Chapter 8. MVS-<strong>STX</strong> Service Menu<br />

Micro<br />

This menu allows you to clear the user-defined<br />

16-character channel ID, test the keyboard,<br />

print setup information for each channel,<br />

rescan PCB <strong>and</strong> slave device addresses, reset<br />

the nonvolatile RAM to default parameters,<br />

st<strong>and</strong>ardize <strong>STX</strong> PCBs, test <strong>and</strong> view serial<br />

communications, <strong>and</strong> test the nonvolatile<br />

RAM. It has the following submenus:<br />

IDrst (ID reset)<br />

This function resets the user-defined IDs for<br />

all channels. After this function is used, the<br />

top line of the channel monitoring display will<br />

show only the factory-set channel ID number.<br />

KeyT (keyboard test)<br />

This function displays the number of the last<br />

key that was pressed. Table 8-4 lists all the<br />

keys on the MVS keypad <strong>and</strong> their corresponding<br />

reference numbers.<br />

Prnt<br />

This function prints setup information for<br />

every enabled channel. Included are<br />

calibration parameters, linearization<br />

parameters, setpoint parameters, <strong>and</strong><br />

current output parameters.<br />

RScn (rescan)<br />

This function allows the MVS to automatically<br />

rescan all addresses in the system or allows<br />

you to manually rescan <strong>and</strong> modify selected<br />

addresses. RScn has two submenus:<br />

Auto <strong>and</strong> Man.<br />

Auto (auto rescan)<br />

This function allows the MVS to automatically<br />

scan all addresses in the system. Auto has<br />

two submenus:<br />

• All — If the MVS is the Master, the MVS<br />

scans I 2 C <strong>and</strong> the COM1 port. If the MVS<br />

is the Slave, the MVS scans I 2 C but does<br />

not scan the COM1 port.<br />

• i2c_IO — The MVS scans I 2 C but does<br />

not scan the COM1 port.<br />

The microprocessor PCB begins the polling<br />

process with an identify comm<strong>and</strong>, beginning<br />

with address 1 to 7F Hexadecimal in the<br />

internal I 2 C bus. Each PCB (Relay Output,<br />

Current Output, signal processor, etc.) has a<br />

unique coded response. The microprocessor<br />

PCB initializes its nonvolatile memory in<br />

accordance to these responses. Once the<br />

I 2 C polling is done, external addresses<br />

through the COM1 serial port are examined<br />

(if All was selected).<br />

When the MVS arrives from the factory, it is<br />

set up to recognize the addresses of all the<br />

factory-installed PCBs. However, the MVS is<br />

not able to recognize any slave devices you<br />

connect to the serial port. Additionally, if you<br />

add PCBs (Relay Output, Current Output,<br />

signal processor, etc.) to the MVS, the MVS<br />

is not able to recognize those new PCBs.<br />

Follow this procedure to enable the MVS to<br />

recognize slave devices <strong>and</strong> new PCBs:<br />

1. If in Auto Mode (Auto LED illuminated),<br />

press the Auto/Man Key to put the MVS<br />

in Manual Mode. The Auto LED turns off.<br />

2. Press the Menu Key to display the Main<br />
