The Diplomat jr family of protocol converters

Click for bigger picture

The highly successful Diplomat jr protocol converter is the economical solution for a multitude of connectivity problems.

This compact unit, with its own power adaptor has also proved extremely popular for pilot studies prior to installation of its larger rack mounted brothers.

There are many versions of this smart little box which cover a range of standard protocols, emulations and code conversions.

The Diplomat jr protocol converter has a standard 25 way D-type female connector (RS232) at each end. One is normally configured as DTE for synchronous connection to a mainframe and the other as DCE for asynchronous connection to a PC, printer or VDU. As an option, either interface can be configured as RS422, allowing modemless communication over distances up to 1 Km.

We have designed the Diplomat jr protocol converter to be adaptable, and because we manufacture it ourselves, we are always happy to quote if we do not have a model that fits your needs exactly.

This is the network version of the Diplomat jr protocol converter. It provides connectivity between Ethernet LANs and simple devices such as printers, terminals, PCs, modems etc. It can be configured by the user, via simple menus, to act as a Client or Server device or to behave as a remote Network Probe or Network Monitor. It comes supplied with its own power adaptor and user guide.

Connections

The Diplomat jrN protocol converter is fitted with an RJ45 jack for connection to 10 Base T networks using UTP cabling, and optionally a 10 Base 2 coax connector. The type of connector is automatically detected. Activity on the network is shown by a flashing yellow LED and a good 10 Base T connection by a green LED. The serial asynchronous port is a 25 pin female D-type wired as DCE for direct connection to terminals or printers. The Diplomat jrN protocol converter can also be supplied with a parallel printer port where high speed printing is required. A red LED shows when the unit is powered up.

Protocols

The Diplomat jrN supports the low level ARP and RARP protocols and the IP family of protocols (TCP/IP, UDP and ICMP). It supports the bulk of ICMP for control and diagnosis of network condition. In Server mode it can be configured to be a simple Telnet server. The setup menus may be accessed via the serial port. Built in ARP and ECHO functions can be used for Network Probe applications and a simple Network Traffic Monitor is provided. A software utility for remote configuration is also included. It also has a built in mini Firewall based on our LuciGate Firewall which enables it to be very selective about who it talks to.

Applications

Accessing a TCP/IP host computer from a simple device
Shared use of a specialist printer e.g. ticket or cheque printer
Sharing of a modem, EPROM burner, plotter, computer on the network
Use of built in diagnostic menus to investigate the network
Viewing of packets on the network using the Network Monitor mode
Connection to process controllers
Connection to any dumb serial device with a RS232 or RS422 connector

The Diplomat jrNS is the latest member of the Diplomat jr family. It enables connectivity between an Ethernet/IP network and devices running legacy frame synchronous protocols using serial RS232 communications such as IBM 2780, IBM 3780 or IBM 3270. It comes supplied with its own power adaptor and user guide.

Connections

The Diplomat jrNS protocol converter is fitted with an RJ45 jack for connection to 10 Base T networks using UTP cabling, or optionally wih a 10 Base 2 coax connector . Activity on the network is shown by a flashing yellow LED and a good link is indicated by a green LED. The serial synchronous port is a 25 pin male D-type wired as DTE for direct connection to synchronous DCEs. A red LED shows when the unit is powered up.

Protocols

The Diplomat jrNS supports the low level ARP and RARP protocols and the IP family of protocols (TCP/IP, UDP and ICMP). It supports the bulk of ICMP for control and diagnosis of network condition. In Server mode it can be configured to be a simple Telnet server. Built in ARP and ECHO functions can be used for Network Probe applications. The synchronous protocol supported by a particular model is determined by the firmware installed in the EPROM. Configuration is by a PC based software utility or by another remote device. It also has a built in mini Firewall based on our LuciGate Firewall which enables it to be very selective about who it talks to.

Applications

Providing a synchronous dial-up resource to the network
Providing connectivity to retail cash registers, eliminating leased lines
Providing connectivity to ATM machines, eliminating leased lines
Use of built in diagnostic menus to investigate the network
Enabling UDP/TCP streaming over VSAT satellite links
Control of synchronous dial-up modem banks
Support of strange and wonderful synchronous data streams
Many custom models available which might already meet your requirements
