When S2 is switched off it will provide a contact outputs (dry outputs) for channels 1
and 2. When S2 is switched on it will provide voltage outputs (wet outputs) for
channels 1 and 2. S3 has the same functionality, but for channels 3 and 4. S2 and
S3 are normally both on or both off.
The first four input mapping switches (1-4) for S4 are used to select a channel
group. A channel group indicates which input channels are mapped to the cards
output channels. If the first four input mapping switches are all off then the channel
group is software configurable. Otherwise, the pattern of these switches selects the
channel group (see Figure D.3). The same on/off pattern used for these dip
switches is also used when doing software selection of the channel groups using the
faceplate mode switch (Compare Figure D.3 to Figure D.6). This allows selection of
channels as high as channel 28. Contact Wavetronix technical support if you have
questions on how to select channel groups.

The first three baud rate switches (1-3) for S5 are used to select the baud rate for
Bus 1. If the first three baud rate switches are all off then the Bus 1 baud rate is
software configurable. Otherwise, the pattern of these switches selects the Bus 1
baud rate.
Note
A switch is also off if it is not loaded onto the card. For example, S2 and S3
are not typically loaded because the rack card normally provides contact
outputs. These switches are only present in cases where the rack card needs
to output a voltage (wet) instead of a contact (dry). Please contact Wavetronix
customer support, if you have an application that requires a voltage output.
The voltage will normally be near VCC (typically 12 or 24 V). Then when the
contact closes, the output voltage will be near 0 V.
