4.1.2. DC Powered Units
The DC terminal block features two bus inputs as shown in
Figure 4.1. This allows you to connect only one DC power
source, or connect two DC power sources, with the second source
functioning as a backup.
When connecting the CMS to your DC Power source, first
remove the protective cover from the terminal block, attach the
wires from the -48 VDC power source(s) to the screw terminals
(the common lines from the two power sources are both
connected to the "0" terminal), connect the ground line to the
labeled ground screw, and then replace the protective cover.
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.
·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 individually selected for each port using the /P
command as described in Section 5.5.
