3.1. Communication Parameters


The Setup Switches, located on the underside of the unit, select default settings for all RS-232 ports. Setup Switch functions are summarized in Section 4.1 and on a label on the bottom of the unit.

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).

For the purpose of this overview, use the default Setup Switch configuration. Set your communications program (e.g. ProComm) to use the following parameters:

•                      9600 Baud

•                      RTS/CTS Handshaking

•                      Full Duplex

•                      8 Bits, No Parity, 1 Stop Bit


Using Other Parameters (Optional): If desired, the APS-16 can be set to match the parameters used by the communications program. Refer to Section 4.1 and configure Setup Switches accordingly. After changing the Set-Up Switches, initialize the APS-16 as described in Section 4.2.


•                      Section 4.1 describes procedures for setting the APS-16 to match the parameters used by your communications program.

•                      If Setup Switches are changed, the new configuration will not take effect until the unit is initialized.
