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.
