Overview Manuals N-AT Role Software Set Bus Checks Applications

Features:

  • N-AT identity: board silkscreen and labels define the interface role.
  • Local-bus connection: system records link OS 525 with the CS 275 20 m bus.
  • Software boundary: programmed-device versions belong in the replacement record.
The N-AT marking connects the board identity to its documented TELEPERM M system role.

EPROM labels and switch positions should be recorded independently from the hardware catalog number.

Installed slot and bus topology provide the final context for configuration comparison.

  • OS connection: N-AT supports the documented OS 525 path.
  • Local bus: the interface addresses the 20 m CS 275 local bus.
  • System context: retain the TELEPERM M topology drawing.
  • Exact board: use 6DS1222-8BA as the procurement identity.
  • EPROM labels: record every visible version and position.
  • Switch positions: photograph configuration switches before removal.
  • No blind transfer: do not copy programmed devices without an approved procedure.
  • Archive: keep software labels with the cabinet service record.
  • Connector condition: inspect the card edge and mating slot.
  • Topology: verify the intended OS 525 and CS 275 connection.
  • Startup state: review system diagnostics after controlled power-up.
  • Communication proof: confirm expected local-bus data before release.
  • OS 525 integration: connects the operator-system path to CS 275.
  • Local-bus maintenance: supports service of the 20 m interface.
  • Legacy DCS repair: preserves board and software identity.
  • Topology recovery: documents slot, EPROM and switch evidence.
Description
The N-AT marking identifies 6DS1222-8BA as the TELEPERM M local-bus interface used between OS 525 equipment and the 20 m CS 275 local bus.

Versioned programmed devices visible on 6DS1222-8BA belong to the software record and should be tracked separately from the catalog number.

A dependable match for 6DS1222-8BA includes the installed slot, OS 525/CS 275 topology and software labels; Apter Power can assist with exact-board sourcing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What system link is 6DS1222-8BA designed to provide?
It serves as the N-AT interface between OS 525 and the 20 m local bus of CS 275, so both ends of that path must be present in the installed system.
Can 6DS1222-8BA be used as a general-purpose serial-interface card?
Its role is specific to the OS 525/CS 275 N-AT local-bus path. A general serial application needs an interface intended for that protocol and system.
Where should troubleshooting start when 6DS1222-8BA does not restore local-bus communication?
Trace the OS 525-to-CS 275 path first, then compare the programmed-device labels and switch positions with the working system baseline before replacing hardware.
