SLTA-10 Adapter Overview
The SLTA-10 Serial LonTalk Adapter (Models 73351, 73352, and 73353)
is a network interface that enables any host processor with an EIA-232
serial interface to connect to a LONW
Adapter extends the reach of LONW
hosts, including desktop, laptop, and palmtop PCs, workstations,
embedded microprocessors, and microcontrollers.
The SLTA-10 Adapter has two modes of operation: NSI and MIP modes.
The SLTA-10 NSI mode is compatible with LNS-based applications.
The SLTA-10 MIP mode is compatible with legacy applications based on
the LonManager® API or the HA host application software. The SLTA-
10 MIP mode is a replacement for the SLTA/2 Serial LonTalk Adapter.
An externally accessible DIP switch determines the mode of operation.

Introduction
The SLTA-10 Adapter is the latest addition to the SLTA product family. It is an EIA-232
(formerly RS-232) compatible serial device that allows any host with an EIA-232 interface and
proper software to communicate with a L
ONWORKS
network.
An SLTA-10 Adapter enables the attached host to act as an application node on a L
network. When used with a PC host and the LNS Developer’s Kit for Windows software, the
SLTA-10 Adapter can be used to build sophisticated network management, monitoring, and
control tools for L
applications such as the LonManager LonMaker installation tool, LonManager DDE Server, or
applications based on the LonManager API.
An SLTA-10 Adapter can be connected to the host through a pair of modems and the telephone
network, allowing the monitoring, control, or network management computers to be remote from
the network. The SLTA-10 Adapter can be set up to answer incoming calls from a remote host. In
addition, any node on the local network can initiate a telephone call to a remote host computer. A
new feature, available only in the SLTA-10 NSI mode (see below), allows the SLTA-10 Adapter
itself to initiate a phone call to a remote host computer.

Two Modes of Operation: SLTA-10 NSI and MIP Modes
The SLTA-10 Adapter provides both the network services interface (NSI mode) functionality for
use with LNS-compliant applications, and network interface functionality (MIP mode) for use with
LonManager API-based applications.
There are two separate firmware images in the SLTA-10 Adapter. The two separate images have
different link layer protocols, different network drivers, different buffer capacity, and different
functionality. The two modes of operation are the SLTA-10 NSI mode and the SLTA-10 MIP
mode. The mode of operation is controlled by an externally accessible DIP switch at power-up.
Table 1 illustrates the differences between the SLTA-10 NSI mode, the SLTA-10 MIP mode, and
the SLTA/2.

SLTA-10 NSI Mode Features
The most important new feature of the SLTA-10 NSI mode is the NSI functionality for use with
LNS-compliant applications. Other important features available only in the SLTA-10 NSI mode
include: SLTA-10 initiated dial-out, a Windows NT driver, a high performance link layer protocol,
and the SLTALink Manager software. These features are not available in SLTA-10 MIP mode.
The improved hardware form factor applies to both modes of operation and is listed in Table 1.
In SLTA-10 NSI mode, an SLTA-10 Adapter supports applications based on both the LNS software
and the LonManager API.
SLTA-10 MIP Mode Versus the SLTA/2
In SLTA-10 MIP mode, the SLTA-10 Adapter is a replacement for the SLTA/2 Serial LonTalk
Adapter, with an improved form factor. The network connector on the SLTA-10 Adapter is the
color-coded removable screw terminal (Weidmuller), instead of the RJ45 used on the SLTA/2
Adapter. The SLTA-10 Adapter input power options include 9-30VAC or DC, or a 9V wall mount
supply. The SLTA-10 Adapter operates at 10MHz for all transceiver types; the SLTA/2 operates at
5MHz or 10MHz, depending on transceiver type. In addition, the SLTA-10 configuration DIP
switches are externally accessible. The SLTA-10 enclosure has been improved to allow wall
mounting, without requiring a bracket.
The SLTA/2 and the SLTA-10 MIP mode use the same drivers and li nk layer protocol.
The SLTA-10 Adapter Configurations
The SLTA-10 Adapter is available with the following transceiver and power supply options:
Transceivers
•
TP/FT-10, TP/XF-78, and TP/XF-1250. The FTT-10A (78kbps, free or bus topology), TPT/XF-78
(78kbps, bus topology) and TPT/XF-1250 (1.25Mbps, bus topology) transceivers all use
transformer-isolated, differential transmission.
Power supply
•
(Model 78030), continental European (Model 78020), and Japanese (Model 78030)
configurations. Plug-in power supplies are sold separately. Alternately, screw terminals are
supplied for use with a 9 to 30VAC/DC power sources.

