Sony was one of the first to apply DAT technology to PCM data recorders. With the PC204A/208A, Sony condensed its numerous new technologies in a unit and introduced the DAT double speed recording/playback to the world.
The PC216A is the world's smallest and lightest 16-channel data recorder (A4 size, approximately 4.5 kg), based on high performance and efficiency of PC204A/208A.
Simultaneous recording up to 32 channels' data has been realized by using a channel expansion unit PCCX32.
Moreover, in the sync mode, simultaneous recording is possible up to 32 channels with two PC216As and up to 64 channels with PC216A and PCCX32. The PC216A can also serve as a stand-alone digital data recorder with high speed serial digital data I/O in addition to the parallel digital data output and the digital I/O channel using LSB.
In addition to its excellent performance in field-use, the PC216A can serve for a wide variety of use in measurement field.
The PC216A became the world's smallest and lightest 16-channel data recorder (A4 size, approximately 4.5 kg) by using the DAT second generation technologies including highly reliable mechanism and large-scale integrated electronics.
The channel expansion unit PCCX32 allows the simultaneous data recording and playbak up to 32 channels at maximum.
Multiple band/channel mode capable of 2-channel*, 4-channel, 8-channel, 16channel, or 32-channel recording/playback is provided. (32-channel mode is available only when the PCCX32 is used.) *Normal speed only In addition to regular recording/playback, the PC216A can play back the data recorded on a conventional audio DAT recorder using 2-channel/48 kHz
sampling.
By synchronizing two PC216As, simultaneous 32-channel data recording is enabled in 16-channel frequency band. By synchronizing two PC216As with PCCX32s, simultaneous 64-channel data recording is also enabled in 32-channel frequency band.
In previous DAT systems, the total bandwidth provided by all channels was 40 kHz. This unit possesses an 80 kHz band in the double speed mode, as the tape speed and drum rotation have been doubled.
The PC216A provides up to 5 kHz for each of 16 channels, and up to 2.5 kHz for each of 32 channels.
Playing back at the double speed a tape recorded at the normal speed reduces the playback time by half. Alternatively, playing back at the normal speed a tape recorded at the double speed allows desired phenomena in the data to be reproduced at a slower rate.
A new tape mechanism developed for thin DDS (Digital Data Storage) tapes, enables a recording time of 180 minutes (normal speed) or 90 minutes (double speed).
The recording mode can be either Analog Mode (analog input/output) or Digital Mode (digital input/output).
• In Analog mode, the output of the parallel digital data and the input and output of the LSB digital data are available besides the input and output of the main analog data.
The data input in analog can be output in a 16-bit parallel digital data format. The input and output of the LSB digital data is available for one channel by utilizing the Least Significant Bit (LSB) of each digital word, which facilitates the recording of binary signals such as rotation pulses and timing signals.
• In Digital Mode, input and output of the serial bit stream is possible. The transfer rate in sync mode is 1.536 Mbps (normal speed) or 3.072 Mbps (double speed).
In addition to the analog main data channels, digital input/output is available by utilizing the Least Significant Bit (LSB) of each digital data word. The LSB channel facilitates the recording of binary signals such as rotation pulses and timing signals.
The PC216A and the PCCX32 operate on AC, DC power, or an optionally builtin battery pack, allowing the unit to be used as easily outdoors as indoors. When the AC and external DC power supplies are used jointly, the AC source is given priority, that is, the AC source is automatically selected for the operation. Should the AC power supply be interrupted, the unit instantaneously switches to the external DC power supply without any interruption in the operation. When the external DC power supply and the battery pack are used jointly, the external DC power supply powers the unit, with the battery pack acting as a back-up.
The playback circuit and the LCD backlight can be turned off during recording to reduce power consumption to a minimum.
The unit has been designed with an emphasis on durability, making it suitable for outdoor use.
Equipped with a 4-head drum, the unit can play back data immediately after recording with the RAW function. During recording, errors are detected and indicated on the display panel.
With a 16-bit linear-quantized pulse-code modulation (PCM) system, the PC216A offers a wide dynamic range of more than 80 dB. Since extra head room (2.5 dB) is provided above the reference level (±100%* or 0 dB) to capture signals within the given dynamic range, input signals which are in the vicinity of the reference level can be recorded without distortion, and the input level can be set easily.
All 16 bits of the PCM area are used for data. Announcements, amplifier setting information, and index information are stored in a separate sub code area.
