Connect third-party serial modules

Third-party Ethernet-to-serial modules add serial communication ports to connect additional external
devices such as XMVs and transmitters. For instructions about using MOXA
modules used to expand serial capacity to the controller, see section
MOXA® modules.

Power the RMC

This section describes two modes for powering the controller. Select one mode:
–
Battery mode: a 12 volt battery with a charger supplies power (see section 3.7.2).
–
External power mode: an external power source supplies power (see section 3.7.3).
Follow the instructions for the appropriate power mode, then continue to section 3.8,
battery backup.
NOTICE – Equipment damage. The maximum input voltage for legacy TFIO modules is 12
Vdc.
IMPORTANT NOTE: Externally fuse the power input for the load. This consists of the equipment,
plus any external devices powered by the RMC. The wire gauge should be appropriate (in some
applications a minimum of 16 AWG gauge is advisable).

–
ABB TOTALFLOW RMC-100 identifies the controller name and model
–
BOOT 2105412-XXX indicates the version of the boot software
–
OS 2105411-XXX indicates the version of the operating system
–
Super CAP Charged indicates if the super capacitor is charged (see section 2.2.9)
–
