7913 ATTACHMENT OF TWINAX AND COAX PRINTERS
 
 This  FLASH  is intended to clarify support for attachment of COAX and TWINAX
 IPDS printers using the IDATA 7913 LAN Attachment device.
 
 Although the 7913 supports both TWINAX and COAX IPDS printers, at the present
 time, TWINAX printers can not be used in S/370 or S/390 PSF host environments
 in all cases.  The IPDS microcode for TWINAX and  COAX  printer  models  does
 differ  on  some  of the printers.  Some of the TWINAX printer models are not
 currently supported by PSF/MVS, PSF/VM or PSF/VSE.  This includes  attachment
 to a S/370 host using the PSF/DIRECT features of PSF/2 and PSF/6000.
 
 Currently  PSF/MVS,  PSF/VM, and PSF/VSE support the TWINAX printer models of
 the 4028 and the 6400 printers. Only COAX models of all other  7913  attached
 printers  are  supported  by PSF/MVS, PSF/VM, and PSF/VSE. 
 
 The  AS/400  environment  however,  will support BOTH TWINAX and COAX printer
 models through a 7913 attachment.
 
 For example, the following configurations are NOT SUPPORTED:
 
 
    PSF/MVS----------------PSF DIRECT (PSF/2)----------7913--------3116
                (SNA)                         (TCP/IP)     (TWINAX)
 
 
    PSF/MVS----------------7913----------------3116
               (TCP/IP)           (TWINAX)
 
 
 
   The following are SUPPORTED environments:
 
    PSF/MVS-------------PSF DIRECT (PSF/2)----------7913------------4028
              (SNA)                        (TCP/IP)    (COAX or TWINAX)
 
 
    PSF/MVS----------------7913----------------4028
               (TCP/IP)        (COAX or TWINAX)
 
 
 
    PSF/400----------------7913----------------3116
               (TCP/IP)        (COAX or TWINAX)
 
 
 
    PSF/400------------PSF DIRECT (PSF/2)---------7913-------------3116
              (SNA)                       (TCP/IP)    (COAX or TWINAX)
 
 
 
 
 Note: This FLASH  should  be  considered  clarification  for  the  PSF/2  and
 PSF/6000 announcement letters 294-695 and 294-793 respectively.
