Basic Installation
DIN Rail Installation Procedure
Installing the ioPAC 8500 on a DIN Rail
The DIN rail attachment plate should already be fixed to the back panel of the ioPAC 8500 when you take it out
of the box. If you need to reattach the DIN rail attachment plate to the ioPAC 8500, be sure the spring-loaded
bracket is situated towards the bottom, as shown in the figures below.
NOTE
A wall
mount kit can be purchased separately.
STEP 1:
If the spring-
loaded bracket is locked in place, push the
recessed button to release it. Once released, you should feel
some resistance from the spring as you slide the bracket up and
down a few millimeters in each direction.
STEP 2:
Insert the top of the DIN rail into the top
slots on the DIN rail attachment
plate.
STEP 3:
The DIN rail attachment unit will snap into
place as shown in the illustration below.
Removing the ioPAC 8500 from a DIN Rail
To remove the ioPAC 8
50
0 from a DIN rail, use a screwdriver to push down
the spring
-loaded bracket until it
locks in place, as shown in the diagram at
the right. Next, rotate the bottom of the switch upwards and then remove the
switch from the DIN rail.

STEP 1: Use screws to attach the wall-mounting kit to the back of the ioPAC 8500, as shown below:
STEP 2: Use screws to fix the wall-mounting kit to a wall.

ioPAC 8500 Hardware Installation
2-4
Module Installation Procedure (Power-Off)
Moxa’s ioPAC 8500 controllers come with 2, 5, or 9 slots for 85M-series modules. Use the following procedure
to install modules when your system is powered off.
Step1:
Install the module into the ioPAC 8500 system. The module’s
PCB should align with the edge of the frame. Push the module into the
slot and make sure the module is plugged into the backplane.
Step2:Fasten the two screws using 3.5±0.5 kg of torque.
Module Installation Procedure (Power-On)
All ioPAC 8500 modules are hot-swappable, which means that you can safely install, remove, and replace
modules while the system is powered on. When a module is removed or installed when the system is powered
on, the module head stops processing and registers the newly installed or recently removed module, and scans
for a configuration change. There is no disruption to normal operation during module insertion or removal.
After installing a new module, it could take about ten seconds for the system to recognize and activate the
module, at which point the module’s LED will turn green.
WARNING
When the system is
powered on, do not install more than one module at a time. If you need to instal
l multiple
modules, wait until the most recently installed module’s LED turns GREEN before installing the next module.
Configuring Power
Powering on the ioPAC Controller
The ioPAC controller can receive power from a 9 to 48 VDC power source, and is compliant
with EN 50155 at 24 VDC. Input power is applied to the positive (V+) and negative (V
-)
terminals on
the connector.
•
When the input voltage is below the minimum recommen
ded voltage the ioPAC will turn
off.
•
The ioPAC has reverse protection and power input over-voltage protection, allowing it t
o
resist a maximum voltage of 60 V, and the ioPAC’s power input over-current fuse
protection specification is 5 A.
After connecting the Moxa ioPAC controller to the power supply, it will take 30 to 60 seconds for the operating
system to boot up. The green Ready LED will illuminate continuously until the operating system is ready.

ATTENTION
This product is intended to be supplied by a Listed Power Unit with output marked “LPS” and rated for 9
-
48 VDC
(minimum requirements). For railway rolling stock applications, these devices must be supplied by a galvanic
isolated power supply with design
based on the EN 50155 standard.
Installing a microSD Card
The ioPAC is equipped with one slot for a microSD card. The card reader slot is located inside the ioPAC device,
so you will need to unscrew and remove the card cover to install your microSD card. When inserting a microSD
card, remember to keep the front edge of the card facing down.
Follow these steps to remove or install a microSD card:
1. Remove the screw holding the card cover in place.
2. (a) Insert the microSD card into the microSD card slot, or
(b) Remove the microSD card from the microSD card slot.
3. Fasten back the screw holding the card cover in place.

System LEDs
PWR (Power LED)
The Power (PWR) LED indicates the status of the system power. When the system is on, this LED will turn green,
and when the system power is off this LED will be off.
RDY (Ready LED)
The Ready (RDY) LED indicates the status of the system’s kernel. When the LED is green the system kernel is
ready. When the LED is green and blinking, the system’s kernel is booting-up. When the Ready (RDY) LED is red,
there is either a system error or the system is being reset to factory defaults. When the Ready LED is red and
blinking, the device’s factory default mode has been triggered.
IO (Expansion Module LED)
The IO LED on the module indicates the status of the expansion modules. When the LED is green, all expansion
module configurations are okay, and when the LED is red, at least one of the expansion modules failed to
configure properly.
C/C++ Version LEDs: LED1 and LED2
The ioPAC controller allows the user to custom configure these two LEDs (through the software interface).
Refer to the C/C++ Sample Code Programming Guide for ioPAC RTU Controllers for details.

