<Control>
<Remote>
To operate a DNA Engine Tetrad 2 cycler in remote mode (i.e., from a desktop computer),
select <Remote> from the <Control> menu. The Remote Mode window will appear on the
screen.
Select the Syntax Checking check box to filter out any commands that do not conform
to the PTC Remote Command Set syntax. (Contact Bio-Rad Technical Support for the
latest syntax of the remote command set.) Attach a null modem serial interface (RS-
232) cable to the RS-232 port connector on the back of the DNA Engine Tetrad 2 cycler.
Connect to either COMM1 or COMM2 on a PC, or the serial port on a Mac. The cycler
is now ready to be run in remote mode.
Select the Auto Remote check box to direct the DNA Engine Tetrad 2 cycler to auto-
matically enter remote mode upon subsequent power up. This feature is particularly
useful if you consistently control the DNA Engine Tetrad 2 cycler using a desktop
computer. It eliminates the need to select <Remote> after every power up.
To disable the auto remote feature, deselect the check box (see the warning below).
The cycler will now power up in standard operation mode.
Important!
No protocols can be running when entering remote mode.
Important!
Do not exit remote mode while a protocol is running! If a protocol is
loaded and run remotely, ending the remote session by exiting the Remote Mode
window will cancel this protocol. A confirmation screen will ask you to confirm your
intent to exit the Remote Mode window.
