TM-350/400 Operating Manual
4.2.2 IEEE-488 Option Board (optional)
The optional IEEE-488 interface provides the TM-350/400 with the ability to
communicate with computers and other devices over a standard IEEE-488
interface bus.
Figure 3-6 on page 3-9 shows the connector and Table 3-3 on page
3-9 shows the signal assignments.
4.2.3 Digital To Analog Converter (DAC) Connection
The Digital-to-Analog Converters are interfaced via a 7-pin, circular mini DIN
connector. The mating connector is a CINCH MDX-7PI or equivalent.
Figure 3-8 on
page 3-11 shows the DAC connector and Table 3-5 on page 3-11 shows the signal
assignments.
4.2.4 Remote TTL Inputs
A short across the input pins activates TTL level inputs. The pins must be shorted
for a minimum of 200 ms or else the monitor will consider it unintentional and ignore
it. Provides for remote activation of the Start, Stop, Film Number, Increase and
Decrease function keys.
Figure 3-5 on page 3-8 shows the connector and Table
3-2 on page 3-8 shows the signal assignments.
4.2.5 Relay Outputs
The Source Shutter output is an isolated, SPST, normally open relay, rated at 120
VA, and 2A max. The Sensor Shutter (TM-400 only) output is an isolated, SPST,
normally open relay, rated at 120 VA and 2A max
Figure 3-4 on page 3-7 shows
the connector and Table 3-1 on page 3-7 shows the signal assignments.
4.2.6 Line Voltage Selection and Fuse Replacement
The TM-350/400 is compatible with AC line voltages of 100 through 120 or 220
through 240 V(ac) at 50 to 60 Hz. The two line fuses are IEC T Type (Slow),
4/10 A, 250 V(ac). To select the line voltage or to replace the fuses, see
Figure 4-1
on page 4-3 and follow the steps below.
