Baud Rate

The baud rate is the speed of data transmission. Possible baud rates are

300, 600, 1200, 2400, 4800 and 9600 bits/sec.

Parity

Checking the parity of a transmitted byte is a way of detecting transmission

errors. Possible set-ups are:

•

Even

•

Odd

•

None

Even (odd) parity means that a transmitted byte must contain an even (odd)

number of binary 1’s. To achieve this, one extra bit — the parity bit — is

added to each byte transmitted. When “None” is selected, no parity check is

performed.

Stop Bit

The stop bit is used to terminate a transmitted character (see

Fig. 1.10

Together with the start bit, the stop bit frames the data bits and is used to

synchronise data transmission. The Monitor can use either one or two stop

bits.

Data Bit

The number of data bits determines how many bits are transmitted for every

byte of data. Possible set-ups are 7 or 8 data bits to a byte.

Handshake Method

The handshake method is the method used by the Monitor and the external

device to synchronize their transmissions. Three possible set-ups exist:

•

X-On/X-Off handshake

•

Hardwired handshake

•

None

When X-On/X-Off handshake is used, the Monitor transmits the X-Off

character (ASCII 19) when it can handle no more input data. When the

Monitor is once again ready to receive data, it transmits the X-On character

(ASCII 17) over the interface. Similarly, when the Monitor receives an X-Off

character during a transmission, it stops transmitting until it receives the X-

On character. If the X-On character does not arrive within 30 seconds, the

Monitor regards the transmission as aborted and issues a time-out warning.

In Hardwired-handshake mode, the Monitor sets the DTR control line (pin

20) off when it will accept no more data. When it is ready to receive more

data, the DTR line is set on. When the external device sets the DSR control
