INTERFACES Menu
•
Report Status
. When a fault condition occurs in the printer, normally only
the active port reports the fault to the host. With this menu item enabled,
the port will report any fault even when it is not the current, active port.
The options are Disable (factory default) and Enable.
•
Data Term Ready
. Stands for Data Terminal Ready. This configuration is
part of hardware flow control and determines when the Data Terminal
Ready (DTR) signal is generated. This signal indicates if the printer is
ready to receive data.
•
True
(factory default). Continuously asserts the DTR signal.
•
False
. Never asserts the DTR signal.
•
On-Line and BNF (buffer not full)
. Asserts the DTR signal when the
printer is online and the internal serial buffer is not full.
•
Off-Line or BF (buffer full)
. Asserts the DTR signal when the printer
is offline or the internal serial buffer is full.
•
On-Line
. Asserts the DTR signal when the printer is online.
•
Request to Send
. This configuration is part of hardware flow control and
determines when the Request to Send (RTS) signal is generated. This
signal indicates whether or not the printer is ready to receive data.
•
On-Line and BNF
(factory default). Asserts the RTS signal when the
printer is online and the internal serial buffer is not full.
•
Off-Line or BF
. Asserts the RTS signal when the printer is offline or
the internal serial buffer is full.
•
On-Line
. Asserts the RTS signal when the printer is online.
•
False
. Never asserts the RTS signal.
•
True
. Continuously asserts the RTS signal.
•
Poll Character
. This option is for the Series1 protocol. Whenever the
printer receives this character, it sends a response to the host indicating
the current state of the printer (see Series1 protocol).
The range is 00-FF Hex, and the factory default is 00 Hex.
•
Poll Response
. This option is for the Series1 protocol. After receiving a
poll character, the printer will wait the poll response time in milliseconds
before sending the response.
The range is 0-30 ms, and the factory default is 0 ms.
•
Idle Response
.
This option is for the Series1 protocol.
•
Disable
(factory default).
•
Enable
. The printer sends a response character every two seconds
while the number of valid bytes in the buffer is less than 75 percent of
the buffer size.