* ±100% level, for example, is the level that corresponds to ±1 Vp input signal when the input range is set to "1V", or ±2 Vp input signal when the input range 1is set to "2V", and so on.
Multiplexing of data generated by simultaneous AD conversion of analog signals, together with careful handling of analog circuit, makes it possible to reduce the inter-channel phase difference to less than three degrees.
When the power is turned ON, when the cassette is inserted, or in SLF CHK mode, the DC offset and the gain errors are automatically corrected by the builtin DSP (Digital Signal Processor). Any drift due to aging is eliminated, and high precision recording and playback can be performed without the need for adjustment.
The user can select various test signals; ±100% AC, ±100% DC or 0 V. These signals can be monitored at the data output connectors or recorded onto tape to be used as reference signals.
The PC216A display panel incorporates a wide angle view LCD with a highly luminescent backlight, providing a high degree of readability. The bar meter can be displayed using either a percentage scale or a dB scale, as required.
Two search targets can be stored in the memory by marking location points on the tape using special keys for the simple search.
This mode serves to stop the ventilation fan when the unit's internal temperature is low enough. This function makes the PC216A well-suited for applications such as acoustic measurement in an anechoic chamber when silence is required.
The remote control unit PCRM22 has a display almost identical to the main unit's display. Data input level, tape remaining and error check message are just a few of the functions provided. Furthermore, as the remote control interface conforms to the RS-232C standard, it is possible to use a host computer to control the main unit.

During recording, the MIC LED will light when voice annotation is input from the microphone. The brightness of the LED varies according to the microphone input level. During playback, the MIC LED lights according to the voice annotation level (ANN/DATA switch is set to ANN) or signal level of the monitored channel (ANN/DATA switch is set to DATA).
The bar meter indicates the level for each channel.
• When the percentage scale is selected, the data signal level is displayed as a percentage (+100%, 0%, -100%, etc.) relative to the reference level (±100%).
The reference level (±100%) is defined as the level 33% below the full scale of the A/D or D/A converters. When the range setting is 1V, for example, the input level of ±1 Vp indicates ±100%.
In the case of DC signal or signals with slow amplitude change, a signal level (the peak level) of each channel is indicated by a single LCD segment. If signals with faster amplitude change are displayed, the level indications look like bars indicating positive and negative peak values. Therefore the percentage scale is useful to monitor the signals with DC offsets.
• When the dB scale is selected, the data signal level is displayed as a dB value (+2 dB, -6 dB, -20 dB, -∞ dB, etc.) relative to the reference level (0 dB).
The reference level (0 dB) is defined as the level 2.5dB below the full scale of the A/D or D/A converters. When the range setting is 1V, for example, the input level of ±1Vp indicates 0 dB.
The level is indicated in one direction regardless of the signal polarity. The percentage scale or the dB scale can be selected by using the dB/%
• The percentage scale of the dB scale can be selected by using the dB/% switch on the rear panel (Refer to 2-2 (2) ). The dB scale is suitable for acoustic measurements, while the percentage scale is suitable for measuring the data signals, which include a DC
component, i.e. stress, distortion, etc.
The OVR marks for each channel lights up when the signal level is at the over range. When the percentage scale is selected for the bar meter display, the OVR marks positive <+> or negative <-> side or both sides light up according to the signal level. The lighting mode can be selected between real-time and peak-holding. To select the mode, use the HLD/RAL switch on the rear panel (Refer to 2-2 (2 )).
Any three digit number can be used as an ID number for discrimination, and it can written to any portion of the tape during recording. This ID number is shown on the ID display section.
In the SOURCE mode, the ID number displays the source index (values in the machine). In the TAPE mode, the ID number displays the tape index (Values recorded on the TAPE).
The auto-increment mode is set when A is displayed on the right side, and each time a recording operation is stopped the ID number increases by one.
Warning messages concerning low DC voltage, mechanical malfunction, condensation in the machine and data errors are displayed in this section. For details, refer to section 3-6.
Displays the channel number of monitored channel.
Displays, for each channel, the values for the monitored channel input range either in the machine (SOURCE mode) or on the tape (TAPE mode).
Display | 20 V | 10 V | 5 V | 2 V - | 1 V | 0.5 V |
---|---|---|---|---|---|---|
Input range | ±20 Vp | ±10 Vp | ±5 Vp | ±2 Vp | ±1 Vp | ±0.5 Vp |
±20 Vp, for example, is the range which becomes the reference level (±100% or 0 dB) when the +20 V peak or -20 V peak voltage is input.
