INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. Check out the product after installation, as provided in
the Q7700 Network Interface Unit instructions,
form 63-2278.
5. Make sure that repairs are made only by the
manufacturer.
6. If trouble develops, disconnect the equipment from the
modem and determine the cause of the fault.
Reconnect only when the problem is corrected.
CAUTION
1. Disconnect power supply before beginning
installation to prevent electrical shock and
equipment damage. More than one power supply
disconnection can be involved.
2. Wiring must comply with all applicable codes,
ordinances and regulations.
3. Refer to Fig. 6 for proper system wiring.
4. Do not plug or unplug any Network Interface Unit
ControlBus™ Module or electrical connectors
with the power on. Make sure that power is off to
protect against equipment damage.
Humidity
Install the Network Interface Unit where the relative humidity
never reaches the saturation point. The Network Interface
Unit is designed to operate in an 85 percent relative humidity
continuous noncondensing moisture environment.
Condensing moisture can result in improper operation.
Vibration
Do not install the Network Interface Unit where it can be
subjected to excessive vibration in excess of 0.5G
continuous maximum vibration.
Weather
The Network Interface Unit is not designed to be weather
tight. If installed outdoors, the Network Interface Unit must be
protected.

WIRING
Wiring Requirements
1. All wiring must comply with all applicable electrical
codes, ordinances, and regulations.
2. Recommended wire size and type for ControlBus™
communication; terminal identification numbers are
noted within brackets:
1 [A]
2 [B]
3 [C]

SYSNet™ QS7700A NETWORK INTERFACE ControlBus™ MODULE
3. Recommended wiring for ControlBus™ Module for
communications routing purposes is unshielded 22 AWG,
two-wire twisted cable and one wire for ground, if the
leadwire run and noise conditions permit. If necessary,
Belden 8771 shielded cable or equivalent can be used.
Be aware that the BCS7700 chassis module must be at
one end of the daisy chain and the module on the
farthest end of the daisy chain configuration string require
a 120 ohm, 1/4 watt (minimum) resistor termination
across terminals 1 and 2 of the electrical connectors.
See Fig. 6.
a. Do not route the ControlBus™ cable in conduit
with line voltage circuits.
b. Do not route the ControlBus™ cable close to the
ignition transformer.
c. Route the ControlBus™ cable outside of conduit
if properly supported and protected from damage.
d. Route the ControlBus™ cable so that all devices
are connected in a daisychain(A-A, B-B, C-C).
The BCS 7700 Chassis Module must be at one
end of the daisy chain configuration string. The
interconnection of all other devices is not
important, except that the device at the distant
end of the daisy chain configuration string must
be terminated with a 120 ohm, 1/4 watt resistor
between terminals A and B.
4. Maximum wire lengths can be 4000 ft (1219m) for the
ControlBus™ RS-485 interface under ideal conditions.
Procedure
Refer to Fig. 6 for proper wiring.
Be sure that power is removed from the control panel
by opening the main disconnect before beginning wiring
to the electrical connectors. More than one
disconnection can be involved.
Select the location of the Network Interface Unit to be
mounted:
a. Near a phone line.
b. Within 4000 ft (1219m) of all BCS 7700s that will
be connected to the Network Interface Unit.
c. Within 50 ft (15m) of the personal computer that
will be connected to the 25-pin RS-232 port of the

RS-232 connector of the Network Interface Unit
(see Fig 4).
쐈 Connect the serial port of the personal computer to the
25-pin RS-232C port on the Network Interface Unit for
local personal computer application, see Fig. 3.
쐉 Do not exceed 600 mA current draw, six card
maximum, total capacity of the plug-in cards. Refer to
the ControlBus™ Module device label and this
specification for individual loads.
