WEIGHT (Typical):
3200-1E & 3200-2E: 117 g (4.1 oz)
3201-1E: 89 g (3.1 oz)
3205-1E, 3205-2E, 3205-3E: 77 g (2.7 oz)
3206-1E: 99 g (3.5 oz)
3209-1E: 159 g (5.6 oz)
CONTROL CONFIGURATION:
Standard Unit: One terminal is connected to case ground
and the remaining terminals are provided for activation of
individual cells. Attenuation is fail-safe to "0" setting in the
absence of a control voltage. Application of a voltage (+) to
a particular cell causes it to switch to the attenuate position.
Units with TTL Option: Units with this option are supplied
with a very low profile connectorized TTL interface board
mounted directly to the control terminals. This TTL interface
option is available with either a 10 pin ribbon cable connec-
tor or a 15 pin "D" connector (limited models), refer to list
below. Each type is supplied with a mating connector. Refer
to Physical Dimensions for mating connector pin/wiring
details. Two wires are specified for supply voltage and
ground. The remaining wires will accept TTL control signals
to activate or de-activate a particular attenuation cell. A TTL
high will energize a cell to the high attenuation state,
whereas a TTL low will maintain a cell in its zero attenuation
state.
To order 3200 Series Attenuators with this option add -1 to
basic model number for ribbon cable connector and -2 for
the "D" connector. Example: Model 3201-1E with a TTL
interface board would be 3201-1E-1. Mating connector is
provided. To order a TTL Driver board separately for an
existing 3200 Series Attenuator, use the following:

** 3 FT TTL Interface Cable Part No. 101-1805 supplied with unit.
Note: Control is non-latching and requires a continuous
control signal for the period of time in which attenuation is
required.
INTERFACE CONNECTOR: Option -1(Models 3200, 3201,
3205 and 3206): 10 pin .025 square post header on .1
center, mates with Amp connector 746285-1 or equivalent.
Option -1 (3209): 14 pin .025 square post header on .1
center, mates with Amp connector 746285-2 or equivalent.
Option -2: 15 pin D Socket Connector, mates with Cannon
connector DA-15S or equivalent.
