METTLER TOLEDO 6.1.1 NCI – ECR 6.1.1.1 OVERVIEW The serial communications protocol is used to interface Weigh-Tronix/NCI POS (Point-of-Sale) scales to ECR (Electronic Cash Registers), or other computing equipment (eg. personal computers). Baud rate and parity will be configurable. Start and stop bits will each be fixed at one (1). Data bits will be fixed at seven. Baud rates supported will be 1200, 2400, 4800, 9600 and 19200.
METTLER TOLEDO Name: Command: Response: Zero the scale Z Scale is zeroed, returns scale status. (see note 4) Shhhh Optional Commands Name: Command: Response: Request high-resolution weight H Returns decimal wt in 10x with units plus scale status. (see notes 2 and 3) xxx.xxxUUShhhh Returns lb-oz wt in10x with units plus scale status. xLBxx.xxOZShhhh Scale status only if wt < 0, initial zero error, in motion or out of capacity.
METTLER TOLEDO Weight Command: W This command causes the scale to return the displayed weight string in ECR format. The scale will usually return the displayed weight with leading zeroes (ie no leading zero suppression). However, if weight is negative, in motion, over capacity or under capacity, or if a zero error exists, the ECR protocol causes only the scale's status to be returned in response to a weight ('W') command. The returned weight string will include decimal point plus units of measure.
METTLER TOLEDO Scale Status Command: S There will be at least two status bytes. If bit 6 of the second status byte is set then there will be a third byte. Bit 6 of each successive byte will indicate whether or not another status byte follows. The bit will be clear (0) in the last status byte. At this time only the first three bytes are defined. Others may be added in the future. Bit 0 is the least significant bit in the byte while bit 7 is the most significant bit.
METTLER TOLEDO 6.1.2 (Reserved) 6.1.3 8217 Mettler Toledo 6.1.3.1 Host Communications The 8217 scale acts as a peripheral device when connected to a host computer. When the host requests weight data by sending an uppercase W, the scale will respond with the weight data or a status byte if the scale is in motion or an invalid state.
METTLER TOLEDO 6.1.3.2 Command Descriptions ASCII Commands (* MUST BE UPPERCASE CHARACTERS ONLY.) *ASCII Command From Host Scale Response Description Instructs scale to send weight data. (W=Weight Digit 0-9). The scale will respond as follows according to setup and status: C STX WW.WW R STX WW.WWW CR C STX WW.WWN R STX WW.WWWN CR C STX?status byte R Gross Weight Pounds. Gross Weight KG. Net Weight Pounds. ASCII N added after weight. Net Weight KG. ASCII N added after weight.
METTLER TOLEDO 6.1.3.3 Status Byte Format When the scale responds with STX?status byte CR , this indicates a status byte. The status byte contains scale status information, which can include net/gross mode, zero status, etc. The actual status byte sent will be an ASCII character which must be converted to binary to decode the bits. The scale status bit definitions are shown in the following table.
METTLER TOLEDO 6.1.3.4 Confidence Test Status Byte Format When the scale responds with STX? status byte CR, after requesting a confidence test (B), a confidence test status byte will be sent. The status byte contains scale status information, which can include net/gross mode, zero status, etc. The actual status byte sent will be an ASCII character which must be converted to binary to decode the bits. The confidence test status bits are shown in the following table.
METTLER TOLEDO 6.1.3.5 Tare Tare can be taken on an item two ways: Automatic or digital. REMOTE TARE The unknown weight of an object can be tared-off automatically by placing the object on the scale platter, then with the display in a stable non-motion and positive weight condition, sending an uppercase ASCII T character followed by CR from the host will automatically subtract the weight. The tare function must be enabled. Chain tare is not permitted.
METTLER TOLEDO 6.1.4 8213 Mettler Toledo 6.1.4.1 Host Communications The 8217 scale acts as a peripheral device when connected to a host computer. When the host requests weight data by sending an uppercase W, the scale will respond with the weight data or a status byte if the scale is in motion or an invalid state.
METTLER TOLEDO 6.1.4.2 Command Descriptions ASCII Commands (* MUST BE UPPERCASE CHARACTERS ONLY.) *ASCII Command From Host Scale Response Description Instructs scale to send weight data.
