CHAPTER 8: COMMUNICATION OPTIONS
8.1
Overview
To supplement the built-in MJ1 and MJ2 serial ports, additional communication options are available.
This is accomplished by installing a COM module internal to the XL4 OCS controller.
8.1.1
Previous OCS controllers shared a serial port with the communication options. The XL4 has a
separate serial port which allows using both MJ1, MJ2 and the communication options
simultaneously. Internal to the XL4 OCS, there is a CPU board, and up to two installed modules.
Models HE-XC100 / HEXT251C100
have no installed I/O or COM modules. All other models
have an I/O module in Slot 1 and could have a user-installed COM module in Slot 2.
This chapter briefly describes the Modem COM module options. For detailed information
regarding these modules, please refer to the individual documents provided with the modules.
