Comm port |
The comm port and serial protocol to use for data transfer. |
|
Bits per sec |
The baud rate (speed) for data transfer. |
|
Data bits |
The number of data bits in each character. Baudot uses 5, true ASCII uses 7. We recommend using 8, as this can be used for any type of data. |
|
Parity |
Specifies that an extra bit is to be included in the data transmission. This can be used for error detection. |
|
none |
No parity bit is sent. Error detection is handled by the communication protocol. |
|
even |
The parity bit is set to 1 if the number of ones in the set of bits is odd, therefore making the number of ones even. |
|
odd |
The parity bit is set to 1 if the number of ones in the set of bits is even, therefore making the number of ones odd. |
|
mark |
Parity bit is always set to the mark signal condition (logical 1). |
|
space |
Parity bit is always set to the space signal condition. |
|
Stop bits |
Bits sent at the end of every character to signify the end of the character in the data transmission. Normally, 1 stop bit is used. |
|
Rear mode |
The operating mode for a data port that supports more than one mode. For example, RS-422 or RS-485. |
|
Status |
The current status of device. |
|
Listening |
Lit (green) when the device is operational and waiting for data to arrive. |
|
Clear Counters |
Resets all the counters at the bottom of the tab. |
|
Bytes In |
The number of bytes received by the device. |
|
Bytes Out |
The number of bytes transmitted by the device. |
|
Activity |
Lit yellow when data is being transmitted or received. |
