Features:
- Full-duplex RS-232: one ASCII device communication channel
- Configurable records: framing, delimiters, data type, and byte-swap choices
- Actionable diagnostics: FIFO, parity, handshake, and new-data status
1734-232ASC adds a configurable RS-232 record interface to a POINT I/O node for documented ASCII equipment.
Its 128-byte data handling, selectable delimiters, and multiple string representations let the controller receive and transmit structured serial messages.
A reliable installation records the device framing, cable shield point, terminal base, data layout, handshake policy, and expected fault response before download.
Availability of 1734-232ASC is subject to Apter Power inventory and sourcing confirmation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Baud rate: select one documented rate from 1200 through 38.4 kbit/s.
- Character format: align data bits, parity, and stop bits with the instrument.
- Shielding: use shielded cable and ground the shield at one end only.
- Signal reference: wire Tx, Rx, and signal ground to the official terminal positions.
- Receive boundary: set start and end delimiter behavior for the actual protocol.
- Data type: choose array, short string, or string consistently with the controller tags.
- Byte order: apply swap mode only when the connected data format requires it.
- Record length: keep receive and transmit payloads within the published 128-byte limit.
- FIFO flags: distinguish transmit or receive overflow from a framing problem.
- Parity status: compare the configured character format with the device protocol.
- Handshake status: review record sequencing and the selected immediate or handshake mode.
- Recovery test: prove one known receive and transmit message before restoring production traffic.
- ASCII instruments: exchange records with supported serial measurement devices.
- Barcode readers: receive delimited identification strings in a POINT I/O station.
- Serial displays: transmit documented ASCII messages from Logix logic.
- Legacy interfaces: retain an approved RS-232 device within an EtherNet/IP-accessible POINT I/O architecture.
