Q: How to automate Crestron control via RS232

Applies the following product:

- 4x4 HDMI Matrix + Video-Wall Processor (part # CE-H24C11-S1)

Solution:

RS232 Protocol:

Baud Rate 9600 bps
Data bit: 8 bits
Parity: None
Stop Bit: 1 bit
Telnet Protocol
Port:23
Username: admin
Password 123

ASCII Command & telnet command [terminal command]
All command must Carrier Return (0x0d)

>>POFF    // Turn off all output and front pannel
  Echo. poff

>>PON    // Turn on matrix
  Echo. pon

>>VR + CR    // Version command
  VR
    Echo
    88V_01.02  (show version number 01.02)
   VM-DB1.00.01      (show DB board version)

44V_01.02  (show version number 01.02)
VM-DB1.00.01      (show DB board version)
>> P**I** + CR  Single Output Set
Example:
    P01I02 // input 1 to output2

Echo
   p01i02
>> P**I00+ CR //Close Output Set
Example:
    P01I00 // close to output1
   Echo
   p01i00

>> P**L + CR  open Output
Example:
    P01L // open output1 [orginal set to source 2]
   Echo
   p01i02

>> P**+ + CR increase source
Example:
    P01+ //  next source for output1 [orginal set to source 1]
   Echo
   p01i02  [source change to source 02]
>> P**- + CR deccrease source
Example:
    P01- //  next source for output1 [orginal set to source 1]
   Echo
   p01i08  [source change to source 08]

>>MAP+ CR        // show 8 output port mapping
    p01i02
p02i02
….
p08i02
 
>> FSET+ CR
   FSET

Software command[Hex mode]
len 0x4d 0x41 0x52 0x88 0x43 0x48 0xff cmd cm1 cm2 cm3 cm4 cm5 cm6 cm7 … cm* checksum
0x52 0x88 for 8x8 matrix
0x52 0x44 for 4x4 matrix
len is the length from len to checksum
cmd is command index
cm1 to cm* is  setting value
checksum = sum from len to cm*
example:
set output mapping
0x12 0x4d 0x41 0x52 0x88 0x43 0x48 0xff 0x02 0x01 0x01 0x01 0x01 0x01 0x01 0x01 0x01 0xe
Cmd = 2 for set port mapping
Port1 1 port 2 1 port3 1 port4 1 port5 1 port6 1 port7 1 port8 1  
Check sum 0x0e
Echo 0xaa 

4x4 example:
0x0f 0x4d 0x41 0x52 0x44 0x43 0x48 0xff 0x02 0x01 0x01 0x01 0x01 0xc3
Cmd = 2 for set port mapping
Set Port1 1 port 2 1 port3 1 port4 1
Echo: 0xaa

2.>
Cmd =1  get port mapping
0x0a 0x4d 0x41 0x52 0x88 0x43 0x48 0xff 0x01 0xfd
Echo :
0xaa  0x13 p1 p2 p3 p4 p5 p6 p7 p8 s1 s2 s3 s4 s5 s6
s7 s8 pwd checksum
0xaa is the echo for receive command
0x13 is the data length [from p1 to checksum]
p1~p8 is the port mapping. 1~8 or 0[port off]
s1~s8 is the source status. 1: source exist 0: source off
pwd is the matrix status. 1: power on. 0: idle
example
0xaa 0x13 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x38

Ex 0x81 port select source 1 but set close. Echo 0xaa If the port value is the same, the output port will keep the video. Add 0x10 to source. The output port will re trigger (including off/on and do hdcp) For example: Now port1 select source 1 Port1 = 0x01 : video not change Port1 = 0x01 : video turn off/on and do hdcp again.
