Figure 4.3.1 Instrument Configuration menu
INSTRUMENT NAME
Allows the entry of an alphanumeric name for the recorder, up to 20 characters long. See section 3.3.1 for text entry
techniques.
NORMAL/SAVER DISPLAY
Allows normal and 'saver' display brightnesses to be defined. Defaults are Normal = 100%; Saver = 50%.
SAVE AFTER
The number of minutes (between 1 and 99 inclusive), which are to elapse after a screen operation, before the screen
brightness changes from 'normal' to 'saver'. Default is one minute.
MODBUS ADDRESS
Allows a Modbus address of between 1 and 247 to be set up for the unit when it is acting as a Modbus slave.
MODBUS SECURITY DISABLED
When using MODBUS, it is possible, by 'checking' this field to allow a host computer to access the recorder without
its first having to supply a valid User name and Password. This box must be checked if this unit is acting as a Modbus
slave in order for the unit to be detected. Once communications have been established, Modbus security can be ena-
bled, providing that the Slave's Remote user name and password have been entered at the Master. See also section
2.2.4 of the Communications Manual.
COMMS CHANNEL TIMEOUT
Allows a number of seconds (between 1 and 999) to be entered. If none of the channels set to 'Comms' is communi-
cated with, within this period, an event source (Comms channel timeout) is set, and remains set until the next commu-
nication. An entry of 0 disables the time out.
PRESET HOUR
Enter an hours number between 0 and 23 for use with Clock Job - Preset clock.
PRESET MINUTE
Enter a minutes number between 0 and 59 for use with Clock Job - Preset clock.
Note: See section 4.7 for a description of recorder jobs, and section 4.5.1 for further details of time synchro-
nisation.
