7. A command must be sent to the constant temperature equipment
to test communication. For example, TYPE. Type the command and
press [Send ASCII].
If the connection is operational, the constant temperature equip-
ment acknowledges the command.
4.7.4 Data transfer rate
The data transfer rate cannot be precisely defined. It depends on a variety of
dierent factors:
n Are the constant temperature equipment ( with the Ethernet interface)
and the control station/PC on the same network?
n Are the control station/PC and constant temperature equipment con-
nected wirelessly (WiFi) or through a cable?
n What is the load on the network?
Generally commands can be sent to the constant temperature equipment
every 500 ms. For WiFi connections the period could exceed 1 s. A new
command can only be sent if the previous command has been acknowledged
by the constant temperature equipment.
