Communication Port Options (3 of 5)
Character Length
Possible Settings: 7, 8
Default Setting: 8
Specifies the number of bits needed to represent one character. The character length
must be set to 8 bits when using the communication port as the network communication
link.
Character length defaults to 8 and cannot be changed if Port Use is set to Net Link
and Port Type is set to Asynchronous.
7 – Sets the character length to seven bits.
8 – Sets the character length to eight bits. You must use this setting if using the COM
port as the network communication link.
Parity
Possible Settings: None, Even, Odd
Default Setting: None
Provides a method of checking the accuracy of binary numbers for the COM port.
None – Provides no Parity.
Even – Makes the sum of all 1 bits in the character and its corresponding parity bit
always even.
Odd – Makes the sum of all 1 bits in the character and its corresponding parity bit
always odd.
Stop Bits
Possible Settings: 1, 1.5, 2
Default Setting: 1
Determines the number of stop bits used for the COM port.
1 – Provides one stop bit.
1.5 – Provides one and a half stop bits.
2 – Provides two stop bits.
Ignore Control Leads
Possible Settings: Disable, DTR
Default Setting: Disable
Specifies whether Data Terminal Ready (DTR) is used.
Disable – Treats control leads as standard operation.
DTR – Ignores DTR. This may be necessary when connecting to some PAD (Packet
Assembly and Disassembly) devices.
