fitted with a modem chip.
If only remote on-site control and system status

To interface with ULTRAVAC™ controllers through a
Local Area Network (LAN), a TCP/IP Communication
module is installed at controller #1. Controller #1 is
wired to the LAN by an Ethernet cable.

Section 5.3. Any computer on the LAN that has
ULTRAVAC™ software installed can communicate
with the controllers. Appropriate precautions must be
taken to protect the Ethernet wiring from any possible
electrical interference (noise) caused by surrounding
machinery or equipment.

If multiple ULTRAVAC™ controllers are being used,
the additional controllers communicate to controller
