1.3 General Information

1. If the text is discussing a function key, the function key will be displayed as Fx-

YYYYY

with the programmed user key function in italics. F1 and F2 can both be

programmed to all available user functions.

2. If a function key does not work, it is probably because the Dyna-Link 2 is not setup to support the key. For example, if the Function key is set for TOTAL, you must also setup the TOTAL mode in the setup menu.

3. When in setup menus, the ZERO key drops back one menu level. At the root menu level, the ZERO key stores the changes and returns to the tension mode.

4. When in setup menus, the POWER key returns you directly to the tension display without storing the changes.

1.4 MSI-7300 Annunciators

The Dyna-Link 2 uses LCD annunciators to indicate tension mode and other information.

Figure 1-3. MSI7300 Annunciators

Stable – indicates the tension force has settled within the motion window (usually ±1d). When standstill is off, the link will not zero, tare, or totalize.

Center-of-Zero – Indicates the ten

sion is within 1/4 d of zero.

Low Battery – Appears when approximately 10% of battery life remains. The BT symbol blinks when automatic shutdown is imminent.

PEAK- Indicates peak hold mode.

Ttl

TOTAL – Indicates the unit is displaying the total accumulated weight. This is a temporary display lasting less than five seconds.

Net

NET – Indicates the unit is in the net tension mode. A tare weight is subtracted from the gross tension.

Metric Ton – In conjunction with the ton annunciator, indicates the unit is displaying metric tons. When used with the total display, it is used for X1000 to allow accumulation of weight beyond the five digit display capacity. It is also used with the service counters when the number of lifts exceeds five digits.

kg – Indicates tension display is in kilograms.

kN – Indicates the tension display is in kilonewtons.

lb – Indicates tension display is in pounds.

Ton

Ton – Illuminated alone, indicates the unit is displaying in US short tons (1 ton = 2000 lb). When illuminated along with the ‘M’ the unit is displaying in metric tons (1 metric ton = 1000 kg)

SETPOINTS – User programmable setpoints for early overload warnings. Setpoints 1 and 2 are high brightness red LEDs

F1 F2 – These blue LEDs are used to indicate various operational features of functions programmed into the F1 and F2 keys. Example: In peak hold mode the associated LED will blink whenever a new peak reading is captured.

WARNING

Note

It is not necessary or desirable to tighten the nut too tight. Make sure the nut is down far enough to expose the cotter pin hole.

4. Lock the shackle pin in place with the supplied cotter pin. Bend the cotter pin.

5. Repeat steps 1-3 for the bottom shackle.

6. Remove the battery access port

cover with a coin or a large screwdriver.

7. Insert the two batteries, positive end first, into the battery shaft.

8. Reinstall the battery access port cover. The Dyn

a-Link 2 is now ready for use.

The Dyna-Link2 will automatically start when the batteries are installed.

The Dyna-Link 2 load train will be unsafe for use i

f the shackle pins

are not properly secured with cotter pins.

Introduction 11

1.10 Battery Replacement

Disposable Batteries

The BT annunciator will display when the is battery is beginning to get low. When the BT annunciator starts to blink, the batteries are close to being completely drained. For maximum life, use the batteries until the system shuts off.

Rechargeable Batteries

When using Nickle-Metal-Hydrid

e (NiMH) Cells, it is recommended that the cells are recharged immediately after the BT annunciator starts to blink. Do not allow the batteries to discharge completely, it may compromise the recharge life of the battery.

NiMH Cells in C and D sizes have a lower

capacity then the Alkaline C and D sizes. MSI recommends having two sets of NiMH batteries, so one set can be charging while the other is in use.

Note

NiMH ‘D’ cells are often repackaged ‘C’ cells so you don’t get an increase in battery life for Dyna-Links large enough for ‘D’ cells.

The use of NiCad batteries is not

recommended.

If the Dyna-Link 2 will not be used for an extended period, the batteries should be removed. A small current is used when powered off which will discharge the batteries in about six months.

12 MSI-7300 Operator’s Manual

2.0 Operation

2.1 Power

To turn on the Power

1. Press

POWER

• The LCD will show all segments for a display test.

• The software version number will display.

The D

yna-Link 2 is ready for use.

2.2 Zero

Takes out small deviations in zero when the Dyna-Link 2 is unloaded. See Section 3.6 for zeroing (Taring) package or pallet weights.

