93RS-232 Serial InterfaceNOTE: The RS-232 serial interface circuit characteristics are compatible with the Electronic IndustryAssociation Specifications EIA-232-E and EIA-422-B.The RS-232 serial interface enables the printer to operate with bit serial devices that are compatible withan RS-232 controller. The input serial data transfer rate (in baud) is selectable from the printer's controlpanel. Baud rates of 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 baudrates are available.The length of the data cable from the host computer to the printer must not exceed 50 feet (15 meters) forRS-232.Table 6 Standard 500, 1000, 1500 and 2000 lpm ModelsRS-232 Serial Interface Connector Pin AsignmentsInput Signals Output Signals MiscellaneousSignal Pin Signal Pin Signal PinReceive Data (RD) 3 Transmit Status &Control Data (TD)2 Chassis Ground 1Clear To Send (CTS) 5 Request To Send (RTS) 4 Signal Ground 7Data Set Ready (DSR) 6 Data Terminal Ready (DTR) 20Data Carrier Detect (DCD) 8Table 7 RS-232 Serial Interface Connector Pin AssignmentsInput Signals Output Signals MiscellaneousSignal Pin Signal Pin Signal PinReceive Data (RD) 2 Transmit Status &Control Data (TD)3 Chassis/Signal Ground 5Clear To Send (CTS) 8 Request To Send (RTS) 7Data Set Ready (DSR) 6 Data Terminal Ready (DTR) 4Data Carrier Detect (DCD) 1Receive Data (RD). Serial data stream to the printer.Transmit Data (TD). Serial data stream from the printer for transmitting status and control information tothe host. Subject to protocol selection.Request To Send (RTS). Control signal from the printer. Subject to configuration.Clear To Send (CTS). Status signal to the printer indicating the host is ready to receive data/statussignals from the printer.Data Set Ready (DSR). Status signal to the printer indicating the host is in a ready condition.Data Carrier Detect (DCD). Status signal to the printer. The ON condition is required for the printer toreceive data.Data Terminal Ready (DTR). Control signal from the printer. Subject to configuration.
