Mounting the TRC-8543
Caution The TRC-8543 is a thermally active device that dissipates heat.
Refer to the user manual of the host this device directly connects to for
specific information regarding thermal management. Not following
mounting requirements may aect the system ambient temperature
and/or the measurement accuracy of modules in the system.
Caution To meet thermal management requirements, do not zip tie more
than six cables in a bundle, and allow for air flow around the bundle. If
used with a cRIO or cDAQ chassis, mount all cables at least 152 mm
(6.0 in.) from the chassis and do not mount more than six cables directly
beneath the chassis.
You can route and strain relieve the TRC-8543 similarly to ordinary cables. You also
can panel mount it using its removable jackscrews, zip tie, or screw mount it. The
screw mounting holes support #6 and M3 screws spaced 35.56 mm (1.400 in.)
center-to-center, with minimum length of 23 mm (7/8 in.). The TRC-8543 supports
zip ties up to 5.33 mm (0.210 in.) wide.
The following figure shows jackscrews, zip tie mounting slots, and screw mounting
holes on the TRC-8543.

Wiring to the TRC-8543
The TRC-8543 is used with an NI-XNET interface host port.
Figure 4. TRC-8543 Connections
The TRC-8543 has one 9-pin male D-Sub connector that provides connections to a
CAN bus. The TRC-8543 has pins for CAN_H and CAN_L, to which you connect the
CAN bus signals. Connect these signals using twisted-pair cable.
The port has two common pins (COM) that are internally connected to the TRC-8543
isolated reference and serve as the reference ground for CAN_H and CAN_L. You can

TRC-8543

connect the CAN bus reference ground (sometimes referred to as CAN_V-) to one or
both COM pins.
The D-Sub connector shell connects through the TRC-8543 shielding to the
connector on the host port end. The shielding does not electrically connect to the
COM signals.
Caution When tightening the D-Sub connector jackscrews, do not exceed
the maximum jackscrew torque of 0.56 N · m (5.0 lb · in.).
The TRC-8543 receives power from the NI-XNET host port, but also requires an
external power supply of +9 V to +30 V to operate in Low-Speed/Fault-Tolerant
mode. Supply power from the CAN bus to the VSUP pin.
Note Power on VSUP is required for Low-Speed/Fault-Tolerant CAN
operation, but is not required for High-Speed CAN operation.
The TRC-8543 features soware-selectable bus termination for both CAN High-
Speed/Flexible Data-Rate and Low-Speed/Fault-Tolerant transceivers. For High-
Speed/Flexible Data-Rate mode, you can enable 115 Ω of termination resistance
between CAN_H and CAN_L through an API call. For Low-Speed/Fault-Tolerant
mode, you can select either 1.11 kΩ or 4.99 kΩ of termination resistance for RTH and
RTL through an API call (refer to the Termination Resistors section for more
information). If you choose to use external termination, Table 4 lists recommended
termination resistor values.
The following table lists the TRC-8543 pinout.

CAN Bus Topology and Termination
A CAN bus consists of two or more CAN nodes cabled together. The CAN_H and
CAN_L pins of each node are connected to the main CAN bus cable through a short
connection known as a “stub.” The pair of signal wires, CAN_H and CAN_L,
constitutes a transmission line. If the transmission line is not terminated, each
signal change on the bus causes reflections that may cause communication errors.
High-Speed/Flexible Data-Rate CAN
Because the CAN bus is bidirectional, both ends of the cable must be terminated.
However, this requirement does not mean that every node on the bus should have a
termination resistor; only the two nodes at the far end of the cable should have
termination resistors.
The following figure shows a simplified diagram of a CAN bus with multiple CAN
nodes and proper termination resistor (Rt) locations.
Figure 5. CAN HS/FD Bus Topology and Termination Resistor Locations
Low-Speed/Fault-Tolerant CAN
Every device on a low-speed/fault-tolerant CAN network requires a termination
resistor for each CAN data line: RRTH for CAN_H and RRTL for CAN_L.
The following figure shows a simplified diagram of a low-speed/fault-tolerant CAN
bus with termination resistor placements.

