USB Device Port
The USB Device port supports a generic serial interface for an HMI or Tool device. The
USB Device port does not support firmware flash upgrades.
10B/100B Ethernet Port
The 10B/100B Ethernet port provides a path for commands and information
transmitted between field panels inside a firewall. This port provides both full- and half-
duplex 10Base-T or 100Base-TX compliant communications over a BACnet/IP
Automation Level Network (ALN). The highest possible communication speed is
automatically detected and selected.
RS-485 Port
The RS-485 port provides a path for commands and information transmitted between
field panels. This port provides communications over a BACnet MS/TP Automation
Level Network (ALN) or MS/TP Field Level Network (FLN). The communication speed
is set during startup.
The RS-485 port provides half-duplex, asynchronous serial RS-485 communications
over shielded twisted pair cable. The RS-485 connector is labeled + to indicate the
positive and negative connections; is a reference pin.
The TC-36 provides two RS-485 ports, which are labeled “A” and “B”.
All TC-36 models and the TC-16 and TC-24 "F" models support MS/TP FLN
devices on the RS-485 port.
BACnet MS/TP routed FLN is supported for Programmable TECs (PTECs), Unitary
Equipment Controllers (UECs), and third-party BACnet devices.
FIN Builder supports MS/TP routed FLNs and IP FLNs.
PPCL and Point Editing are currently not available on routed FLNs.
TC-36 RS-485 A and B Ports
The following table outlines the configuration options for the TC-36 RS-485 “A“ and “B“
ports.
ALN Protocol
RS-485 A Port (FLN 1)
RS-485 B Port (FLN 2)
BACnet/IP MS/TP FLN Not available
BACnet MS/TP MS/TP FLN Configured for MS/TP ALN
USB Host Port
The USB host port supports a USB printer and connection to a modem through a USB-
to-RS-232 adapter. A USB hub may be used to support both a printer and modem on
the USB host port.
On a BACnet/IP ALN, the USB Host port provides support for service modems and
line printers.
