Description
The SER-HUB-C1 Serial Control System is a custom/field programmable serial device
controller. It can control any 2 serial devices and has 5 discrete outputs and 2 discrete
inputs. The SER-HUB-C1 product is comprised of 2 hardware items plus an optional 3
item and a Windows™ software GUI. The 2 hardware items are the following:
1. Model SER-HUB-2 Serial Hub
2. KP2B-HUB Serial Keypad
nd
2
KP2B-HUB Serial Keypad (optional)
When a key is pressed on either KP2B-HUB Serial Keypad, the Serial Hub sends a serial
string to the first serial device and then another serial string to the second serial device. It
will then set the 5 discrete outputs to the levels that were programmed. The Serial Hub is
custom/field programmable using the SER-HUB-C1 Windows™ software GUI. This allows
the user to specify any command or set of commands to be issued to the first and second
serial device when a specific button is pressed on either keypad. It also allows the user to
specify the levels of the discrete outputs for each keypad button. The SER-HUBWindows™ software GUI also allows the user to set the state of each individual for each
key pressed. The commands sent to the 2 serial devices can be any combination of ASCII
characters, hexadecimal bytes, wait times, and <CR>’s.

Serial Hub
Operation
1. The SER-HUB-C1 Serial Control System is designed to control 2 serial devices and
up to 5 contact closure devices all with the touch of one button on a keypad. The
Serial Hub listens to the 2 KP2B-HUB keypads and when it gets a command
indicating a button was pressed, it then sends out to the first serial device the serial
string corresponding to that keypad button, a serial string to the second serial
device, and then the Discrete Output levels are set. The Serial Hub then sends 10
commands to each Keypad telling the keypad how to light each LED. All these
commands are pre-programmed into the memory of the Serial Hub using the SERHUB-C1 Windows™ GUI software. The Serial Hub listens to the keypads and
responds to the key pressed by reading the strings and commands out of memory
and sending them out to the correct devices.

How To Use The Serial Hub Programmer
The first step to programming the Serial Hub with the Serial Hub Programmer is to connect
the Serial Hub to the computer that is running the SER-HUB-C1 Programmer via the COM
port you will select when you start the SER-HUB-C1 Programmer software. The COM ports
the Serial Hub Programmer supports are COM1 thru COM10.
After selecting a COM port, you will need to decide if you want to edit an existing
configuration file or create a new configuration file. A configuration file is all the information
that will be uploaded to the Serial Hub. Configuration files will have the file extension of
“.hrt”

. . . . . . . . . . . . . . . . . . . . . . . . . . . .
Selecting the Keypad Button to program
The drop down menu on the left will have all the choices for the 10-keypad buttons and
the 2 Discrete Inputs. The Discrete Inputs function exactly like a button on a keypad when
they transition from a Hi to a Lo state.
When the drop down menu is activated, all the settings on the right for the serial strings,
LED’s, and Discrete Outputs are saved into the currently selected button.
When a new button is selected via the drop down menu, all the settings associated with
that button are displayed on the right in their appropriate fields.
Specifying the baud rate for each serial device
Each serial device can have its own baud rate independent of the other serial device. For
each serial string, select the baud rate for that serial device using the Baud Rate drop
down menu.

. . . . . . . . . . . . . . . . . . . . . . . . . . . .
Specifying the LED states
For each keypad button and discrete input, the state of every LED can be specified. An
LED can only be in 1 state at a time so check the radio button for the state desired The No
Change state means that when the selected button is pressed, it will not change the
current state of an LED set to the No Change state. If that LED is on, it will remain ON. If
that LED is Off, it will remain Off. To set all the LED’s on a keypad to On, Off, or No
Change, use the All buttons on the left.
Specifying the Discrete Output states
For each keypad button and discrete input, the state of every Discrete Output can be
specified. A Discrete Output can only be in 1 state at a time so check the radio button for
the state desired The No Change state means that when the selected button is pressed, it
will not change the current state of a Discrete Output set to the No Change state. If that
Discrete Output is Hi, it will remain Hi. If that Discrete Output is Lo, it will remain Lo. To set
all the Discrete Outputs to Hi, Lo, or No Change, use the All buttons on the left.
Creating the Serial Strings
The strings to the serial devices can be comprised of ASCII characters, hexadecimal bytes,
and wait times embedded in the strings. The length of each serial string must not exceed
128 bytes. The current length of each string will be displayed in the String Length box.

Entering ASCII characters into the serial strings
Just start typing in either Serial Output text box to enter ASCII characters. You cannot
paste text and you cannot delete more than 1 character at a time.
Entering hexadecimal bytes into the serial strings
Enter Hexadecimal bytes by typing the hexadecimal byte into the box above the “Insert
Hex Byte” button. Then click “Insert Hex Byte” button. The Hexadecimal byte will be
inserted at the end of the current string.

Entering wait times into the serial strings
Waits can be entered into the serial strings by choosing the wait duration from the drop
down menu then clicking “Insert Wait” button. Each wait uses the space of 3 ASCII
characters in the overall string length. In this example, the ASCII characters “abcd” will be
sent out to the first serial device. Then there will be a 1 second wait and then the ASCII
characters “efghijklmnop” will be sent out to the first serial device. Then the ASCII
characters “ABCD” will be sent out to the second serial device. Then there will be a 5minute wait and then the ASCII characters “EFGHIJKLMNOP” will be sent to the second
serial device.
Entering Carriage Returns into the serial strings
To enter a Carriage Return <CR> into the serial string, just press the “Enter” key on your
keyboard.

Setup to Program Serial Hub
1. Install the SER-HUB-C1 Programmer software on the PC.
2.
Connect the provided power supply to the power port on the back right side of
the Serial Hub.
3.
Connect a straight through serial cable (provided) from the PC to the Serial Hub
Keypad A/Prgm serial port.
4.
Disconnect all other serial connections to the Serial Hub.
5.
Startup the SER-HUB-C1 program. (Located in Start menu)
6.
Create a New file or Edit an existing file.
7.
Do the following actions for each key on each keypad: Edit string commands for
Serial 1, Serial 2, set the Discrete Output levels, set LED states.
8.
IMPORTANT! You must wait 10 seconds after powering on the Serial Hub
before you can upload to the Serial Hub.
9.
IMPORTANT! You must not have any other programs running when you upload
the configuration to the Serial Hub. This may result in a failure to upload to the
Serial Hub.
10.
Save file and Upload
Uploading to the Serial Hub
To upload to the Serial Hub, make sure the Serial Hub is connected to the PC and is
powered on then simply click on the Upload button.
Loading or Saving Configurations
You can save or load a configuration file by clicking on the File menu and choosing the
appropriate icon. You can also create a new configuration file from the File menu.
Putting the SER-HUB-C1 into Operation
After you have successfully uploaded a configuration to the Serial Hub, disconnect the
Serial Hub from the computer and power it off. Connect the necessary devices to the Serial
Hub as specified above and apply power to the Serial Hub. You will see the LED’s on each
keypad light and then turn off 1 at a time in sequence 1-10. The Serial Hub is now ready to
receive commands from a keypad and send out the serial strings to each serial device and
to transition the Discrete Outputs.
