Frequently Asked Questions - CCR 2BLB Extron
How do I connect the CCR 2BLB to my control system?
Use a standard RS-232 cable (DB-9) to connect to the COM port of your control system. Configure baud rate to 9600, 8 data bits, no parity, 1 stop bit.
What is the maximum load for each relay?
Each relay can switch up to 2 A at 30 VAC/VDC. Do not exceed this rating to avoid damage.
Can I power the device through the RS-232 port?
No, the CCR 2BLB requires an external 12 VDC power supply (included). The RS-232 port is for data only.
How do I mount the CCR 2BLB in a rack?
Attach the provided rack ear kit to the sides and screw into standard 19-inch rack rails. The device occupies 1/3 rack width.
What does the LED indicator mean?
A steady green LED indicates power is on. The relay status LEDs (if present) show when each relay is activated.
How do I control the relays via RS-232?
Use Extron SIS commands. For example, '1*1!' to close relay 1, '1*0!' to open relay 1. Refer to the manual for full command set.
What is the default communication protocol?
The device uses Extron's proprietary SIS protocol over RS-232. It operates at 9600 baud, 8N1.
Can the relays be triggered by external voltage?
No, the relay coils are internally switched. Only control via RS-232 or front panel (if applicable).
Is the CCR 2BLB compatible with third-party control systems?
Yes, as long as the third-party system supports RS-232 serial control and can send ASCII commands compatible with SIS.
Where can I find the latest user manual?
Download the manual from Extron's official website under product support. The manual includes wiring diagrams and command reference.
