Remote Communications

The following discussion deals primarily with communications between

the

FLO and Host (typically WinCCU).

To communicate with the Host, the

FLO has a remote communications

port that can function as RS232, RS485 or RS422. Depending on the

customer's order, most units are shipped with an appropriate cable

between the 15-pin connector (J3) and the communication's device such

as a radio. The other option is a termination board that plugs directly on

the 15-pin connector with appropriate terminals labeled. (See pages 10 &

11)

After installation of the

FLO and with the communications path

complete, the user needs to enter the appropriate communications

parameters. The

FLO was most likely shipped with Com1 set up for

Totalflow Remote Protocol. If not, select the protocol using the Entry

mode of PCCU32 as shown below. The protocol must be selected first

for the appropriate communications parameters to be displayed. A

blinking telephone pole symbol " " in annunciator position A8 (default)

indicates Com1 port is active. See Visual Alarm Codes on page 17 for a

full description of alarm characters, locations, and descriptions.

Other Communication Options

After selecting the protocol, verify the other communication parameters.

All communication parameters with the exception of modems are found

on the Setup and Advanced tabs. Modem parameters have there own

tab. Systems are shipped with default settings for communications but

may need fine tuning. The Schedule tab parameters are only required if

the

user

wants

power-up

the

communication's

port

and

communication's devices at designated times to conserve power.
