# Serial

Used to set parameters related to the device's two serial ports. COM1 is RS-232 only and COM2 is RS-232 and RS-485.

## Basic

These are the most often used set of serial parameters.

Baud Rate | Baud rate in bits per second (bps). Most common is 9600 bps.
Parity | Type of parity. N = no parity, O = odd parity, E = even parity. Most common is 'N'.
Data | Number of data bits. Only 8 Supported.
Stop | Number of stop bits. Most common is 1.
RS-485 | COM2 supports both RS-232 and RS-485. This option is used to enable two wire RS-485.
RTS Keying | Used to enable and RTS keying.
Key Delay | Milliseconds to activate RTS prior to sending the message.
EoT Delay | Additional delay in milliseconds used to mark the end of a transmission. Modbus standard is 3.5 character times or approximately 4ms at 9600 baud.

## Modes

Splitter Mode Common Port | Serial data that enters the non selected ports will be directed to the selected port. data that enters the selected port will be directed to both of the non selected ports. If no port is selected then data will not pass from one port to another. CONFLICTS with multipath telemetry.
Enable Telemetry | Enables IO to IO messaging on the port.
Multipath Telemetry Enable | Allows IO to IO messaging to use multiple communication paths. CONFLICTS with splitter mode.
Multipath Telemetry Synchronization Timeout | Timeout to allow IO to IO to resume updating in the event of synchronization loss.
