RCO - Remote Control Output

Examples of RCO usage

The Remote Control Output RCO’s are used to operate relays for control of external equipment.

Relay outputs are typically used for:

• Door opening
• PA control
• Call indication
• Queue indication
• Keying of mobile radio transmitter
• CCTV interface

Devices supporting RCO’s

• RCO outputs are available on a number of devices:

Device	# of RCO's	Comment	Hardware required
AlphaCom XE26	138	6 RCOs per ASLT card or ATLB-12 card	MRBD relay board + PDB Power Distribution Board
AlphaCom XE20	102	6 RCOs per ASLT card or ATLB-12 card	MRBD relay board
AlphaCom XE7	12	Need ASLT in position 1 and/or 2	MRBD relay board
AlphaCom XE1	0	RCOs not available. Use IPARIO unit	IPARIO unit
IPARIO unit (IP)	8	Remote outputs over IP network	IPARIO unit
RIO unit (analog)	18	Remote outputs over RS232/485	MRBD relay board
IP Substation board (PCB 8022)	2	One relay on connector P3, pin 3/4	The second output is a logical signal. Transistor + relay required
IP Flush Master/IP OR station (PCB 8024)	2	One relay on connector P3, pin 3/4	The second output is a logical signal. Transistor + relay required
Turbine Compact/TKIS-2 kit	7	One relay included	Use MRBD relay board if more than 1 relay is needed

Configuration

There are several commands available to operate RCOs, the most commonly used one is the RCO command

Logical RCOs

• The RCO command operates a logical RCO
• Each logical RCO must be mapped to a Device or Station, and to a Pin Number
• The AlphaCom XE software supports up to 500 logical RCOs.
• The operation of the logical RCO is configured from AlphaPro, in the Event Handler window.

Mapping of RCO's

There are 500 logical RCOs. In AlphaPro there is a RCO mapping table where the logical RCO is assigned to a physical address. The physical address is given as device + pin-number or by station + pin number. The RCO command is used in the Event Handler to program the behavior of the RCO's defined in the RCO table.

The outputs can be used freely within the whole exchange, regardless of physical connections of the stations.

The exchange always keeps track of the state of an output in case the device becomes faulty. When a faulty device becomes OK again, the exchange will restore the RCOs.

Additional Information

• For internal RCOs (ASLT/ATLB), the device address is 65, and the pin number is the same as the Physical number of stations, 1 - 552.
• When the ATLB board is used in AlphaCom E7 only four RCO's are available
• Mappings for the internal RCOs in the master are autoloaded. Mappings for RCOs in slave modules, RIO units and IP stations must be manually programmed.
• In an AlphaNet installation you can control RCOs in a remote exchange.

Software

• AMC 10.50 or later to control RCOs in slave modules. Earlier AMC versions support RCOs in master module only (pin 1 - 138).
• AMC 10.04: Additional parameter to pulse the RCO ('RCO 12 ON 20' to generate a 2.0 sec pulse on RCO 12)
• AMC 07.40 or later to control RCOs in an AlphaNet installation.
