5.4 Macintosh Computer Compatibility Requirements
When using the ISDN TA/V in conjunction with a Macintosh computer,
all that is required to establish a successful installation is the appropriate
connecting cable, and then, depending on the type of handshaking being
used, a small change may have to be made to the ISDN TA/V’s operating
configuration.
Although a Macintosh cable is not supplied with the unit, these are readily
available from your computer dealer. Alternatively you may choose to build
one yourself by following the appropriate pin-out diagrams shown in Figures
5.2 and 5.3

Before you can select the appropriate cable for connecting the DTE interface
to your Macintosh computer, it is important that you first ascertain whether
the communication software that you are going to use to command the ISDN
TA/V supports hardware or software handshaking as the means of flow
control. Having done this, you must use a compatible cable to connect to
the ISDN TA/V.

Using this cable requires no change to the ISDN TA/V’s factory-default
configuration.
