GENERAL DESCRIPTION
The Model 3610 is a single-width CAMAC module containing six independent 24-bit counters. These counters
accept either NIM * or TTL input and can count from dc to 50 megahertz. The type of input is user-selectable
for each channel. The external inhibit can be selected to be either NIM or TTL. Each counter has an overflow
bit which is set on a carry from either Bit 16 or Bit 24 and generates a LAM, if enabled. The pattern of overflow
bits in a module can be read. Counters can be inhibited by Dataway Inhibit or by a front-panel signal. They
can be individually cleared by Dataway command or as a group by Dataway clear or a manual pushbutton.
The input is protected for a ±50 volt transient or ±4 volts dc.
When precise timing of sequenced events is required, the Model 3655 Timing module provides a time base
for the 3610 by asserting the Dataway Inhibit line for a programmable interval.
When the count in any counter reaches 2'* (or 2'® selected by a jumper), that counter rolls over and con
tinues to count, and a corresponding overflow LAM status bit is set. The six LAM status bits are OR'ed and
when enabled, produce a LAM request. The pattern of the six LAM status bits can be read to locate the
specific counter that overflowed.
*The nominal NIM signal is: -16 mA into 500 for a 1, and 0 mA for a 0.

Single Pin LEMO Connectors
0-5
These six LEMO connectors are the inputs to channels 0 through 5.
Channel 0 is accessed through subaddress A(0) for F(0), F(2), F(9)
and F(10) function codes. Similiarly, Channel 1 through Channel 5
will have subaddress A(l) through A(5)f respectively.
T Two single-pin LEMO connectors are provided to inhibit the counting
when a low-true logical 1 is applied. These two connectors are
bridged to provide for "Daisy Chaining" with other 3610 modules.
When this input is strained for NIM signals, the spare Inhibit
input on the last 3610 should have a 50 ohm termination. These
Inhibit inputs are independent of the Dataway Inhibit.
All of the above inputs can be independently strapped for either TTL or NIM
signals.

TUPnT SIGNAL DESCRIPTION
All TTL inputs are low-true and represent one Schottky TTL load.
NIM All NIM inputs are terminated in 50 ohms except for the Inhibit
which is high in^edance. A logical 1 occurs when the output that
is driving the input, sinks 16 mA, thus forcing the input to -0.8
volts (50 ohms X (-16mA)). A logical 0 is represented by the
output that is driving the input, not sinking any current. The
input threshold is approximately a -0.4 volts.
M(M3DLE STRAPS
Six straps, one for each channel, are provided for the user to select if the LAM
status is set on the overflow of either 16 or 24 bits. These straps are located
in the middle of the board with Channel 0 at the bottom of the column and
Channel 5 at the top. Each channel is selected independently of the others.
With the strap in location A, the LAM status will be set on the overflow of 24
bits, while location B is used for selecting 16 bit overflow.
Seven straps, one for each channel and the Inhibit line, are provided for the
selection of whether the input will accept TTL or NIM signals. These straps are
located at the front of the module by the front panel. Each channel is
individually selected. With the strap in the up position, the input will accept
TTL signals. With the strap in the down position, the input will accept NIM
signals.
One last strap, labeled INK, is located by chip CA and is used for enabling or
disabling the Dataway Inhibit signal. With the strap in the UP position,
location A, the Dataway Inhibit signal is enabled. Relocating the strap to
position B will disable the Dataway Inhibit. This strap has no affect on the
front panel Inhibit input.
Refer to Figure 1 for strap locations.
