Optional Items 
Depending upon your application, you are likely to find one or more of the following 
items useful for interfacing the ACB-ULTRA.LPCI to real-world signals. All items 
can be purchased from our website (http://www.sealevel.com
) or by calling 864-843-
4343. 
  CA-178 – A 6’ shielded cable with a DB-25F connector to an ITU-T ISO-2593 
style connector (V.35), and converts the Sealevel DB-25 implementation to the 
ITU-T V.35 mechanical standard. 
  CA-104 – A 6’ extension cable with one DB-25M connector and one DB-
25Fconnector, pinned one-to-one, for use with RS-232 and RS-530. 
  CA-107 – A 10” shielded cabling adapter with a DB-25F (RS-530) to a DB-37M 
(RS-449 DTE). RS-530 is replacing RS-449 in Telecom applications, but there is 
still a very large installed base of equipment that still uses the RS-449 pin-out. 
Both standards use RS-422 to define the electrical specifications and are 
interchangeable via this adapter cable. 
  CA-159 – A 6’ shielded cable with a DB-25F (RS-530) to a DB-15M (X.21), and 
converts the standard DB-25 implementation of RS-530 or RS-422 to the ITU-T 
X.21 standard.
