What Digi RF family was the XTH9-PKI-R-NA ?

Hi team, My customer is requires replacements for the Digi XTH9-PKI-R-NA now EOL. They will be purchasing Digi Xtend however he needs to confirm that the DB9 female serial port pin outs are the same. IF they aren’t could you please what the old XTH9-PKI-R-NA is so we can compare this to the Xtend ?
Note: we tried to locate any form of documentation for these old XTH9-PKI-R-NA but have been able to locate a datasheet, owner’s manual, quick start guide, etc. A link will be appreciated.
Could you also advise what this old unit Digi family so we can identify the product.
Thanks for your help and all the best.

That was the old 9xtend product which has been discontinued. The Replacement is the XTP9B product line.
