Safety Precautions
The following items are warnings of a general nature relating to the installation and start-up of the JACE-6
controller. Be sure to heed these warnings to prevent personal injury or equipment damage.
Warning • Depending on power module used, the circuit powering the JACE-6 is 90–263Vac at 50/60 Hz
(ifusing NPB-PWR-UN), 24Vacat50/60 Hz or 24Vdc(ifusingNPB-PWR), or from100–240Vac
at 50/60 Hz (if using NPB-WPM-XXX). Disconnect power before installation or servicing to
prevent electrical shock or equipment damage.
•Make all connections in accordance with national and local electrical codes. Use copper
conductors only.
•To reduce the risk of fire or electrical shock, install in a controlled environment relatively free
of contaminants.
•This device is only intended for use as a monitoring and control device. To prevent data loss or
equipment damage, do not use it for any other purpose.
Static Discharge Precautions
Static charges produce voltages high enough to damage electronic components. The microprocessors and
associated circuitry within a JACE-6 controller are sensitive to static discharge. Follow these precautions when
installing, servicing, or operating the system:
Caution • Work in a static-free area.
•Discharge any static electricity you may have accumulated. Discharge static electricity by
touching a known, securely grounded object.
• Do not handle the printed circuit board (PCB)without proper protection against static discharge.
Use a wrist strap when handling PCBs. The wrist strap clamp must be secured to earth ground.

Mounting
Mount the JACE-6 controller in a location that allows clearance for wiring, servicing, and module removal.
Additional mounting information applies, as follows:
•Environmental Requirements
•Physical Mounting
Environmental Requirements
Note the following requirements for the JACE-6 mounting location:
•This product is intended for indoor use only. Do not expose the unit to ambient conditions outside of the
range of 0ºC (32º F) to 50ºC (122º F) and relative humidity outside the range 5% to 95% non-condensing
(pollution degree 1).
•If mounting inside an enclosure, that enclosure should be designed to keep the unit within its required
operating range considering a 20-watt dissipation by the controller, plus dissipation from any other
devices installed in the same enclosure. This is especially important if the controller is mounted inside an
enclosure with other heat producing equipment.
•Do not mount the unit:
– in an area where excessive moisture, corrosive fumes, or explosive vapors are present.
– where vibration or shock is likely to occur.
– in a location subject to electrical noise. This includes the proximity of large electrical contractors,
electrical machinery, welding equipment, spark igniters, and variable frequency drives.
Physical Mounting
The following information applies about physically mounting the unit.
•You can mount the JACE-6 in any orientation. It it not necessary to remove the cover before mounting.
•Mounting on a 35mm wide DIN rail is recommended. The JACE-6 unit base has a molded DIN rail slot
and locking clip, as do the power modules (NPB-PWR, NPB-PWR-UN) and both types of I/O expansion
modules. Mounting on a DIN rail ensures accurate alignment of connectors between all modules.
•If DIN rail mounting is impractical, you can use screws in mounting tabs on the JACE-6, then in any
end-connected accessory (NPB-PWR, etc.). Tab dimensions are on the last page of this document.
The following procedure provides step-by-step DIN rail mounting instructions for the JACE-6.
Note Mount the JACE-6 prior to mounting any accessory items (24V power module, I/O modules).
Procedure 1 To mount on DIN rail
Step 1 Securely install the DIN rail using at least two screws, near both ends of the rail.
Step 2 Position the JACE-6 on the rail, tilting to hook DIN rail tabs over one edge of the DIN rail (Figure 1).
Step 3 Use a screwdriver to pry down the plastic locking clip, and push down and in on the JACE-6, to force
the locking clip to snap over the other edge of the DIN rail.
Step 4 Mount any accessory item (NPB-PWR, I/O module) onto the DIN rail in the same manner.
Step 5 Slide the accessory along the DIN rail to connect its 20-position plug into the JACE-6.

base board. Hand tighten these screws.
Step 10 Replace the cover.
About Accessory Modules
The JACE-6 has a 20-pin, right-angle, Euro-DIN connector that accepts custom-built accessory modules. The
connector provides power and signal lines to any connected modules, and is located on the end of the JACE-6
opposite to the option cards.
Warning • Power to the JACE-6 must be OFF when inserting or unplugging accessory modules.
Wait for all LED activity to stop (all LEDs to be off).
•Also, do not connect live voltages to the inputs or outputs of an I/O module (IO-16 or IO-34)
while it is in an “un-powered state” before plugging the module into a JACE-6.
Otherwise, damage to the I/O module and/or the JACE-6 controller may result!
Each accessory module has a DIN-mount base, and typically provides two (2) 20-pin connectors that allow you
to “chain” multiple accessories (see Procedure 1 on page 4). Table 2 lists the currently available modules.

