Rx Level Calculation; Line Error Mark Print - Ricoh C2000 Service Manual

• EQM and rx level are fixed at "FFFF" in tx mode.
• The seventh and eighth numbers are fixed at "00" for transmission records and ECM
reception records.

Rx level calculation

Example: 0000 // 32 V34 // 288/264 // L 01 00 03 04
The four-digit hexadecimal value (N) after "L" indicates the rx level.
The high byte is given first, followed by the low byte. Divide the decimal value of N by -16 to get
the rx level.
In the above example, the decimal value of N (= 0100 [H]) is 256.
So, the actual rx level is 256/-16 = -16 dB

When "1" is selected, a line error mark is printed on the
printout if a line error occurs during reception.
This is a fault-finding aid. The LCD shows the key parameters
(see below). This is normally disabled because it cancels
the CSI display for the user.
Be sure to reset this bit to 0 after testing.
This is only used for communication troubleshooting. It
shows the content of the transmitted facsimile protocol
signals. Always reset this bit to 0 after finishing testing.
If system switch 09 bit 6 is at "1", the list is only printed if
there was an error during the communication.
Do not change the setting.
Comments

With this setting on, the machine resets itself automatically
if a transmission stalls and fails to complete the job.
