1. Introduction
The NET232jr was designed to be the smallest serial to Ethernet adapter available. The design allows for
different configurations for the physical connection to the serial port. This document details the various
hardware options available.
1.1 Hardware Design
There are two hardware versions of the NET232jr. One unit is designed to work with 3.3VDC power input
and the other is designed to work with 5VDC.
The 3.3VDC version is designed with the serial port signals terminating with an RJ45 connector. This
version can also be ordered without the RJ45 connector, which allows the option of a custom cable.
The 5VDC version is designed with the serial port signals terminating with an RJ12 connector. This version
can also be ordered without the RJ12 connector, which allows the option of a custom cable.
The following picture shows the NET232jr-RJ45 on the LEFT, and the NET232jr-RJ12 on the RIGHT.

1.2 Overview of Options
Both hardware versions were designed to provide for multiple configurations of the serial interface. The
RJ12 and RJ45 connectors provide a fast and secure method of cable connection. You can make your own
cables and connectors, or Grid Connect can provide a custom solution.
1.2.1 NET232jr-RJ45 Cable Options
RJ45 cables are easy to make and inexpensive to purchase. They come in almost any length and various
colors. There are many types of RJ45 adapters available, including RJ45-DB9 M/F and RJ45-DB25 M/F.
The following picture shows a NET232jr-RJ45 with a short RJ45 CAT5 cable and an RJ45-DB25 Female
adapter. Remember that the interface cable must also provide 3.3VDC.
Figure 1-NET232jr-RJ45, RJ45 Cable, RJ45/DB25F Adapter
The NET232jr-RJ45 can be ordered without the RJ45 Serial connector. This design allows for different
cable lengths and cable connectors, such as RJ45, DB9 M/F, DB25 M/F, or stripped and tinned leads.
The following picture shows a NET232jr-RJ45 with a short RJ45 cable permanently connected to the
module. The cable provides 3.3VDC and interface signals.

1.2.2 NET232jr-RJ12 Cable Options
RJ12 cables are easy to make and inexpensive to purchase. They come in almost any length but colors are
limited. They are usually grey but some colors are available. There are many types of RJ12 adapters
available. They are generally referred to as Modular Adapters.
The following picture shows a NET232jr-RJ12 with a short RJ12 cable and a RJ12 to DB9 Female modular
adapter. Remember that the interface cable must also provide 5VDC.
Figure 3-NET232jr-RJ12, RJ12 cable, RJ12-DB9F Adapter
The NET232jr-RJ12 can be ordered without the RJ12 Serial connector. This design allows for different
cable lengths and cable connectors, such as RJ12, RJ45, DB9 M/F, DB25 M/F, or stripped and tinned leads.
The following picture shows a NET232jr-RJ12 with a very short cable and DB9 Male connector. The cable
provides 5VDC and the interface signals.
Figure 4-NET232jr-RJ12 with DB9 Connector
Grid Connect can have a custom cable made for a specific application. The following drawing shows a
custom molded cable with and external power connector. The custom cable snaps into the NET232jr-RJ12
connector. Power for the NET232jr is provided by the external power jack.

1.3.1 NET232jr-RJ12 Cables
The following picture shows a NET232jr with a custom molded RJ12 Cable Adapter. This adapter has an
RJ12 connector and DB9 Female connector. The adapter and NET232jr are connected together with a short
length of 6-conductor flat cable. The power connector is molded into the DB9 connector. This is similar to
the cable supplied in the NET232jr Development Kit.
You can make your own custom cable by using RJ12 flat cable and connectors, and Modular Adapters that
convert RJ12 signals to other connectors such as DB9 Male. The following drawing shows how to make an
RJ12-DB9Male cable assembly. There is a list of Modular Adapters, parts, cables, and tools at the end of
this document.

1.4.1 Using CAT5 Patch Cords
The standard NET232jr-RJ45 comes with the RJ45 connector already installed. A standard CAT5 patch
cable can be used as the interface cable connector. Make sure they are straight through cables and not crossover cables.
Figure 9-NET232jr-RJ45 with Patch Cord
1.4.2 Custom Cable
You can order the NET232jr-RJ45 without the RJ45 connector. You can make a cable from standard CAT5
cable. One end has a standard RJ45 connector and the other end wired to the circuit board according to the
following drawing. This allows you to make a custom length to suit your application.
