Bit Switches

4.3 BIT SWITCHES
Do not adjust a bit switch or use a setting that is described as "Not used", as this
may cause the machine to malfunction or to operate in a manner that is not
accepted by local regulations. Such bits are for use only in other areas, such as
Japan.
Default settings for bit switches are not listed in this manual. Refer to the System
Parameter List printed by the machine.

4.3.1 SYSTEM SWITCHES

System Switch 00 [SP No. 1-101-001]
No FUNCTION
Dedicated transmission
0 parameter programming
0: Disabled, 1: Enabled
1 Not used
Technical data printout on the
Journal
0: Disabled
1: Enabled
e.g. 0000 (1) // 32 (2) V34 (3) // 288 (4) // 264 (5) // L0100 (6) 03 (7) 04 (8)
(1): EQM value (Line quality data). A larger number means more errors.
(2): Symbol rate (V.34 only)
(3): Final modem type used
(4): Starting data rate (for example, 288 means 28.8 kbps)
(5): Final data rate
(6): Rx revel (refer to the note after this table for how to read the rx level)
2
(7): Total number of error lines that occurred during non-ECM reception.
(8): Total number of burst error lines that occurred during non-ECM reception.
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.
