INTRODUCTION
This document discusses the model 138 Programmable Serial
Gateway — EnernetWorks™ Network Adapter (PSG). The
PSG Network Adapter provides a bridge between an
EnernetWorks™ 900MHz mesh network and an EIA-232
network interface device. EnernetWorks™ is a proprietary
mesh network protocol used to create connectivity among T9000
wireless thermostat Remote Control Nodes (RCN) and other
licensed devices manufactured by ENERNET Corporation. A
network interface device or other EIA-232-capable serial device
connects to the PSG Network Adapter. A single model 138
Programmable Serial Gateway Network Adapter can
accommodate data traffic from as many as 500
EnernetWorks™ capable nodes.
MESH NETWORK OVERVIEW
A simple overview example of EnernetWorks™ is shown in
Figure 1. A network interface device communicates with an
arbitrary number of targeted EnernetWorks™ capable nodes
via one or more PSG Network Adapters. Each node in the
network can be individually polled for status and other data, sent
operational commands or set to automatically report changes in
conditions and/or operating status. Communications can be
further extended by routing onto a power line carrier network using
the Model 125 wall-plug RF/PLC Bridge.

INTERCONNECTION
The PSG Network Adapter is powered by the supplied 9-volt DC
wall-plug power source. A standard 9-pin serial cable connects
the PSG Network Adapter to a network interface device. (Refer to
Figure 2.)
POSITIONING
Locate the PSG Network Adapter within RF mesh network range
of one or more EnernetWorks™ nodes to ensure sufficient
connectivity. Some installations may require the optional external
dipole antenna. (See RF COMMUNICATION TEST section
below.)
CONFIGURATION SWITCHES
Configuration switches set one of 256 possible network addresses
into the PSG Network Adapter in a binary fashion. See Figure 3
for Configuration Switch location and Table 1 for address setup. If
the selected network address is already in use, the Network
Adapter will light the Service LED indicating possible network
contention.

MULTIPLE PSG NETWORK ADAPTERS
If multiple PSG Network Adapters are needed because of a large
number of network nodes, or in the case of two or more
independent networks comingled within overlapping RF coverage,
configuration dip switches must be set to different domain
addresses. RCN’s and any other EnernetWorks™ capable
devices must also be set to the same network address. (See
specific device Operators Manual for details.)

TESTING
The PSG Network Adapter operates in two protocol modes –
binary and ASCII. Binary mode is used only by applications such
as the Monet™ suite, and enables detailed, automated control and
monitoring of target nodes on the mesh network. Refer to the
EnernetWorks™ Mesh Network API Guide for details.
ASCII mode is used primarily to test and configure the PSG
Network Adapter via the EIA-232 port. Perform the following
steps to configure the PSG Network Adapter:
1. Make sure PSG Network Adapter is unpowered
while making connections or changing
configuration switch settings.
2. Set building address per instructions on page 6,
Configuration Switches.
3. Set network interface device to 57600bps, 8 bits,
no parity 1 stop bit, flow control = NONE.
4. Connect 9-pin serial cable to the PSG Network
Adapter EIA-232 port and to your network interface
device.
5. Connect power cable to PSG Network Adapter. It
immediately sends the message,
“EnernetWorks™ Serial Gateway, Ver.
<firmware version #>”
6. You can now execute the following PSG Network
Adapter commands as needed:
CMD
?Display firmware version number
B or b Set building address. Same as setting DIP switches.
S or s Toggle serial diagnostic mode. Certain mesh network
responses are transmitted through the EIA-232 port in
ASCII format.
Displays Serial Diagnostic Mode= OFF/ON
R or r Reset PSG Network Adapter. Read the configuration
switch setting.

X or x Enable/disable ASCII responses. Used to squelch any
ASCII asynchronous responses (i.e. send only binary
mode). This is reset by command R
Note: PSG Network Adapter transmits certain status
messages asynchronously, unless the X command has
been issued:
Line Break Detected
RF COMMUNICATION TEST
For proper operation, the PSG Network Adapter should be placed
within RF range of at least one other EnernetWorks™ node.
For maximum reliabilty it should link to at least four neighbors.
The following test requires connection to a network interface
device (see previous section, TESTING):
1. Make sure Configuration / Building address is set per
instructions on page 6, Configuration Switches.
2. If you are using the monopole helical antenna (standard
supplied configuration) place the PSG Network Adapter
in its proposed location. Then go to step 4.
3. If you are using the dipole/cable antenna option, place
only the antenna in its proposed location. Screw the
other end of the cable to the PSG Network Adapter
antenna connector. (WARNING: HAND TIGHTEN
ONLY, DO NOT USE TOOLS. Excessive force can
damage the connector!)
4. Issue the “N” command to send a neighbor count
command on the mesh network. PSG Network Adapter
responds with the message Neighbor Count = XX,
where XX is the actual number of EnernetWorks™
nodes heard.
5. If the Neighbor Count is less than 4, consider relocating
the PSG or antenna closer to other
EnernetWorks™ nodes.