In the REC, E-E and REC-PAUSE modes, displays only the source data (Count, Remain and S-TIME). In the PLAYBACK, PLAYBACK-PAUSE, FF, REW and the STOP mode, by pressing either the SOURCE key or the TAPE key, the following displays or values can be selected.

1 Turn the power switch ON, and insert a cassette.Because signals are recorded on the tape during the self-check, use a spare cassette for this purpose.If the cassette is record-protected (the tab hole is open), it will be automatically
ejected and "SLF" will be displayed on the ID display section until the STOP key is pressed.
2 To enter the SELF-CHECK mode, press the FF key while holding the REC key down.
The symbols "CAL" and "SLF" will be displayed in the ID display section in sequence, and a self-check will be performed.
3 If no cassette is inserted in SELF-CHECK mode, only calibration of DC offset and gain are performed. Required 20 seconds approx, for PC216A only or 25 seconds approx, with PCCX32.
If no error has been detected by the SELF-CHECK mode, the symbol "SLF" will be extinguished. If an error has been detected, error code will be displayed in the ID display section.
There might be a case that each error code is displayed other than during the SLF CHK mode. When the error code is displayed even though any countermeasures have been taken, please contact a Sony service center.
Power supply failure. Check that the voltage is within the specified range, or use a fresh battery pack.
An incorrect command has been received from the host computer.
Displayed when loading and playing back a tape which was try to playback a 2channel mode recording tape by the ×2 speed, or a tape recorded in not provided channel mode.
Displayed when a tape which has been recorded in a different modes (analog/ digital) is played back. Select the correct mode for the tape. (Refer to 11. DIGITAL DATA I/O.)
Displayed when an error is occurred during sync mode. (See 6. Synchronization Mode.)
Displayed when an error occurred during operation of the unit. Reconfirm the cable connection.
Displayed when the operation has been stopped due to a dew condensation.
Mechanical malfunction. Press the EJECT button and remove the cassette, or turn the POWER switch on the rear panel ON and OFF.
Communication error between the CPUs in the unit. Turn the power switch on the rear panel ON and OFF.
Head writing or reading is faulty. Replace the tape with a new one, or clean the heads with the supplied cleaning cassette.
The A/D converter section or input amplifier system is faulty.
The D/A converter section or output amplifier system is faulty.
The overall signal processing of the recording/playback amplifier system is faulty. The heads may be dirty, in which case error codes for all the channels will be displayed. Clean the heads with supplied cleaning cassette.
If a malfunction occurs in the unit, the appropriate symbol will be shown by the warning display in the CAUTION area.
In this situation, perform the measures outlined below before operating the unit further.
This is displayed when either the battery voltage or the external DC voltage has dropped below the required level.
Replace the battery pack with a charged one, or check the DC power supply (11 to 30 V).
To prevent malfunction, and for longer operating times, replace the battery pack with a fully-charged one as soon as the low DC voltage symbol is displayed.
The durability of NP-1B (new and fully-charged) for continuous operation are as follows:
NORMAL mode | P-SAVE mode | |
---|---|---|
PC216A | Approx. 40min | Approx. 60min |
PCCX32 | Approx. 80min | Approx. 150min |
This is displayed when the drum or reel malfunctions, or if the cassette has not been loaded properly.
This is displayed when the moisture is condensed on the head drum caused by using the unit in an excessively cold or humid location, or moving from a cool to a warm location.
During this display, the tape will stop and the condensation will be removed by the internal heater.
Do not use the unit until the warning display has been extinguished.
Having a 4-head drum, the unit's read-after-write (RAW) system enables recording and playback to be performed (track recorded is immediately traced by two playback heads) simultaneously, and writing errors to be detected. If writing errors are detected by tracing the track, an error indication is shown on the display.
Causes of the writing error are either scratches or wrinkles on the tape, or head clogging (dirt build-up on the heads). Therefore, if writing errors occur, replace the cassette or clean the heads as appropriate using the supplied cleaning cassette. When the error check mark is randomly displayed, the analog data can be reproduced by the interpolation function of the unit.
This error message will also be displayed when an unrecorded portion of the tape is played back. If the error mark is persistently displayed beyond that section of tape, replace the tape or perform head cleaning.
If the error mark is still displayed, contact a Sony service center.
The DC offset and gain errors are automatically calibrated at POWER ON and in the self-check mode. When a self-check is conducted without a cassette inserted, only calibration is performed.
