APPENDIX

CABLE:MODEL 5025-550-x (Non-Shielded)
MODEL 5025-551-x (Shielded)

Type:  Flat Ribbon Cable, 50-wires (female connectors at both

ends)The ‘-x’ suffix designates the length in feet (12 feet
maximum)Choose shielded or unshielded cable according to
model number.  The unshielded cable is recommended for
digital I/O, while the shielded cable is recommended for
optimum performance with precision analog I/O applications

Application:  Used to connect a Model 5025-552 termination

panel to the AVME9630/9660 non-intelligent carrier board A-
D connectors (both have 50-pin connectors)

Length:  Last field of part number designates length in feet (user-

specified, 12 feet maximum)It is recommended that this
length be kept to a minimum to reduce noise and power loss

Cable:50-wire flat ribbon cable, 28 gage.  Non-Shielded cable

model uses Acromag Part 2002-211 (3M Type C3365/50 or
equivalent)Shielded cable model uses Acromag Part 2002-
261 (3M Type 3476/50 or equivalent)

Headers (Both Ends):50-pin female header with strain relief

.

Header - Acromag Part 1004-512 (3M Type 3425-6600 or
equivalent)

Strain Relief - Acromag Part 1004-534 (3M Type

3448-3050 or equivalent)

Keying:  Headers at both ends have polarizing key to prevent

improper installation

Schematic and Physical Attributes:  For Non-Shielded cable

model, see Drawing 4501-462For Shielded cable model, see
Drawing 4501-463

Shipping Weight:10 pound (05Kg) packaged

CABLE:MODEL 5029-944

Type: Model 5029-944 IP503 Communication Cable:  A five foot

long, flat 50-pin cable with a female connector on one end
(for connection to AVME9630/9660 or other compatible
carrier boards) and two DE-9P connectors (serial ports) plus
one DB-25S connector (parallel port) on the other end

ApplicatIon:  Used to connect to two DB-9 serial ports and 1

Centronics parallel port to AVME9630/9660 non-intelligent
carrier board A-D connectors.  It is recommended for use
with Acromag Model IP503 serial communication modules

Length:5 feet
Cable: 50-wire flat ribbon cable, 28 gage.  Non-Shielded cable

model uses Acromag Part 2002-211 (3M Type C3365/50 or
equivalent)

Headers:50-pin female header with strain relief

.  Header -

Acromag Part 1004-512 (3M Type 3425-6600 or
equivalent)

Strain Relief - Acromag Part 1004-534 (3M Type

3448-3050 or equivalent)

Serial Port Connectors:  Four DE-9P (9-pin, D-SUB, Male)

connectors with strain relief (3M connector U89809-9000 with
3448-8D09A strain relief, or equivalent)

Parallel Port Connector:  One DB-25S (25-pin, D-SUB, Female)

connector (3M connector U89925-9000 with 3448-8D25A
strain relief, or equivalent)

Keying:50-pin Header at one end has polarizing key to prevent

improper installation
