The following sections cover use of PC commands. These may be sent to the instrument via a
simple terminal program
38
, through some programming interface, from Excel™ (or similar
program) or interactively with a dedicated program (such as ULOG – supplied by ASL).
The PC symbol

will be briefly displayed when a command is received.
8.3.1 Remote mode (local lockout)
The instrument may be set into Remote mode to prevent problems with simultaneous control
from a PC and from someone using the front panel keys. In Remote mode, the instrument can
only be controlled over the interface since the CTR5000’s front panel keys are locked out. To
enable Remote mode, the instrument must be sent a Local lockout (L) command. The PC
symbol

will be permanently displayed in remote mode. Remote mode is cleared when
the instrument is switched on.
It is not necessary to be in remote mode to use any of the PC commands, but care must be
taken not to inadvertently change settings.
8.3.2 Commands and Syntax
The following commands can be sent to the instrument - all commands are composed of
single letters, followed by none, one or two single digit parameters or letters (except the
switchbox commands, which have 2 alphabetical characters followed by 2 digits).
Commands are terminated by a carriage return character <CR> and/or a line feed <LF>
character.
Response data are always terminated by a carriage return and line feed character
<CR><LF>.
The instrument responds to all illegal or unrecognized commands with error 5.
A PC icon will flash briefly on the CTR5000 display when data are received. The icon will be
continuously present when the instrument is in remote mode.
For ease of use, new commands, new details and additional information, not present with the
F250, are coloured blue.
