CLEARjet GmbH CX-one
1.1.1 Operating RS 232 - Interface
A correct serial communication between Host and printer is only granted by using
serial interface cables including RTS / CTS Hardware-handshake and a handshake-
operating Host computer.
Note: While the printer is processing (printing / erasing) the handshake is active.
The printer won’t be able to respond to brief status requests.
Communication activity at the USB interface will also cause activation of the RS 232 -
Handshake.
1.2 Status Request (Polling)
The minimum delay for a brief status response aggregates to 10 ms. Any further brief
status request within this delay is ignored.
Recommended delay between status commands: min. 100 ms
Note: Shorter delays may cause loss of data or malfunction.
