OPTION SWITCHES ON
THE DATA STAND
Before connecting the data stand to the MERLIN 11 system, you need to set
the switches on the bottom of the data stand to match those of the associated
data terminal. See Figure 3-2 for an example. The shaded portion of the
switch shows the switch setting.
FIGURE 3-2 Option switch settings on the 7406 data stand.
Follow these steps to set data option switches:
1 Set the parity switch (switch 1) for even or odd parity to match the data
terminal. (See the table below.) If the data terminal has no parity, the
position of the switch doesn't matter.
Set the speed switches (switches 2, 3, and 4) as shown in the table below.

The speed should match the speed of the data terminal.
