2.5.4Serial I/O (Remote)

The DP570 will allow remote control via the front-panel (RS-232) or rear-panel (RS-

485) ports. See Section 6.4 for further information. The serial I/O connections can also used for software upgrades.

2.5.5General Purpose I/O

The DP570 has a 37-pin female D-connector for the GPI/O connections. Most of these connections are user definable, but there are a few standard connections.
