WARNING : (For USA only)
This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used
in accordance with the instructions manual, may cause interference to radio communications. It has
been tested and found to comply with the limits for a Class A computing device pursuant to Subject J
of Part 15 of FCC Rules, which are designed to provide reasonable protection from such interference
when operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever measures may be required to correct the
interference.

1. INSTALLATION PRECAUTIONS
• Use a regulated power supply (24V DC, +/- 4 volts) to ensure correct operation without overload.
• Wire only the rated switches to the switch terminals, or damage could result.
• Wire only LEDÕs to the LED terminals, or damage could result.
• Do not exceed voltage rating to the relays, or severe damage could result.

2. GENERAL DESCRIPTION
The DIÐ100 and DIÐ110 interface boards are designed to be used in conjunction with the ICÐ100 Institutional
Communication System and ASÐ100A/ASÐ110 Control Stations. This will allow a control station operator to make or
receive calls from other stations with the push of (1) switch on custom or off-the-shelf control panels. Calls to or from
corresponding sub-stations can be announciated by flashing LEDÕs on the control panel or numerically in the associated
ASÐ100A or ASÐ110.

4.1 Principle of Operation
The DIÐ100 outputs dial pulse to the ASÐ100A/AsÐ110 according to control data transmitting from the MUÐ110. The DIÐ
100 also transmits a flashing or steady LED signal, relay control signal, etc. to the DIÐ110, and can periodically scan the
control panel switches.

7. PERFORMANCE TESTING
The DIÐ100 provides a diagnostic program for testing all LEDÕs, switches, relays, etc. to assure correct connection.
7.1 Test Program Initiation
(1) General Switch, LED, and Relay Wiring Confirmation Test Program
Wire the DIÐ100Õs CN-5 (No. 2 pin) to ground, and turn the power on.
(2) CALL-IN and BUSY LED Wiring Confirmation Test Program
Wire the DIÐ100Õs CN-5 (No. 2 pin) to ground, and turn the power on while holding down the PTT switch.
(3) Relay Wiring Confirmation Test Program
Wire the DIÐ100Õs CN-5 (No. 2 pin) to ground, and turn the power on while holding down the INDICATION RESET switch.
(4) Registered Data Confirmation Test Program
Connect the MUÐ110, and wire the DIÐ100Õs CN-5 (No. 2 pin) to ground, then turn the power on while holding down both the PTT and INDICATION
RESET switches.

10
7.2 Testing Contents
(1) General Switch, LED, and Relay Wiring Test
Press the switch to light the corresponding CALL-IN and BUSY LEDÕs, closing their relay contacts.
(2) CALL-IN and BUSY LED Wiring Test
All CALL-IN and BUSY LEDÕs are tested in sequence from 1 to 30. Holding down the PTT switch advances testing from one LED to the next at
one-second intervals. Releasing the PTT switch stops progress at the current LED.
(3) Relay Control Output Wiring Test
Relays 1Ð30 are tested for each of the DIÐ110 cards wired to the DIÐ100. Holding down the INDICATION RESET switch advances testing from
relay to relay at one-second intervals. Releasing the INDICATION RESET switch stops progress at the current relay until the INDICATION
RESET switch is pressed again.
(4) Registered Data Test
The corresponding registered data for each depressed switch is displayed on the ASÐ110 LCD display.
Select Switch : * 1 : ( X X ) X X (XX) XX : Register No.
8. PROGRAMMING
8.1 Equipment Connection
Direct select switches are programmed to a designated number. (Refer to pages 13Ð18 Programming Sheet.)

9. OPERATION
9.1 Calling
(1) Dial the desired station number with dial keys, or
(2) Press the corresponding SELECT switch on the control panel (instantaneous call).
9.2 Being Called (When in Continuous Call Tone Mode)
(1) The corresponding CALL-IN LED flashes simultaneously with a call tone. Flashing speed differs depending on the
priority level assigned to each station.
(2) To answer
(1) Lift the handset
(2) Press the PUSH TO TALK key, or
(3) Press the SELECT switch corresponding to a flashing LED. (When there are two or more simultaneous
incoming calls, as indicated on the panel, by simply pressing this switch, the desired station can be
instantaneously selected for answer.) The calling partyÕs CALL-IN LED and BUSY LED will both light.
9.3 To Terminate the Conversation
(1) Replace the handset,
(2) Press the C/# key, or
(3) Press the conversation partnerÕs SELECT switch as indicated by its corresponding CALL-IN LED.
9.4 Other Functions
(1) BUSY LED
This LED lights to indicate that its station is busy. When speech links wishing to use are occupied, however, a
busy tone is heard from the called station even if its BUSY LED does not light.
(2) INHIBIT switch
Setting this switch to ON disables all SELECT switches. Operations by the control stationÕs dial keys or
PUSH TO TALK key are still possible.
(3) Indication test switch
As long as this switch is pressed, all LEDÕs on the control panel light connected to the DI-110.
No test can be performed during conversation or while receiving CALL-IN.
