5.3 Detailed description of RS-232 commands

All commands must be terminated by a carriage return character ( E ). When more than one argument

are required, each argument must be separated from the next one by a blank or space character. Characters are not echoed back to your controlling device.

Every time a command is executed successfully by the thermometer, the “*” prompt character is automatically sent, except in case of failures when the “Errx” error code is sent instead. Do not send your next command before receiving either the “*” or the “Errx” prompt. The “[“ and “]” characters must not be typed in; they are used here for ease of reading only.

Most commands are applicable to all FOB100 models (different number of channels). When using one- channel model, the channel number [i] must not be typed in.

“b” This command returns the internal temperature of the enclosure. The temperature is returned in oC or oF unit, as specified by the “u” command.

ex:	“b:32.2 E“
“e[[-]1	[-]2 ...[-]n]”This command is not recognized by the one-channel model. Specify which channels

are enabled and read by your thermometer. Preceding a channel number with the minus sign “-” will disable that particular channel. This command is useful to ignore channels that are not currently used. Enter the channel numbers that you would like to use, each one separated by a blank character.

ex: “e-1 2 3 E“, to enable only channels 2 and 3 and at the same time to deactivate channel 1.
