No-protocolcommunications allow data to be exchanged with standard RS-232C devicessuch as printers and bar code readers. Data can be printed out by a printer orread by a bar code reader. Handshaking is not supported for no-protocol communications.Communications ProcedureTransmissions1, 2, 3...1. Check to see that AR 0805 (the RS-232C Port Transmit Ready Flag) hasturned ON.245SectionSRM1(-V2) Communications Functions4-42.
Use the TXD(48) instruction to transmit the data.(@)TXD(48)S: Leading word no. of data to be transmittedSC: Control dataCN: Number of bytes to be transmitted (4 digits BCD), 0000 to 0256NFrom the time this instruction is executed until the data transmission is complete,AR 0805 ( or AR0813 for the peripheral port) will remain OFF. (It will turn ONagain upon completion of the data transmission.)Start and end codes are not included when the number of bytes to be transmittedis specified. The largest transmission that can be sent with or without start andend codes in 256 bytes, N will be between 254 and 256 depending on the designations for start and end codes.
If the number of bytes to be sent is set to 0000,only the start and end codes will be sent.256 bytes max.Start codeDataEnd codeTo reset the RS-232C port (i.e., to restore the initial status), turn on SR 25209. Toreset the peripheral port, turn on SR 25208. These bits will turn OFF automatically after the reset.Receptions1, 2, 3...1. Confirm that AR 0806 (RS-232C Reception Complete Flag) or AR 0814 (Peripheral Reception Complete Flag) is ON.2. Use the RXD(47) instruction to receive the data.(@)RXD(47)D: Leading word no. for storing reception dataDCNC: Control dataBits 00 to 030: Leftmost bytes first1: Rightmost bytes firstBits 12 to 150: RS-232C port1: Peripheral portN: Number of bytes stored (4 digits BCD), 0000 to 02563. The results of reading the data received will be stored in the AR area.
