APPENDIX C

OPTIONAL COAXIAL/TWINAXIAL INTERFACE

This appendix describes the configuration of the optional coaxial/twinaxial interface which replaces the standard parallel interface. The factory default settings in the Interface setup menu are Mode: Epson, I/O: CX/TX, and Data Bits: 8.

For your convenience, a parallel interface is also provided as part of the coaxial/twinaxial interface. The interface will automatically switch to receive data from either the coaxial/twinaxial port or the parallel port, after the timeout specified on the configuration DIP switches (SW1-7 & SW1-8). When data is received at the coaxial/twinaxial port, the interface will automatically switch to Printek emulation and select the EBCDIC font. The interface will automatically switch the printer to the default emulation selected in the Interface menu and select the parameters set for the current form in the Forms menu when data is received at the parallel port. For information about changing emulations and/or how to command other special printer functions via software control sequences, refer to the Programmer's Manual.

This interface is supplied with two connector cables. One cable provides a BNC type connector for coaxial connection. The other cable is a “smart T” for twinaxial connections, and automatically provides line termination if you have only one twinaxial cable connected. The interface also configures itself automatically for either coaxial or twinaxial operation, depending upon which of the above cables is attached to the 15 pin “D” connector. Some of the configuration DIP switches will also have different meanings depending upon which cable is attached. Refer to the following coaxial or twinaxial section as appropriate for these switch definitions and other configuration information.

COAXIAL OPERATION

This interface automatically configures itself for coaxial operation if the 15 pin “D” to BNC adapter cable is plugged in when power is applied to the printer.

The coaxial interface allows you to attach a FormsPro 4000 series printer to IBM mainframes via 3274, 3276, or 3174 Cluster Controllers, and emulates either the IBM 3287 or 3262 printer. This interface supports the three types of data transmitted from the Cluster Controller. These types are dependent upon the controller type, the system configuration, and the type of communication used. The types are:

DSC (Data Stream Compatible) 3270 type LU3

DSE (Data Stream Emulation) SNA type LU3

SCS (SNA Character Stream) SNA type LU1
