These settings correspond to binary 00101011 = 2B Hex. Send the command *15P1B2B. The meter will
respond with 151B.
11.25 Communication Bus Format (“BUS FT”)
This item is 1 byte (2 characters). It specifies bus information such as protocols. It uses prefixes G, P, R, and
W with the suffix 1C.
Table 11.23 shows bit assignments.

EXAMPLE: You are in Batch Mode. You want to configure RAM such that the mode is Point-to-Point
Continuous with a message handshake; you do not want to use a check sum, line feed, and have no RS-232 or
RS-485 board installed. You want to print each item on a new line (meaning you want to use the as the
item spacer). The bits values for these choices correspond to binary 1000100= 80 Hex. Send the command
*15P1C80. The meter will respond with 151C.
11.26 RS-485 Meter Address (“ADDRES”)
This item is 1 byte (2 characters). It specifies the address of a meter where more than one meter is on the
transmission bus. It uses prefixes G, P, R, and W with the suffix 1D. Data values can be 1 to 199 decimal = 1
to C7 Hex.
EXAMPLE: You want to change the address of meter 15 to 24 in RAM. Send the command *15P1D24.
The meter will respond with 15P1D. The meter address is now 24 and commands must begin with *24…
11.27 Time Between Each Transmission (“SER TI”)
This item is a 2-byte Hex value. It specifies the time between transmissions for Continuous Mode only. It uses
prefixes R, P, R, and W with the prefix 1E.
Table 11.24 shows data values.
