*1 When the default settings are used, the Baud Rate, Start Bits, Data Length, Stop Bits, Parity Yes/No, and Parity
Even/Odd settings are disabled. To specify settings other than the default settings, apply user settings.
Default settings are Baud Rate: 9,600 bps, Start Bits: 1 bit, Data Length: 7 bits, Parity: Even parity and Stop
Bits: 2 bits.
*2 With CTS control, turn ON the request to send (RTS) signal before the Serial Communications Unit starts to
send, and be sure the clear to send (CTS) signal is ON before the Serial Communications Unit sends data.
When there is no CTS control, turn ON the request to send (RTS) signal before the Serial Communications
Unit starts to send, and then send data without checking the clear to send (CTS) signal.
User-specified Setting Inclusion
Set whether to make the user-specified settings for port 1 or port 2. Enter the same settings as
those for the RS-232C port of general-purpose external devices connected by using a protocol
macro.
FALSE: Default; TRUE: User settings
When the default is set, the following details are set for the port and bits 00 to 04 do not need to be
set separately.
Baud Rate: 9,600 bps; Start Bits: 1 bit; Data Length: 7 bits; Parity: Even; Stop Bits: 2 bits
When user settings are specified, set bits 00 to 04 and the Baud Rate.
Setting example: 0900 hex: Serial Gateway Mode, using default settings for Port Settings and Baud
Rate.
Serial Communications Mode
Serial Gateway Mode is used, so set to 9 hex.
Start Bits, Data Length, Stop Bits, Parity, Baud Rate
Set these bits if the port setting is set to user settings. The start bit is always 1 bit regardless of its
setting.
Do no set a Baud Rate higher than 12. Doing so will result in a system error and operation will pro-
ceed using the default setting (9,600 bps). Do not set 1 or 2 hex, which are reserved for the system.
Send Delay (user-specified)
After the command is received by the Unit and converted to the specified protocol, it is not trans-
ferred immediately, but sent after the delay time is set within the following range:
0 to 30,000 [Unit: 10 ms]: 0 to 300 s (0 to 300,000 ms)
CTS Control
When CTS control is enabled, the request to send signal (RTS) turns ON and the transmission
starts after the clear to send signal (CTS) turns ON. When CTS control is disabled, the request to
send signal (RTS) turns ON and the transmission starts without checking whether the clear to send
signal (CTS) is ON.
Serial Gateway Response Timeout Monitoring Time
After a command is converted to the specified protocol and sent, the response timeout is monitored.
0: 5 s (default), Setting range: 1 to 255 (0.1 to 25.5 s)
The response monitoring time is 5 s when set to the default setting, or can be a user-specified time
set in the range 0.1 to 25.5 s by setting between 1 and 255.
If a timeout occurs, the command end code (0205 hex (Response Timeout)) is returned to the com-
mand source. If a response is received after a timeout, however, the message is converted and
returned to the command source.