Power Wiring
The JACE-6 must be powered by an approved 15 Vdc power source. This can be either1an external wall mount
AC adapter (WPM-XXX), a DIN-mount 24Vac/dc-powered module (NPB-PWR), or a DIN-mount line
line-powered (90–263 Vac) module (NPB-PWR-UN).
The JACE-6 controller does not include an on/off switch. To apply power, you either:
•if WPM-XXX, plug in the power connector to the JACE-6.
•if NPB-PWR, plug in its 2-position power connector.
•if NPB-PWR-UN, energize the AC circuit (90–263 Vac) wired to that module.
Caution Do not connect both the WPM-XXX and NPB-PWR / NPB-PWR-UN supplies at the same time, or
equipment damage may result.
If desired, you can use the wall mount WPM-XXX in your office (to initially commission the JACE-6), and then
install the JACE-6 at the job using either an NPB-PWR or NPB-PWR-UN module. The following sections
provide more details:
•WPM-XXX (Wall Power Modules)
•NPB-PWR (24Vac/dc-powered in-line module)
•NPB-PWR-UN (Universal 90V–263Vac-powered in-line module)
WPM-XXX
All models of wall power modules (US, EUR, UK, JA) are self-contained, isolated, switching power supplies
designed to plug into a standard building power receptacle of appropriate voltage. To supply power to the
JACE-6, you then simply plug the barrel connector plug from the WPM-XXX into the barrel power connector
on the JACE-6 base board (see Figure 5 on page 13).
Caution Do not plug the barrel connector plug from the WPM-XXX into the JACE-6 untilall other mounting
and wiring is completed. See “Power Up and Initial Checkout,” page 15.
NPB-PWR
Using the NPB-PWR module lets you power the JACE-6 (and if installed, IO-16 modules) from a dedicated
Class 2, 24Vac transformer, or from a 24Vdc power supply. If installing IO-16 modules, the NPB-PWR installs
as the last (end) module in the chain. See Figure 1 on page 5.
1. In some markets, a fourth power option is available: an IO-34 accessory module, which is a combination of the
NPB-PWR module and two IO-16 modules (plus two extra relays). Please refer to its mounting and wiring instructions
document for more details. For general information on accessory modules, see “About Accessory Modules,” page 8.

Part Number 10821 Published: April 19, 2007 13
Note Prior to connecting cables, provide strain relief for them to prevent damage to the controller.
Figure 5 JACE-6 bottom side (cover removed).
Ethernet
Two, female 10/100-Mbit Ethernet connections are provided on the JACE-6. These are RJ-45 connectors
labeled LAN2 and LAN1. Use a standard Ethernet patch cable for connecting to a hub or Ethernet switch. An
activity LED for each Ethernet port is visible, and are labeled “LAN2” and “LAN1” on the cover.
The factory-default IP address for LAN1 on a JACE-6 is 192.168.1.12n, where the last numeral nin the
address matches the JACE-6’s serial number, and subnet mask is 255.255.255.0. By default, LAN2 on a
JACE-6 is disabled. Refer to the JACE NiagaraAX Install and Startup Guide for details on changing IP address.
Note Typically, you only use LAN1 (primary port), unless you have a specific application for isolating a
driver’s network traffic to a separate LAN, using LAN2. Do not use LAN2 as the primary port.
Serial
There are two serial ports on the JACE-6 base board. Each has a UART capable of operation up to 115,200 baud.
At the bottom of the board (see Figure 5), the left port is an RS-232 port using an DB-9 plug (male) connector.
To the right of this is a two-wire with shield, isolated RS-485 port, using a screw-terminal connector plug. In
addition, on the top board (to the right) is a third, standard USB port.
Note A green “receive” LED and yellow “transmit” LED are provided for each serial port. These LEDs are
located on the bottom board, on the opposite side of the serial connectors (see Figure 2 on page 6).
These LEDs are labeled on the board (COM1, COM2) and are not visible with the cover on.
RS-232—An RS-232 serial port using a male DB-9 connector always operates as COM1. You can use standard
DB-9 serial cables with this port. The JACE-6 is a serial DTE device, such another DTE device (PC, for
example) requires a “null modem” cable. If connecting the JACE-6 to a DCE device (modem, for example), a
straight-through cable is used. Table 3 provides standard serial DB-9 pinouts.

