About the InfiLink 200
Without the InfiLink 200, the maximum cable length for all arms on
Infinet is 4,000 ft. at 19,200 baud (up to 32 local controllers). The InfiLink 200 amplification module lets you extend Infinet beyond 4,000
ft. or have more than 32 local controllers.
It is also an active hub that can connect up to 127 local controllers to the
Infinet in a star configuration.
Before you can install the InfiLink 200, you need to know some basic
information about it: its dimensions and enclosure, power requirements,
grounding requirements, and environmental requirements.
Note
This equipment generates, uses, and can radiate radio frequency energy
and if not installed and used in accordance with the instruction manual
may cause interference to radio communications. It has been tested and
found to comply with the limits for a Class A computing device
pursuant to Subpart J of Part 15 of the FCC Rules, which are designed
to provide reasonable protection against such interference when
operated in a commercial environment. Operation of this equipment in
a residential area is likely to cause interference in which case the user
at his own expense will be required to take whatever measures may be
required to correct the interference.
InfiLink 200 Dimensions
Each InfiLink 200 is 8.5 × 7.5 × 2.75 in. The unit is inside a hinged
aluminum enclosure that meets UL standards.

Power Requirements
Warning
Be sure your installation complies with local, state, and national
electrical codes.
Caution
The InfiLink 200 should receive power from its own independent,
unswitched circuit.
InfiLink 200 requires 120 V +10/–15%, 60 Hz. You can select 230
VAC, 50 Hz for European sites by setting two jumpers, but for smoke
control applications, you must use 120 VAC +10/–15%, 60 Hz.
You select the input voltage. When you receive it, it is set to 120 V.
Instructions for altering the input voltage are included later in this
manual.
Building Ground Requirements
Warning
Be sure that all hardware from Andover Controls Corporation is
grounded to true earth ground. This kind of ground protects the
equipment from lightning strikes and other power surges in the area.

We cannot guarantee that the control system will operate as
documented unless you properly ground all controllers.

InfiLink 200 Installation Guide
Warning
Be sure to have your grounds inspected before you begin the
installation process to be sure your municipality follows the National
Electrical Code. Many municipalities do not and often have
substandard electrical grounds.
An example of a substandard ground is a galvanized steel cold water
pipe. As the pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator, raising the potential of the pipe with respect to
the ground.
When lightning strikes in the area of the installation, it drastically
changes the potential of the earth.
Surges of much lower potential also impact the reliability of Andover
Controls equipment.
Since properly grounded Andover Controls units respond to changes in
potential more rapidly than poorly grounded electrical systems, a poorly grounded building tries to reach ground through the Andover
Controls system. The surge of current can destroy electronic components on the controller board.

Inspecting the Ground
You can check your ground as follows:
1. Check your ground by first inspecting the building power
distribution panel for earth ground termination. If the ground
termination is any of the following, it is not adequate and must be
corrected:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire (smaller than 14 AWG).
2. Be sure your InfiLink 200 is connected to the ground with a copper
conductor that terminates at the distribution panel.
Environmental Requirements
The InfiLink 200 operates in rooms with temperatures ranging from 32
to 120° F and with humidity up to 85%, non-condensing.

1. Disconnect the jumper end from E2 and move it to E3 so it jumpers
TP2 to E3.
2. Disconnect the jumper end from E1 to E3 and entirely remove it
from the controller board.
Connecting the AC Power
Warning
Be sure the AC power is not connected to an electrical power source
while you are wiring the controller, or you could receive an electrical
shock that is life-threatening.
The AC power connection is in the lower left corner of the InfiLink 200.
You must wire the AC cable to the three screws on the far left.

Wiring the Infinet to the 9000 Controller
You connect the first piece of Infinet cabling from the 9000 controller
to the InfiLink 200. Port 1, labeled INPUT, is where the connection to
the 9000 controller, 9500, or previous InfiLink 200 comes in to the link.
(See the appropriate hardware installation guide for how to connect Infinet at that end.)
Caution
You must have Port 1 connected to a 9000 controller, 9500, or other
InfiLink 200 to ensure proper shielding of the entire link.
The shield for Port 1 is not connected to earth ground on the board, but
the shields for Ports 2 through 5 are connected to earth ground. Port 1,
however, is wired the same way as the others, covered in the next
section.
Wiring the Infinet to the InfiLink 200
Figure 4 illustrates how to wire the Infinet cables to the removable
block terminal connectors for Ports 1 through 5 on the left side of the
InfiLink 200.
Note
You must use shielded cables for Infinet to ensure compliance with the
Class A FCC limits and to ensure reliable communications.

Proceed as follows:
1. Trim back the shield over the wires.
2. Take the first wire for the Infinet and slip it in the hole beneath the
screw labeled with a plus sign (top).
3. Tighten the screw down on it until the screw holds the wire in place.
4. Slip the second (usually black) wire from the Infinet cable under the
screw labeled with a minus sign (middle) and tighten the screw
down on it.
5. Slip the shields under the screw labeled SHLD (bottom) and tighten
the screw down on it.
6. Tighten the screw down on it until the screw holds the shield in
place. This shield is connected to earth ground.
7. Wire the other end of the cable to the first Infinet controller on that
arm of the star.
Setting the Baud Rate
You set the baud rate using the rotary switch to the upper right on the
front of InfiLink 200. The baud rate should match the rate of the rest of
the network. We recommend 19.2K baud.
Understanding the LEDs
Notice that six green and six yellow lights are on the front of the box.
The top pair (green and yellow) of lights corresponds to the RS-232 port
14
Technical Manuals Online! - http://www.tech-man.com
InfiLink 200 Installation Guide
above it and each of the other five corresponds to an arm of the star of
Infinet cables extending to and from the InfiLink 200.
The yellow lights indicate data is being transmitted down the RS-232
port or the corresponding arm of the Infinet.
The green lights indicate data is being received from the RS-232 port or
the corresponding arm of the Infinet.
Attaching a Modem to InfiLink 200
You can connect two buildings with the Infinet by having modems attached to InfiLink 200s in each building.
Before you can use special modems to connect Infinet, you must have a
conditioned, clean, dedicated telephone line installed. Contact your
telephone company to install the line.
To connect the modem to the InfiLink 200, connect the RS-232 cable on
the modem to the RS-232 port on the top center of the link.
Follow the modem instructions to set it to the correct mode. Be sure the
baud rates of the InfiLink 200 and modem match the entire network.

Powering Up the InfiLink 200
Connect the AC power cable to an electrical power source and the
InfiLink 200 starts automatically. The following occurs:
1. The red power light to the right and vertical center of the InfiLink
200 comes on.
2. The yellow TD light of any given pair immediately flashes when
data is being transmitted to that particular Infinet port.
3. The green RD light of any given pair immediately flashes when data
is being received from the corresponding branches of Infinet. This
may not happen immediately.
