Levelmaster Parameter Configuration Example

You want to use address 2 for the 5300/5400 transmitter and the host uses the following parameters:

Table 1-7. Parameters Used by the Host (in case of Levelmaster, example)

Parameter	Value
Baud Rate	9600
Start Bits	One
Data Bits	Seven
Parity	None
Stop Bits	One

To configure the 5300/5400 transmitter to communicate with the Host in this example, the following text string is written to the Modbus Message area.

HMC M2 A2 B9600 D7 PN S1.

NOTE

Include all the parameters when writing to the message area.

Note that an address must be unique on the bus.

HMC: These three letters are used for safety and will eliminate the risk of changing the configuration data by mistake.

M2: This means that the Levelmaster protocol is to be used.

A2: A indicates that the following is the new address (address 2). Leading zeroes are not needed.

B9600: B indicates that the following number is the new baud rate (1200, 2400, 4800, 9600, 19200).

D7: D indicates that the following data bits are to be used (7 = seven, 8 = eight).

PN: P identifies the following letter as parity type (O = odd, E = even, and N = none).

S1: S indicates that the following figure is the number of stop bits (1 = one, 2 = two).

Note: Start Bits are not configurable and cannot be set.
