Serial Control using AMX NetLinx® Controller
Product Application Notes |
| Control a VEEMUX Audio/Video Matrix Switch using an AMX NI-2100 NetLinx® Controller with a terminal emulator such as HyperTerminal. Use a Null Modem cable to connect the PC COM port to the AMX Program port. For connecting the AMX RS-232 port to the VEEMUX, use a straight thru, DB-9 Male to DB-9 Female cable. For some NTI products, a DB-9 to RJ-45 adapter may be required, refer to the product's User Manual for more information. Terminal Session:
Type echo on <Enter> to view the characters while entering commands. You should see a ">" command prompt in the terminal window. Configuring the AMX RS-232 Port: The baud rate of the AMX RS-232 port that is connected to the VEEMUX must be set to match the baud rate of the VEEMUX. In the terminal window, type: SEND_COMMAND 5001:1:1,'SET BAUD 9600,N,8,1'<Enter> Assumes factory default configuration and AMX RS-232 port 1. Testing the connection: In the terminal window, type: PASS 5001:1:1<Enter> The unit responds with "Entering pass mode." In the terminal window, type: ++<Esc>A The unit responds with "-- Ascii mode --" You should now be able to enter VEEMUX commands: In the terminal window, type: RU 01<Enter> The unit responds with "*<CR>IP,OP<CR>" Where IP is the number of Input Ports and OP is the number of Output Ports on the attached VEEMUX. Using the AMX SEND_STRING Command: The AMX SEND_STRING command can be used to send a string of characters to the VEEMUX. The string can be any valid VEEMUX command. The AMX controller must not be in Pass Through mode. To exit Pass Through mode: In the terminal window, type: ++<Esc><Esc> The unit responds with "Exiting pass mode." Example: To connect Input 1 to Output 3 on VEEMUX Unit 1. In the terminal window, type: SEND_STRING 5001:1:1,"'CS 01,01,03',13" The VEEMUX should make the connection Input 1 to Output 3, and should indicate on the LCD that the connection has been made. |
