Zero client device with integrated serial or parallel ports
First Claim
1. A zero client device, comprising:
- a housing;
a transcoding processing unit, comprised in the housing, wherein the transcoding processing unit is implemented on a first circuit board, and wherein the transcoding processing unit comprises at least one Universal Serial Bus (USB) port;
one or more converters comprised in the housing and coupled to the USB port of the transcoding processing unit to facilitate communications between the transcoding processing unit and a corresponding one or more peripheral devices, wherein each converter of the one or more converters is configured to convert between USB protocol and one of;
RS-232 communication protocol;
RS-485 communication protocol;
ora parallel communication protocol;
wherein the transcoding processing unit is connected to the one or more converters via a secondary communication channel that is used to implement one or more of;
power management for the one or more converters;
gathering performance metrics from the one or more converters;
ormanagement and configuration of the one or more converters; and
a communications processing unit, comprised in the housing and coupled to the transcoding processing unit, wherein the communications processing unit is implemented on a second circuit board; and
wherein the zero client device has no user-modifiable storage medium;
wherein the communications processing unit is configured to;
determine an identifier of a server to which connection is desired; and
provide a network communication channel to the transcoding processing unit for accessing the server;
wherein the transcoding processing unit is configured to;
instantiate a zero client session with the server through the network communication channel provided by the communications processing unit;
wherein the transcoding processing unit is further configured to;
receive first input data from one or more human interface devices;
receive second input data from at least one non-USB peripheral device via at least one of the one or more converters;
encode the first and second input data, thereby generating encoded input data; and
provide the encoded input data to the communications processing unit for transmission over the network to the server via the zero client session;
wherein the communications processing unit is configured to;
receive the encoded input data from the transcoding processing unit;
transmit the encoded input data over the network to the server via the zero client session;
receive first and second output data from the server over the network via the zero client session; and
send the first and second output data to the transcoding processing unit;
wherein the transcoding processing unit is further configured to;
receive the first and second output data from the communications processing unit;
decode the first and second output data, thereby generating corresponding first and second decoded output data;
send the first decoded output data to at least one of the one or more human interface devices; and
send the second decoded output data to the at least one non-USB peripheral device via at least one of the one or more converters.

Abstract
System and method for zero client communications. A zero client device includes a housing, and in the housing, a transcoding processing unit (transcoder) and a communications processing unit coupled to the transcoder. The transcoder is configured to receive input data from human interface device(s), encode the input data, and provide the encoded input data to the communications processing unit for transmission over a network to a server. The communications processing unit is configured to receive the encoded input data from the transcoder, transmit the encoded input data over the network to the server, receive output data from the server, and send the output data to the transcoder. The transcoder is further configured to receive the output data from the communications processing unit, decode the output data, and send the decoded output data to at least one of the human interface devices.
