SC-ION: Serial Control I/O Board Quick Reference

One or more SC-ION boards may be used in an iCentral group controller. The SC-ION board
provides a communications interface between discrete signal level or relay-oriented field equip-
ment and the serial communications bus used by iCentral for serial hall call and other serial
messaging. Inputs and outputs on the SC-ION board are assigned unique serial addresses at the
factory according to customer requirements. Using iView, customers can view the function
assigned to each address and may even assign a different (MCE-supported) function if their
needs change. Each SC-ION board provides 16 user-configurable inputs and 16 user-configu-
rable outputs.

I/O Connections

Connect inputs and outputs as shown in your job prints. SC-ION board inputs are always
117VAC. Outputs may be configured (in specific groups) to provide either a path to ground or
current to drive indicator lamps/LEDs.
Output State Selection
a common. The common may be wired to provide a current source or a path to ground. The
groups are:
• Relays 1 — 4
• Relays 5 — 8
• Relays 9 — 16
The commons for the groups are determined by the connections made to board connector J4.
The appropriate connections are determined during the job survey. Each system is configured
before shipment. You need only connect the inputs and outputs as shown on the job prints.
Board Addresses
the system bus. The addresses are assigned as indicated by the job survey before the system is
shipped. A software tool, running on a Windows platform, is used to set individual addresses
and also to set the address range (10-489 or 10-989) used for the job. To configure the board, a
Windows PC running the software tool must be connected to the board serial port.
