•If the programmer is connected to an INCOM Network, the message shown in Figure 3 - 2 will first be displayed followed by the INCOM message shown in Figure 3 - 4. The top level menu will then be displayed (Figure 2 - 9) .

•If the programmer is successful in its device search, the same in progress type message is displayed as shown in Figure 3-2. Refer to Figure 3-5for a typical baud rate and address message momentarily dis- played once the trip unit is identified. The top level main menu is ultimately displayed and the program- mer is ready for use (Figure 2-9).

3-4 FUNCTION OVERVIEW3-4.1 SELECT ADDRESS (SA)

The Select Address menu item is used when it is desired to communicate over the 3-pin INCOM connection to an OPTIM trip unit. The address of the breaker you desire to communicate to is entered here. Note that an auxiliary power module must be plugged into the OPTIMizer for the OPTIMizer’s INCOM transceiver to work. Selectable addresses are in the range 001-FFE hexadecimal (001 to 4094 decimal).

3-4.2 FIND BAUD/ADDRESS (FI)

This menu item is used to retrieve the address and baud rate of the OPTIM trip unit connected to the OPTIMizer’s custom phone cord. The OPTIMizer executes this function automatically when the OPTIMizer is first turned on. Several attempts will be made to retrieve the address and baud rate. If no trip unit is connected to the OPTIMizer at the time the OPTIMizer is turned on,

an error message will be displayed.

3-4.3 FIND PRODUCT ID (ID)

The breaker frame type is displayed when this menu item is selected.

3-4.4 CHANGE BAUD/ADDR (BA)

The baud rate of the trip unit can be changed to that of the system by using this menu item. The baud rate is programmable to either 1200 or 9600 baud. All breakers connected together on a line must communicate at the same baud rate.

The address of a given breaker can be changed by using this menu item. Valid addresses of 001-FFE Hexadecimal (001 to 4094 decimal) can be used, how- ever, when OPTIM trip units are connected to a Breaker Interface Module (BIM) the range of usable addresses is from 1-32 hexadecimal (1-50 Decimal).

3-4.5 RATING PLUG (RP)

The rating plug installed in a trip unit can be read using this command.
