Connects USB port of a PC to RS485 port of a Laureate meter with digital interface ordering option 2 (board P/N L485), or to a Laureate LT transmitter. Custom cable to connect the RS232 port of a PC to a Laureate meter with the RS232 option board (ordering option 1). Can be used with CBL02 to connect the USB port of a PC to a Laureate meter with an RS232 option board. Connects the RS232 port of a PC to the RS232 port of a Laureate LT transmitter. Allows a multi-point RS485 connection to Laureate meters with dual RJ11jacks and Laureate LT series transmitters with screw-clamp connectors. Allows dual RJ11 jacks of the RS485 option board of Laureate meters (digital interface ordering option 2) to be daisy chained and be addressed digitally with no need for a hub. Cable CBL02 plus CBL01 connects the USB port of a PC to a Laureate meter with an RS232 option board. CBL04 RS232 cable. Connects transmitter to PC com port. Connects CBL01 or CBL04 to PC USB port. Cable CBL02 plus CBL04 connects the USB port of a PC to the RS232 port of a Laureate LT transmitter.

The QScreen Controller has two serial communications ports: a primary serial port called Serial 1 that supports both RS232 and RS485 protocols, and a secondary serial port called Serial 2 that supports RS232. You can use one or both of the PDQ Board’s RS485 links to create such a multi-drop serial network. Systems of this type (4-wire, half-duplex) are often constructed to avoid "data collision" (bus contention) problems on a multi-drop network (more about solving this problem on a two-wire network in a moment).

Page 60 Block Communication Function for LED Display To display LED data for ASCII display that is synchronized to each digit, set data for each digit and validate this set data by display selection by communication (Communication Number FA65). The setting of a parameter was When using the TOSHIBA Inverter Protocol, use the W command to changed, but it returns to its write data into the EEPROM. Because all of the serial I/O routines on the PDQ Board are revectorable, it is very easy to change the serial port in use without modifying any high level code.

By taking advantage of the USB bus, the USB/RS485 Serial converter makes it easier than ever to add RS-422 / RS-485 serial ports and serial devices to your system. It is the ideal solution for connecting industrial devices such as laboratory testing and measuring equipment, monitoring devices, material handling equipment, and many more devices where mission critical applications are required. The SCK pin’s synchronous clock signal has configurable phase, polarity and baud rate so that it can interface to a variety of synchronous serial devices. The primary channel’s UART translates the bit-by-bit data on the serial cable into bytes of data that can be interpreted by the QED-Forth Kernel or by your application program. Straight through 6-wire data cable, not a 4-wire telephone cable or crossover cable. Splits single RJ11/12 jack into two RJ11/12 jacks, 6-wire. Recommended for programming of LNET1-485 communications board. CBL03-1 6-wire data cable, 1 ft, with RJ11 connectors. USB cable, A to Mini-B. Connects USB port of a PC to USB port of an LWIFI, LWIFIX or LNET1 communications board (ordering options A-D). If this limitation is not a problem, you can reverse the roles of the Serial1 and Serial2 ports, because they have identical communications capabilities.

You can implement the slave select lines by configuring Port A pins as outputs. Hardware is interfaced to the SPI via three PORTD pins named SCK, MOSI, and MISO brought out to pins 7, 8, and 10 on the Wildcard Port Header (see Appendix B). The QED-Forth kernel includes pre-coded drivers that configure and control the SPI for maximum speed data transfers. Bus cables are used in applications where signals must be quickly digitally transmitted, for example in flexible control and automation environments where there is a high rate of data flow and transmission. RS-485 signals are used in a wide range of computer and automation systems. For communication purposes, see the parameter list on inverter's instruction manual regarding the communication number, adjustment range and so forth.
