About the H2-SERIO-4

The H2-SERIO-4 module is considered a Serial Communications Module part of the DirectLogic 205 series from Automation Direct. This unit is considered a specialty module that can support a variety of serial devices. Consider that processing large amounts of serial data decreases the system response time. The H2-SERIO-4 Serial Communications Module contains 2 RS-232 ports with an RJ12 connector and 1 RS-422/485 port (5 position-terminal strips). A base module is a primary unit that will support the H2-SERIO-4 module; the base unit is labeled as an H2-EBC100 module; eight of the H2-SERIO-4 modules can be installed on the base unit to maximize the number of serial ports on the unit.

The H2-SERIO-4 module can be configured to enable a variety of valuable functions, such as:

  • Enable the port to respond to client devices running K Sequence Protocol.

  • Make the port available to client devices running Modbus/RTU protocol.

  • Make the port available for use by the Do-more controller’s Modbus Network Read (MRX) and Modbus Network Write (MWX) instructions.

For the RS-232 port, CTS, RXD, TXD RTS, and GND are the supported signals. The H2-SERIO-4 also supports 5, 50, 250, and 500 ms RTS transmission delay times.

For the RS-422 port (4 wire) TX+, TX-, RX-, RX+, GND signals are supported. For the RS-485 port (2 wires), RX+ and GND are the supported signals.

The maximum cable length for a 10BaseFL cable segment is 100 meters or 328 feet. You can connect a 10Base10FL cable to switches to lengthen the distance. Each switch can be attached to an additional 100 meters of cable. Two switches can be connected to extend the range of the cabling to 300 meters.

Frequently Asked Questions about H2-SERIO-4

What is the H2-SERIO-4? What does it do?

The H2-SERIO-4 is a Serial Communications Module. It supports several devices and can process a large amount of data to help decrease the system's processing times. 

What are the pin assignments for the H2-SERIO-4 RS-232 port?

There are six pins on the RS-232 port; the pin assignments are 1/0V for negative power connection, 2/CTs for clear to send, 3/RXD for receiving data, 4/TXD for transmitting data, 5/RTS for a request to send, and 6/0V for signal ground.

What functions can be used when the module is used with the Do-more software?

Five functions can be configured on the H2-SERIO-4 module. The following functions are the most common; Modbus RTU Client, General Purpose, Modbus RTU Server, Do-more Programming, and K Sequencing. Each of the aforementioned functions has a different purpose; for example, the K Sequence is selected when the user requires that the port responds to the client devices to run the K Sequence protocol. The General Purpose function will be selected to make the port accessible for use through the Do-more controller's Input and Output string to or from the device instructions. The Do-more Programming function is used to add the port to work with the Do-more Designer programming software. The remaining function purpose can be found in Chapter 7 of the H2-DM-M Instruction Manual on page 30 of chapter seven. 

Reviews For H2-SERIO-4

Internal Review
(5.0)

The best feature of the H2-SERIO-4 model is that the signals on this model are enhanced due to the addition of the RS-422/485 serial ports. The RS-422/485 ports add Data+, Data-, GND, TX+, TX-, RX-, and RX+ communication signals. The signals for the RS-232 port can be found in the attached H2-DM-M manual. - AX Control Tech
