H8575-E

 

 
Description: 25 pin D-Sub male (DB25) to MMJ, EOS/ESD, Screws, Straight wired  Use: (DTE) Connect 25 pin EIA232 female ports on printers to other DTE devices using MMJ cabling. Provides the required crossed connection when used with the BC16E or BN24H cable.

H8585-AC

 

Description: 25 pin D-Sub male (DB25) to MJ8, EOS/ESD, Screws, Straight wired Use: (DCE) Connect 25 pin EIA232 male ports on modems to MJ8 serial ports on DECserver Access Servers. Provides the required straight through connection when used with the BN25G cable. Suggested for line speeds greater than or equal to 9600 bps. Note: Not for connection to public networks in Sweden, Germany or Japan.

H8585-AB

 

 Description: 25 pin D-Sub male (DB25) to MJ8, EOS/ESD, Screws, Straight wired  Use: (DCE) Connect 25 pin EIA232 male ports on modems to MJ8 serial ports on DECserver Access Servers. Provides the required straight through connection when used with the BN25G cable. Suggested for line speeds less than 9600 bps. Note: Not for connection to public networks in Sweden, Germany or Japan.

H8575-D

 

 
Description: 25 pin D-Sub male (DB25) to MMJ, EOS/ESD, Screws, Crossover wired.  Use: (DCE) Connect 25 pin EIA232 female ports on modems to DTE devices using MMJ cabling. Provides the required straight through connection when used with the BC16E cable.

H8585-AA

 

 
 Description: 9 pin D-Sub female (DB9) to MJ8, EOS/ESD, Screws, Crossover wired.  Use: (DTE) Connect 9 pin EIA232 male ports on PCs to MJ8 serial ports on DECserver Access Servers or MJ8 set up ports on DEChub products. Provides the required crossed connection when used with the BN25G cable.

H8571-J

 

 

Corrected 2/6/98

 Description: 9 pin D-Sub female (DB9) to MMJ, Screws, Straight wired.  Use: Connect 9 pin EIA232 male ports on PCs to other DTE devices using MMJ cabling. Provides the required crossed connection when used with the BC16E or BN24H cable.

H8572-00 Cable Coupler

 

Description: Back to back MMJs, Crossover wired. Use: Joins two BC16E terminal/printer interconnect cables.

H8571-C Cable Adapter

 

 
 Description: 25 pin D-Sub male (DB25) to MMJ, EOS/ESD, Stand offs, Crossover wired. Use: Attaches existing EIA232 DB25(F) cable to adapt to MMJ cabling. Provides the required straight through connection when used with the BC16E or BN24H cable.

H8571-F Cable Adapter

 

 
 Description: 25 pin D-Sub male (DB25) to MMJ, Stand offs, Crossover wired.

This adapter was never sold, but was included with DIGITAL terminals and printers. This is a reduced cost equivalent to the H8571-C.

Use: Attaches existing EIA232 DB25(F) cable to adapt to MMJ cabling. Provides the required straight through connection when used with the BC16E or BN24H cable.
