Product Description

The H2-SERIO is a DirectLogic-created Serial Module for an EBC System. This module may have also been sold under the manufacturing names Automation Direct and Host Automation. The H2-SERIO is a Communication Module for a DL205 I/O System. It is meant to be paired with an H2-EBC100. It contains three ports that are all RS-232s. Because it is attached to the H2-EBC100, seven other modules can be attached to the system allowing for up to twenty-four serial ports. It has a power consumption rating of 80mA @ 5VDC. It has a Baud rating of 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200. This device should be stored in a location between -20 to 70 degrees Celsius.

When the H2-SERIO module is connected to the base series, it supports functions such as K-Sequences, which will have the port respond to client devices that will run the K Sequence protocol. It also supports general-purpose software to allow the attached Do-more controller Input String Device, the STREAMIN, and the Output String Device, the STREAMOUT. For more of the features supported on the Do-more software and H2-SERIO module, refer to the attached chapter for the H2 series specialty modules. 

For more information on the H2-SERIO and the DL205 system it attaches to, please consult the datasheet created by DirectLogic for the H2-SERIO. Only skilled experts should attempt to install the H2-SERIO to prevent system damage or personal injury.

Frequently Asked Questions about H2-SERIO

What is the H2-SERIO?

The H2-SERIO module is a specialty unit in the DirectLogic 205 H2 series Do-more PLCs. It is primarily used to add more serial ports, such as RS-232 ports, to the Do-more base. The serial ports on the module will give the Do-more software on the local base five functions, such as Modbus RTU Server, Modbus RTU Client, Do-more Programming, General Purpose, and K-Sequence. 

What are the differences between the H2-SERIO and H2-SERIO-4 modules?

One of the main differences between the two units is the serial ports. The H2-SERIO model only supports the addition of three RS-232 ports to the H2 series base, while the H2-SERIO-4 model allows for the addition of two RS-232 ports and one RS-422 or RS-485 port. The recommended cabling between the two modules also differs as the H2-SERIO module will only use an RS-232 ZL-RJ12CBL-2 cable, while the H2-SERIO-4 modules can support the RS-232 cable or the RS-422 ADC L19853-x (Belden 8103) cable or the RS-485 ADC L19954-x (Belden 9842) cable.

Reviews For H2-SERIO

Internal Review

While the H2-SERIO unit is an excellent purchase due to its ability to add additional RS-232 ports, the H2-SERIO-4 model adds two RS-232 and one RS-485 or RS-422 port. Both modules can be connected to seven more H2-SERIO modules when using the local base to add twenty-four ports. - AX Control Tech
