4 7798 I/SITE LAN
Communication
The I/SITE LAN provides up to four ports as follows:
✦
A standard asynchronous RS485 subLAN port (TB2).
✦
A synchronous/asynchronous serial port (P4) or terminal block (TB4). Serial port
P4 provides access to an external modem through a 10-conductor ribbon cable.
Terminal block TB4 provides a direct wiring connection to an external modem.
Both P4 and TB4 are the same serial port; therefore, only one of these two connec-
tors should be attached to a modem.
P4 is used to provide simple and quick connection of an external modem via the
standard Dial/Dedicated modem cable CSI Model Number CBL048 (P/N 606105–
0017; 6 ft). When it is necessary to locate the modem more than 6 feet (1.82 m)
away from the I/SITE LAN, TB4 may be used for discrete wire connection of a
modem cable extending up to 50 feet (15 m) to the external modem. Low capaci-
tance shielded cable of 24 AWG (0.206 mm
2
) or larger is recommended for this
interface.
