TEX-TOTAL

Flow Rate Totalizer

The TEX-TOTAL rate meter and totalizer

is ideal for  ow rate monitoring of trans-

mitters and sensors with mA output.

It features dual totalizers with low  ow

cut-o and roll over, and input signal av-

eraging to stabilise measurement.

The TEX-TOTAL features a 6-digit alpha-

numeric LED display, with scrolling text

prompts that guide you step-by-step

through the setup process. The unit is

easy to scale to suit your desired time

and measurement units.

Custom ASCII is a simple, custom protocol that allows connection to various PC con-

some devices.) Custom ASCII command strings must be constructed in this order:

Start - Use 'S' for the start character of a command string (not case sensitive). This

must be the  rst character in the string.

Controller Address - Use an ASCII number from '1' to '255' for the controller address.

If the character following the start character is not an ASCII number, then address '0' is assumed. All controllers respond to address '0'.

Read/Write Command - Use ASCII 'R' for read, 'U' for unformatted read, or 'W' for

write (not case sensitive). Any other character aborts the operation.

In Custom ASCII mode, data is normally read as formatted data (which includes decimals and any text characters that may be selected to show units). However it is also possible to read unformatted data by using a 'U' in the read command. There is no unformatted write command, as when writing to  xed point registers, any decimal point and text characters are ignored.

number from '1' to '65535'. This character must be speci ed for a write com-

mand, but may be omitted for a read command, (in which case the controller

will respond with the data value currently on the display).

Separator Character - The separator character can be either a space or a comma,

and is used to separate the register address from the data value.

Data Value - Must be an ASCII number. The absolute limits for this number are

–

1000000 to +1000000, but note that not all registers will accept this range.

Message Terminator - This is the last character, and must be either a '$' (dollar) or an

'*' (asterisk). Neither of these characters should be used elsewhere in the message string. If '$' is used, a 50ms minimum delay is inserted before a reply is sent. If '*' is used, a 2ms minimum delay is inserted before a reply is sent.

Controller Response - A er the controller has completed a read or write instruction,

it responds by sending a carriage return/line feed (CR/LF) back to the host. If

the instruction was a read command, the CR/LF follows the last character in the

ASCII string. If it was a write command, CR/LF is the only response sent back.

The host must wait for this before sending further commands to the controller.

If the controller encounters an error, it will respond with a null (0x00) CR/LF.

A.2 - Modbus (RTU) mode

Modbus (RTU) is an industry standard RTU slave mode that allows connection to a

wide range of devices. Modbus registers are all holding registers, and should be ac-

cessed via function codes 3 and 6.

A.3 - Ranger A mode

Ranger A is a continuous output, used to drive remote displays and other instru-

ments in the Rinstrum™ range. (Ranger is a trade name belonging to Rinstrum Pty

Ltd.) Ranger A output strings are constructed as shown:

Start - STX character (ASCII 02)

Sign - Output value sign (space for + and dash for -)

Output Value - Seven character ASCII string containing the current output value and

decimal point. (If there is no decimal point, then the  rst character is a space.

Leading zero blanking applies.)

Status - Single character output value status. 'U'=Under, 'O'=Over, 'E'=Error.

End - ETX character (ASCII 03)
