RS-232 OUTPUT and BAUD RATE SELECTION

RS-232 OUTPUT

The 2091 can also be configured to convert the Data Line input
to RS-232 code which can be sent to receivers via a modem or
a 1983CS536, RS-232 to Control Code converter, or connected
directly to a 1640 "S" Series Receiver (e.g., 1641S-1).
The RS-232 connector is an 8-pin modular phone type
connector, marked COM on the rear panel of the unit. The
breakout box that is connected to this port has the pinouts
shown in Table 2. See figure 5 for the pin locations on the
breakout box.

BAUD RATE SELECTION

The 2091 has four selectable baud rates: 1200, 2400, 4800, and
9600. By setting a baud rate, the code converter will be
placed into the RS-232 mode and Control Code conversion
will no longer take place.
To select a baud rate:
1. Unplug the code converter.
2. Remove the seven screws which hold down the top cover.
3. Find the eight position dip switch which is located at the
rear of the main printed circuit board (marked S5, see
Figure 6).
4. Set the baud rate according to Table 3.
5. After making a baud rate selection, replace the top cover.
6. Wire the breakout box as diagramed in Figure 5.
Now you can "POWER UP" the unit.

CAUTION - Due to the presence of non-insulated
components with hazardous voltages, the
following internal adjustments should be
performed by qualified service personnel only.

5 1,2,3,4,6,7,8
Note: Positions 1 - 4 on the 8-position dip switch are
always set to OFF. (Except for Filter Selection, as
described below). If any of the above baud rate DIP
switches (positions 5 - 8) are set to ON (RS-232 mode), the
conversion of DATA LINE code to Control Code will not
function, and only RS-232 is generated via the COM port.

FILTER SELECTION

When the 2091 is installed into existing systems using older
model 1680 receivers, there may be erratic control of the
pan/tilt units. This is due to the variable speed control words
sent by newer controller systems and not interpreted by the
older receivers. These words can be "filtered" out by setting
the fourth switch position of S5 to the ON position. This
setting will filter out all variable speed control words on the
Control Code or RS-232 code outputs.
