The Model 202 can be mounted inside the
,
, or
GCs and the
, or it can be mounted in
a separate box, ready for connection to other manufacturers' GC or HPLC detectors. The Model 202 data system consists
of
and a four channel, 24-bit high resolution A/D board.
When mounted in an SRI GC, the Model 202 controls the
and the
of the carrier gas electronic pressure controller (EPC). When mounted in the
the Model
202 controls the pump speed and gradient profile. The eight available TTL outputs are connected internally within the GC
or HPLC to control functions such as valve rotation, gas solenoid actuation, autosampler injection, etc.
When mounted in a separate box, the temperature, pressure, and gradient control outputs are available for use, but are
not connected to anything. The eight TTL outputs are wired to a bank of eight single-pole, dual-throw mechanical relays
with screw terminals for easy connection to any user device which operates from a contact closure. Two remote start
inputs allow run initiation from the user's GC or HPLC system.
The four channels of data can be randomly assigned to one of two time bases, which allows independent start and stop
times for two entirely separate instruments. Data can be acquired at rates of up to 50Hz with one channel active, 10Hz
for two channels, or 5Hz with all four channels activated and acquiring data. Windows computers with two available
serial ports can operate dual Model 202 systems, for a total of eight data channels and four time bases from a single
PC platform. For computers with USB ports only, we recommend the IOGear USB PDA/Serial Adaptor (about $40US),
which allows serial peripherals to interface with USB computers.
