Setup and Operation

port P3. For a Hayes-compatible modem connection, this emulation provides dial-
in (call receiving) support (also referred to as Integrated Dial). This allows a remote
PC to initiate a call to the I/SITE LAN; however, the I/SITE LAN will not call out to
a remote PC. Once the I/SITE LAN is connected to a PC, either directly or through
a modem, two-way communication is provided.
✦
78061 – When connected to an auto-dial/auto-answer (AD/AA) Hayes-compatible
modem at port P4 or terminal block TB4, the I/SITE LAN performs the functions
of a CSI 78061 Tap (ViewCon setting 779806). This emulation provides dial-in and
dial-out support for two-way communication with remote PCs. Refer to
dial/Auto-answer (AD/AA)” on page 10
for a description of this emulated Tap and
the type of modems supported.
Unlike the 7801 Tap emulation, the 78061 Tap emulation allows the I/SITE to
initiate calls to remote PCs. Up to eight telephone numbers of at least 25 digits can
be stored in memory. (Refer to “Specifications” on page 43.)
✦
78035 – When connected to a direct-connect modem at port P4 or terminal block
TB4, the I/SITE LAN performs the functions of a CSI 78035 Tap (ViewCon setting
779803). This emulation provides two-way communication over dedicated data
lines.
✦
7810 – When an external serial printer is connected at port P3, the I/SITE LAN
performs the functions of a CSI 7810 Printer Tap. This is the only Tap emulation
that is set automatically by the I/SITE LAN, rather than being set manually through
the ViewCon. The 7810 Printer Tap emulation initiates when you select either
7801, 78061, or 78035 Tap emulation via the ViewCon and you connect a serial
printer to port P3.
Expansion Module
If used, the optional CLX (RS485 Serial Expansion) module provides a fourth commu-
nication interface using TB1 (RS485) port. This port provides a communication path to
an I/NET controller LAN. When connected through this port, the I/SITE LAN can
communicate with controllers connected on the same controller LAN (see
