To access the controller setup through the Service Port:
1 Connect an Ethernet cable from a computer to the controller as shown below.
2 Turn off the computer's Wi-Fi if it is on.
3 If your computer uses a static IP address, use the following settings:
○Address: 169.254.1.x, where x is 2 to 7
○Subnet Mask: 255.255.255.248
○Default Gateway: 169.254.1.1
4 If it uses a DHCP address, leave the address as it is.
5 Open a web browser on the computer.
6 Navigate to http://local.access or http://169.254.1.1 to see the Service Port controller setup
pages.
See To set up the controller through the Service Port (page 29) for general information on using the
controller setup pages.
To set up autobaud
The G5CE can automatically receive or establish the baud rate on a serial network. When you configure
a device on the network for autobaud and then power it up, the device detects the incoming baud rate
on the network and sets its baud to match.
Autobaud does not work unless there is a device on the network, whether Automated Logic® or third
party, that has the baud rate already set. You can manually set the baud rate on more than one device,
as long as the rate is the same for every device.
NOTES
•The received baud rate stays intact during power cycles.
•We recommend you set the baud rate manually on the router for the network.
MS/TP
MSTP Autobaud can be configured in either the:
•Service Port controller setup pages > BACnet tab > Port S1 or Port S2
or
•The WebCTRL® interface, on the Network tree, select your G5CE > Driver > BACnet Router
Properties > MS/TP Configuration on Port S1 or on Port S2. See BACnet Router Properties (page
22).

Rev. 6/9/2022 All rights reserved.
10
Modbus
Modbus Serial Autobaud can be configured in either the:
•Service Port controller setup pages > Modbus tab > Modbus RS-485 > Port Configuration
or
•The WebCTRL® interface, on the Network tree, select your G5CE and go to Driver >
Communication Status > Modbus Serial
NOTE See the Modbus Integration Guide.
NOTE If you set Autobaud or make other changes in the controller setup pages, you must upload the
changes to the system database the first time you access the controller in the WebCTRL® interface.
This preserves those settings when you download memory or parameters to the controller.
To set the IP address
You must define the G5CE's IP addressing (IP address, subnet mask, and default gateway) in the
Service Port controller setup pages so that the controller can communicate with the WebCTRL Server
on the IP network. This IP addressing must match the IP addressing defined in SiteBuilder in the
controller's Properties dialog box.
Use one of the IP addressing schemes described below with the associated instructions that follow.
Use a...
If...
DHCP IP Address
generated by a DHCP server
The IP network uses a DHCP server for IP addressing
Custom Static IP Address
from your network administrator
You do not use a DHCP server and the answer to any of the
following questions is yes. Will the WebCTRL® system:
•Share a facility's existing IP data network?
•Have 254 or more devices with static IP addresses?
•Be connected to the Internet?
•Have at least one device located on the other side of an
IP router?
•Have any third-party IP devices?
Default IP Address
that your system creates
The answer to all of the above questions is no.
NOTE Carefully plan your addressing scheme to avoid duplicating addresses. If third-party devices are
integrated into the system, make sure your addresses do not conflict with their addresses.
To set a DHCP IP address
1 On the controller setup Modstat tab, find the controller’s Ethernet MAC address and write it down.
2 On the Ports tab under IP Port, select DHCP.
3 Click Save.
4 Write down the IP Address.
5 Give the DHCP network administrator the IP address and Ethernet MAC address and ask him to
reserve that IP address for the controller so that it always receives the same IP address from the
DHCP server.

