PAD Port Configuration

Port Speed

Range:

50, 75, 100, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800,

 

7200, 9600, 14400, 19200, 28800, 38400, 75/1200, AUTO

 

 

Default:

9600

 

 

Description:

Specifies the port speed in bits per second.

 

• Port speed is set by this parameter although the PAD Profile

 

Table can specify a PAD port's characteristics.

 

• When 134 is selected, the actual speed is 134.5 bps.

 

• Split speed (75/1200) can be configured only on 6500 PLUS

 

Processor and Asynchronous I/O Cards.

 

 

Auto Baud Sequence

Range:

CR_ONLY, CR_DOT_CR, TYMNET, TELENET

Default:

CR_ONLY

 

 

Description:

Specifies the character sequence used for autospeed recognition

 

for these autospeed ports:

 

• PAD ports with Port Speed = AUTO

 

• Device Parity = Auto

 

• Data Bits Per Character = 7:

 

– CR_Only: Autospeed on <CR>

 

– CR_DOT_CR: Autospeed on <CR>.<CR>

 

– TYMNET: Autospeed on the letter “a” (must be lower

 

case)

 

– TELENET: Autospeed on <CR><CR> for 1200 bps or

 

lower and @ <CR> for 2400 bps or higher

 

The speeds are supported on all PathBuilder S200 series switches.

 

The autospeeds of 14.4 Kbps, 19.2 Kbps, 28.8 Kbps, and 38.4

 

Kbps are not supported on UIO/AIO cards.

•Used to detect and adapt to the speed and parity of a terminal configured as 7 bit plus parity.

•Select CR_DOT_CR if the connecting terminal's Data Bits per Character (7 or 8) is unknown or changes

(typical for dial-in applications).