The condition in which the tape and the drum have reached the specified speed during recording or playback is called "Servo Lock". Locking the servo takes a couple of seconds after start up. The servo lock condition cannot be reached until approximately one second after the FWD key is pressed, and approximately 0.5 seconds after pause release. Data is not recorded or played back until this time.
The front panel PNL LOK key is used to prevent the accidental operation of the front panel during recording and the subsequent interruption of the recording of important data.
Press the PNL LOK key continuously for about two seconds. The PNL LOK key LED lights, and most of the front panel keys are locked. To release the lock, press the PNL LOK key again for two seconds. The PNL LOK key LED will be extinguished, and the lock released.
With the following exceptions, the various tape running modes can be directly entered without the need to press the STOP key first.
• E-E mode
This mode can only be entered from the STOP mode (by pressing the REC key).
• REC mode
This mode can be entered from the STOP mode, by holding down the REC key and pressing the FWD key. Also from the E-E mode, by pressing the PAUSE key twice.
The power save mode is provided to minimize the power consumed during recording. To enter the power save mode, set the NORMAL/P-SAVE switch to P-SAVE. During this mode, the backlight of the LCD display and the playback circuitry will be turned off.
When the mode has been changed from NORMAL to P-SAVE mode, noise may come out from the OUTPUT connectors in a moment. Of cource, these do not affect the data recorded on tape.
During playback, the index (ID number, counter, address, time) and the setting of input RANGE can be switched between the SOURCE mode (displaying the source data) and the TAPE mode (displaying the tape data), by pressing the TAPE or SOURCE key.
The switching sequence and contents are as follows.
The machine automatically goes into the source mode display during the REC, REC-PAUSE or E-E mode.
When these modes are switched to the FWD mode again, the display mode (source or tape) of the previous FWD mode is automatically switched on. If channel mode, input range and ID number are newly set in the STOP mode, the display automatically changes to the SOURCE mode.
This mode is designed to reduce the noise level by stopping the ventilation fan when the unit's internal temperature is low. The FAN CONTROL mode is foggled by pressing the DOWN key with the UP key held down.
In the FAN CONTROL mode, the rectangular mark lights or blinks according to the unit's internal temperature as follows:
The period of time before the fan stops depends on the unit's internal temperature and the ambient temperature. Generally, however, it takes 15 to 20 minutes (in P-SAVE mode) from the power ON for starting (cold start) till the fan driving when the ambient temperature is 20°C.
When the power is first switched ON, the following display is shown. Before commencing recording or playback, set any necessary values.
The channel mode can be switched in turn as 2 → 4 → 8 → 16 → (32 → ) 2, when the CH/NEXT key is pressed while pressing the SPEED key. The frequency band and recording time changes according to the channel mode and the tape speed as follows.
Frequency Band | Recording Time | |||||||
---|---|---|---|---|---|---|---|---|
Tape Speed | 2 channel mode 4 channel mode 8 channel mode |
16 channel

Normal Speed | DC to 20 kHz | DC to 10 kHz | DC to 5 kHz | DC to 2.5 kHz | DC to 1.25 kHz | 120 min | 180 min | |
2 × Speed | DC to 20 kHz | DC to 10 kHz | DC to 5 kHz | DC to 2.5 kHz | 60 min | 90 min |
Select the tape speed (normal or double speed) with the SPEED key. The selected LED (× 1 or × 2) lights green.
The monitored channel number is indicate here. Each pressing the CH/NEXT key the next channel is selected, even during recording or playback. On the other hand, by pressing the UP or DOWN key a channel having higher or lower channel number can be selected respectively.
The input range of monitoring recording amplifier is displayed on the RANGE area.
To alter the input range, perform the following steps:
The ID number can be any three digit number, and can be set in STOP or E-E mode.
1 Press the ID key to enter ID setting standby mode. On the ID display section, the digit which can be altered will blink.
3 Press the CH/NEXT key to shift to the other two digits and set their values.
The ID number will increase each time the ID key is pressed during recording or recording pause.
During ID setting standby mode (step 3 above), press the CH/NEXT key to start the square frame of the A mark blinking. Then select ① of the following by pressing the UP and DOWN keys, and press the ID key once again to light up the A mark.
In this mode, each time a recording session is stopped the ID number increases by one. The next session will be assigned the new ID number.
To set the internal clock:
1 Use the tip of a mechanical pencil, or a similar object, to press and release the recessed CLOCK button. The year, month and day can now be set. Using the UP and DOWN keys, set the value of the blinking digit. Press the CH/NEXT key to shift to the next digit.
