Note 1: This should be connected to the port when using 100BASE-TX. It is possible to choose “connection” or
“disconnection” when using the 10BASE-T.
Note 2: Because the interface uses differential, twisted pairs of wires, make (A) and (a), (B) and (b), (C) and (c), and (D)
and (d) into pairs when using 100BASE-TX, and make (A) and (a), and (B) and (b) into pairs when using the 10BASE-T.
For the interfaces other than those, you can choose “disconnection” or “connection” ignoring the combination of pairs.
(3) RS-232C Straight Cable
When connecting a modem to the AUX port of GS4000, the RS-232C straight cable having a
D-SUB9 pin (female) and a D-SUB25 pin on each end should be used. Table 3.3-5 below
shows the pin arrangement of RS-232C straight cable.
