6.3.7. View Connection State on the Output
Description: Viewing the output's connection results in different response length, because it depends on the
device. The response below refers to an MMX8x4-HT420M.
Format
Command {VC}
Response (ALL●<O1>●<O2>●<O3>●<O4>)CrLf ← (ALL 02 02 02 M02 02)CrLf
Legend: All <Ox> indexes show the corresponding output's connection state. If value <O1> equals 02 it
means that output 1 is connected to input 2. All <Ox> indexes are two digit ASCII characters (01, 02, 04,
etc.).State letters
Letter
L Output is locked
M Output is muted
U Output is locked and
muted
Explanation: I2 is switched to ll outputs.
6.3.8. View Crosspoint Size
Description: Shows the physical crosspoint size.
Format
Command {getsize}
Response (SIZE=<size>)CrLf
Explanation: The device reports that it has a video crosspoint with 8 inputs and 5 outputs.
INFO: IN MMX8x4-HT400MC and MMX8x4-HT420M models five outputs means four video and one
independent analog audio outputs).
6.3.9. Batch Switch Outputs
Description: The device is capable of switching multiple outputs exactly at the same time. To do this, the
normal switch commands have to be used. If the switch commands arrive at the device with less than 10
milliseconds delay, the commands are collected and changes the output connections together.
Required circumstances:
Switch commands have this format: {<in>@<out>}{<in>@<out>}
▪
▪ The delay between two '}' characters must be below 10 milliseconds
▪ No other command or junk character is allowed between switch commands
Affected outputs must not be locked
▪
If any of the above circumstances fail, then the commands will be processed separately and the output
connections will change one by one.

ATTENTION! The delay timeout applies for the receiving time of characters. Please note that if LAN
connection is used then the network may cause additional delays. This could result that batch switching
does not occur. Below example shows a command that resulted batch switching:

6.4. Network Configuration
6.4.1. Query the Current IP Status
Description: IP status can be queried as follows:
Format
Command {IP_STAT=?}
Response (IP_STAT=<type>;<ip_address>;
<subnet_mask>;<gateway_addr>)CrLf
Legend: <type>:
<ip_addr>:
<subnet_mask>:
<gateway_addr>:
Explanation: The device has a static (fix) IP address: 192.168.0.101; the subnet mask is 255.255.255.0, the
gateway address is 192.168.0.1.
6.4.2. Query the IP Address
Description: IP address can be queried as follows:
Format
Command {IP_ADDRESS=?}
Response (IP_ADDRESS=<type>;<ip_address>)CrLf
Legend: <type>: 0 = static IP; 1 = DHCP
<ip_addr>: IP address (four decimal octets separated by dots).
INFO: The response contains the fix IP address that is stored in the device even if DHCP is enabled; in this
case, this IP address is not valid.
Batch commands
→ {02@01}{05@04}
← (O01 I02)CrLf
← (O04 I05)CrLf
Example
→ {ip_stat=?}
← (IP_STAT=0;192.168.0.101;
255.255.255.0;192.168.0.1)CrLf
0 = static IP; 1 = DHCP.
IP address (four decimal octets separated by dots).
Subnet mask (four decimal octets separated by dots).
Gateway address (four decimal octets separated by dots).
