Annex Terminal Servers

Introduction

1.0 Introduction
The Franklin Data Collection System (FDCS) uses Xylogics Micro Annex
XL and Remote Annex 2000 terminal servers to provide the interface
between the RS232 outputs from various instruments and the data acquisition computers. The R2000’s have the advantage ofbeing self-booting,
which means that they can be used without having to power-up one of the
Suns.
This manual documents the aspects of terminal server installation and
management that apply to the Southern Surveyor installation. It is not
intended as a How to do it manual. For that you should go to the appropriate, manufacturer-supplied documentation.
The first three sections of this manualdescribe how to configure and monitor Annex ports. All Southern Surveyor computing and electronics personnel should familiarise themselves with these procedures.
The later sections provide background & reference information about
installing Annexes, setting up printer queues on Annex ports, cabling
details etc. Browse through these sections, so that you know what they
contain, but only studythem in detail when you have to.

The reference section of the former gives a very thorough treatment of
the configuration commands and options.

Data acquisition from Annex ports

2.0 Data acquisition from Annexports
Two steps are required to make an Annex port (or service) accessible to
the data acquisition programs:

•
•

2.1

The Annex and the port to be used must have been correctly set up.
This is described in the next section.
If you are adding a new service, or an existing service is being moved
to a new port, it will probably be necessary to edit the service data
base. This databaseprovides the link between the logical name the
software uses to describe a port (eg ‘ctd_input’) and the annex and
port to which this refers.

Editing the service database
The service database is maintained in the file
/opt/fdcs/etc/mdb/service.rel.
Always make the changes to the copy on ss-user and propogate the new
version to the other hosts. It is best to use a console as the Xterminalkeyboards work a little differently.
1.

Make sure you are logged into ss-user & type
service_edit

Just type in reponse to the request for the Encryption
Password (there isn’t one)
2. Use the A command to add a new entry.
3. To modify an existing entry
• Locate it with the G command, or by typing F followed by a series
of N’s to step through to the correct location.