Following all mounting and wiring, perform the following:
Procedure 4 Initial power up and checkout
Step 1 Connect the Backup Battery.
Step 2 Apply Power.
Step 3 Check the Status LEDs.
Connect the Backup Battery
With the cover removed from the JACE-6 (see “Removing and Replacing the Cover,” page 6), locate the red
and black wires coming from the backup battery, with 2-position connector plug. Insert the plug into the battery
connector on the bottom board (below option slot 2 area), as shown in Figure 6.
Figure 6 Backup battery connector on JACE-6 bottom board.
The connector is keyed—you cannot insert it incorrectly. The red (positive) connection should be the furthest
from the two 30-pin option board connectors. For more battery details, see “About the Battery,” page 16.
Apply Power
Apply power to the JACE-6 by plugging in the power plug into either the JACE-6 (if wall mount AC adapter
WPM-XXX) or the 24V-powered NPB-PWR module. If powering using the line-voltage input NPM-PWR-UN
power supply module, energize the 90–263 Vac circuit wired to the NPB-PWR-UN module.
Caution Do not connect both the WPM-XXX and NPB-PWR / NPB-PWR-UN supplies at the same time, or
equipment damage may result, or a power outage may go unrecognized.

Check the Status LEDs
16
Check the Status LEDs
When power is applied, the green LED labeled “STATUS” will light. This indicates that the system is OK and
that power is applied. Once the JACE-6 boots, the yellow “BEAT” (heartbeat) LED will begin blinking, with a
typical rate of about 1 Hz. Blinking should begin within 30 seconds after power is applied.
If after applying power, the STATUS LED goes out, or if the BEAT LED comes on (steady) and stays lit longer
than two minutes, contact Systems Engineering for technical assistance. See also the “Using Status LEDs”
section on page 17.
About the Battery
The JACE-6 is provided with a custom 10-cell NiMH battery pack mounted to the unit (under the cover). This
battery allows the JACE to continue operation through very short power bumps (a few seconds in duration). If
a longer power outage occurs, the battery provides enough run time for the JACE-6 to backup data and then
shutdown. Typically, this is one minute. Shutdown occurs automatically, after data is backed up to on-board
flash memory.
The JACE-6 charges the battery during normal operation, until fully charged. Typically, the charge operation
completes within 18 hours. Following a power outage, the battery is charged again, as necessary. The power and
battery circuitry is monitored by a station running on the JACE (via the PowerMonitorService). Station alarms
are generated whenever primary power is lost, or if the battery is unchargedor unable to hold a sufficient charge.
The battery should be replaced approximately every three years, or more often if the unit is in a high temperature
environment.
Note A NiMH battery characteristic is to lose charge if not left in charge mode (trickle charge). Leaving the
battery unconnected, or in the unit powered off will cause the battery to fully discharge in a matter of
weeks. Note that in the case of a new JACE-6, it ships from the factory with a completely discharged
battery. Therefore, allow at least 18 hours for the battery to charge if it has not been in a powered unit.
For more information on the use and replacement of the battery, refer to the “Required Battery Maintenance”
section on page 18.