The termination resistors (Rt) should match the nominal impedance of the CAN
cable and therefore comply with the values in the following table. The onboard,
soware-selectable termination has a nominal value of 115 Ω. If you are not using
the onboard termination, use the values listed in the following table.

Low-Speed/Fault-Tolerant CAN
Unlike High-Speed/Flexible Data-Rate CAN, Low-Speed/Fault-Tolerant CAN requires
termination at the Low-Speed/Fault-Tolerant CAN transceiver instead of on the
cable itself. Termination requires two resistors, RTH for CAN_H and RTL for CAN_L.

TRC-8543

This configuration allows the NXP fault-tolerant CAN transceiver to detect and
recover from bus faults. It is important to determine the overall termination of the
existing network, or the termination of the individual device, before connecting it to
a low-speed/fault-tolerant port. NXP recommends an overall RTH and RTL
termination of 100 Ω to 500 Ω (each) for a properly terminated low-speed network.
You can determine the overall network termination as follows:
1
RRTHoverall
=1
RRTHnode1
+1
RRTHnode2
+1
RRTHnode3
+1
RRTHnoden
NXP also recommends an individual device RTH and RTL termination of 500 Ω to
16 kΩ. Aer determining the existing network or device termination, you can use the
following formula to indicate which nearest value the termination property needs to
be set to produce the proper overall RTH and RTL termination of 100 Ω to 500 Ω
upon connection of the card:
where RRTH overall should be 100 Ω to 500 Ω
NI-XNET Low-Speed/Fault-Tolerant CAN hardware features soware selectable bus
termination resistors, allowing you to adjust the overall network termination
through an API call. In general, if the existing network has an overall network
termination of 125 Ω or less, you should select the 5 kΩ option for your NI-XNET
device. For existing overall network termination above 125 Ω, you should select the
1 kΩ termination option for your NI-XNET device.
Onboard termination on the low-speed/fault-tolerant ports of the TRC-8543 is set
through the NI-XNET soware to either 1.11 kΩ or 4.99 kΩ.
Cable Lengths
The cabling characteristics and desired bit transmission rates aect the allowable
cable length. You can find detailed cable length recommendations in the ISO 11898,
CiA DS 102, and DeviceNet specifications.
ISO 11898 specifies 40 m total cable length with a maximum stub length of 0.3 m for
a bit rate of 1 Mb/s. The ISO 11898 specification says that significantly longer cable
ni.com

TRC-8543

lengths may be allowed at lower bit rates, but you should analyze each node for
signal integrity problems.
High-Speed/Flexible Data-Rate CAN
The maximum number of nodes depends on the electrical characteristics of the
nodes on the network. If all nodes meet the ISO 11898 requirements, you can
connect at least 30 nodes to the bus. You can connect higher numbers of nodes if
the nodes’ electrical characteristics do not degrade signal quality below ISO 11898
signal level specifications.
The TRC-8543 electrical characteristics allow at least 110 CAN ports on a network.
Low-Speed/Fault-Tolerant CAN
The maximum number of nodes depends on the electrical characteristics of the
nodes on the network. If all of the nodes meet the requirements of Low-Speed/
Fault-Tolerant CAN, up to 32 nodes may be connected to the bus.
TRC-8543 Hardware Overview
The TRC-8543 has one full-featured CAN port that is isolated from the host it is
plugged into. Soware can select between either an NXP TJA1043T High-Speed CAN
transceiver or NXP TJA1055T Low-Speed/Fault-Tolerant CAN transceiver by
controlling on-board relays. The TJA1043T is fully compatible with the ISO 11898
standard and supports baud rates up to 2 Mbps. The NI-XNET driver enables baud
rates up to 8 Mbps. The TJA1055T is fully compatible with the ISO 11898 standard
and supports baud rates up to 125 Kbps.