The unit is equipped with a built-in test signal generator which generates ±100% AC (500 Hz for normal speed, 1 kHz for double speed), +100% DC, -100% DC and 0V test signals during the E-E mode. In test signal mode, by entering the REC mode the generated test signal can be recorded onto the tape as a reference signal.
If recording starts without exiting the TST SIG mode, the test signal will be recorded on each channels, regardless of the signals present at the INPUT connectors.
Press the RESET key to reset the counter to 000.
3 Place the unit in recording mode by pressing the REC and FWD keys at the same time.
The data signal along with the index and amplifier settings is recorded on the tape.
The start ID is recorded and the SID mark is displayed for 15 seconds.
* E-E (E to E) mode:
The recording/playback amplifier operates, and the input signal is directly output from the recording system to the playback system.
Voice annotations can be recorded alongside the input data. Connect the supplied microphone to the MIC jack. Press the switch on the left side of the microphone to turn it on. Release the switch to turn it off. By doing so, only necessary voices can be recorded.
The recording level is adjusted automatically. The sound will not be output during recording, only during playback. The MIC LED will make sure that voice annotations are being correctly recorded. The brightness of the LED will change according to the microphone input level or voice annotation playback level.
The analog data signal can be monitored during recording by connecting an optional BNC cable to the MONI connector. Press the CH/NEXT key to select the channel to be monitored.
The recording pause mode is set by pressing the PAUSE key in E-E mode. By pressing the PAUSE key again, or by pressing FWD, recording will start after a short delay. If the recording pause mode has been set by pressing the PAUSE key during recording, the pause mode can be released by pressing the PAUSE or FWD key.
The counter displays time elapsed in hours, minutes and seconds. In the double speed mode, the counter turns over at twice the rate of the normal speed mode. When a different cassette is inserted, the time count begins from 0 hours, 00 minutes, 00 seconds. If the power switch is turned OFF while the cassette is still in the machine, the time value is preserved. Press the RESET key to set the tape counter value to zero.
Press the SOURCE key once to show the amount of tape remaining on the counter display.
This remaining time is displayed in hour/min.
Press the SOURCE key to display the source date in years, months and days. Press the SOURCE key again to display the source time in hours, minutes and seconds.
Press the SOURCE key once more to return to the counter display.
To perform ID searches during playback, an ID signal should be recorded for more than 2 minutes (at normal speed) at the beginning of the target. In addition, as the START ID is recorded for 15 seconds (at normal speed), a recording interval of less than 2 minutes (at normal speed) may cause targeting errors during search operations.
1 Using the optional BNC cable(s), connect each channel OUTPUT connector to the analyzing device.
A load impedance of at least 600 is recommended.
The maximum output current is 10 mA (100 load for output ±1 Vp).
The LED (× 1 or × 2)of the selected tape speed lights. When the speed at which the tape was recorded and the speed at which the tape is played back match, the LED will light green. If the tape speeds differ, the selected tape speed LED will light orange.
The unit will enter the PLAYBACK mode and the signal recorded on the tape will be played back.
Since the amplifier setting data (channel mode and input range) during recording are simultaneously played back and the display is automatically set under the same condition as in the recording mode, the setting condition during recording can be checked easily.
The active channels differ depending on the channel mode. Refer to the CH indication on the front panel.
By setting the ANN/DATA switch to ANN, the voice annotations recorded are played back on either the speaker or earphones. Adjust the volume using the VOL knob.
By setting the ANN/DATA switch to DATA, the data signal of the channel which has been selected on the monitor is played back on either the speaker or earphone as sound.
Press the RESET key to return the tape counter to zero.
Use the TAPE mode during playback to display the tape index (recorded on the tape) and amplifier information.
• To enter the TAPE mode, press the TAPE key. The display shows the tape index. Each time the TAPE key is pressed, the display changes as shown below.
• To enter the SOURCE mode, press the SOURCE key. The display shows the source index. Each time the SOURCE key is pressed, the display changes as shown below.
The amplifier setting data (channel mode and input range) is recorded on the tape as sub-code information, and read out in playback. The channel mode is automatically set to the same as recorded, and the input range of each channel at recording can be confirmed.
According to the channel mode, the bar meters for active channels only are indicated.
If it is necessary to adjust the level of the playback signal output from the PC216A, use the supplied precision screwdriver to adjust each channel's level adjustment potentiometer, located on the side panel.
