>>> RTU PROGRAMMER VERSION 3.03 HELP FILE <<<(continued)

Enabling RF spy mode on one RTU allows that RTU to report all incoming RF

messages over the serial link. These messages can be displayed using the RF Spy

screen available from the Utilities menu. While the RF Spy feature is enabled, the

unit will only operate in RF Spy mode and will not respond to the RF messages.

1.2 Send List:

The send list indicates up to four other RTUs to which this RTU can send its status.

All inputs will be sent to each of the units on the list. Enter an ID of 0 (zero) for any

unused entries. If any of these listed units fail to acknowledge the message, the

fail-safe state indicated by the letter next to that units ID will be set. The lettered

fail-safe states are listed in the lower right corner of the system configuration screen.

1.3 Repeat List:

When this unit receives a message from another unit, it can use the message AND

send it along to other RTUs. This information is configured in the repeat list. Each

incoming message can be repeated to up to four RTUs. The first column indicates

the unit that originates the message and the next four columns show the IDs of the

units which will receive the message.

1.4 Fail-Safe States:

If a unit fails to receive an acknowledge a fail-safe condition can be set. Each of the

four outputs can be set to a distinct fail-safe condition. The analogs can be set to any

value from 0% to 100%. A no change option is also available. For the analog outputs,

the no change is indicated by a 999%. Any number over 101% will be interpreted as a

no change. The programmer will automatically replace this number with 999% when it

downloads the information to the RTU. For the digital outputs, the choices are: open on fail,

close on fail, or no change on fail. The R column indicates whether the output should revert

to its initial condition when the signal is re-acquired. The choices for the field are yes or no.

Example 1: Revert to initial condition is selected for a digital output.

The initial condition for this output is relay open.

The fail-safe condition for this output is relay closed.

This output is not actively controlled by any other RTU.

The relay will be open when the system is started.

The relay will close when the RF link is lost.

The relay will open when the RF link is regained.

Example 2: Revert to initial condition is NOT selected for digital output.

The initial condition for this output is relay open.

The fail-safe condition for this output is relay closed.

This output is not actively controlled by any other RTU.

The relay will be open when the system is started.

The relay will close when the RF link is lost.

The relay will remain closed after the RF link is regained.
