Introduction
Introduction TheLucidataDiplomatmodel jrN is oneof afamily of simpleconnectivity
solutions built around Lucidata’s popular Diplomat jr product. The jrN
model has been designed specifically to interface to the most common
local area network (LAN) media utilising Ethernet technology and
employing the TCP/IP transport level protocols. Despite network
technology being rather complex, Lucidata has always sought to make
its products easy to use and user friendly. We believe that our products
should just be connected up and left to do their job with little on no
intervention necessary from the user.
Tothis endmost Lucidata productsare supplied withsimple menu driven
configuration screens that can be accessed with any simple local ter-
minal or emulation. Remote configuration over the network is also pos-
sible but due to the inherent security implications of such a method it is
not the default method.
The model jrN runs the jrN-ASV firmware as standard and supports
interconnectivity between Ethernet and simple asynchronous serial de-
vices over an RS232 interface. It also has brothers and sisters that
offer RS422 (jrNV), synchronous (jrNS) and parallel (jrNP) interfaces
which run a variety of communications protocols
This manual is structured to require the minimum of reading to effec-
tively operate the
Diplomat jrN . If, as is our usual policy, Lucidata has
configured your unit for you, you will only need to read Chapter 2, Get-
ting Started Quickly, to discover what plugs into where and you will be
on the air.
If your unit is not configured yet you will need to read Chapter 3 on Con-
figuration to discover what information you need to get your hands on
before starting that process. If you are wondering why you bought a
Diplomat jrN then Chapter 4, Operation, is where we tell of all the things
thatthe jrN can doandhowto drive it. Youwillprobablywant to read this
chapter anyway. Networks can be complex things and problems can
and do arise which may generate many and varied error messages,
some coming from within the
Diplomat jrN and others from outside but
reported to the interface. Chapter 5, Trouble Shooting and Error Mes-
sages, documents these and gives probable explanations and recom-
mended courses of action. Finally Chapter 6, Technical Specification,
contains the dry detail of the hardware so you know what pins to use.

Getting Started Quickly
Whenyou holdthe DiplomatjrN in your hand sothattheDiplomat jr logo
is oriented in the normal reading orientation, the Network end is to the
left and the Serial interface is to the right. For documentation purposes
we refer to the Serial interface as Port A and the selected network inter-
face as Port B.
Port A Port A is wired as a Serial Asynchronous DCE and any cable that was
designed to connect a terminal type device to a modem using a 25 pin
male D type connector will be suitable to connect your device to Port A.
Port B Port B has a 10Base-T RJ45 connector and optionally a 10Base-2 BNC
connector. If botharepresent connection shouldbe made toonlyone of
these connectors otherwise the Auto Media Sensing will get confused
andprobably choose 10Base-2.TheAutoMedia Sensing only operates
at power-up time so changing the connector during operation will not
have the desired effect. The 10Base-T connector is wired for direct
connection to a hub using UTP cable.
Power The power lead from the mains adaptor is plugged into the socket on
the Port A end. When power is applied to the adaptor the Red LED by
thepowerconnector should light. Ifit doesnot youprobablyhaveadead
mains socket but refer to Chapter 5, Trouble Shooting and Error
Messages to discover what to do.
If you have selected the 10Base-T connector the Green LED by the
RJ45 socket should be illuminated to indicate a good link to the hub. If
not consult Chapter 5.
The jrN is now operational and should be doing what was expected. If
there is traffic on the network then the Yellow LED by the RJ45 connec-
tor will be flashing.
IfthejrN has beenconfigured asaServerthenit will just waituntilsome-
one makes a connection over the network. If it is configured as a Client
then sending a single character to Port A will cause the jrN to attempt to
make a connection to the remote server defined in its configuration.

Configuration
Most configuration of the jrN is performed by interacting with the Menu
screens presented through Port A but there are two sets of hardware
jumpers that determine some properties of Port A. Reference should be
madeto the diagram onpages6and 8 when makinganychangesto the
jumpers.
Data Rate Thedatarateof Port Aisselectedbychoosingthe positionofthejumpers
on links L4 and L5.The default speeds are 9600 and 19200bps but the
clocks T1 and T2 may be configured differently by setting the
Configuration Byte D (See later section). The receive speed is selected
by link L4 and the transmit speed by link L5. If a jumper is on the right
most two pins (E-F) of a link then 9600 bps is selected. If a jumper is on
the left most two pins (D-E) of a link then the custom speed is selected
(by default 19200 bps).
Character Format The default character format used by Port A is eight data bits, no parity
bit and one stop bit (8N1). This can be configured differently by setting
the Configuration Byte C. (See later section)
DTR The state of the internal DTR signal on Port A will always determine
whether Port A will be able to transmit and it is not necessary for an
externalconnectiontobemadetopin20.SomeprintersprovideaREADY
signalon pin 19.Ifexternalcontrol is required, anditusuallyis, a jumper
between the right most pins (B-C) of link L2 will select pin 20 for DTR
control. A jumper between the left most pins (A-B) of link L2 will select
pin 19 for DTR control.
In addition the selected pin may be gently biased towards either ON or
OFF by jumpering link L1. Some devices will still hold DTR high enough
to appear ON even when they are powered off so by gently biasing the
pin OFF when the device is powered down DTR is correctly sensed.
Equally it may be desirable to keep Port A enabled all the time in which
case no links would be used on L2 and the DTR level would be
determined solely by L1. If a jumper is on the right most two pins (B-C)
of L1, DTR is biased ON and if the jumper is on the left most two pins
(A-B) of L1, DTR is biased OFF.
The DTR signal can have significant effects depending on other con-
figuration options which are described later so it is important to have it
properly configured. The default factory setting is DTR biased ON and
connected to pin 20 of Port A.
Configuration Cable If
Transparent Mode has been selected the jrN will ignore all control
characters. (see next paragraph). This would make it difficult to re-
configure the unit so the Diplomat looks for a link between Pin 8 (or 6)
and Pin 20. If it detects a link it will interpret control characters for 15
seconds before entering
TransparentMode .It is importantthatlinkL2 is
between pins B and C and that nothing is connected to pin 20 that will
prevent it being driven high and low by pin 8.
Note: The link must NOT be present for normal operation so a specially labelled
ConfigurationCableshould be made forthepurpose.

Control Characters Throughout this manual reference is made to ASCII control characters
that have special significance. They are identified variously as a key
combination eg CTRL/P, standard mnemonic eg DLE or by the ASCII
value. To make for easier reading, all referenced control characters are
definedhere.
Mnemonic Key Combination Decimal Value
DLE CTRL/P 16
ENQ CTRL/E 5
DC2 CTRL/R 18
DC1(XON) CTRL/Q 17
DC3(XOFF) CTRL/S 19

Main Menu All other configuration is done by invoking the Main Menu. Under most
circumstances, the exceptions will be described later, typing CTRL/P
(that is holding down the CTRL key and typing P) will cause the Main
Menutobedisplayed.CTRL/PisASCII value 16 decimal. Theinteraction
with the menu system might be considered rather old fashioned in this
Windows World but there is a good reason why it was designed this
way.Basicallyit makesiteasytoconfigurethejrNfrom a programrunning
on any computer by simply sending a string of significant characters to
PortAwithoutwaitingfor any response. In factif the computerfirst sends
a DC3 character (ASCII value 19 decimal) then no responses will be
returned to the computer at all. When the
Diplomat has finished
interpreting the commands it will perform a soft start and clear the flow
control blocking flag.
