Bit Rate – Selects transmit and receive speed. This setting is available on both the RS232 and RS485 ports.
Character Length – Selects the number of bits representing a character. This setting is available on both the RS232 and
RS485 ports.
Parity – Selects the parity bit setting that will match the far end. This setting is available on both the RS232 and RS485
ports.
Flow Control (DB9 Only) – Selects No flow control, Hardware Flow Control (RTS/CTS), or Software Flow Control
(XON/XOFF). If RTS/CTS is selected make sure that the cable you are using has those pins connected on both ends.
Many pre-manufactured cables either do not terminate these signals or else jumper them into a permanent True state.

simultaneously.
None - Indicates that a custom application and protocol has been implemented.
TCP PAD & UDP PAD - Selects the appropriate Packet Assembly and Disassembly Service.
