MODEL232BSS4 B&B Electronics, MODEL232BSS4 Datasheet - Page 12

• Manufacturer Part Number: MODEL232BSS4
• Description: Buffered Smart Switch
• Manufacturer: B&B Electronics

Note: The 232BSS4 ignores the upper 4 bits of the control byte. If
the Master device is incapable of sending characters outside the
printable ASCII range, decimal 64 can be added to each of the
control bytes and the switch will operate properly.
Ignore Commands – “T” + one control byte specifying the length of
time to ignore commands.
10
Clear Receive Buffer
Ports to Transmit or
all commands from the Master device for a specific amount of
time. This command is useful if the data coming from the Master
device may contain switching commands. By switching to a port,
then sending the Ignore Commands command, all data received
on the Master port of the 232BSS4 will be passed directly to the
selected Slave port without checking for a command sequence
until the programmed time has elapsed. The control byte at the
end of the command tells the 232BSS4 how long to ignore
commands from the Master device. This byte is ASCII “0” – “9”
(48 – 57 Decimal). Timer values for each Control byte are given
in Table 2.3.
