CHAPTER 3: Card Setup
3.4 Clock Modes
The PCI Card uses a unique clocking option that allows
you to select from “divide by 4” and “divide by 1”
clocking modes. These modes are selected at switches
SW3 and SW4. (See Appendix E for switch locations.)
To select the Baud rates commonly associated with
COM: ports (that is, 2400, 4800, 9600, 19.2, …
115.2 kbps), set switch-position 2 to the On position
(silk-screen “D4”). To select the maximum data rate
(460.8 kbps) set switch-position 1 to the On position
(silk-screen “D1”).
