Event input using the evaluation board
Applicable receivers: | BD1090 | BD1092 | BD1092i
This topic describes how to condition and analyze event input signals when using the OEM GNSS I/O development boards. This knowledge also applies to the customers’ implementation of event inputs on their carrier board for the BD9xx.

Event 1 |
On the BD1090, BD1092 and BD1092i receiver modules, pin 8 is dedicated as an Event_In pin. This is a TTL only input; it is not buffered or protected for any inputs outside of 0 V to 3.3 V. It does have ESD protection. If the system requires an event to handle a voltage outside this range, the system integrator must condition the signal before connecting to the unit. |

Event 2 |
On the BD1090, BD1092 and BD1092i receiver modules, pin 7 is Event 2; however, it is multiplexed with COM3_RX and CAN_RX. The default setting is to have this line set to COM3_RX. Event 2 must be enabled to use Event2. This is a TTL only input; it is not buffered or protected for any inputs outside of 0 V to 3.3 V. It does have ESD protection. If the system requires an event to handle a voltage outside this range, the system integrator must condition the signal before connecting to the unit. |