The valid level adjustment potentiometers differ depending on the channel mode. Refer to the CH indication (see 2 on page 2-14) on the display panel.
The playback pause mode is set by pressing the PAUSE key in STOP mode. By pressing the PAUSE key or FWD key once, playback will begin after a short delay. The playback mode can be restarted by pressing the PAUSE or FWD key, if the playback pause mode has been set during playback using the PAUSE key.
The PC216A is capable of 2-channel mode recording and playback (normal speed only). With this function, the machine can play back a tape recorded on a 2-channel general audio recorder (only when 48 kHz sampling).
Since sub-code systems of the PC-Series and audio DAT recorders are incompatible, only the main data signal can be played back by the PC216A.
Required data can be quickly accessed using the search function.
This function allows any position to be marked on the tape and stored in memory for use in later searches.
If no specific mark is set during recording, the position at which recording began and the position at which recording was stopped will be automatically stored in memory as MARK-1 and MARK-2 respectively.
This facilitates returning a tape to the start position of recording quickly for review, and searching for the end position of recording to continue recording. When the MARK-1 key is pressed, the tape position at this time will be stored in memory. When the MARK-2 key is pressed, the position at this time will be stored temporarily. However, it is replaced automatically by the stop position when recording stops.
• During Playback
The MARK-1 and MARK-2 keys can be used to store two desired positions in the memory.
Pressing the same key a second time will overwrite the previously stored position.
When the SEARCH key and then MARK-1 or MARK-2 key are pressed in sequence, the stored position will be searched for and the tape will stop at that position.
Press the SEARCH key and then the ID key. The ID SEARCH standby mode allows targets to be set. Use the UP and DOWN keys to set the ID value blinking on the display, then press the CH/NEXT key to set the next digit.
2 By pressing the ID key once again, the target ID will be searched for and the tape will stop at the beginning of the ID.
During the first 15 seconds of recording, a START ID is automatically recorded on the tape to allow the position of the start of recording to be accessed swiftly. Press the SEARCH key, then either the FF key or the REW key to start forward START ID searching or reverse START ID searching respectively.
Press the STOP key to exit the search mode.
Manual Search is used to search for the target point using the displayed index (i.e. address, time, etc.) in the forward and reverse directions on the tape. The forward manual search mode is set by pressing the FF key during playback. The reverse manual search mode is set by pressing the REW key. The manual searches are conducted at 16× normal tape speed.
The PC216A can perform the recording and playback of the analog data signal up to 32 channels at one time, using the optional channel expansion unit PCCX32.
Lights when power is supplied to the unit, and blinks when the power voltage lowers the specified level.
Turn the power ON/OFF with the POWER switch on the PC216A rear panel.
Displays the analog data signal level of channels 17 to 32. Using the dip switches on the PC216A rear panel, either percentage display or dB display is selected. Set the switch to lower position to display in percentage scale (10 %, 50 %, 100 %, 125 %) in the left, and set to upper position to display in dB scale (-20 dB, -6 dB, 0 dB, +2 dB) in the right. In either case, the uppermost LED will light up when the level is beyond the range of each channel.
Since the bar meter of the PCCX32 indicates the level in one direction regardless of the signal polarity, even when the level is displayed in percentage scale, the indication may differs from that of the PC216A. The analog data signal level for channels 17 to 32 can also be displayed on the PC216A. Refer to 2-1 (2) .
Used to input the analog data signals of channels 17 to 32.
Lights during the 32-channel mode.
Insert the supplied AC power pack or optional battery pack here.
Press the knob in the arrow direction to eject the battery pack/AC power pack.
Chassis ground.
This fan cools the interior of the unit. It should not be blocked.
The DC fuse is inserted here.
Use only fuses specified for use with this unit.
External DC power (11 V to 30 V) can be supplied to this connector.
Connect a supplied connection cable.
Used to output the analog data signals of channels 17 to 32.
Used to increase and decrease the output level for each channel (17 to 32). Refer to 2-3 (2 ).
3 Using the supplied combining frames (totally 4 for the front and back, right and left), attach the PCCX32 to the PC216A, so that will make it easy to carry and fix onto a base rack. Refer to the following for attachment.
5 Mount the PC216A onto the PCCX32. With the guard sheet sides facing inside, temporarily fix the combining frames with the supplied four small binding screws ⊕B3 × 12 (black). The four combining frames are all same type.
Fix all four combining frames temporarily in the same way.
