A bit rate available by Serial I/F card :
19200bps, 9600bps, 4800bps, 2400bps, 1200bps, 600bps, 300bps
1.2.6 Interface selection
The printer has 3 interfaces; the parallel interface, USB interface and Type-B optional
interface. These interfaces are selected manually by Default Setting or selected
automatically.
Manual selection
One of the three interfaces can be selected by Default Setting.
Automatic selection
The automatic interface selection is enabled by Default Setting. In this automatic
interface selection mode, the printer is initialized to the idle state scanning which
interface receives data at power-on. Then the interface that receives data first is
selected. When the host stops data transfer and the printer is in the stand-by state
for the period of seconds specified by Default Setting, the printer is returned to the
idle state. As long as the host sends data or the printer interface is the busy state,
the selected interface is let as it is.
Interface state and interface selection
When the parallel interface is not selected, the interface gets info a busy state.
When the Type-B serial interface card is installed and it is not selected, the
interface sends XOFF and sets the DTR signal MARK. When the optional
interface is not selected, the printer sets “OFFLINE” bit of MNSTS register to the
optional interface. When the printer is initialized or returned to the idle state, the
parallel interface got into a ready state, the serial interface sends XON and sets the
DTR SPACE and the printer resets “OFFLINE” bit of MNSTS register to the
optional interface. Note that the interrupt signal such as a -INIT signal on the
parallel interface is not effective while that interface is not selected.
Preventing Hosts from Data Transfer Timeout
Generally, hosts abandons data transfer to peripherals when a peripheral is in the
busy state for dozens of seconds continuously. To prevent hosts from this kind of
timeout, the printer receives data very slowly, several bytes per minute, even if the
printer is in the busy state. This slowdown is started when the rest of the input
buffer becomes several thousands of bytes. At last, when the input buffer is full,
the printer is in the busy state continuously.
IEEE1284.4 on the parallel interface and on the USB interface do not require this
function.
