The DZ11 was a UNIBUS 8 port asynchronous serial line mux card for DEC computers.
It was a hex card, which plugged into an SPC backplane slot, and used programmed I/O. The EIA version was the M7819, and the 20mA was the M7814. The EIA model can operate with modems.
On the M7819, a flat cable led from a Berg connector on the card via a static fiter to an EIA distribution panel holding 16 DB25 connectors, enough for two DZ11 cards.
Accessories for the EIA version are:
- BC05W-5 50 conductor signal cable
- H7004C Static Filter
- BC06L-0J 50 conductor signal cable
- H317-E EIA distribution panel
- Cable Box assembly
- H325 test connector (single line)
- H3271 staggered test connector
For the 20mA, substitute the:
- BC08S-15 40 conductor signal cable
- H7004B Static Filter
- BC06K-0J 40 conductor signal cable
- H317-F 20mA distribution panel
- H3190 staggered test connector.
Also, the later H3006 distribution panel for the EIA version was part of DEC's modular back-panel system.
