Page 5: Introduction
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. -

Page 9: Configuration Cable
Configuration Port A Most configuration of the jrN is performed by interacting with the Menu Hardware Options screens presented through Port A but there are two sets of hardware jumpers that determine some properties of Port A. Reference should be made to the diagram on pages 6 and 8 when making any changes to the jumpers. -

Page 11: Configuration Bytes
Configuration Configuration Bytes The current generation of Diplomat jr s grew from a generation that had lots of configuration switches on the PCB to set up options. This required taking the lid off the box to make changes and in addition the switches occupied valuable PCB space that could be better utilised for extra functionality. - Page 12 Configuration The meaning of the bits in Configuration Byte A are given in the following table. Name Description of Switch BHWPNG [0] - Ignore ICMP ECHO notifications. [1] - If an ICMP ECHO message is received on Port B and Configuration Byte B BEXREP=1 then output a BEL character on Port A.
- Page 13 Configuration The meaning of the bits in Configuration Byte B are given in the following table. Name Description of Switch BPEER [0] - Enforce Client/Server relationship in TCP [1] - Allow Client/Client sessions in TCP BTCPUD [0] - Use the TCP protocol [1] - Use the UDP protocol BSEXY [0] - New Session(SYN) attempts must come from the same Host as the...

- Page 16 Configuration In the above screen the Diplomat has been configured as a Server. In a later screen the slight differences when it is configured as a Client will be obvious. The Ethernet Address is unique to the unit and cannot be changed. It is displayed for information only.
- Page 17 Configuration When the Diplomat is configured as a Client there are two port addresses required. This time the Service Port is the Server Port number that the Diplomat will try to establish a connection with on the Server and the Client Port number is the Diplomat’s own local port ID.

Page 18: Remote Configuration
Configuration As we mentioned earlier, the design of the menu system enables auto- matic configuration changes under the control of a local computer sys- tem very simply. For example suppose that the configuration change required was to make the Diplomat jrN a UDP Server on port 2000 just for the day. - Page 19 Configuration The remote jrN will also perform a soft restart after saving the new configuration and any existing TCP connection will be lost. It must be emphasized that typing Return when in the remote Main Menu is necessary for new configuration values to be stored, but typing CTRL/P at any time will return to the Host jrN Main Menu.

Page 20: Operation
Operation Normal Operation As long as the Diplomat jrN is properly configured and is not in Network Monitor mode it is in the Normal Mode of operation. It will process the following Ethernet message types: ARP messages addressed to the local IP address RARP messages containing the local Ethernet address ICMP messages addressed to the local IP address UDP messages addressed to the local IP address and the local port or... -
Page 21: Udp Client/Server
Operation UDP Client/Server When configured as a UDP Server the Diplomat jrN will wait until a UDP packet is received from a remote host which is addressed to the local IP address and Server Port held in the jrN. The Diplomat jrN cannot send any data over the network until it has received a packet containing a Source Port address for it to use as a return address. -
Page 22: Closing Tcp Sessions
Operation Closing TCP Sessions In both modes the user has control over the closing of active TCP sessions. If switch BHWDIS in Configuration Byte A is set then the signals on DSR (pin 6) and DCD (pin 8) on Port A will be dropped for 1 second when the session is closed from the remote host. -
Page 23: Controlling The Flow Of Data Page
Operation Controlling the The Diplomat jrN has been designed to be flexible so that it can be used flow of data in situations as yet unknown. It is therefore not practical to say how it should be set up because we do not know precisely what it will be used for. -
Page 24: Transparent Mode
Operation Most important is to make sure the setting of switch BXON correctly reflects the way DC1 and DC3 characters are handled by the system. If switch BXON is cleared and the connected device uses XON/XOFF flow control then any DC1 or DC3 characters sent to the Diplomat jrN intended for flow control will be sent to the remote host which is prob- ably not what was intended. -

Most trouble shooting will revolve round the units relationship with the network it is connected to. -

If a reply is received this shows that at least the low level drivers at the Remote Host are functioning. -
Page 29: Error Messages
Trouble Shooting and Error Messages Error Messages There are three types of messages, those originating from error conditions detected by the Diplomat jrN itself and those that are reported by the network and are translated into a readable text for the user. Internal error messages are bracketed by three asterisks and remote messages by three plusses. -
