Serial Communications

Multi-Point Wiring

The standard point-to-point wiring configuration for the serial
interface converter may be modified to permit the use of a multi-point
wiring arrangement. In a multi-point RS485 system, one flowmeter
(the master) is connected to the personal computer, while a number of
additional flowmeters (the slaves) are chained together and connected
to the master flowmeter. In order to implement such a system, the

DIP

switch settings inside each serial interface converter must be changed.

IMPORTANT:

The serial interface converter in the last slave unit in
the chain should not be reconfigured.

Reconfiguring a Serial
Interface Converter

To reconfigure a serial interface converter for multi-point wiring,
complete the following steps:

1.

Disconnect the

main power

to the electronics console and open the

cover.

!WARNING!

Dangerous voltages exist within the electronics console.

Do not perform any wiring operations until the main

power to the unit has been disconnected.

2.

Remove the clear plastic

shroud

that covers the electrical

connectors.

3.

Remove the serial interface converter

mounting bracket

by

removing the standoff located just below the

RS232

terminal block

and the grounding screw to its left (see Figure 6-1 on page 6-4).

4.

Loosen the two screws that fasten the DB9 connector to the
mounting bracket, and remove the

serial interface converter

from

the bracket.

5.

Use a small screwdriver to pry open the

plastic case

of the serial

interface converter, as shown in Figure 6-2 on page 6-7.

The serial interface converter contains a main printed circuit board
and a daughter printed circuit board. The daughter board has a small
terminal block attached to it and the main board has a

DIP

switch

(

SW1

) mounted near the center of the board.

6.

Locate the switch assembly on the main board, and move the
switch in position 1 from ON to OFF. The standard ON state for
this switch is for point-to-point operation, while the OFF state is
needed for multi-point operation. See Table 6-3 on page 6-7 for
the proper settings of all four switches on the switch assembly.
