, they must be
externally powered and the jumper must be
set to the External position (see Figure 15 on
page 13). If no binary outputs are present,

then binary inputs can be internally powered
(no isolation) or externally powered
(isolated). Note the orientation of the
jumpers.
Binary Inputs
The InterOP8500 provides 8 binary inputs
with direct connection to the Johnson field
termination board. The inputs are for signals
in the range of -38VDC up to +38VDC. A
digital input microblock indicates On for any
voltage between -38.0VDC and 0.9VDC; it
indicates Off for any voltage between 2.5VDC
and 38.0VDC. These inputs are capable of
counting up to 1,000 pulses per second for
use in pulse-counting configurations. Each
binary input can sense either a set of non-
energized contacts, or a two-state DC voltage
level.
The field termination board contains three
terminals for each binary input point (see
Figure 12 on page 10):
Termination Row 1 This terminal is
connected to an input buffer (each input
has a separate buffer).
Termination Row 2 This terminal is the
input signal common.
Termination Row 3 Do not use terminal 3
unless you need to connect an earth
ground.
The common terminals for the binary inputs
are joined to the common terminals for the
binary outputs. All common terminals are
joined to the isolated 12VDC supply's
negative terminal through the field
termination board. This binary ground is
isolated and independent of the logic and
analog supply ground coming from the RPA-
105.
NOTE
NOTENOTE
NOTE All eight binary input terminals are
electrically connected on the field termination
board. To prevent ground loops, electrically
isolate the sources of the binary input signals
from each other.
Binary Outputs
The InterOP8500 provides 16 binary outputs
with a direct connection to the field
termination board. The 16 binary outputs
have suppression. The binary output power
requirement is 13.2VDC, which should be
supplied by an external Class 2 power supply.
The output of this external power supply is
connected to a pair of field terminals located
on the field termination board (see Figure 12
on page 10 for location). The maximum load
through each binary output is 200mA.
The field termination board has terminal
capacity for between 8 and 16 points
depending upon the types of output signals
provided. Each of the eight BO points located
on the termination board consists of six field
terminals. Each of these six field terminals
can provide either one or two independently
controlled binary output points. The function
of these terminals is as follows:
Termination Rows 1-2 These terminals
are independently connected to either
+12VDC or isolated common (depending on
application).
Termination Rows 3-4 These terminals
are connected to isolated common. They are
used with terminals 1 and 2 for fixed-polarity
signals.
Termination Rows 5-6 These terminals
are unused.
NOTE
NOTENOTE
NOTE Terminals 1, 2, 3, and 4 must not be
grounded. Voltages from field devices must

not be fed back into the binary output
terminals.
Three types of output signals are available:
momentary, position, and maintained. The
momentary signal is used to control a
maintained or momentary relay
configuration. The position signal is intended
to control an actuator with a position
transducer or other interface device. The
maintained signal is intended to control a
two-position device by delivering a
maintained 0 or 12VDC signal.
Manual Operation
The HOA switches (SW3 through SW18),
located as shown in Figure 1 on page 2, allow
each binary output to be in placed in Auto,
On, or Off mode (as shown in Figure 16).
To verify each output’s operation, lock the
output to a known condition using the
Function Block’s Properties page in WebCTRL
or Parameter page in SuperVision. Be sure the
equipment operates as specified.
Each digital output can be placed in Manual
or Auto mode by setting the HOA switches
(see Figure 1 on page 2 for the switches’
location). Table 4 shows the status of the
digital output based on the output’s
configuration and the HOA switch position.
You can monitor the status of the HOA
switches through WebCTRL or InterOP8500.
In WebCTRL, assign each switch a digital
input in the FB using the point number and
the HOA Status Feedback point type. In
SuperVision, assign each switch a digital
input in the FB using channel numbers 81
through 80. Channel 81 corresponds to HOA
switch number one, channel 82 corresponds
to HOA switch two, and so on. Switches 10
through 15 use channel numbers 8A through
8F, and switch 16 uses channel number 80.
An off status means the HOA switch is in Auto
mode. An on status means the HOA switch is
in Manual mode.

Point Identifiers
A point can be identified in WebCTRL by its
point number and point type; in SuperVision,
a point is identified by its channel number. On
both systems, expander number zero
represents I/O points on the InterOP8500.
Point Identifiers in WebCTRL
Enter the point identifiers in Eikon for
WebCTRL before the FB is made or on the
point’s Properties page in WebCTRL. Set the
type, number, and any other required
parameters for each point on the
InterOP8500.
1. Select a physical point type from the Point
Type field.
NOTE
NOTENOTE
NOTE To determine the physical point
type of an analog input, see Table 3 on
page 10.
2. If the physical point type is linear, enter
the appropriate minimum and maximum
present values on the microblock’s dialog
box.
For example, on a 0-5VDC sensor, enter 0
as the minimum and 5 as the maximum.
3. Enter the number of the input or output in
the Input or Output Number field.
NOTE
NOTENOTE
NOTE Points are numbered starting with
1 for each point type. For example, HOA
Status output numbers would start at 1
and could go up to 16; likewise, RTD input
numbers would start at 1 and could go up
to 15.
4. Enter an expander number if needed.
Channel Numbers in SuperVision
The following table shows the valid channel
numbers for each point on the InterOP8500.
The offset and gain values used depend on
the type of sensor or actuator attached to the
I/O point. You can select the channel number,
offset, and gain using SuperVision’s Point
Help feature or Configure Points utility.
Alternatively, you can preconfigure the points
by manually entering the channel number,
offset, and gain in Eikon using the values
shown in the following tables.

