1. SMART COMMUNICATION UNIT
1.1 General
Described in this manual are the operating instructions to use the application software LinkTop®of the
Smart Communication Unit which operates in the Microsoft operating system Windows®environment.
LinkTop®is a communication terminal designed for use in combination with a personal computer
(hereinafter referred to as PC) and any one of the OVAL ultrasonic flowmeters to set up, alter, adjust, or
read out parameters and variables, through interactive communications, either on-site or from remote
locations.
Using a Windows®PC at hand, it is possible to monitor multiple windows on its screen.
It is necessary to install the application software LinkTop®in your PC before connecting the communica-
tion interface (*) between the PC and the flowmeter.
NOTE: In case of Bell202 communication: Bell202 communication interface of OVAL smart
communication unit EL2310 is necessary.
2. BEFORE YOU BEGIN
2.1 Inspection upon Receipt
Be sure you have the following items.

The receiving instrument in this figure requires a load resistance 250
Ωmin. Its upper limit depends on the
specification of the transmitter in use.
If the receiving instrument does not have a built-in RL, an external RLneeds to be connected in series.
