Communication card TMB-252 and TMBFI-252 CAD-250 control board
CAD-250 analog console communication card
⭐ incorporating an Ethernet port, RS485 output for loop or panel network connection, 2 x RS485 for third-party integration, RS232 output for the machine in series , It incorporates an electrical isolation circuit between the nodes. Maximum distance between nodes up to 1,000 meters
The TMB-252 communication card has different output ports for the following functions:
- 1 x RS-232 for serial printer connection
- 1 x RS-485 for analog panel network (T-Network) (1)
- 2 x RS-485 for integration with third parties, via Modbus protocol
Analog exchange and repeater networks can be ring or network, with up to 32 nodes. Maximum distance between two buttons
-TMB-252: 1 km (VND)
- TMBFI-252: 1.5 km (multimode fiber)
Incorporating an electrical isolation circuit between the nodes, which allows amplification of the signal transmission of the network, can be achieved long distances in the first node of the network and the last node. For example, if we have a network of 5 nodes, the total maximum distance of the network will be 5 km. The network card model TMB-252 adds Modbus functionality to PBXs similar to the CAD-250 Series, allowing remote control of key functions of these devices. This card also allows serial printer connection. (1) T-Network is only compatible with TMB-252 and TMBFI-252 . cards
