4.3.2 Connecting the TView Pro AV to communications devices
Slightly different connections schemes are required for RS-232 and RS-422 operation.
Figure 6 indicates the recommended connections from a DB-9 connector for RS-232 operation. Depending on the way
that the controlling port is programmed, other connections may work as well. The TView Pro AV has no way of handling
the RTS/CTS and DSR/DCD signals.
Figure 7 indicates the recommended connections from a DB-9 connector for RS-422 operation. In this case, a simple 9
pin to 9 pin cable will work in all cases.
