Standard DCE to DTE RS-232C Cable
The standard DCE host to the printer (DTE) pin configuration follows..
Special Considerations for RS-232 Host Interface Users
If the READY light comes on and the ON-LINE light does not come on when you are
installing the printer, one or more of the pin signals on the RS-232 cable may be incorrect.
The host computer may be using a non-DCE RS-232C port. If so, you may have to modify
your cable or purchase a new cable with the proper pin assignments. Several possible
alternate RS-232C cable configurations follow.
