5.12.4 Ports Tab
Figure 5.5 Console and Port Replicator Port Settings
While you cannot configure the scanner, you can configure communications with a serial
decoded scanner using the options in this tab.
Use these settings to ensure that the communication ports on Omnii match the settings of the
serial devices to which they are connected. If the settings do not match exactly, the devices
may not function. Note that some devices can auto-detect serial port settings (such as baud
rate), and in this case Omnii will dictate the settings. Baud rates often have a direct impact
on performance—they should be set as high as possible while still ensuring reliable
communication.
5.12.4.1 Port Replicator Port A (COM5) and Port B (COM6)
Port Replicator Port A (COM5) and Port B (COM6) are standard RS-232 DE-9 DTE ports
on the Omnii port replicator module, available on some snap modules and cradle types.
Enabled
This parameter must be set to ON in order for Omnii to recognize the device connected to
the Port Replicator 9-pin (COM5).
Power (COM6 only) - TBD
Pin 9 on Omnii COM6 is reserved for 5V power out and is defaulted to OFF. This parameter
must be set to ON to enable power to a Snap Module or Vehicle cradle.
