1 DESCRIPTION
The one-wide CAMAC 182 module provides basic digital
output control facilities. Thirty-two individual control
lines are provided. These lines are active high, TTL
compatible outputs sourced from 74128 gates. They are
capable of driving low impedance lines and may easily be
opto-coupled.
The control lines are addressable as two separate 16 bit
words for monitor and control. The setting of one or more
output bits within one or the other control words is a two
step process. The first part of the process is the writing
of a 16 bit clock enable mask which defines the control bits
that may be altered. The data contained in the second
operation of writing the control word effect only those bits
selected by the previous mask. The read/modify/write
operation is thereby avoided. The two step setting process
easily accommodates bit, selected bits, nibble, and byte
control in applications where separate devices or parameters
are controlled from a single module.
Upon clear command or powering-up, all control lines are
set to the off state - logic low. The clock enable masks
are also set off.
Please note that the labeling of control bit outputs in
this document is different from what was originally
published in the hand written description of the CAMAC 182
module. The labeling was changed so as to better conform to
accepted annotation conventions.

the control outputs and clock enable
masks to zero.

4 CAMAC 182 MODULE - FRONT PANEL
The CAMAC 182 module has only a N led (Red, stretched) on
the front panel to indicate addressing from the CAMAC
dataway.
5 SPARES
A supply of CAMAC 182 operational spares is maintained on
the second floor of the Linac Annex.
