4.2. Configure Option Switches
When the CMS is shipped from the factory, the Option Switches are configured for 9600 baud,
8 Bits-No Parity, RTS/CTS handshaking, verbose command response, and command echo ON
(all switches Down). These settings are compatible with most applications. If the default
settings are not compatible with your application, change the switch settings as follows.
The Option Switches should be configured to match the parameters your control device will use
when communicating with the CMS. This will ensure access to command functions, even if the
unit is initialized to default parameters.
Notes:
•
If the Option Switch configuration is changed, new parameters will not take effect
until the unit is initialized as described in Section 4.3.
•
Operating parameters (baud rate, parity, etc.) can be selected for each port using
the /P command as described in Section 5.5. The /P command can select different
parameters for each CMS port.
•
When the CMS is initialized, parameters will return to settings specified by the
Option Switches.
4.2.1. Default Baud Rate (Sw1, Sw2, Sw3)
Option Switches one through three select the default baud rate for all CMS RS232 Ports. The
default baud rate must match the rate your control device will use when communicating with
the CMS. If the control device will communicate via modem, select a default baud rate that is
compatible with the modem.
