4.3 RS-232/422 Control
All of the functions detailed in section 3.1 are available from RS-232/422 control. Every QuadScan is operable in both
RS-232 and RS-422, but must be correctly set up for each standard. When configured for RS-422, up to 8 QuadScans
may be connected in a single RS-422 wired system. The QuadScans will react to controls that are delivered to a unique
address that is programmed into each QuadScan via the Front Panel control.
When configured for RS-232, only a single QuadScan may be attached to the RS-232 link. The default configuration is
RS-232.
4.3.1 Configuring the QuadScan for RS-232 or RS-422
Jumper JP3 on the QuadScan’s Control Interface board selects RS-232 or RS-422. Depending on the configuration of this
jumper, the DB-9 communications connector located on the front panel of the QuadScan will accept either RS-232 or RS-
422.
Figure 4 indicates the positioning of Jumper JP3. In the case of RS-422, the user has the additional choice of selecting a
120 Ohm termination.
