Table 5 Character Times at the Supported BAUD Rates

4.2.5 RTS Off Time

This parameter specifies the time, in milliseconds, that the RTS line will remain asserted after the last character has entered the SIO output buffer. The value configured here will be dependent on the speed and the type of communication hardware used. Refer to Table 5 for a list of character times at the supported baud rates.

☞NOTE: If either RTS On Time or the RTS Off Time are configured to be non-

zero, the RTS Off Time must be configured to at least one character time. If modem signals are not desired, set both the RTS On Time and RTS Off Time to 0.

4.2.6 Intercharacter Timeout

This parameter specifies the maximum time, in milliseconds, that the BECO2200 DCA should wait for the next character in the reply message. The value configured here will be dependent on the speed and the type of communication hardware used, and must be at least one character time. Refer to Table 5 for a list of character times at the supported baud rates.

☞NOTE: Since the BECO2200 DCA uses the Intercharacter Timeout to determine

the end of a variable length message, this parameter should be configured to no more than 2 to 5 character times. Configuring this value with too large of a value may impede the speed at which the BECO2200 DCA polls the devices.

4.2.7 Remote Reply Timeout

This parameter specifies the maximum time, in milliseconds, that the BECO2200 DCA should wait for the receipt of a complete device response. The value configured here will be dependent on the speed and the type of communication hardware used. The value must be large enough to receive the maximum message length possible from the BECO2200 device. The maximum message length is 255 characters. Refer to Table 5 for a list of character times at the supported baud rates.
