Product Overview
What the ML 12 CCS delivers
The Contact Closure to RS232 Convertor model ML 12 CCS is a purpose engineered hardware interface device designed to bridge physical dry contact terminal states with standard serial network control architectures. The system translates physical closing loops into precise digital hexadecimal and decimal code messages output directly through a rear panel interface.
The system utilizes 4 pin captive screw connection modules where each terminal block handles 2 standalone input channels. Terminal mapping points match standard numbering schemes where point 1 and common point C serve channel 1, and point 2 and common point C serve channel 2, repeating uniformly across all 12 supported contact channels.
Advanced system adjustment mechanisms are handled directly via a layout of structural DIP switches on the enclosure. By altering the position combination of DIP switch numbers 1, 2, 3, and 4, operators can adjust the trailing ASCII code validation character emitted with each message string, switching between standard communication marks like exclamation marks, hashes, and question marks.
To enable multi layered operation parameters, the ML 12 CCS integrates a dedicated physical toggle switch component at the rear terminal section. When active, this switch grants single contact points dual control functions, alternating the emitted data between distinct primary decimal and secondary double contact hex string blocks upon consecutive physical activations.

Installation
Contact terminal setup and serial deployment
The ML 12 CCS supports clean structural installation, establishing secure physical contact monitoring paths and standardized outbound serial parameters over integrated connection interfaces.
01
Terminal Block Wire Routing
Incoming mechanical sensors or switches are connected directly to the 6 integrated 4 pin captive screw modules. Each connector pair shares a joint common grounding terminal, marked clearly as C. Pin point 1 and point C complete the transmission loop for the first channel within the block, while pin point 2 and point C satisfy the secondary channel wire route. All 12 channels wire sequentially using this terminal strategy.
02
Serial Interface Parameter Configuration
The outbound data route runs through a single D9 female connector fixed on the rear interface panel. To achieve safe data parsing with connected host computers, terminal control systems, or automation controllers, the listening serial port must match specific hardware properties. Communication parameters are fixed explicitly at 9600 baud rate speed, using 8-bit data width, 1 stop bit architecture, and no parity checking loops.
Where the ML 12 CCS performs
Designed for automated integration networks requiring robust bridging between hardware relay switches and centralized computational tracking machinery.
Industrial Relay Status Monitoring
Links factory mechanical breaker points or power relay terminals directly to localized data terminal machines, feeding switch position logs instantly through structured decimal code messages.
Central Control Room Automation

FAQs about the Contact Closure to RS232 Convertor ML 12CCS
What is the Contact Closure to RS232 Convertor ML 12 CCS used for?
The Contact Closure to RS232 Convertor model ML 12 CCS by Milestone is an industrial purpose hardware tool developed specifically to help users convert incoming dry contact closure loops into digital RS 232 interface serial data strings for automated system management.
How far can this HDMI extender transmit signals?
This hardware does not employ data extension cabling parameters. It accepts physical wire connections from up to 12 distinct dry contact zones directly onto its localized 4 pin captive screw block connectors and pipes data over a standard serial path via its rear D9 connector port.
Will the video quality remain clear over long distances?
The ML 12 CCS convertor is a dedicated digital serial character tracking device, not a video transmission unit. It focuses purely on processing contact terminal loop activations into clean decimal and hexadecimal control strings without managing video signals.
Can I control my source device from another room?
Control transmission is managed by routing physical lines into the captive screw terminals. When an external contact point closes, the convertor automatically creates and pushes serial text bytes directly to a paired master tracking terminal or local host computer.
Where is the HDMI IR Extender commonly used?
This multi channel contact closure terminal unit is widely integrated within automated operations control rooms, legacy status monitoring setups, electrical relay signal diagnostic frameworks, and general industrial plant connectivity systems requiring physical wire state tracking.
Can one transmitter send the signal to multiple displays at the same time?
The unit uses a point to point serial tracking methodology. Outbound command strings are transmitted exclusively through a single rear panel D9 female port connector that feeds data down a dedicated point to point wire path directly into one receiving serial terminal socket.
Does this extender require any specialist cabling?
No specialized networking cables are required. Contact wiring attaches simply using bare wiring loops straight inside the captive screw terminal slots, while the system output line connects using standard D9 connector cabling configured to link with pin 3 and pin 5 serial paths.
How does the rear panel toggle switcher affect the contact channel behavior?
When the physical rear toggle switch is set to ON, single input contact channels switch to dual function execution mode. Operating the contact line for the first initial instance pushes single contact string codes like 1!, while activating it a second consecutive time emits separate double contact data like A!.
What are the necessary communication interface settings for the listening serial device?
The host processing terminal must match the static internal configuration of the convertor exactly. Operational connection parameters require a fixed 9600 baud rate speed configuration, an 8-bit data character width structure, exactly 1 stop bit length termination, and no active parity checking loops.
