Output
This Signal indicates whether the ECR(ER-380) is busy. (H/W flow control)
①
MARK(Logic1) : The ECR is busy
②
SPACE(Logic0) : The ECR is not busy
③
The host transmits a data to the ECR, after confirming this signal.
④
When XON/XOFF flow control is selected, the host does not check this signal.

Input
This signal indicates whether the host computer or receipt printer can receive data.
(H/W flow control)
①
MARK(Logic1) : The host can receive a data.
②
SPACE(Logic0) : The host can not receive a data
③
The ECR transmits a data to the host or receipt printer, after confirming this signal.
④
When XON/XOFF flow control is selected, the printer does not check this signal.

VCC
Output
VCC(+5V/200mA) is supplied at 9Pin of D-SUB Connector.
Table2-12 RS-232C Signal Description
Caution:
The VCC is supplied for the barcode or device power source. The Supply Current 200mA is
total value including COM1 and COM2 Power Consumption. If the Total Power Consumption of the
attached devices is exceeded the specification(200mA), the system stops the VCC of D-SUB Connector
Caution:
If the device with 5V/200mA is connected to COM1, the VCC of COM2 can not use. If the device with
5V/200mA is connected to COM1, Other device with 5V/200mA can be connected to COM2 Port.
2-5-1-(e) H/W Flow Control Timing
When DTR/DSR flow control is select, before transmitting a data, the ECR checks whether the host is BUSY or not.
If the host is BUSY, ECR does not transmit a data to the host. If the host is not BUSY, ECR transmits a data to the
Host. The host is the same. Refer to the Interface Part of Chapter 7(Special Circuit Diagrams).
2-5-1-(f) S/W Flow Control Timing
When XON/XOFF flow control is selected, the ECR transmits XON(ASCII 11h) or XOFF(ACSII 13h) signal through
the Serial Data Line. If the ECR is busy, the printer transmits XOFF(ASCII 13h) to host through the Serial Data Line.
Then the host recognizes that the ECR is busy. So, the host does not transmit a data to the ECR. If the ECR is released
from busy, the ECR transmits XON(ASCII 11h) to host through the Serial Data Line. Then the host recognizes that the
ECR is not busy. And the host transmits a data to the ECR.
