CHAPTER 3: Installation and Configuration
• Follow these steps to configure your
SFOM-HS2 for for asynchronous operation.
a. Use switches 1, 2, and 3 to select “async”
(turn XMT timing off).
b. Use switch 4 to set the data rate.
c. Use switches 5, 6, and 7 to set frequency
allowance and character length (if necessary,
refer to
Table 3-1
on
page 17
,
Figure 3-1
on
page 15
).
d. Use switch 8 to set carrier to constantly
on or controlled by RTS.
For example, DIP-switch settings on an SFOM-
HS2 configured for async operation, 64 Kbps,
and constant carrier would be:
1, 3 = OFF
2 = ON
4 = ON
6, 7 = OFF
8 = ON
NOTE
PCs working at high speeds in async mode operate at
57.6 Kbps (instead of 56 Kbps). In such cases, the PC
should be set to use two stop bits, and the SFOM-HS2
should be set to use one stop bit and to communicate
at 56 Kbps.
