7. PERSONAL COMPUTER CONNECTIONS
The DI-1616 interfaces the power amplifier with the personal computer, and lets the computer display the
power amplifier status or set the signal level on the computer's screen. Up to 30 DI-1616s (240 power
amplifiers) can be controlled. Although the digital processors DP-0202 and DP-0204, and the matrix unit DX0808 can be controlled simultaneously, the total number of all connected units must be up to 30 per system.
Both RS-232C and RS-485 interface standards can be used. The communication speed is 192,000 bps.
●
RS-232C
Use this port when the system includes only one DI-1616 unit and the distance between the unit and
personal computer is shorter than 10 m.
●
RS-485
Use this port when using only one DI-1616 and the distance to the computer exceeds 10 m or when using
plural DI-1616s or when using the DI-1616 in combination with the DP-0202, DP-0204, and/or DX-0808.
7.1 When using the RS-232C
Because only one unit is connected, the unit number is 1. Set DIP switches in the front compartment for [0][0],
and connect the unit to the personal computer as shown in Fig. 1. Use a straight cable for the communications
cable.
Connect the computer's RS-232C connector to the unit's RS-232C connector (9-pin D-sub connector) located
in the front compartment.
Note
The RS-232C is a one-to-one communications method. However, as a guideline, the maximum transmission
distance is 10 m. If exceeding 10 m, it is recommended that the RS-485 port be used even though only one
unit is connected.

7.2 When using the RS-485
Because multiple units are controlled, a unit number must be preset for each unit. To preselect the DI-1616 as
unit No. 1, set DIP switches in the front compartment for [0][1]. Refer to p. 8 "8. UNIT NUMBER AND
COMMUNICATIONS PORT SETTINGS" for DIP switch setting.
Figure 2 shows the example of connection between the personal computer and each unit. Note that an
adaptor to convert the RS-232C port into RS-485 type is required because personal computers are usually
equipped with only the RS-232C port. Connect the personal computer's RS-232C port to the female RS-485
connector on the rear panel of equipment of unit No. 1 via the conversion adaptor. Connect other units as
shown in Fig. 2. Up to 30 units can be connected.
Notes
●
When the system employs the DI-1616 together with the DP-0202, DP-0204, or DX-0808, do not select the
DI-1616 as unit No. 1.
●
Both DP-0202 and DP-0204 incorporate a RS-232C/RS-485 converter function. Therefore, when the DP0202 or DP-0204 is designated as master unit, it can be directly connected to the personal computer
without using the conversion adaptor. In this case, make the same connection as for the RS-232C control
(see Fig.1).

8. UNIT NUMBER AND COMMUNICATIONS PORT SETTINGS
When using two or more DI-1616s or when using the DI-1616 together with the DP-0202, DP-0204 (both
digital processors) and/or DX-0808 (matrix unit), different numbers must be given to different equipments so
that the personal computer transmits data to each connected equipment. This number is a unit number,
which must be preset in consecutive numbers of 1-30.
●
Unit number setting
1. Open the front compartment using a screwdriver.
2. Switch on the power.
3. Press the unit number display key [UNIT ID] on the front panel.
4. Using two DIP switches in the compartment, set a unit number.
●
Example
Set the switches for [0][1] if a unit number is 1, and for [2][5] if No. 25. The set number flashes on the display.
●
Notes on equipment of unit No. 1
The DIP switches on equipment of unit No. 1 can be set for [0][0] (RS-232C port) or [0][1] (RS-485 port) to
allow selection of the communications port. Referring to p. 6 "7. PERSONAL COMPUTER CONNECTIONS",
select either port. In either case, a number [1] flashes on the display.
●
Starting values
The unit is factory-preset to unit No. 1 ([0][0], RS-232C port). Take care not to assign the same unit number to
different units. To confirm the unit's unit number, press the unit number display key on the front panel.
9. BACKUP BATTERY REPLACEMENT
