The DHD External Control Protocol can be used on TCP/IP or serial interface to control the DHD devices from external systems.
The following table shows the availability of these interfaces dependent on the various frame/controller types:
| Protocol Interface | ||||
|---|---|---|---|---|
| Frame Type | Controller Type | RS232 | RS422 | TCP |
| RM4200D DSP Frame | RM420-850 | 1 port on RM420-850 controller + 1 to 3 ports on each RM420-851 DSP Controller (max. 4 ports) | - | max. 10 sockets1 |
