3 8215 L&J Tankway Communications Interface Module
This communications interface module is the processing card that mounts on the TankGate
Interface (TGI) motherboard. The firmware installed on this card determines which protocol is
provided.
3.1 Features
• Supports up to 50 tanks
• Communicates using L&J Tankway protocol
• Interfaces to L&J Tankway compatible Tank Gauge transmitters
• ANSI/IEEE surge protection
The 8315 Tank Gate Interface uses L&J Tankway to communicate. There are a number of
transmitters that are compatible, including:
• L&J MCG 1000
• L&J MCG 1200
• L&J MCG 1500
• L&J MCG 2000
Note The 8315 Tank Gate Interface uses the 8215 communications module.
The 8215 communications module requires an external +48VDC power supply. It is also
possible to use the +48VDC power supply of the TankGate to power the tank gauge
transmitters, if there are fewer than 15 devices.
