RS-232 connector
— This female 9-pin DB-9 connector provides for RS-232 or
RS-422 remote communication. Connect a host computer or control system to this
connector for serial control of the DVS by Simple Instruction Set (SIS) commands
(see
Remote Configuration and Control
, beginning on page 48) or by the SPPCP
software (see the control program help file).
The default protocol for this port is 9600 baud, 1 stop bit, no parity, and no flow control.
Figure 8 shows the pin assignments for the DB-9 connector.

Connecting to the RS-232 CONFIG Port (Front Panel)
The CONFIG port on the front panel is an additional RS-232 connector. A host device can
be connected to this 2.5 mm TRS connector for serial RS-232 control, as an alternative to
the rear panel RS232 port.
An optional 2.5 mm cable (part number 70-335-01) can be used to connect the DVS to a
computer. Figure 9 shows the pin assignments for this cable.
