7.3.1 Communicating via MJ1 Serial Port
If a serial programming connection is to be used and the PC has a 9-pin serial COM port,
which is increasingly rare, there is nothing to install assuming the port already works. All that
is needed is a programming cable to go from the COM port to the OCS programming port.
If a serial programming connection is to be used and the PC does not have a COM port, a USB-
to-Serial adapter may be used. Horner offers the HE500USB600 USB-to-RS232 Serial
Adapter, which comes as part of the HE-XCK and HE-CPK programming kits. Drivers for it are
normally found automatically by the Windows operating system as long as an internet
connection is established. Otherwise, the drivers may be loaded from the Horner FTP site at
https://hornerautomation.com/support-files
Connect the PC’s serial port or the USB
-to-Serial adaptor to the port labeled MJ1 on the
XL4/XL4 Prime.
The instructions are similar to using a USB port, as shown above. In the Connection Wizard,
select the “Serial” option.
If communications are successful, the target indicator should show the mode of the controller
Target: yy(R) as shown in the
If the controller is not communicating, you may need to set the target ID of the controller in
Cscape or on the unit. The Target ID allows directing communications to a particular unit when
multiple units are connected via a CsCAN network. Units without CsCAN network ports respond
to any network ID and do not require the ID to be configured.
To check or change the ID on the XL4/XL4 Prime OCS, press the System Menu Key.
The first item in the menu is Set Networks. Pressing Enter allows you to view or modify the ID
of the unit.
