ESC/Kiosk Series 5300 Kiosk Thermal Printer
RS-232C INTERFACE
The RS-232C interface uses either RTS/CTS, DTR/DSR or XON/XOFF protocol. For RTS/CTS, changes in the RTS/CTS signal coordinates the information flow. For DTR/DSR, changes in the DTR/DSR signal coordinates the information flow. For XON/XOFF, data characters transmitted between the Host computer control communication data flow.
The RS-232C version of the Series 5300 offers the standard communications options which are configured in the flash.
RTS/CTS PROTOCOL
The RTS signal is used to control data transmission to the printer. It is driven high when the printer is ready to receive data and driven low when it cannot accept any more data. The host will transmit data to the printer when it recognizes the state of the printers RTS signal is high.
DTR/DSR PROTOCOL
The DTR signal is used to control data transmission to the printer. It is driven high when the printer is ready to receive data and driven low when it cannot accept any more data. The host will transmit data to the printer when it recognizes the state of the printers DTR signal is high.
XON/XOFF PROTOCOL
ASCII characters coordinate the information transfer between the printer and the host system. The printer sends an ASCII DC1(11Hex,XON) character when it is ready to receive data and it sends an ASCII DC3(13Hex,XOFF) character when it cannot accept any more data. The host system must monitor the communication link as in order to send data at the appropriate times.
Connectors
The following illustration shows the RS-232C communication connector and pin assignments. The connector is a 9-pin female D-shell connector and is located in the hollow cavity under the printer.

PARALLEL INTERFACE
PARALLEL INTERFACE SPECIFICATION (P1284)
Parallel Protocol
The Series 5300 uses a standard PC-compatible parallel interface. The following illustration shows the timing diagram for the interface protocol.
Compatibility Mode:
Busy
Acknowledge(L) pin 10

Strobe

Data(pins 9-2)
Th = Ts = .5uSec min.
1. The Host places its data on the data lines.
2. The host strobes the data into the printer latch using Strobe(L)
3. The printer Goes Busy(H) until the printer is ready to receive the next byte.
4. The printer acknowledges receipt of the data byte by Pulsing ACK(L).
5. The printer removes Busy(H) to allow continuation of data flow.
Note:
Definition and timing of the Parallel P1284 interface is beyond the scope of this manual. For a complete description of this interface refer to the IEEE P1284 Specification.
