a. Near a phone line.
b. Within 4000 ft (1219 m) of all Relay Modules 

connected to the Network Interface Unit.

c. Within 50 ft (15 m) of the personal computer 

connected to the 25-pin RS-232 port of the Network 
Interface Unit.

4.

Mount the Network Interface Unit and insert the 
ControlBus™ Module into the Network Interface Unit 
slot, see Fig. 2 and 5.

•

Route the ControlBus™ cable so that all devices are 
connected in a daisy chain configuration. It is 
recommended that the QS7800B ControlBus™ Module be 
at one end of the daisy chain.

5.

Connect L1, L2 and Ground (GND) to the pigtails 
(Q7700A only).

6.

Insert the plug-in cards into the open slots of the 
Network Interface Unit, starting with slot one.

7.

Install the covers, power wiring compartment and 
Network Interface Unit. 

8.

Connect the serial port of the modem to the 9-pin 
RS-232 connector of the Network Interface Unit (see 
Fig 4).

9.

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.

10.

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.

11.

Recheck all wiring with Fig. 6.

12.