Software for the SLTA-10 MIP mode is distributed in the Connectivity Starter Kit (Model 58030-
01) and from the Developer’s Toolbox of the Echelon web site.
SLTA-10 Adapter User’s Guide 14
LNS 1.0, 1.01, and 1.5 Compatibility
When the SLTA-10 Adapter is connected directly to the PC host (i.e., no modems), the SLTA-10
Adapter uses a direct connection. For a direct connection, the SLTA-10 Adapter behaves like any
other NSI, such as the PCLTA-10 Adapter or the PCC-10 PC Card. In this case, an SLTA-10
Adapter may be used without issue with applications based on LNS 1.0, 1.01, or 1.50.
The SLTA-10 Adapter is also designed so that a PC host can be connected to the network through
a pair of modems and the telephone network. In this scenario, the PC is a remote host. When the
PC initiates the phone call to the SLTA-10 Adapter, the remote host is said to “dial-in to the
network”. When the SLTA-10 Adapter initiates a call to the PC, the SLTA-10 is said to “dial-out to
the remote host”. Once the phone connection is established, the application running on the remote
host can perform network management, monitoring, or control activities.
Applications based on LNS 1.0 or 1.01 do not have full functionality with respect to the SLTA-10
Adapter and modems because LNS 1.0 and 1.01 have default system behavior that is incompatible
with using the SLTA-10 Adapter through modems. For instance, an application based on LNS 1.0
and 1.01 terminates (i.e., shuts down) in a manner that interferes with one the automatic dial-out
initiation techniques. In LNS 1.0 or 1.01 when an LNS host application is terminated, all host
network variables and connections to these variables are removed from the LNS database. One
way the SLTA-10 Adapter can initiate a phone call, or automatically dial-out, is based on a
network variable update being sent to the SLTA-10 Adapter. Since the termination of the
application on the PC host results in the removal of all network variable connections to the host,
no network variable update can be sent to the SLTA-10 Adapter. Thus, one of the two
mechanisms that support automatic dial-out is unavailable.
LNS 1.0 and 1.01 have no special knowledge of whether the SLTA-10 Adapter is remotely
connected through a pair of modems. However, LNS 1.5 automatically detects that the SLTA-10
Adapter is remote at commissioning. Using a remote SLTA-10 Adapter affects the default system
behavior by allowing the system to function as desired. Upon termination of an application based
LNS 1.5, the LNS host API will determine if the NSI uses modems and if there are any explicitly
bound network variables on the host. If both of these conditions are met, LNS does not remove the
connections or host network variables. In addition, LNS leaves the SLTA-10 Adapter configured.
Thus, LNS 1.5 fully supports the SLTA-10 Adapter accessed through a modem configuration.
In summary, LNS 1.5 fully supports using the SLTA-10 Adapter with modems. LNS 1.0 and 1.01
do not support the use of the SLTA-10 with modems, although direct connect interfaces are
supported.
Note: A remote (via modems) LNS Server requires a dedicated SLTA-10 Adapter.
Thus, some networks may require multiple SLTA-10 Adapters —one for the
remote LNS Server and others to allow access for other PCs.
SLTA-10 Adapter User’s Guide 15
TAPI Compatibility
The SLTALink Manager software uses TAPI release 1.3 or higher. This is supported in Windows
NT 4.0, but not in Windows NT 3.51. Thus, Windows NT 3.51 does not support the use of the
SLTA-10 Adapter with modems, however, Windows NT 3.51 does support a direct connect
interface.

