Manuals/Vacuum Compatibility Notes
From ZaberWiki
Zaber's vacuum compatible devices are identical in appearance and function to their non-vacuum compatible counterparts with only a few exceptions as noted below.

[edit] Lubrication
All lubricated interfaces (motor bearings, leadscrews, leadnuts, etc) are greased using a silicon based vacuum compatible lubricating gel (NyeTorr 5300, vapor pressure ~5x10-9 Torr at 25°C). Every effort is made to remove all traces of any original greases (some components arrive pre-greased by the manufacturer) but for best results, degassing is recommended before use in the final application.

[edit] Power
No power connectors are provided on vacuum compatible devices. Power must be supplied through the data cable lines.
[edit] Data cable extensions
Vacuum compatible devices use the same mini-din cable extensions as standard (non-vacuum compatible) devices, however, the cable jacket is stripped back to the connectors to expose the individual wires. The mini-din connectors are left attached to facilitate easy testing. After initial testing, the wires can be cut and spliced to a feed-through on the vacuum chamber. Communication lines can be wired back to the appropriate mini-din connector outside the vacuum chamber. Power lines can be wired to any appropriate power supply. See the table below for pinouts. If there are multiple devices inside the vacuum chamber they may be connected using the attached mini-din connectors, or for improved vacuum compatibility, the connectors may be removed and the communications and power wires may be permanently wired together. The following table shows the data cable pinouts:

| Pin# | Minidin 6 Female (to next device if there is one) | Minidin 6 Male (to previous device or computer) | Color Set 1 | Color Set 2 |
|---|---|---|---|---|
| 
| |||
| 1 | - | - | - | - |
| 2 | Receive (from next device) | Transmit (toward computer) | Red | Brown |
| 3 | Ground | Ground | Orange | Red |
| 4 | +12V Power | +12V Power | Yellow | Orange |
| 5 | - | - | - | - |
| 6 | Transmit (to next device) | Receive (from computer) | Black | Green |
| nc | Brown, Green | Black, Yellow |
Note that multiple color sets are shown in the table above because multiple cable suppliers have been used over the years, each implementing different color codes. Rather than relying on this table it is recommended that user's perform a continuity test to determine which wires are connected to which pins on their own device. User's who have determined the color codes for their own devices are welcome to add to them to the table above if they are not already present.