Transferring Memory
You should download memory whenever you
make changes to your modules (for example,
change the module number, upgrade the
module driver, or change the FB).
The InterOP8500 module can store one
module driver and several FBs. The number
of FBs stored depends on the software you
are using (see the table on page 3).
NOTE This type of download should be
performed with caution. When the module is
automatically restarted before and after
transferring memory, any equipment
controlled by the module is shut down and
restarted. Downloading memory also
overwrites all Function Blocks in the module
causing the module to lose any stored data.
Transferring Memory in WebCTRL
The InterOP8500 module using the
DRV_InterOP8500 module driver can store up
to 100 FBs, depending on their size. You must
be logged in to WebCTRL with the appropriate
privilege to download memory.
1. Click the CFG button at the bottom of the
navigation pane.
2. Click Download in the CFG tree control.
3. Click the Memory, Parameters, or
Schedules boxes, depending on what you
want to download.
NOTE A memory download includes a
parameter and schedule download.
4. Expand the tree in the action pane, click
the module you want to download to,
then click Add. Click on and Add any
other modules you want to download to.
5. Click the Execute Download button.
If any downloads failed, they are listed in
the Failures section under the tree in the
action pane. To retry a failed download,
click on the module in the Failures list,
click Add, and click the Execute
Download button again.
NOTE Since a failed download indicates
a system problem, you should never clear
a failure. Locate and resolve the problem,
then retry the download.
6. Click the Properties button to refresh the
screen. This removes the items from the
Download Items list.

Transferring Memory in SuperVision
The InterOP8500 module using the 85M
module driver can store up to 59 FBs,
depending on their size.
1. Log in to SuperVision on a workstation
connected to the module network. You
can also connect directly to the module
using the Access Port; see
“Communicating with the Workstation” on
page 8.
2. Navigate to the module driver and look at
the module status report in SuperVision to
make sure the module type and number
agree with the module.
• To view the module status report in
SuperVision v3.0, click Tools -
Troubleshooting - Module Status.
• To view the module status report in
SuperVision v2.6b, press the Esc key,
type MO ,,module address,15 and
press Enter.
3. Transfer memory to the module.
• In SuperVision v3.0, click Tools -
Troubleshooting - Transfer Memory to
Module.
• In SuperVision v2.6b, download
memory for This Module.
4. When the memory transfer is finished,
check the module status report again.
Make sure the FB List shows all the FBs
you intended to transfer.
Troubleshooting
Formatting the Module
If you are unable to communicate with a
module after transferring memory, you can,
as a last resort, manually format the module
to try to restore communication. Formatting
the module erases all memory, so you need to
transfer memory back to the module once it is
formatted.
NOTE Since the module is automatically
formatted when you transfer memory, you
should only manually format the module if
communication was not established after the
memory transfer.
1. Turn the module’s power off. Make sure
the module’s address switches are not set
to ‘0 0’.
2. Press and hold the Format button (see
Figure 1 on page 2 for location).
3. While continuing to hold the Format
button, turn the module’s power on.
4. Continue to hold the button until the Error
LED flashes three times in sync with the
Run LED.
5. Release the Format button.
6. Transfer memory to the module. Refer to
“Transferring Memory” on page 17.
LEDs
The InterOP8500 module has several LED
indicators to show the status of certain
functions. Table 10 on page 19 explains the
Run (LED 3) and Error (LED 4) LED signals in
detail to assist troubleshooting.
LED 1 Rx - lights when the InterOP8500
receives data through the network segment.
LED 2 Tx - lights when the InterOP8500
transmits data over the network segment.
LED 5 Communications Power - Indicates
power is being supplied to the
communications circuitry.
LED 6 Logic Power +5V - indicates power is
being supplied to the logic circuitry.
LED 7 Power +12V - indicates power is
being supplied to the analog circuitry.
LED 8-23 Binary Outputs - indicates 12V
on the individual output.

Revised 7/10/01 • InterOP8500 19 © 2001 Automated Logic Corporation
LED 24 Output Power - indicates power is
being received from field termination board
from the external power supply for binary
outputs and isolated binary inputs.
Protection
The InterOP8500 module is protected by
internal solid state Polyswitches on the
incoming power and network connections.
These Polyswitches are not replaceable and
will reset themselves if the condition that
caused the fault returns to normal.
Production Date
To determine when a module was
manufactured, check the module status
report for the module in WebCTRL or
SuperVision. Refer to the appropriate user’s
guide for more information about the module
status report.
A sticker on the back of the module also
shows the date the module was
manufactured. The first three characters on
the sticker indicate the type of module. The
next two characters show the year and month
of manufacture.
