1. General Function
The PH-IO24 (IOC) circuit card supplies the system with a serial interface, which conforms to RS-232C,
between external equipment such as the Maintenance Administration Terminal (MAT), Station Message
Detail Recording System (SMDR), Message Center Interface (MCI). Property Management System
(PMS). The relationship between the IOC card and the associated cards is as follows, when the CPU is
composed in a dual configuration.
Note:Firmware SP-3290 IO24 LV2 PROG-A is required in the Hotel system for PMS and Hotel Printer.

6. External Interface
As illustrated below, the “68PH S 2PORTS CA-A” cable is required to connect external equipment such as
the MAT, SMDR, MCI and PRT.
Figure 2-26   External Cable Connection for PH-IO24 (IOC)
 Securely insert the connector of the 68PH S 2PORTS CA-A into the appropriate MISC connector. Refer to the table listed below.
The relationship between the MISC connectors and the mounting 
slot of the IOC (PH-IO24) circuit card is shown below.
The type of cables varies depending on a connected terminal and/or 
whether modems are used or not. More detailed information on the 
connecting cables is explained in the “Installation Procedure 
Manual”.

1. General Function
The main functions of the PH-M22 circuit card are:
To collect the key setting information on the TOPU of the ISW and send the information to the ISW/
the other LNs, depending on the ISEL key setting on the ISW.
To collect various alarm information from all the IMGs/ISW and activate MJ/MN LED on the TOPU
display.
This circuit card is used for the IMX-U system.
