Accessories
Accessory 1: +5V Power Supplies and Batteries
These power supplies are needed only for stand-alone applications of the PMAC, when the cards are not
getting their +5V supply from the bus. The version of this accessory is selected by capacity:
Acc-1: for one PMAC (3.0A rating).
Acc-1A: for two or three PMACs (6.0A rating).
Acc-1B: for four or five PMACs (9.0A rating).
Acc-1C: for six, seven, or eight PMACs (12.0A rating).
Acc-1L: is a replacement battery for the RAM on older PMAC PC or PMAC VME CPU boards.
It is a 3V lithium battery, 1200 mAh, 2/3A-size, no tabs.
Acc-1LS: is a replacement battery for the RAM on PMAC STD, PMAC Lite and newer PMAC
PC and PMAC VME boards. It is a 3.6V lithium battery, 1000 mAh, 1.15" diameter
can.
Acc-1SA: 5V-switching power supply for one PMAC (1.2A rating). Gives better transient
suppression.
Accessory 2: +/-15V Power Supplies
These power supplies provide +/- 15V to the analog output stage of PMAC, which is optically isolated
from the digital 5V circuitry. This accessory has the following versions:
Acc-2: +/-15V only for one PMAC (1.5A rating at each level).
Acc-2A: +/-15V, +5V for one PMAC (16W rating).
Acc-2B: +/-15V, +5V for two PMACs (40W rating).
Acc-2SA: 12V-switching power supply for one PMAC (1.2A rating). Gives better transient
suppression.
Accessory 3: Serial Communications Cable
This is a three-meter (ten-foot) 26-strand flat cable with a DB-25 connector on one end (for connection to
the host computer) and an IDC 26-pin connector on the other end (for connection to PMAC’s serial port).
It is not to be purchased if Acc-26 serial-communications-converter card is purchased. Multi-drop
versions of the cable are available for daisy-chained PMAC systems:
Acc-3D: Single-drop 3-meter DB-25 to IDC-26 flat cable (PC/VME).
Acc-3E: One additional PMAC drop on Acc-3D.
Acc-3L: Single-drop 3-meter DB-9 to IDC-10 flat cable (Lite).
Acc-3S: Single-drop 3-meter DB-25 to SIP-5 cable (STD).
Accessory 4: Additional Instruction Manual
This accessory provides an additional instruction manual for the PMAC. Normally, one manual is
provided with every four PMACs or fraction thereof shipped together.
