Accessory 20: Hand-Held Terminal
This accessory provides a TM200G-001 hand-held or panel-mountable (~5" x 8" x 3/4") terminal for
simple operational communications needs. The terminal communicates with the serial port on the
PMAC. It provides a numeric keypad with 6 special programmable function keys; also an alphanumeric
2 x 24 LCD display. Comes with a 24" 26-pin cable.
Accessory 21: I/O Simulators and Cables
Acc-21 is a family of I/O simulators and cables for connection to the J5 (JOPT) connector on PMAC.
Many users will purchase OPTO-22 boards and connect it to PMAC with an Acc-21 cable from Delta Tau.
Acc-21F: 180 cm (6') 50-pin card edge to 34-pin IDC header cable, for connecting PMAC JOPTO
connector to PB8/16/24 or equivalent boards.
Acc-21FH: 180 cm (6') 50-pin IDC header to 34-pin IDC header cable, for connecting PMAC
JOPTO connector to PB8/16/24H or equivalent boards.
Acc-21G: 180 cm (6') 50-pin card edge to 50-pin IDC header cable, for connecting Acc-14D/V and
Acc-34B to PB8/16/24 or equivalent boards.
Acc-21GH: 180 cm (6') 50-pin IDC header to 50-pin IDC header cable, for connecting Acc-14D/V
and Acc-34B to PB8/16/24H or equivalent boards.
Acc-21S: I/O simulator for PMAC JOPT port with eight switch inputs and eight LED outputs.
Comes with 1m (40") 34-pin cable.
Accessory 22: Extended Warranty
This accessory extends the warranty past the one year standard factory warranty, for a total of two years
from the date of purchase.
Accessory 24: Axis Expansion Board
The Acc-24 Axis Expansion board (Acc-24P is for the PMAC PC; Acc-24V is for the PMAC VME; there
is no Acc-24 for the PMAC STD) provides four or eight additional channels each of quadrature encoders,
analog outputs, and data lines from analog inputs (for a total of 12 or 16 each for the PMAC). This
accessory is for those systems that require more than the eight channels of each that can be provided on
the baseboard. This would include systems with more than four PMAC-commutated motors, or with
more than eight quadrature encoders and handwheels. The board fits in the next open bus slot, and
communicates to PMAC via a provided 50-pin flat cable.
Acc-24P: Four-Channel Expansion Board for the PC bus. Comes with two 8 cm (3") cables, one
50-pin and one 10-pin.
Acc-24V: Four-Channel Expansion Board for the VME bus. Comes with two 8 cm (3") cables, one
50-pin and one 10-pin.
OPT-1: Additional four channels on the board (eight total).
OPT-2: 20 cm (8") 50-pin 3-drop connector cable. When Acc-24 is used with PMAC OPT-2,
Acc-14D/V, or Acc-36P.