Using Status LEDs Ethernet Ports
JACE-6 Mounting and Wiring Instructions
Part Number 10821 Published: April 19, 2007 17
Using Status LEDs
The JACE-6 controller includes several LEDs that can help determine the status of the unit. They are located in
two places: the top of the controller (visible through the cover), and for serial ports, on the bottom board (only
with cover removed). From left-to-right these LEDs include:
•Ethernet Ports
•Heartbeat
•Status
•Serial Ports
Refer to Figure 2 on page 6 for the exact locations of status LEDs on the JACE-6 controller.
Ethernet Ports
Each Ethernet port (“LAN2”, “LAN1”) has one green LED, visible on the top cover.
A “LANx” LED indicates activity on that port as follows:
•Off—No Ethernet link is made
•On—Ethernet link is present, but no activity on the LAN
•Blinking—Ethernet link is present with data activity on the LAN.
Heartbeat
The “BEAT” LED is located to the right of the Ethernet status LEDs, and is yellow. Under normal operation,
this LED should blink about once per second. If the heartbeat LED stays on constantly, does not light, or blinks
very fast (more than once per second), contact System Engineering for technical support.
Caution During boot-up, the heartbeat LED blinks in a 90% on — 10% off pattern. Do not remove power
during this time, or data loss may result (I/O module’s firmware upgrade may be in progress).
Status
The “STATUS” LED is located to the right of the heartbeat (“BEAT”) LED, and is green. This LED provides a
CPU machine status check, and should remain lit whenever the JACE-6 is powered. If the STATUS LED does
not light while power is applied, contact System Engineering for technical support.
Serial Ports
LEDs for the two serial ports are located on the JACE-6’s bottom board, on the opposite side of the RS-232 and
RS-485 ports (see Figure 2 on page 6). Labels “COM1” and “COM2” correspond to the software configuration
of the COM ports. LEDs show the transmit and receive activity for the serial ports and optional modem.
Note You must remove the cover to the serial port LEDs. See “Removing and Replacing the Cover,” page 6.
•The yellow transmit LED indicates that the JACE-6 is sending data out the serial port over a
communications line to a connected device.
•The green receive LED indicates that the JACE-6 is receiving data from a connected device.
These LEDs provide a fixed on-time when data is detected on the port. If the receive LED is on constantly, this
indicates a problem with the communications channel, such as a shorted wire or reversed wiring.

Maintaining the JACE-6
This section provides information on the following topics:
•Cleaning
•Required Battery Maintenance
•Replacement Parts
•Replacing the JACE-6 base assembly
•Returning a Defective Unit
Cleaning
If dust or metal filings are present inside the unit, clean with vacuum or compressed air. Otherwise, no cleaning
inside the unit is required. Optionally, if the cover becomes dirty, you can wipe it with a damp cloth and mild
detergent.
Required Battery Maintenance
Battery life expectancy is a function of its discharge cycles (the number of discharges and their depth) and the
ambient temperature of the battery during normal operation. In most applications, the battery should see
relatively few discharges. Therefore, ambient temperature has more to do with determining the life expectancy
of the battery than does any other factor. If the JACE-6 is installed in a conditioned space, the battery should
provide dependable service for approximately three years (average). In an environment where the operating
temperature is higher (that is, 50ºC or 122ºF), you should only expect the battery to last approximately one year.
The NiMH battery in the JACE-6 controller is fully discharged when factory shipped. Additionally, NiMH
batteries lose charge over time if not kept trickle-charged (for more details, see “About the Battery,” page 16).
Therefore, even a new unit (or replacement battery) will require up to 18 hours of powered operation before it
can provide reliable backup power (is at full charge).
The JACE-6 monitors the battery and periodically loads the battery to test its ability to maintain battery-backed
functions. Investigate any battery trouble message, and check the battery connections to the unit. Replace the
battery as required. To order a new battery, see the “Standard Replacement Parts” section on page 19.
Replacing the Battery
The replacement NPB-BATT battery is a complete assembly, that is a custom NiMH battery pack pre-attached
to a battery bracket. See Figure 6 on page 15.
Caution Use only NiMH battery packs approved for use with the JACE-6.
To replace the battery, proceed as follows:
Procedure 5 Replacing NiMH battery assembly on a JACE-6.
Step 1 Backup the JACE-6 controller’s configuration to your PC using the appropriate NiagaraAX software
tool (for example, Workbench).
Step 2 Remove power from the JACE-6.
Wait for LED activity to stop—after several seconds, all LEDs on the JACE-6 should be off.
Step 3 Remove the cover. See “Removing and Replacing the Cover,” page 6.

