ID = 1

5.The LEDs will light (and remain steady) to indicate the address. For example, if the ID DIP Switch is set to 1, LEDS D1 will on. If the ID DIP Switch is set to 3, LEDS D1 and D2 will be on.

7.After the address is set, the TankGate will begin normal operation with a blank database:

•CPU LED: Flashing once per second

•COM LED: Toggles when communicating to PC

•TXD: Off when there is no database. When tank gauges are being scanned, the TXD LED will flash

•RXD: Off when there is no database. When tank gauges are being scanned, the RXD LED will flash when a response is received.
