Manager Card
3.2 Front Panel
The front panel of the Manager Card has the following controls and indicators:
∙Transmit and receive data LED’s for the command terminal data lines. These LED’s display data activity on both the transmit and receive data circuits.
∙AC power indication for each of the power supplies. These LED’s are fed from the AC power sensing circuits from each power supply.
∙A lock out switch for each of the 13 channels. These are provided to enable the user to set the poll number for individual KBU 64 cards. Once the cards have been programmed ALL the lockout switches must be set to enable the KBU 64s. The lockout switches can also be used to isolate a KBU card that is streaming unwanted alarms, so allowing other KBU cards to have access from the Manager Card.
∙An LED for each channel to indicate which channel is actively selected and in communication with the Manager Card. When another KBU 64 card is polled that card's LED will light and the previously selected card LED will extinguish.

The command port on Manager Rear Interface Card is a female 25 way 'D' type and uses the same V28 level circuits and pin connections as the standalone KBU 64.
