Rose electronic Automatic Switch manual Error

V.Port(s) do not time out

A.'Robust' X-on/X-off present.

Some printers, particularly the HP LaserJet, send X-on codes at timed intervals. Set the 'REVERSE CHANNEL DATA TIMEOUT' feature to Y. See 'CONFIGURATION' section for information on 'REVERSE CHANNEL DATA TIMEOUT'. Other options are disconnect pin 3 on port O, configure the printer for normal X-on/X-off, or configure port O to X-on/X-off.

B.Improper wiring

A computer which is powered off is making a port busy. Do not connect this computer's pin 6 to the unit. Alternately, enable ALLOW TIMEOUT ON BUSY. See 'CONFIGURATION' section for information on 'ALLOW TIMEOUT ON BUSY'.