6 After temporarily fixing the four frames, fix them securely.
Using an optional BNC cable, connect the INPUT connector of each channel to a signal source. The data signals of channels 17 to 32 can be monitored with the MONI connector of PC216A.
Use the SPEED key and the CH/NEXT key of the PC216A to set the 32-channel mode.
When the 32-channel mode cannot be selected, reconfirm the connection. Refer to section 4-2, since the data-recording procedure is the same as using the PC216A alone.
The PCCX32 is only active for the 32-channel mode playback. Refer to section 4-3, since the data playback procedure is the same as using the PC216A alone.
When a tape which has been recorded in the 32-channel mode is played back using the PC216A without PCCX32, the analog data of 17 to 32 channels cannot be output while the analog data of 1 to 16 channels and the parallel digital data can. And in this case, which channel mode (16-channel or 32-channel) was selected at the recording can be recognized by the following method: 32-channel mode: The channel number between 17 to 32 can be selected and
indicated at the MONI area on the display.
16-channel mode: The above channel number can not be selected and indicated.
With two PC216As in synchronizing mode, the number of channels can be doubled without changing the frequency band. As the slave machine is locked to the master's clock, word-accurate synchronous recording is possible. The recording and playback can also be performed in different channel modes or analog/digital modes according to the setting of the master and slave machines.
The SPEED setting on the slave machine follows the setting on the master machine.
The modes on the slave machine follow ones on the master machine, such as REC, PLAYBACK, FF, REW, E-E, PAUSE and manual search. They are also linked when the machine is externally controlled from the REMOTE connector.
The slave machine can not control the operation of the master unit.
The tape counters (COUNT) of both machines are automatically reset to zero at the each start of recording. The COUNT of the slave machine follows that of the master machine during recording. Thus the data recorded on the master and the slave tapes at the same ADDRESS are exactly synchronized.
The ID number can be preset for the master and the slave machines independently.
The ID increment of both machines can be performed simultaneously by pressing ID key of the master machine.
If the master machine is set to auto ID increment mode (refer to the page 4-3), the ID numbers of the both machine are auto-incremented at each stop of recording.
Except above-mentioned settings, the master and slave machines can be set individually, such as analog/digital mode, B/C mode, Input range, etc.
Although the master and the slave machines run synchronously in FWD mode, the slave machine does not automatically chase the master machine for the same ADDRESS.
However, the data at the same ADDRESS for the both tapes are the data captured at the same sampling time. So "off-line synchronization" is possible by transferring the data from the specific ADDRESS on both the master tape and the slave tape to a host computer.
In the setting for synchronous mode, the indication of the SYN LED varies according to the status of the machines.
Status | MASTER | SLAVE |
---|---|---|
Recording in sync condition | ON | OFF |
All other status other than above | BLINK | OFF |
Erroneous operation* | OFF | OFF |
* Check setting and cabling.
The error code on the LCD display and SYN LED indication will appear if abnormal conditions happen during synchronizing operation.

Communication between the computer and PC216A is performed by transmitting commands from the computer and returning status from the unit in response to the commands. Each unit of both transmission and reply is called a "record". The terminator characters which indicate the end of the records are "CR" (carriage return) and "LF" (line feed).
(The unit acknowledges CR as the record terminator even if LF is missing.) Before setting the commands, check that the unit is in the "receiving possible" condition with the "RDY?" command. The unit returns the "RDY" command when it is ready for receiving. When transmitting the status command, confirmation using with the "RDY?" command is not necessary. All communications are performed using ASCII codes.
The symbols on the command/status display are as follows:
indicates space (blank). (1), (2), (3)... are characters in the command, and indicate 0 to 9 or the ASCII characters of the alphabets. [] indicates PCCX32 only. RSVD indicates reserved.

The PC216A is a data recorder capable of analog data input/output but data is stored on the magnetic tape as a digital (binary) formatted code. The digital formatted code can be output during playback in addition to analog data. This makes data transfer possible (either directly or via the digital data interface unit PCIF11A/PCIF-1) for high-accuracy data analysis.
An LSB channel is provided in addition to the main analog data channels (2, 4, 8, 16, and 32 channels), facilitating the recording/playing back of digital data simultaneously with main-channel analog data.
Also, when the digital mode is selected and the serial digital input/output function (conformed to RS-422A) is available, the PC216A can also be used as a digital data recorder.
The playback of the analog main data signal (2, 4, 8, 16, or 32 channel) can be output in a 16-bit parallel format (main data 15-bit + LSB 1-bit). Data coding is offset binary*.