Once the SLTA-10 Adapter is physically attached to the desired channel, power must be supplied
via one of the power input connectors. The SLTA-10 Adapter may be ordered with a plug-in power
supply, or may be used with any 9 - 30VAC/DC supply. Four plug-in power supply options are
available for the SLTA-10 Adapter, depending on the country in which the SLTA-10 Adapter is
used: USA/Canada, United Kingdom, Continental Europe, or Japan. The output voltage of these
supplies is a nominal +9VDC at 500mA. Power consumption is typically <1 Watt, independent of
input voltage.
Table 3 describes the basic characteristics of the four power supply types.

Terminal Equipment (DTE). A DCE device connects to a DTE device, unless a null modem cable is
used. Using a null modem cable, a DCE device connects to a DCE device and a DTE device
connects to a DTE device. The SLTA-10 Adapter is a DCE device.
The standard configuration for a PC/AT EIA-282 serial I/O port is a DTE device. PCs usually take
the ‘terminal’ role in communications. Modems should always be DCE devices. To connect an
SLTA-10 Adapter to a PC, simply connect one end of the serial cable to the SLTA-10 Adapter, and
the other end of the cable to the PC’s serial port. To connect an SLTA-10 Adapter to a modem, a
special null modem cable must be used. Note that a standard off-the-shelf null modem cable will
not work in this configuration.
Echelon offers the Model 73380 SLTA-10 Null Modem Cable, which is a DB-9 male to DB-25 male
null modem cable. This and other cables used with the SLTA-10 Adapter are described in detail in
the chapter.
Attaching the SLTA-10 Adapter to a PC
Most PC serial I/O ports have a 9-pin male DB-9 connector, although some have a 25-pin male DB25 connector. Most serial I/O ports are hard-wired as DTE devices.
If connecting to a PC or modem equipped with a DB-9 connector, then use a straight-through cable
with one end terminated with a DB-9 male connector and the other end with a DB-9 female
connector. Plug the male end into the SLTA-10 Adapter and the female end into the serial I/O
port.

If using a PC or modem equipped with a DB-25 connector, then use a cable equipped on one end
with a DB-25 female connector and a DB-9 male connector on the other end. Plug the male DB-9
connector into the SLTA-10 Adapter and the female DB-25 connector into the PC.

Attaching the SLTA-10 Adapter to a Network
The network connector for the SLTA-10 Adapter is an orange two-conductor block type. Use the 2pin conductor that comes with the SLTA-10 Adapter to connect to the twisted-pair network.
If connecting to a network which currently has an RJ-45 type connector, only the wires attached to
pins one (1) and two (2) of the RJ-45 connector are needed. These are the wires that need to be
stripped, inserted, and screwed into the SLTA-10 Adapter terminal block (J1). See figure 9 for a
diagram of the RJ-45 Terminal Block.

Configuring the SLTA-10 Adapter Hardware
There are eight configuration switches on the SLTA-10 Adapter's switch block (S1). These inputs
are read by the SLTA-10 firmware to configure or enable features. Figure 10 shows the factory
default settings for the SLTA-10 Adapter. Changes to the switch configurations will not occur
until the power is cycled on the SLTA-10 Adapter. The switches are read immediately after a
power reset.
The NSI switch selects between the legacy SLTA-10 MIP mode and a serial Network Services
Interface (NSI mode).

Figure 11 SLTA-10 Adapter Link Protocol Switch1 / CFG3
Switch1 / CFG3 controls the network interface link protocol used between the SLTA-10 Adapter
and a local host, when in MIP mode. For NSI mode, leave this switch in the default position. Two
link protocols are available for the SLTA-10 MIP mode: the SLTA-10 Adapter ALERT/ACK link
protocol and the buffered link protocol.
The ALERT/ACK link protocol is designed for host computers that cannot accept asynchronously
occurring streams of serial data at high speed. For example, a PC running DOS or Windows
