tesmart.sh

This shell script can control network-enabled KVM switches by TESmart.

Disclaimer

This has only been tested with the 8-PORT HDMI 1.4 4K 30HZ device.

Dependencies

• awk
• bash
• bc
• hexdump
• netcat
• sed

Installation

With zinit

zinit wait lucid \
    as"command" \
    sbin"tesmart.sh -> tesmart" \
    atinit'alias tesmart="tesmart -c /path/to/tesmart-config.sh -H MY_TESMART_IP_ADDR"' \
  for pschmitt/tesmart.sh

After zinit does its thing, a new binary, tesmart, should be in your PATH.

Otherwise

Just make sure the dependencies are installed and fetch tesmart.sh.

Usage

# Get current input
./tesmart.sh get-input

# Switch to input #2
./tesmart.sh switch 2

# Mute buzzer
./tesmart.sh mute

# Unmute buzzer
./tesmart.sh unmute

# Set LED timeout
./tesmart.sh led-timeout 10
./tesmart.sh led-timeout 30
./tesmart.sh led-timeout never

# Enable/disable input detection
./tesmart.sh input-detection on
./tesmart.sh input-detection off

# Custom HOST/PORT
./tesmart.sh -H 10.78.81.10 -p 5001 get-input
# Alternative
TESMART_HOST=10.78.81.10 TESMART_PORT=5001 ./tesmart.sh get-input

# Network info
./tesmart.sh network-info

# Set network settings
./tesmart.sh set-ip 10.79.82.11
./tesmart.sh set-port 5011
./tesmart.sh set-netmask 255.255.252.0
./tesmart.sh set-gateway 10.79.82.1

# DEBUG
./tesmart.sh -d get-input
# Alternative
DEBUG=1 ./tesmart.sh get-input

Configuration

If you want to set up aliases for the input IDs you can create a config file.

Its location can be set with the -c CONFIG_FILE flag.

By default ./tesmart.sh will use ./config.sh.

This will enable the following workflow:

# Instead of ./tesmart.sh switch 5 you could do:
./tesmart.sh switch playstation_5

# Instead of ./tesmart.sh switch 4 you could do:
./tesmart.sh switch windows

Refer to the example config file for the syntax.

Warning

If you change your network settings via set-[ip|port|netmask|gateway] you need to reboot your switch. This can be achieved by toggling the on|off button.

If you screw these up, you'll need to correct the settings by either connecting via the RS232 port or fiddling with your computer's IP address settings.
