1. Control and Status
This section of the document describes the specifications for control and
status of the Limiter Switch Box, PMI Model No. PSD-6G18G-CD-2 via
external network (TCP/IP socket). The Network Attenuator Controller uses
an XPort Network to Serial Interface to interface the onboard
MicroController to the Network. Attached is the Datasheet and Users
Guide describing the XPort module and additional programming features.
The Limiter Switch Box, using the Default IP Address, listens on TCP/IP
Address 10.1.1.241, Port 10001 for external socket connections. Default
Network Mask set to 255.0.0.0. Gateway and DNS default set to 0.0.0.0.
Only one connection at a time is supported on the socket connection.
2. General Command Syntax
Commands are sent to the Limiter Switch Box, responses are received
from the Limiter Switch Box. All commands and responses are comprised
of ASCII characters. The Commands and Responses section of this
document provide the format and description of each of the commands and
responses. Every command must be terminated with a line feed character
(0x0a). Every command sent by the user to the Limiter Switch Box will be
followed by a response from the Limiter Switch Box to the user. The user
must wait to receive the response before sending another command. The
response can be one of two message types: a simple acknowledge
mnemonic (AK), a negative acknowledge mnemonic (NK) or a response
that contains the data associated with the command.

3. Commands and Responses
The following sections describe the various commands, responses
and their parameters. As was mentioned previously, all commands
received by the Limiter Switch Box generate some type of response –
either a simple acknowledge or with other data. A description of the
response provided by each command is discussed with each command.
Unless otherwise stated, the user must always wait until the response is
received for a command before sending another command. In the syntax
examples the “\r\n” is the carriage return and line feed.
AK –Acknowledge
Acknowledge is a response sent by the Limiter Switch Box to the user
when a command was received and processed without problems. There
are no parameters.
Example: AK\r\n
NK –Negative Acknowledge
The negative acknowledge is a response returned from the NAC when
the command received was syntactically or functionally incorrect. There
are no parameters.
Example: NK\r\n
co –Set IP Address

This command is used to manually set the IP Address, Host Bits
(Network Mask), Gateway, Port Number and DNS Server IP Address of the
Limiter Switch Box. This command takes about 30 seconds to complete
and reboot the Limiter Switch Box. Once the reboot is completed, a new
network connection can be established at the new network address.
Gateway and DNS Server addresses can be set to “0.0.0.0” if not used.
The Limiter Switch Box responds with an AK or NK.
Example: co 192.168.1.99 8 192.168.1.1 10001 192.168.1.1\r\n
