4.1. Configure Setup Switches


When the APS-16 is shipped from the factory, the Setup Switches are configured for 9600 baud, 8 Bits-No Parity, RTS/CTS handshaking, verbose command response, and no echo (all switches ON). These switch settings are compatible with most applications. If the default settings are not compatible with your application, change the switch settings as described in the following subsections.

Setup Switches should be configured to match the parameters used by the device attached to Port 1. This allows access to command functions if the unit is initialized to default parameters.


•                      Please refer to the label on the bottom of the APS-16 in order to determine On/Off positions.

•                      Communication parameters (baud rate, parity, etc.) can be selected for each port using the /P command as described in Section 5.3. The /P command can select different parameters for each APS-16 port.

•                      When the APS-16 is initialized, parameters will return to the settings specified by the Set-Up Switches.
