23 / 32 page  23 PRINT OPTIONS 00 800 9600 900 800 Set the baud rate to match the other serial communications equipment on the serial link. Normally, the baud rate is set to the highest value that all the serial equipment is capable of transmitting and receiving. 23 BAUD RATE ABBREVIATED PRINTING Select for full print or Command T transmissions (meter address, parameter data and mnemonics) or for abbreviated print transmissions (parameter data only). This will affect all the parameters selected in the print options. (If the meter address is 0, it will not be sent during a full transmission.) - Enters the sub-menu to select the meter parameters to appear during a print request. For each parameter in the sub-menu, select for that parameter information to be sent during a print request or for that parameter information not to be sent. A print request is sometimes referred to as a block print because more than one parameter information (meter address, parameter data and mnemonics) can be sent to a printer or computer as a block. PARAMETER DESCRIPTION FACTORY MNEMONIC Counter A CTA Counter B CTB Counter C CTC Rate RTE Max. & Min. MIN MAX A B C Scale Factors SFA SFB SFC A B C Count Load LDA LDB LDC 1 2 3 4 Setpoints * SP1 SP2 SP3 SP4 *Setpoints are option card dependent. DATA BIT Select either 7 or 8 bit data word lengths. Set the word length to match the other serial communications equipment on the serial link. PARITY BIT Set the parity bit to match that of the other serial communications equipment on the serial link. The meter ignores the parity when receiving data and sets the parity bit for outgoing data. If no parity is selected with 7 bit word length, an additional stop bit is used to force the frame size to 10 bits. METER ADDRESS Enter the serial meter (node) address. The address range is dependent on the parameter. With a single unit, configured for RLC protocol ( = ), an address is not needed and a value of zero can be used. With multiple units (RS485 applications), a unique 2 digit address number must be assigned to each meter.

These parameters are used to match the serial settings of the PAXI with those of the host computer or other serial device, such as a terminal or printer. This programming module can only be accessed if an RS232 or RS485 Serial Communications card is installed. This section also includes an explanation of the commands and formatting required for communicating with the PAXI. In order to establish serial communications, the user must have host software that can send and receive ASCII characters or Modbus protocol. Red Lion’s Crimson software can be used for configuring the PAXI (See Ordering Information). For serial hardware and wiring details, refer to the bulletin shipped with the option card. This section does NOT apply to the DeviceNet or Profibus-DP communication cards. For details on the operation of the Fieldbus cards, refer to the bulletin shipped with each card. u - Modbus RTU - Modbus ASCII - RLC Protocol (ASCII) Select the desired communications protocol. Modbus protocol provides access to all meter values and parameters. Since Modbus is included within the PAXI, the PAX Modbus option card, PAXCDC4, should not be used. The PAXCDC1 (RS485), or PAXCDC2 (RS232) card should be used instead. COMMUNICATIONS TYPE u TRANSMIT DELAY Following a transmit value (‘*’ terminator) or Modbus command, the PAXI will wait this minimum amount of time before issuing a serial response. to seconds Parameters below only appear when Communications Type parameter () is set to . |
