Unit 5: Operating Modes
Page 5-4 MB400i/MB410i Operator Manual
NOTE
Some hosts monitor the Request-to-Send (RTS) signal (pin 4 of 25) to determine if the printer is
ready to receive data. Since the printer does not generate this signal, the RTS line must be held
true (high) in order to allow communication. Perform this by connecting the RTS pin to the Clear-
To-Send (CTS) signal (pin 5 of 25).
