1) PL-MCU-ENET-TTL-14-10B-1U
PMI Model Number PL-MCU-ENET-TTL-14-10B-1U is an Ethernet
microcontroller test box which allows for an Ethernet command to control
up to 140 parallel TTL output bits. Fourteen 15-pin D-Subminiature
connectors are provided to control fourteen 10-bit devices. +15VDC is also
provided on each connector to provide up to 50 watts total to the external
devices.
2) Ethernet Connection
The test box has the following Ethernet connection through the RJ45 Port on
the box:
IP Address: 10.1.10.212
Subnet Mask: 255.255.255.0
Default Gateway: 10.10.6.1
Connection Port: 3000
Note: If directly connecting a computer to the box, a crossover cable must
be used. If the computer and box are both connected to the same network, a
standard Ethernet cable can be used.

3) Ethernet Command Structure
Setting or Overwriting the Stored Data for an Output:
The Ethernet command structure is set up to input 14 text characters
containing either a 1 or 0.
The first 4 characters represent the address for which 10 bit connector is
being set.
The last 10 characters represent the data bits being set.

Sending Data to all Outputs Simultaneously:
Once the data is setup for the individual outputs, the data is sent to the
outputs and the output lines all change simultaneously when the Ethernet
command GO is sent.
Sending GO will update all 14 outputs with the stored data. All of the
outputs will retain their stored data so further changes can be made to any
number of outputs and sending GO again will only change the outputs that
have been updated since the last GO command was sent.
