SELECTING UPDATE DATA TO	1-BYTE MEMORY CHANNEL NUMBER
DOWNLOAD	DATA STRUCTURE

As mentioned before, there are four opcodes that cause the MARK-VFT-1000MPto report (update) its operating status by downloading all or a portion of its 1,863 data bytes. These opcodes are shaded in the CAT Commands table (pages 94 ~ 97).

Status Update (Opcode 10H) - The 1st and 4th parameters of this command allow selecting different portions of Status data to be returned, as follows (“X” is the 1st parameter, “U” is the 4th):

Read Flags (Opcode FAH) -This command can be set to retrieve all six Status Flag bytes, or else five bytes

-three Status Flag Bytes, plus two transceiver ID bytes. The Status Flag Bytes are described on the preceding page, and in the Record Tables on the previous page.

The transceiver ID bytes are used in programs to distinguish the MARK-VFT-1000MPfrom other mod- els, which have different, unique values returned in this situation. The constant values of 03H and 93H are re- turned by the MARK-VFT-1000MP(and only the MARK-VFT-1000MP), as shown:

Flag Byte	Flag Byte	Flag Byte	ID Byte 1	ID Byte 2
1	2	3	(03H)	(93H)

Read Meter Data (Opcode F7H) - Sending this com- mand returns a digitized meter deflection indication, between 00 and FFH (usually around F0H maximum). Four copies of this value are returned, along with one padding byte (F7H), as follows:

Meter	Meter	Meter	Meter	F7H
Byte	Byte	Byte	Byte

During reception, the signal strength deflection is returned. During transmission, the parameter repre- sented by the reading returned depends on the setting of the METER switch.

This identifies the current or last-selected memory channel 1 ~ 99, P1 ~ P5 or QMB 1 ~ 5 for operation. The table below translates hexadecimal codes into corresponding memory channel numbers. Please read the note in the box at the page bottom.

Important Note!

The Hex Memory Channel Codes for returned memory data shown above (Byte 7) are different than those used in upload command data (opcodes)!

The memory channel hex codes used as argument (parameter) bytes for opcodes are offset by one (that is, one value greater) from their returned data counterparts. Therefore the channel hex codes used in opcodes 02H, 03H, and 0DH would range from 01H ~ 71H.

When constructing command block bytes, ensure that the correct memory channel hex code is used!
