Configuration
21
RS-485 Mode
If the port is used for RS-485/422, configure the mode to be
either two wire or four wire. If the port is jumpered for RS-232
operation, this setting has no effect.
Hardware Handshaking
This option is used to enable or disable RTS/CTS Handshaking
typically used with half-duplex modems. Do not confuse this
with hardware flow control. The following 4 paramters control
the timing and are only valid when handshaking is enabled.
Delay after RTS Active
This parameter sets the minimum amount of time to delay after
asserting RTS before checking the state of CTS.Set to a value
between 0 and 5000 msec (5 seconds).
Wait CTS Active
This parameter sets the maximum amount of time to wait for CTS
to go active. If CTS does not go active within this time period,
the transmission will be aborted.
Set to a value between 0 and 5000 msec (5 seconds).
Delay After CTS Active
This parameter sets the minimum amount of time to wait after
CTS goes active before transmitting the data. Set to a value
between 0 and 5000 msec (5 seconds).
Delay Dropping RTS
This is the optional delay that occurs between the end of data
transmission and lowering RTS. Set to a value between 0 and
5000 msec (5 seconds).
