2. TECHNICAL INFORMATION
2-1. Activation of test mode
1. Hold down F.FWD + STOP + PLAY keys and press
POWER key, and when "Select Mode" is displayed, let go of
the three keys and, before 2 seconds is up, press STOP key.
(TEST MODE should be displayed.)
2. The test mode is released when power is turned off.
2-2. Activation of VTR mode
1. Hold down F.FWD + STOP + PLAY keys and press
POWER key, and when "Select Mode" is displayed, let go of
the three keys and, before 2 seconds is up, press PLAY key.
(VTR MODE should be displayed.)
2. The VTR mode is released when power is turned off.
2-3. Displaying ROM version numbers
1. Select the menu group F in the menu screen.
2. Move the cursor to the items shown below.
Sys Ver : SYS ROM version
Front Ver : FRONT MPU version
Servo Ver : SERVO MPU version
2-4. Displaying SUB MPU version numbers
1. Enter the test mode.
2. Select the menu group N in the menu screen.
3. Move the cursor to "SubMpuVer" and press ENTER key.
2-5. Displaying the voltage of battery
1. Enter the test mode.
2. Select the menu group N in the menu screen.
3. Move the cursor to "Battery".
2-6. Displaying the hed drum utilized time
1. Select the menu group F in the menu screen.
2. Move the cursor to the items shown below.
Dr Total : Total utilized time
Dr Search : Fast-winded time
2-7. Displaying the servo error history
1. Enter the test mode.
2. Select the menu group M in the menu screen.
3. Move the cursor to "ServoErr" and press ENTER key.
Note)
Servo error data is stored in the SERVO PCB's EEPROM mem-
ory. As the power is unstable immediately after being turned
ON, data written to the EEPROM at this time will be incorrect.
To ensure accuracy, the DA-98HR prohibits data from being
written to the EEPROM for 10 seconds after POWER ON. If an
error occurs just 10 seconds, the error data is not stored in mem-
ory. As a result, the servo error history stored in the memory
may differ from actual phenomena.

§
2-8. KEY PCB check mode
1. While holding the PLAY, STOP, F FWD and REW key
pressed, turn the power ON. In this case, all LED's light.
2. Press the STOP, F FWD, REW, PLAY or RECORD key.
All LEDs go out.
3. When each key is pressed, the corresponding LED lights.
2-9. How to use the built-in oscillator
1. Enter the test mode.
2. Select the menu group 2 in the menu screen.
3. Move the cursor to "Sine Osc" and press ENTER key.
4. Use the § and keys to select the output frequency (OFF,
440 Hz, 1 kHz, 10 kHz, 20 kHz, 20 Hz, wite noise).
(The level is full scale.)
2-10. Removing the FRONT MPU
As shown in Fig. 2-1, hold the FRONT MPU (KEY PCB:U6)
with the PLCC EXTRACTOR (P/N: 16910101) to remove it.
2-11. Removing the SYS ROM
Detach the socket cover to remove the SYS ROM (SYS
PCB:U011). To remove the socket cover, slide it as shown in
Fig. 2-2.

2-12. Checking the optional IF-AN98HR (A/D
board and D/A board)
To check the A/D board and D/A board, connect the EXTEN-
SION PCB (P/N : 5200353800) to each board.
Note)
The EXTENSION PCB cannot be connected to the SYS PCB.
2-13. Changeover of Reference level
By replacing jumpers on the A/D and D/A boards, you can set
the unit for one of the following reference levels.
Depending on the required reference level, plug in jumpers as
shown below. (See also figures 2-3 and 2-4.)

2-14. EXTERNAL CONTROL I/O
A CONTROL I/O connector is provided to enable external con-
trol of the DA-98HR. Transport control (+Chase) inputs and
related tally (+Lock) outputs are readily available.
To enable further capability of REC FUNCTION and INPUT
MONITOR inputs and its related tally outputs, the CONTROL
I/O also consists of signals for serial communication data.
The connector is a 37-pin D-sub and the output is an open col-
lector. Each transistor supports a current of up to 50 mA.
Input is at TTL level with 74LS240 of the LS-TTL used as a
buffer (with Schmitt trigger).
Power supplied from the DA-98HR is up to 50 mA at DC 5 V.
The control system data output is 32-bit serial sync, of which
8 bits are output in parallel simultaneously.
Input is 32-bit serial sync. The preceding 8 bits are merged
with the parallel input.
The pin assignment, serial input/output signal format and recom-
mended circuits for a controlling device are described here in
after.

For detailed schematics of the circuit, refer to Figs. 2-5 and 2-6.
The equivalent circuit (for one gate) of the transistor array

3-1. Flowchart of assembling
For parts that require caution when reassembling the mechanism
ass'y (especially critical gear meshes), a flowchart showing the
order of installation is showed below. Disassembly should be
performed in the reverse order of reassembly. As parts are indi-
cated using reference numbers, refer to EXPLODED VIEWS -3
and -4 (
pages 49 & 51) for identification.

3-2. Installation of the mechanical parts
For parts that require caution when reassembling the mechanism
ass'y(especially critical gear meshes), the following is showed.
[For order of installation, see flowchart (
page 19) and
EXPLODED VIEWS -3 and -4 (
pages 49 & 51).]
1. Installing COUPLING GEAR B (4-24), and COUPLING
GEAR A (4-30)
As shown in Fig. 3-1, install 4-24 and 4-30 so that the two
marks are visible.
2. Installing LOGIC CAM L (4-25) , and GUIDE CARRY
LEVER ASS'Y (4-29)
1) Install 4-25 so that hole 2 in 4-25 in Fig. 3-2 is aligned
with hole ` (Fig. 3-1) in the mechanism chassis. (Using
a 1 mm dia. rod, pass it through the both holes to see if
they are aligned with each other. Whenever checking
holes for alignment hereafter, employ this method.)
2) Similarly, install 4-29 so that hole 3 in 4-29 in Fig. 3-2 is
aligned with hole 1 (Fig. 3-1) in the mechanism chassis.
3. Installing LOGIC CAM R (4-27)
Install 4-27 so that hole 4 in 4-27 in Fig. 3-3 is aligned with
the holes (hole 3 in 4-29 aligned in 2) of 2 with hole 1 in
the mechanism chassis).
At this time, recheck that the holes aligned in 1) of 2 (hole 2
in 4-25 and hole ` in the mechanism chassis) are aligned
with each other.
