4.3.1 Configuring the TView Pro AV for RS-232 or RS-422
Jumper JP3 on the TView Pro AV'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 rear panel of the TView Pro AV will accept either RS-
232 or RS-422.
Figure 5 indicates the positioning of Jumper JP3. In the case of RS-422, the user has the additional choice of selecting a
120 Ohm termination.