Note

The tension reading must be stable within the motion window for the zero function to work.

1. Press

ZERO

. The display reads 0 (or 0.0 or 0.00, etc).

The backup memory stores the zero reading, and can restore it even if power fails.

Zero - Rules for Use:

• Works in GROSS mode or NET mode. Zeroing while in NET mode will zero the gross tension causing the display to show the negative tare value.

• The unit must be stable within the motion window, it will not zero until the stable ann

unciator is on.

• The unit will “remember” that it has a zero

request for two seconds. If motion

clears in that time, it will zero.

• The unit will accept a zero setting over the full range of the Dyna-Link. Zero setti

ngs above 4% of full Dyna-Link will subtract from the overall capacity. For example, if you zero out 100 lb on a 1000 lb Dyna-Link, the overall capacity will reduce to 900 lb plus the allowed over-range amount.

User Key Functions (F1and F2) 13

3.0 User Key Functions (F1and F2)

There are optional functions that can be programmed for the function keys (F1 and

F2) on the front panel, as well as on the RF remote display. See Section 4.2 for setup

instructions.

Note

The functions PRINT (F3), and TARE are available full time on the RF remote display.

3.1 OFF

No USER key function assigned. The F-Key is disabled.

3.2 TEST

The TEST function provides an LCD test that lights all LCD segments and the LED at once and then counts from 00000 to 99999. Other internal tests are performed and if any test fails, an error code will display. See Section 7.2 for a description of all error codes.

3.3 TOTAL

Note

The Total Mode must be programmed from the setup menus before the USER key will function. See Section 4.5.

For accumulation of multiple weighments. The accumulator always uses the displayed weight, so GROSS and NET readings can be added into the same

TOTAL.

There are four modes of totalizing: manual and

three auto modes.

The manual mode requires the

TOTAL key be pressed with the tension on the unit. The

tension will then be added to the previously accumulated value. This assures that a weight on the scale is only added to the total once. Both the manual and three auto total modes require that the tension on the Dyna-Link return below 0.5% (relative to full scale) of GROSS ZERO or NET ZERO before the next weighment can be added. Applied weight must be ≥1% of full scale above GROSS ZERO or NET ZERO before it can be totaled.

3.3.1 MANUAL TOTAL

The Fx-TOTAL key under the MANUAL TOTAL mode functions in this manner:

1. With the tension at more than 1% of capacity, push the

Fx-TOTAL key to add the

current tension to the TOTAL weight. The

Fx LED blinks to indicate the tension

value was accepted. The TOTAL LCD annunciator and the total weight is displayed for about five seconds, then the number of samples is displayed for about two seconds.

2. Remove the weight, when the tension is les

s than 1% of capacity, place next

load to be accumulated on the unit.

3. Repeat until all loads to be accumulate

d have been added to the total.

4. To view the total weight accumulated, push the

Fx-TOTAL key with the tension

at less than 1% of capacity (no weight on unit), the total weight will display for five seconds (view total) without changing the total value. The TOTAL LCD annunciator and the total weight is displayed for about five seconds and then the number of samples is displayed for about two seconds.

The Fx-TOTAL key under the AUTO TOTAL mode functions as auto total on/auto total off:

The auto mode has three variations which are programmed in the setup menu:

• AutoLoad – Any settled tension above the ‘rise above’ threshold will be automatically totaled. Then the Dyna-Link must fall below the ‘drop below’ threshold before another total is allowed.

• AutoNorm – This mode takes the last settled weight to auto total with. The total occurs only once the scale goes below the threshold. This allows the load to be adjusted without a total occurring. Once the load is removed, the scale uses the last settled reading for total.

• AutoHigh – Similar to the AutoNorm mode except the scale uses the highest settled reading. Useful for loads that can’t be removed all at once.

3.4 Clear Total

The Fx-VIEW TOTAL key activates the total weight display followed by the number of samples. While the display is showing the total, total is cleared by pressing ZERO.

3.5 Net / Gross

Switches the display between net and gross modes. Net tension is defined as gross tension minus a tare weight.

To switch between net mode and gross mode:

1. Press the Fx-NetGross key (setup to the net/gross function).

2. The Fx-NetGross key will only function if a tare value has been established.

3. Switching back to gross mode from net mode will not clear the tare value. This

allows the operator to use the gross mode temporarily without having to reestablish the tare value. Only clearing the tare or setting a new tare will change the tare value held before switching into gross mode.

3.6 TARE

In force measurement applications, tare is useful as a way to display differential force. By taring out a known force, only positive and negative deviations from the tared force are displayed. This can also increase accuracy as any initial error is removed leaving only slope error. In scale applications, tare is typically used to zero out a known weight such as rigging, a packing container, or pallet and display the load in

NET tension/weight. To use tare, one of the two function keys must be configured to

the

TARE function. A tare value is entered by pressing the Fx-TARE key. The TARE

function in the Dyna-Link 2 is defined as a tare-in/tare-out operation. The first press of the

Fx-TARE key stores the current tension/weight as a tare value and then the

Dyna-Link subtracts the tare value from the gross tension and changes the display to

NET mode. The next press of the Fx-TARE key will clear the tare value and revert the

display to

GROSS mode. The optional RF remote display has a TA R E key

permanently available.

User Key Functions (F1and F2) 15

3.6.1 To Tare and Display the Net Tension

1. Press (programmed as TA RE ).

2. The tension reading must be stable within the motion window for the tare

nction to work.

3. The digits display 0 and the tension mode changes to

NET.

4. The backup memory in the Dyn

a-Link 2 stores the tare reading, and can restore

it even if power fails.

3.6.2 To Clear the Tare and Revert to Gross Tension

1. Press (programmed as TA RE ).

2. The

NET annunciator will turn off.

3. Absence of the

NET annunciator is the only indication that you are in GROSS

tension mode.

Note

To view the

GROSS

tension without clearing the tare value, program

the remaining function key to the function NET/GROSS.

3.6.3 Tare- Rules for Use:

1. Only positive gross tension readings can be tared.

2. The stable annunciator must be on. The tension/force reading must be stable.

3. Setting or changing the tare has no effect on the gross zero setting.

4. Taring will reduce the apparent over range

of the Dyna-Link. For example, taring 100 pounds of rigging on a 1000 lb Dyna-Link, the Dyna-Link will overload at a net tension of 900 lb (1000-100) plus any additional allowed overload (usually ~4% or 9d).

5. The Dyna-Link stores the tare value in non-volatile memory is restored when power is

cycled.

3.7 PEAK HOLD

Peak hold will only update the display when a higher peak tension reading is established. The peak hold function uses a high speed mode of the A/D converter allowing it to capture transient tensions at a far higher rate than typical dynamometers.

Peak hold is cleared and re enabled with the Fx-Pea

k Hold key. When a new peak is detected, the Fx LED will flash three times. The accuracy of the system in peak hold mode is slightly reduced to .2% of capacity ± 5d. The filter setting is turned off while in peak hold mode to ensure the fastest acquisition rate.

Example Peak Hold Application

The peak hold function is useful in materials and ‘Fall’ tests. Common tests for fiber ro

pe include overall breaking strain (OB€), breaking force, and cycled breaking strain. The Dyna-Link 2 combined with a force test stand, meets the speed and accuracy requirements to properly conduct these tests.

1) Program a function key to Peak Hold (P-Hld)

In this example we’ll use F1 for Peak Hold.

2) Prepare the test stand and test sample.

3) Press ZERO to zero out any residual strain on the link.

4) Press F1 PkHold . Conﬁrm that the “Pk” annunciator is on.

A small jump in the reading may occur depending on the stability of your test stand.

5) Apply the test force. The F1 LED will blink three times for every new peak it detects.

6) When the test force is removed, the Peak value can be recorded.

7) To run a new test, press F1 PkHold to clear the peak value. Conﬁrm the “Pk” annunciator is off. Then repeat steps 3-6.

User Key Functions (F1and F2) 17

3.9 HI-RES

Set a function key (Fx) to Hi-Res, see Section 4.0. Press the Fx key programmed to display the high resolution mode (see Table 1-2 on

page 8). The display will stay in high resolution mode until the selected Fx key is pressed again, or power is cycled. While in the hi-res mode the appropriate Fx LED will blink continuously at a slow rate.

Hi-res mode does not increase the accuracy, but allows for smaller weight increments to be displayed.

Use Tare or the ZERO key to zero out any initial error. Hi-res mode will make the Dyna-Link 2 more sensitive to motion and movement resulting in a less stable display. When hi-res is on, the filter is automatically set to the Hi-1 setting (if Hi-2 is already set, then the filter is not changed). This will have a small effect on settling time. When hi-res is turned off, the filter setting resets to the previous filter setting.

3.10 PRINT

Set a function key (Fx) to Print, see Section 4.0. Pressing the Fx key outputs a configured text string to the RS-232 port on the base of

the unit. If an F-Key is programmed as print and the print setup is configured as continuous,

then the

Fx key is used for start print/stop print. See Section 6.2 for more details on

data output. The print function is always available on the optional RF remote display, so it is not

necessary to program an F-Key to “print” if you intend to trigger print outputs from the remote.

However, if you program F1 or F2 to “print” then pushing F1 or F2 on the Dyna-Link will cause the comm port on the remote to output the selected data string.

If the RF remote display option is installed, the Dyna-Link cannot use its built in comm port except for hard-wire connections to the RF remote display or firmware updates.

5.0 Calibration

The Dyna-Link 2 is calibrated using standard precision test weights. It is required that the weight used is at least 10% of full capacity in order to achieve rated accuracy. For example, use at least a 500kg test weight to calibrate a 5000kg capacity unit. The Dyna-Link 2 supports load cell linearization with up to four span points that can be calibrated in any order. Usually only one cal span point is necessary and is sufficient to reach rated accuracy.

When adequate test weights are not available,

the Dyna-Link 2 can be calibrated using a constant calibration which is referred to as C-Cal. To use C-Cal, a factory generated C-Cal number must be known. MSI supplies original and replacement load cells for the Dyna-Link 2 with the C-Cal value stamped on the serial number label.

There are three aspects of calibration:

• Standard calibration - used for maintenance and routine calibration.

• Initial calibration - used to setup both the capacity and resolution (d) of the DynaLink

. It differs from standard calibration only in the initial steps. Initial calibration is performed after a calibration reset which completely erases the calibration and setup memory.

• C-Cal - If C-Cal values are known, the Dyna-Link can be calibrated without weig

hts.

5.1 Calibration Menu

The calibration menu contains three items: Cal, C-Cal, and auto zero maintenance. The following procedures start with entering into the Cal menu, or for an initial calibration, resetting the Dyna-Link 2 and then going to the Cal menu.

5.3 Guidelines for Capacity and Resolution

Dyna-Links are subject to forces that static scales do not experience. Many bridge cranes, hoist cranes, and mobile cranes lack rigidity and tend to bounce or swing when loads are lifted. For this reason, MSI recommends that resolution is kept in the 1:2000 to 1:3000 range. Some improvement in stability can be achieved by increasing the filtering. However, you should never program resolution that is far greater than you need. If the MSI-7300 Dyna-Link 2 display is never stable, it is recommended that the resolution is reduced as well as filtering increased. In any circumstance, the resolution should never be set higher than 1:15000 due to temperature and noise considerations common to all strain gage based load cells.

The tension must be stable for certain features to work: ZERO tensi

on must be stable to be zeroed. TARE tension must be stable to be tared. TOTAL tension must be stable to be added to the total registers. One way to improve the stability is to increase the filtering, at the risk of increasing settling time. The other is to increase the ‘d’ (reduce resolution). The third way is to increase the motion window. The MSI-7300 Dyna- Link 2 defaults to ±1d as a motion window. It can be changed at MSI to a higher value if desired. Often ±3d is chosen for bridge cranes as these tend to have a lot of bounce to them. This of course carries an accuracy penalty adding ±3 d to the total accuracy of the Dyna-Link if the zero or tare operation happens to capture the tension in a valley or peak.

Setting capacity is dictated primarily by the

capability of the load cell. MSI supplies the MSI-7300 Dyna-Link 2 in many capacities. Never set the capacity of the Dyna- Link higher than the rating of the load cell. Due to the excellent linearity of the MSI Link load cell, it is acceptable to set lower capacities to better match the crane the MSI-7300 Dyna-Link 2 is used on. For example, if the hoist is rated for 9000lb, you can use a 10000 lb capacity Dyna-Link and reset the capacity to 9000 lb so that the Dyna-Link will indicate overload at 9000 lb instead of 100000 lb. Derating as much as 50% of the capacity is usually acceptable, but the Dyna-Link may be less stable if the ‘d’ is decreased (resolution increased).

Note

The capacity of all the MSI-7300 systems is rated approximately 20% higher than the rated capacity in pounds. This is to allow the kg capacity to be exactly 1/2 the number of the pounds capacity.

32 MSI-7300 Operator’s Manual

5.4 C-Cal Calibration

When adequate test weights are not available, the MSI-7300 Dyna-Link 2 can be calibrated using a cal number calibration which is referred to as C-Cal. To use C-Cal, a factory generated C-Cal number must be known. MSI supplies replacement load cells for the MSI-7300 Dyna-Link 2 with the C-Cal value stamped on the serial number label. When a calibration is preformed with test weights, a new C-Cal is generated.

Important

The C-Cal number must be known prior to starting this procedure. For a MSI-7300 with its original load cell, MSI prints this number on the Calibration Record, the serial number tag. CCalibration reduces slightly the absolute accuracy of the system and is intended for non-critical use only. For highest accuracy, calibrate the MSI-7300 with precision test weights.

5.5 Auto Zero Maintenance (AZM)

The Dyna-Link 2 employs an auto zeroing maintenance mechanism to adjust the zero reading to the center-of-zero (COZ). COZ is defined as the tension reading is within ¼’d’ of zero. AZM continuously adjusts zero to maintain COZ. It is recommended that AZM is on to maintain the highest accuracy. However, there are circumstances when it should be turned off. This can happen when minor variations of tension occur while picking up Dyna-Link attachments and the variations fall within the AZM capture window. The AZM capture window (usually 1 ‘d’) and capture time (usually eight seconds) can be adjusted by MSI to meet custom requirements.

5.6 Service Counters

The MSI-7300 maintains two service counters for safety.

• The first counter counts the number of times the scale has been overloaded.

• The second counter counts lifts above 25% of capacity.

These counters serve to warn the user to in

spect the load train after a number of overloads, also when there is a chance of fatigue failure. The power up routine will be interrupted when the lift counter exceeds 16383 lifts or the overload counter exceeds 1023 overloads. If the screen displays LFCnt when unit is powered on :

1. Push TARE to display the 25% lift counter.

2. Push TARE again to see the overload lift counter.

3. Push the ZERO key to acknowledge the warning and return to standard scale operatio

Note

The power up warning message won't appear again for another 16383 lifts ( or 1023 overloads).

1) Program a user function key to be TEST (see function key setup) For this example, F1is programmed as TEST.

2) Press F1- TEST .

3) Within two seconds of pressing the

F1– TEST key, press F1 again

(must be F1 regardless of which key is

programmed as TEST).

The test will sequence through steps 4 to 7 automatically unless you stop it by

pressing F2 immediately, then using

F1 and F2 each parameter can be

observed statically.

4) The display ﬂashes LFCnt (for lift counter) followed by the number of times the weight has exceeded 25% of capacity.

5) Next, the display ﬂashes OLCnt (for overload counter) followed by the number of times the weight has exceeded capacity.

6) Next,the display ﬂashes the CCal value.

7) The Dyna-Link returns to standard weighing mode. If you interrupted the auto sequence,

press ZERO to return to tension link mode.

6.0 Communication Setup

The Dyna-Link 2 can communicate with peripheral devices using RS-232 or 802.15.4 wireless. Only one communications type can exist at a time. The RS-232 port located on the bottom side of the Dyna-Link 2 is useful for setup and calibration using a computer and MSI’s SCCMP Software (SCCMP operation is detailed in the SCCMP User Guide).

6.1 RF Option

Since the RF options are easily connected they are commonly used for gathering weight data after the initial setup of the unit. For RF operation, the Dyna-Link 2 uses an 802.15.4 transceiver to communicate with the MSI-8000 RF Remote Display.

802.15.4 wireless:

• operates in the 2.4GHz ISM band and does not require the end user to obtain a licens

• can coexist with other 2.4GHz systems if caution is

taken to isolate antennas at

least 10 feet or 3 meters from the Crane Scales and MSI-8000 equipment.

MSI-8000

based RF systems are peer to peer. However, for multiple scale

connections, the MSI-8000 acts as the network coordinator.

6.2 Printer Setup

The RS-232 comm port is capable of outputing tension data. All the weight modes the Dyna-Link can measure are available in user formatted form. The control mode program is what causes the Dyna-Link 2 to print.

• USER – the assigned F-Key is pressed, then one transmission of the selected stri

ng type is output.

• On Load – when the tension on the link is stable, one transmission will output, then

the tension must return to zero to enable another print to output.

• Continuous – program the interval in seconds up to 65,535 seconds.

Setting the interval to 0 will set an interval as fast as the system can go. To disable pri

nting, simply don’t program an F-Key to print and set the control to “USER” or

turn the control mode to “OFF.”

6.4 802.15.4 RF Network Setup

When equipped with the 802.15.4 option, the Dyna-Link 2 can connect with an  MSI-8000 Remote Display or

an 802.15.4 modem. The unit uses three numbers to

connect to an 802.15.4 piconet:

1. ScaleCore ID – uniquely identifies each ScaleCore device in a

piconet. It has a

range of 0-254 and must not be duplicated within the same RF channel. For the

MSI-8000 as network coordinator, MSI recommends a number for the DynaLink 2 from 0-3 if multiple units will be connected to the MSI-8000. If a single Dyna-Link 2 is all that’s needed than any number up to 254 is acceptable.

2. RF Channel – establishes the base network, all in

terconnected devices must

match. This number must be in the range of 12-23.

3. Network ID – this is a 64-bit number that all interconnected devices must match. The Dyna-Link 2 li

mits this number to a max of 5 digits for a range of 0 - 99999. Do not use a small number here to help avoid other 802.15.4 networks that default to a network ID of 0.

4. RF Strength – Transmission strength can be set from 0 to 4, default is 1. The settin

gs effect the transmission range with zero is lowest power level and four is the highest. Power 4 will use the battery life quicker, so use the lowest number possible for reliable transmission. If maximum range is needed set the strength to four.

7.4 Firmware Update Procedure

Updating firmware in the MSI-7300 requires the following: a DCE serial cable (MSI 503363-001, or build per DCE cable schematic on page 22), a PC with a terminal program (“Teraterm Pro” recommended), and if the PC does not have standard RS-232 serial ports, then a USB to serial converter. Make sure the driver for the USB converter is properly installed, and that the terminal program is set up for the proper comm port.

The latest firmware code is available from the MSI service department and can be emailed on request. Your firmware version is displayed when the MSI-7300 is turned on in the form of “01-04” (your version will vary). Most firmware updates do not require a recallibration. Consult the version release notes for confirmation.

1. Setup the terminal serial port to 8 data bits, no parity, 1 stop bit, 9600 BAUD, XON/ XOFF (flow control).

2. Connect to the Dyna-Link serial port using the DCE cable. Connect the D9 connector to your PC or USB adapter.

3. (Optional) Test that you have a connection by typing {00FF01?}. If the connection is good the Dyna-Link will respond with {000001r2;0;01E02;2011-07-08;11:05} or something similar.

4. On the terminal keyboard, type {ff0009=0199}

5. Change the terminal serial port to 38400 BAUD. Hit the ‘q’ key to refresh the display. Cycle Power on MSI-7300 by removing and reinstalling batteries. The following menu should appear

(u) Download and program application code (q) query app code info (g) execute app code (r) refresh

Your bootloader version may vary.

6. Type u

Terminal should display:

Send File NOW, or press ^ to abort:

7. Send the .prg file using the file send feature of your terminal program. The character “#” will tick away as the ScaleCore programs.

Send File NOW, or press ^to abort:##################################### ################################################################## ################################################################## ################################################################## ###########################################################

Completed

Note

Appendix 51

8. After the file is received, terminal should display “Completed.” Then the boot menu appears again.

(u) Download and program application code (q) query app code info (g) execute app code (r) refresh

9. Optional step: send q to check the program. The ScaleCore will respond with a message that details the 32b checksum, the product ID and version, and the

application code version number in the following form:

Computed Signature BOB742D Received Signature BOB742D Product ID 07 Dyna-Link product family Product Version ID 00 Optional features code App Code Version 01-04 Firmware version number

If the CRC Signature does not match, go back to step 4 and try again.

10.Send an “r” to restore the boot menu.

(u) Download and program application code

(your bootloader version may vary) (q) query app code info (g) execute app code (r) refresh

11.Send a “g.” The MSI-7300 should start.

32b CRC must match
