LonWorks Twisted Pair Control Module User's Guide iii
Welcome
Echelon’s LONWORKS®Twisted Pair Control Modules contain the core elements
for device designs using LONWORKS technology. The core elements of a control
module are an FT 5000 Smart Transceiver or Neuron®3150®Chip, crystal clock
circuit, I2C EEPROM or JEDEC MO-052 AE PLCC memory socket (32-pin
rectangular), Communications Transformer or twisted pair transceiver, and
unbuffered access to the I/O, SERVICE~, and RESET~ signals.
All of the Neuron 3150 LONWORKS Twisted Pair Control Modules share a
common footprint and I/O interface to allow systems with different media
requirements to share common application electronics board designs. The FT
5000 Control Module has a similar I/O interface so that you can easily modify
designs that use a Neuron 3150 Control Module to use the FT 5000 Control
Module.

Reset Pin
Pin 2 of the JP1 header on the FT 5000 Control Module is the Smart Transceiver
reset pin (RST~). Pin 9 of the P1 header on the Neuron 3150 Control Module is
the Neuron Chip reset pin (RESET~).
The reset pin on the Smart Transceiver or Neuron Chip can be driven low
externally or can be used as an open drain output to provide a reset signal for the
application circuit. The details of the recommended circuit and loading on the

6 Electrical Interface
reset pin are described in the Series 5000 Chip Data Book or the Neuron Chip
Data Book.
Service Pin
You can access the service pin (SVC~) of the FT 5000 Control Module at pin 10 of
the JP1 header. You can access the service pin (SERVICE~) of the Neuron 3150
Control Module at pin 18 of the P1 header.
This pin is used for various network installation and maintenance scenarios. The
function of this pin is described in the Series 5000 Chip Data Book or Neuron
Chip Data Book.
Figure 2shows a typical circuit for the device service pin. Typical applications
do not require debounce conditioning of momentary push buttons attached to the
service or reset pins. The software response time associated with these inputs is
long enough to effectively provide a software debounce for switches with a contact
bounce settling time as long as 20 msec.

Mechanical Footprint
Figure 4shows the mechanical footprint for an FT 5000 Control Module. You
can solder the module directly to your PCB as a through-hole part or mount it in
a connector. The module includes a male Samtec, Inc. TSW-113-08-T-D-RA
square post header, which fits into a 13x2 pin female connector, such as a
Samtec, Inc. SSM-113-L-DV surface mount socket strip.

The figure also shows positioning for Richco®Inc. VMCGE-30M-01 vertical

depending on your application.
Neuron 3150 Control Module
The following sections describe the mechanical interface for the Neuron 3150
Control Modules.

LonWorks Twisted Pair Control Module User's Guide 9
Mechanical Footprint
The Neuron 3150 Twisted Pair Control Modules share a common footprint and
connectors as shown in Figure 5on page 10. The most common control module
mounting scenario uses socket strips on the application electronics board which
connect with P1 and P2 as shown in Figure 6and Figure 7on page 11.
Example vendor information for socket strips that mate with the 0.025 inch (0.64
mm) square header posts of P1 and P2 are listed in Table 6on page 11.
If necessary, taller socket strips can be used to gain more clearance between the
control module and the application board. Decisions about component placement
on the application electronics board must also consider the electromagnetic
interference (EMI) and electrostatic discharge (ESD) issues discussed in Chapter
5, Design Issues, on page 27.
Figure 6and Figure 7show the maximum height of parts on both sides of the
control modules. Application designs using the transformer-isolated twisted pair
transceivers should maintain a minimum of 0.15 inch (3.81 mm) clearance from
P2 pins and traces on the network side of the transformer to achieve the
minimum isolation specified for these modules. Refer to EMI Design Issues on
page 28 and Neuron 3150 Control Module Keepout Areas on page 31 for isolation
requirements.
Three plated mounting holes that accept No. 6 (3.5 mm) mounting screws are
electrically connected to the control module ground plane. When the 0.025 inch
(0.64 mm) square posts of P1 and P2 are inserted into the sockets they provide
enough holding strength (3 oz (85 g)/pin) to secure the control module against
shock and vibration to the operating limits of the components on the control
module. However, at least one metal standoff and fastening screw located at the
mounting hole near the P2 connector is recommended to meet EMI limits and for
ESD protection (see Chapter 5).
For the TP/FT-10 control modules, the recommended metal standoff height is
0.56 inch (14.3 mm) to provide adequate clearance. Note that the Methode
Socket (referenced in Table 6) in this case is not recommended, because its
minimum insertion depth requirement is not met. Use of metal 0.50 inch (12.7
mm) #6 standoffs together with metal spacers can achieve this. Alternately,
metal 0.56 inch (14.3 mm) #6 standoffs alone will be adequate. For the TP/XF
and TP/FT-10F control modules, 0.50 inch (12.7 mm) #6 metal standoffs alone are
recommended.
Figure 8on page 12 presents the height restrictions of the component side of the
control module. The board is divided into two height zones: the maximum height
of components in the first zone is 0.20 inch (5.1 mm). The second zone's
components are 0.47 inch (11.93 mm) for the TP/XF and TP/FT-10F control
modules and 0.555 inch (14.1 mm) for the TP/FT-10 control module. Care should
be taken to ensure that no components on the application electronics board
interfere with the height restricted areas of the control modules.
Figure 9on page 13 shows the recommended PCB pad layout for the application
electronics board to interconnect a control module with an application board that
has socket strips mounted on the component side.