Data transfer rate is 96 k words/s (normal speed), or 192 k words/s (double speed). Interface output level is TTL.
Use of the least significant bit (LSB) of quantized 16 bits for digital I/O, the LSB channel can be used to record/play back digital signals (i.e. engine rotation pulse, control signal, time code signal, etc.) independently from the main channel analog signals (2, 4, 8, 16, or 32 channel). Although the dynamic range of 80 dB and other analog characteristics are secured as quoted. Both input and output levels are TTL compatible. Sampling frequency is 96 kHz (normal speed) or 192 kHz (double speed).
The serial digital data can be input and output between the PC216A and an external PCM encoder/decoder. The transfer rate is 1.536 Mbps (normal speed) or 3.072 Mbps (double speed) when synchronized, and less than 0.768 Mbps (normal speed) or less than 1.536 Mbps (double speed) when unsynchronized. The input/output level conforms with RS-422A.
* Offset binary
Offset binary is a variation of the 2's complement system, in which the MSB is inverted. In the PC series, 0% data is assigned to 8000H. For more details, see item "DATA" on page 13-5.

Selection between analog mode and digital mode can be made by shorting pin 34 and ground of DIGITAL DATA I/O connector.
With the optional signal splitter PCCB21/21A which has a slide switch, the analog/ digital mode selection can be easily achieved.
When the PC216A is in analog mode, the main data signals on tape are played back and the parallel digital signals are output from the specified terminal of the DIGITAL DATA I/O connector together with the analog data. (See the table on page 13-2.)
When using the Digital Data Interface Unit PCIF11A, the data can be transferred to a host computer at normal speed only, and the PCIF-1 at normal speed and at 2 times speed.

The signals are measured at the point indicated by the arrow in the following recommended external circuit. However, XA4 (Pin 23) only is not inverted.
Fig. 13-5-2. AN EXAMPLE OF CONNECTION TO THE RECOMMENDED EXTERNAL CIRCUIT
Input/output digital signals to the specified pins of the DIGITAL DATA I/O connector (see page 13-2). When the data recorder is in record mode, LSB input signal through the DIGITAL DATA I/O connector is recorded at the same time as the main data signals. When the unit is in playback mode, the LSB signal is output through the DIGITAL DATA I/O connector.
Care should be exercised in the selection of the sampling rate, in order to avoid the distortion inherent in discrete sampling.

By setting the PC216A into Digital Mode, it is possible to record an incoming serial digital signal generated by an external PCM machine (such as a digital telemetry system) where analog signals, typically generated from multiple transducers, are A/D-converted and formatted (encoded and multiplexed). The serial input and output terminals are provided in the DIGITAL DATA I/O connector.
In the Digital Mode the PC216A functions as a transparent storage device, i.e. the played back digital signal is equivalent to the incoming signal to the recorder. Thus, the Digital Mode is well suited to record a digital bit stream which is pre-formatted/ encoded by external PCM equipment.
There are two types of data transfer between the PC216A and external PCM equipment: synchronous mode and asynchronous mode.
In this mode, the incoming digital signal generated by the external PCM equipment must be synchronized by the PC216A and the bit rate must match the bit clock SCLK. The SCLK is provided in the DIGITAL DATA I/O connector to lock the external PCM equipment (PC216A can not be synchronized by an external clock). The incoming digital signal (NRZ) is in sync with the rising edge of the SCLK, and the playback digital signal is generated by clocking the data within the recorder as illustrated in Fig. 13-7-1. In synchronous mode, it is possible to record and play back a digital signal at the maximum bit rate, i.e. 1.536 Mbits/ sec. at the normal speed mode or 3.072 Mbits/sec. at the double speed mode.

In asynchronous mode the bit rate of the external PCM equipment is independent of the clock frequency (SCLK) of the PC216A. In this mode, the data transfer is made without using SCLK. The incoming digital signal (NRZ) is sampled using the SCLK and then recorded. Because of asynchronous sample timing, the length of the sampled data bits of the incoming data will vary. The data can not be correctly reproduced if the amount of fluctuation exceeds one half of the original bit length. In other words, the maximum bit rate must be less than half of the sampling rate, i.e. 0.768 Mbits/sec at the normal speed or 1.536 Mbits/sec at the double speed. Figure 13-7-2 shows an example of timing when the incoming bit rate is more than half of the sampling rate, and Fig. 13-7-3 shows the case when the incoming bit rate is less than half of the sampling rate.
