NTP 297-8103-903Physical Connection of MAT
In connecting the ATM Switch and MAT, use a RS-232C cross cable fitted on one
end with a D-SUB 9 pin (male) connector for the AT M Switch and on the other end
with a connector meeting the shape of the MAT side connector.
There are two types of RS-232C cables used, straight cable and cross cable,
depending on the difference in the connection conditions of signal lines. Use the
RS-232C cross cable for connecting the ATM Switch and MAT.
The RS-232C connector of the MAT differs in sha pe depending on the model of th e
MAT. Use an RS-232C cross cable that has on one end a connector that can be
connected to the MAT and on the other end a D- SUB 9-pi n mal e con nector for the
ATM Sw it ch .
This section describes how to set PC9801 or IBM-PC as the MAT.
Figure 9-2 and Figure 9-3 show the RS-232C connector. Figure 9-4 and
Figure 9-5 show the connection method with a PC9801 and an IBM-PC,
The shape of the RS-232C connector on the 98 side is a D-SUB 25-pin (male)
The shape of the RS-232C connector on the IBM-PC side is a D-SUB 9-pin (male)
