4.10 EMU Gateway (EMUGW)

The EMU Gateway point is used to manage scanning functions for the EMU point. Statistics are maintained for the communications between the Series 8130 and the tank gauging software (TankView or System IV). Special firmware is required on the TankGate to support the emulation functions.

4.10.1Parameters

The database parameters used by the EMUGW point are listed and described below:

Configuration Parame-	Function
ters

Protocol	Protocol to emulate. Valid values are:
	TSU Slave

ID	Address to respond to

Mode	Operational Mode

BaudRate	Baud Rate used to communicate with TankView

ComParams	Defines the number of data bits and the parity used by the com
	port. Examples include:
	IDAddress to respond to
	ModeOperational Mode
	BaudRateBaud Rate used to communicate with TankView
	ComParamsDefines the number of data bits and the parity used by
	the com port. Examples include:
	8O - 8 Data Bits Odd Parity
	8E - 8 Data Bits, Even Parity
	8N - 8 Data Bits, No Parity
	7O - 7 Data Bits, Odd Parity
	7E - 7 Data Bits, Even Parity
	7N - 7 Data Bits, No Parity
	The default is ‘8N’.

LevelConvert	Determines the units in which the level data will be displayed. F:
	feet, M: Millimeters. If no value is specified, no conversion will be
	performed.

TempConvert	Determines the units in which the temperature data will be
	displayed. F: Fahrenheit, C: Celsius. If no value is specified, no
	conversion will be performed.

DensityConvert	Determines the units in which the density data will be displayed. A:
	API, L: lbs/cu ft, K: kgs/m3. If no value is specified, no conversion
	will be performed.

Dynamic Parameters	Function

Message	Hex representation of the request sent by the host

Command	Current Command
