<h3><a name="itc4">ITC-4</a> and ITC-503 Temperature Controllers</h3>

These temperature controller were fairly popular at SINQ. They are
manufactured by
Oxford Instruments. At the back of this controller is a RS-232
socket which must be connected to a Macintosh computer running the SINQ
terminal server program via a serial cable. Please make sure with a different
Macintosh or a PC that the serial line is OK and the ITC-4 responding before
plugging it in.