Step 4 Remove the old battery and bracket assembly by taking out the four screws holding it in place, setting
the screws aside for later. Unplug the battery from the connector on the JACE-6.
Step 5 Plug the battery connector plug of the replacement battery into the battery connector on the JACE-6.
Step 6 Set the replacement battery/bracket assembly back over the option card slots, with the mounting holes
aligned with the standoffs.
Step 7 Place the four screws through the battery bracket, option card blanking plates, option cards (if any),
and into the standoffs on the JACE-6 base board. Using a screwdriver, hand tighten these screws.
Step 8 Replace the cover.
Step 9 Restore power to the JACE-6 and verify normal operation.
Replacement Parts
Servicing the JACE-6 may call for replacement parts. There are three categories of parts:
•Non-replaceable Parts
•Standard Replacement Parts
•New Replacement Units
Non-replaceable Parts
Other than the parts listed in the replacement parts sections, there are no serviceable components on the base
assembly.
Memory
Any addition, modification, or replacement of memory components requires software configuration and is not
a field upgrade. For additional information on modifying the memory capacity of the JACE-6, consult your
regional Tridium office.
Fuse
The JACE-6 contains a non-user replaceable fuse, soldered on the circuit board. This fuse provides protection
from internal shorts or connection to incorrect power supplies. If the fuse circuitry is suspect, contact your
regional Tridium office for technical support. See the “Returning a Defective Unit” section on page 21.
Standard Replacement Parts
Standard replacement parts are listed in Table 4 and can be ordered from stock without restriction. Standard
replacement parts cannot be returned for credit and should be disposed of in an appropriate manner.
Note Screws used for the JACE-6 are standard #6-32 x3/8" types, which you can obtain locally if lost.

New Replacement Units
To replace a faulty unit, order and install a new JACE-6—please note that JACE-6 series products do not have
special “field replacement units,” or FRUs, with separate part numbers.
If the faulty JACE-6 is still in warranty, you can receive credit by returning it to Tridium. Be sure to contact
Tridium for a return authorization (RA) number before shipping an item for return credit. See “Returning a
Defective Unit,” page 21, for more details.
Note Before ordering a new JACE-6, it is strongly recommended that you contact your normal technical
support resource to eliminate the possibility of a software issue or mis-configuration problem.
Replacing the JACE-6 base assembly
Caution Before handling circuit boards, discharge any accumulated static by touching the metal surface of
the JACE-6. For details, see the “Static Discharge Precautions” section on page 3.
To replace the JACE-6 base assembly in the field, proceed as follows:
Procedure 6 Replacing a JACE-6 base assembly.
Step 1 Using the appropriate NiagaraAX software tool, back up the JACE-6’s configuration to your PC.
Step 2 Remove power to the JACE-6. The unit should power down automatically.
Note If IO accessory modules are installed, and any I/O points have voltage, turn the devices off or
disconnect power to them.
Step 3 Note positions of all communications and other wiring cables going to the JACE-6, as well as all
installed accessory modules (if they must be removed). If necessary, label connectors and accessory
modules to avoid mis-connection later, after JACE-6 is replaced.
Step 4 Unplug all Ethernet, serial, LON, modem, and I/O connectors from the JACE-6, and unplug its earth
ground wire.
Step 5 If IO accessory modules are installed:
– If DIN rail mounting with DIN end-clips was used, you may be able to remove the DIN rail end clip
that secures the JACE-6 end of the assembly, and then slide the JACE-6 away from the rest of the
assembly. Then you can remove the JACE-6 from the DIN rail (see Figure 1 on page 5), leaving the
mounting and wiring of IO modules untouched.
In this case, after removing the JACE-6 from the DIN rail, skip ahead to Step 6.
– If tab (screw) mounting was used instead of DIN rail mounting, or if a combination of DIN rail
mounting and tab screws (into the JACE-6’s “accessory side” tab holes, see last page), you will need
to remove the accessory modules first, before removing the JACE-6.
In this case:
a. Making a careful note or all wiring terminations, unplug the I/O connector plugs and earth ground
wires from the installed IO modules.
