5. Reinstall the Main PCB in the bottom half of
the case.
6. On the Output Unit PCB use Table 602-2 and S1
to select the desired BAUD rate, select position 0 on
the Function switch S2, and select the PTI Bus
Address using S3. When using the RS-232-C inter­
face, set the address switch S3 to address 1,6, 7, 8, or
9. When using the 2XXX A-522 Personality Card and
the 1120A IEEE-488 Translator, set the baud rate to
2400 and follow all procedures regarding the RS-232-
C interface.
7. Connect the Output Unit cables to the
connectors on the Main PCB.
8. Attach the Output Unit PCB to the spacers,
component side down, and the connector to the rear
panel access port.
9. Replace the PTI cover on the instrument and
reconnect the input power sources, if required, at
this time.
602-9. OUTPUT CONNECTIONS
602-10. All connections between the Output Unit
Option and external instruments are made using the rear
panel connectors previously described. The analog
output is from standard banana jacks. The digital output
female connector has a mating male connector
accompanying the option. This allows the customer to
custom make a cable between the thermometer output
option and the receiving device. Table 602-3, is the pin­
out data for the digital output connector.

NOTE
Standard RS232C signals are output on 25-
pins, the connector on the -002 Output Option
is 36-pins, therefore, the user must either
hardwire the connection between the -002
Output Option or order the Y2026B, Cable