ioPAC 8500 Hardware Installation
2-8
IEC-61131-3 Compliant LEDs: R/S and ERR
The ioPAC controller supports IEC-61131-3-compliant Run/Stop and Error (ERR) LEDs for ISaGRAF-specific
notifications. These LEDs are not user configurable.
Communication LEDs
P1 and P2
The ioPAC controller comes with two serial connections. P1 and P2 represent the status of each serial
connection. When the LED is green, the ioPAC is transmitting data (Tx). When the the LED is amber, the ioPAC
is receiving data (Rx). When the LED is blinking randomly, data is either being transmitted or received. For
example, if P1 is blinking and is green, the ioPAC is transmitting data.
When the LED is off, the serial connection is disconnected.
LAN1 and LAN2
The ioPAC controller comes with two Ethernet ports, with the LAN1 and LAN2 LEDs used to represent the status
of the two connections. When the LED is green, data is transmitting at 100 Mbps. When the LED is amber, data
is transmitting at 10 Mbps. When the LED is blinking, data is being transmitted. When the LED is off, there is
no Ethernet connection, or the Ethernet connection has been disconnected.
The Toggle Switch
The toggle switch functions differently depending on the programming language set your ioPAC model is
configured for.
In IEC-61131-3 Models
For IEC
-61131-3 models, the toggle switch is a simple run/stop switch for IEC
programs.
Users can enable or disable it through RTUxpress. T
he default setting
is disabled.
In C/C++ Models
On models that use the C language set, the toggle switch is programmable,
giving integrators and end
-
users a switch that can trigger one of two operation
modes
(refer to the C/C++ Sample Code Programming Guide for ioPAC
RTU Controllers
for details).

ioPAC 8500 Hardware Installation
2-9
Toggle Switch: Factory Reset Process
Use the following procedure to reset the ioPAC to the factory defaults. Note that when you reset the ioPAC, all
of your tag definitions, software programs, and files will be deleted, and the service and runtime engine will be
restarted.
1. When the system is booting up and the RDY LED is blinking GREEN, hold the toggle switch in the “reset”
position.
2. Continue to hold toggle switch until the “RDY” LED turns a solid RED, and then release the toggle switch. It
will take around 90 seconds to complete the factory reset process.
3. When the “RDY” LED starts blinking GREEN (indicating that the kernel is rebooting), the factory mode is
completed.
NOTE
Do NOT power off, operate, or
connect any devices when the RDY LED is a solid red.
The factory reset function
is only activated when the system is booting up.
Connecting to the Network
Ethernet Communication
Connections to the LAN port are made through an RJ45 or M12 connector on the module. The wiring and pin
connections for these connectors are described in separate sections below.
•TCP/IP Settings: Dual Speed Functionality: The ioPAC 8500’s Ethernet ports auto negotiate with the
connected devices and then use the fastest data transmission rate supported by both devices. The following
table shows the TCP/IP parameters supported by the LAN port. Default values are set when a Factory Reset
is performed on the controller.
LAN Port 1 LAN Port 2
Parameter Supported Values Parameter Supported Values
IP Address Default: 192.168.127.254 IP Address Default: 192.168.126.254
Subnet Mask Default: 255.255.255.0 Subnet Mask Default: 255.255.255.0
Gateway Default: 0.0.0.0 Gateway Default: 0.0.0.0
IP Address is the IP address of the controller.
Subnet Mask determines the subnet on which the controller is located.
Gateway determines how your controller communicates with devices outside its subnet. Enter the IP
address of the gateway.
The IP address, subnet mask, and gateway are static; contact your network administrator to obtain these
addresses for the controller.

RJ45 Ethernet Connector
The ideal maximum cable length of a 10/100BaseT connection is 100 m (350 feet), but the actual limit could be
longer or shorter depending on the amount of electrical noise in the environment. To minimize the amount of
noise, Ethernet cables should not run parallel to power cables or other types of cables that generate electrical
noise.
The following diagram and table shows the pin connections for the RJ45 Ethernet connector:

M12 Ethernet Connector
The ioPAC 8500 has two 10/100BaseT(X) Ethernet ports that use 4-pin shielded M12 connectors with D coding.
The 10/100T(X) ports located on the front panel of ioPAC 8500 are used to connect to Ethernet-enabled devices.
Most users configure these ports for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted
automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of
device (NIC-type or HUB/Switch-type) connected to the port.
•The Auto MDI/MDI-X function (M12 connector) allows users to connect the ioPAC 8500’s 10/100BaseTX
ports to any kind of Ethernet device, without needing to pay attention to the type of Ethernet cable being
used for the connection. This means that you can use either a straight-through cable or cross-over cable to
connect the ioPAC 8500 to Ethernet devices.
The following diagram and table shows the pin connections for the M12 Ethernet connector:
