NOTE: Horizontal mounting is strongly recommend-
ed, to achieve maximum heat dissipation and meet the
operating temperature upper limit. Any other mounting
orientation reduces this upper limit.
Mounting On DIN Rail, see images
Pull the controller's locking clip down.
1
Tilt the controller to hook over the DIN rail.
2
Push down and in on the unit to fasten to the rail.
3
Push the locking clip up to secure.
4
Mount any option module onto the DIN rail in the
5
same way. Slide the module firmly into the control-
ler's connector to seat.
Repeat for other modules as needed (4 maximum).
6
Carefully secure both ends of the final assembly with
7
DIN rail end-clips provided by the DIN rail vendor.
Wiring
Communications Wiring, see image
Field communications ports are as follows:
RS485 ports and bias switches.
1
WLAN adapter, settings switch, and antenna.
2
Ethernet ports, 10/100-Mbit, RJ-45.
3
Earth ground and 24V power input.
4
WLAN
NOTE: WLAN is not supported for NiagaraAX
An integral WLAN adapter provides wireless connectiv-
ity using the IEEE 802.11a/b/g/n standard, and provides
an RP-SMA coax antenna connector.
The WLAN configuration switch sets operation as
follows:
• OFF - (Default, middle) WLAN adapter is disabled.
• ACC - Controller provides operation as a WLAN
access point for up to 16 clients.
• CLT - Controller operates as a client to an existing
802.11a/b/g/n router or access point.
Refer to the document JACE-8000 WiFi Guide for details
on WLAN configuration and factory-default IP settings.
RS485 Wiring, see image
On the controller's top side, two RS485 ports operate as
COM1 and COM2. Each port is capable of up to 115,200
baud, and uses a 3-position, screw terminal connector.
NOTE: IO modules, Security modules, and Smartkeys all
need to be on an RS-485 network.
Use shielded, twisted-pair, 18-22 AWG cabling to wire in
a continuous multidrop fashion to other RS485 devices:
"minus to minus", "plus to plus, " and "shield to shield. "
Connect the shield wire to earth ground at one end only.
Image shows example wiring.

RS485 port A (COM1) is often used to support a
1
trunk of T-IO-16-485 modules. NOTE: Do not mix
T-IO-16-485s with other types of RS485 devices on
the same RS485 trunk.
RS485 port B (COM2) supports a network of field
2
devices using RS485 communication. Additional
RS485 COM ports (COM3+) may be added, with
port numbering dependent on devices added to each
unique system. For example, an Enterprise Security
network includes the following:
– Access network (COM2 default)
– Smartkey, intrusion keypad (COM3 default)
– NRIO network
NOTE: RS485 devices on the same network should
3
use the same protocol and baud rate. Up to 32 or
more devices may be supported, depending on device
specifications.
RS485 bias switches
Each RS485 port has an adjacent 3-position biasing
switch. Settings of each RS485 bias switch are:
• BIA - (middle, as-shipped setting) RS485 biasing.
2.7K bias resistors with no termination resistor.
• END - RS485 biasing and a termination: 562 Ohm
bias resistors and 150 Ohm termination resistor.
• MID - RS485 biasing or termination: 47.5K bias
resistors with no termination resistor.
Often, adding RS-485 biasing can improve communica-
tions by eliminating indeterminate idle states.
See JACE-8000 Mounting and Wiring Guide for more
details on RS485 biasing. Each RS485 port has two LEDs.
See the "Status LEDs" section for more information.
Ethernet Wiring, see image
Two RJ-45 10/100-Mbit Ethernet connectors are labeled
PRI (LAN1) for primary, and SEC (LAN2) for second-
ary. Use a standard Ethernet patch cable to an Ethernet
switch.
The factory-default IP address for PRI is 192.168.1.140.
The default subnet mask is 255.255.255.0. By default, the
SEC (LAN2) port is disabled.
Refer to the JACE-8000 Install and Startup Guide for de-
tails on the software configuration of the Ethernet ports.
Earth Ground & Power
Earth grounding provides protection from electrostatic
discharge or other forms of EMI.
NOTE: Depending on power source used (image
(AC): Dedicated 24V transformer required, with
2.1
neither side of the transformer secondary tied to
ground.
(DC): Polarity is unimportant (uses onboard diode
2.2
bridge), with neither leg tied to ground.
(Wall-mount AC adapter, WPM- 8000) instead of
2.3
wiring 24V to 2-position connector.
