Serial Connector
The serial connector for all CR Series Compact Routers (including the CR6400 family routers) has
this pinout:
The connector is RS-485 and can be used as RS-422. It communicates at 38,400 Baud rate (no
parity, 8 data bits and one stop bit).
All compact routers also support RS-485 multi-drop.
Compact routers communicate using a subset of NVSP (NVISION serial protocol). They accept
any command and respond to the following commands:
0x01 Device Present
0x15 Extended Software Version Command
0x50 Take (without timestamp)
0x51 Destination Status
0x55 Lock Destination
0x58 Release Destination
0x59 Level Configuration
0x5D Tally
0x5E Salvo (without timestamp)
0x66 Destination LPR State
0x67 Machine Control Salvo Command
0x68 Expanded Tally Command
0x80 Error Response
0x81 Error Response to Sequenced Message
Customers who want to operate the router through its serial port using an automation system
or an external control system may contact Grass Valley technical support for information and to
obtain the NVSP protocol document (which is essential).
The serial port of remote panel modules is presently non-functional.
