Timeout selections are equal to one character time at the

indicated baud rate. Setting the converter 9600 will

generally work at 9600 and higher baud rates. In RS-422

mode, timeouts are not required.

# To achieve these timeouts you must place a through -

hole resistor on the circuit board. See Step 5 for more

information.

If you need to support timeouts indicated with a # in

Step 4, Table 5, you must place a through-hole

resistor on the PCB. Place the resistor in the R-11

spot designated on the board. The R-11 location is

clearly visible on the PCB.