Rev. 6/9/2022 All rights reserved.
11
To set a custom IP address
1 Obtain the IP address, subnet mask, and default gateway address for the controller from the facility
network administrator.
2 On the controller setup Ports tab under IP Port, select Custom Static.
3 Enter the IP Address, Subnet Mask, and Default Gateway addresses that the network
administrator gave you.
4 Click Save.
To set a default IP address
Default IP addressing assigns the following to the controller:
•IP address = 192.168.168.x
where x is the setting on the rotary switches in the range from 1 to 253
•Subnet Mask = 255.255.255.0
•Default Gateway = 192.168.168.254
1 Set the controller's three rotary switches to a unique address on the network. Set the left rotary
switch to the hundreds digit, the middle switch to the tens digit, and the right switch to the ones
digit.
EXAMPLE The switches below are set to 125.
2 On the controller setup Ports tab under IP Port, select Default IP Address.
3 Click Save.
CAUTIONS
•If you are using Port S1, the rotary switches also determine that network's address. Although the
ARCNET address range is 1 to 255, the Default IP address range is 1 to 253. Setting the rotary
switches to 0 will set the Default IP address to 1. Setting the switches to 255 will set the Default IP
to 253. Do not set the switches to 254.
•If you set the Default IP address on the controller setup Ports tab and then change the rotary
switches, you must do one of the following to correct the IP address in the controller:
○Go to the controller setup Ports tab and click the Update IP Address.
○Cycle the controller's power.
You will then need to correct the IP address in SiteBuilder.
NOTE The default address is an intranet address. Data packets from this address are not routable to
the Internet.

Rev. 6/9/2022 All rights reserved.
12
To set the Port S1 address and baud rate
The address should be in one of the following ranges based on the port's use.
•For ARCNET, the range is 1 to 255.
•For MS/TP, the range is 0 to 127.
•For Modbus, the range is 1 to 247.
You set this address on the G5CE's three rotary switches. Set the left rotary switch to the hundreds
digit, the middle switch to the tens digit, and the right switch to the ones digit.
EXAMPLE The switches below are set to 125.
CAUTION If you are using a Default IP address, the rotary switches also determine the IP address.
For MS/TP, set up autobaud or the port's baud rate
1 On the controller setup BACnet tab under Port S1, select the MSTP Baud Rate or select Yes for
MSTP Autobaud. The default is 76,800 bps.

NOTE If your system has controllers on different IP subnets separated by an IP router, you must
configure one controller on each subnet as a BACnet Broadcast Management Device (BBMD). Do not
configure more than one BBMD per subnet as this may cause circular routes. See "Setting up BACnet
Broadcast Management Devices (BBMDs)" in SiteBuilder or WebCTRL® Help.
To wire to a BACnet/ARCNET network
1 Turn off the G5CE's power.
2 Check the communications wiring for shorts and grounds.
3 Connect the communications wiring to Port S1’s screw terminals labeled Net +, Net -, and Shield.
NOTE Use the same polarity throughout the network segment.
4 If the controller has a Port S1 Configuration rotary switch, set it to 2.
5 If the G5CE is at either end of a network segment, set the port's End of Net? switch to Yes.
NOTE The controller’s End of Net switch applies network termination and bias. If the controller is at
the end of a network segment that includes a DIAG485 that has its Bias jumper in the ON position,
set the End of Net? switch to No and connect a 120 ohm termination resistor to the Net+ and Net-
terminals. See DIAG485 Technical Instructions for more information.
6 Turn on the controller's power.
7 To verify communication with the network, get a Module Status report in the WebCTRL® interface
for a controller on the ARCNET network.
NOTE This step requires that you have set up the router in SiteBuilder and downloaded it from the
WebCTRL® interface.
To wire to a BACnet MS/TP network
An MS/TP network can be wired to either Port S1 or Port S2.
1 Turn off the G5CE's power.
2 Check the communications wiring for shorts and grounds.
3 Connect the communications wiring to the Port S1 or Port S2 screw terminals labeled Net +, Net -,
and Shield.
NOTE Use the same polarity throughout the network segment.
4 If you are using Port S1, and the controller has a Port S1 Configuration rotary switch, set it to 1.
NOTE If Port S1 is not being used for any network, set this rotary switch to 0.
5 If the G5CE is at either end of a network segment, set the port's End of Net? switch to Yes.
NOTE The controller’s End of Net switch applies network termination and bias. If the controller is at
the end of a network segment that includes a DIAG485 that has its Bias jumper in the ON position,
set the End of Net? switch to No and connect a 120 ohm termination resistor to the Net+ and Net-
terminals. See DIAG485 Technical Instructions for more information.
6 Turn on the controller's power.
7 To verify communication with the network, get a Module Status report in the WebCTRL® interface
for a controller on the MS/TP network.
NOTE This step requires that you have set up the router in SiteBuilder and downloaded it from the
WebCTRL® interface.
