Overview of the Service Port

The service port is a serial port for use in connecting from a PC to the print controller via an RS-232C serial
cable to control the print controller using HyperTerminal, a terminal communications program.
This print controller supports for input/output operations of HyperTerminal from when the printer system
BIOS boots up, thus making it possible to control the progress in initialization and system test (POST: Power
On Self Test) by BIOS, which, when an error occurs at the system boot time, assists you in determining
where error conditions may exist.
You can also use HyperTerminal to switch to the memory test functions of BIOS or to boot service DOS.
Service Port Operating Environment
The following is required to use the service port:
• Computers running on Windows
• HyperTerminal (terminal communications program)
• RS-232C serial cable (terminated in a female 9-pin D-Sub connector on both ends)

2.
