The sleep timer feature automatically interrupts program execution if no event takes place

within the specified length of time preset by bit 7 to 0. Shown below are examples of

OUT

statements. Setting 0 to this byte disables the sleep timer feature. (Refer to Chapter 10.)

OUT 6,30 ’3 seconds

OUT 6,0 ’No sleep operation

To activate the wakeup function, set 1 to this bit; to deactivate it, set 0.

To make the TIME$ function return or set the system time, set 0 to this bit; to make the

TIME$ function return or set the wakeup time, set 1.

Execution of the

TIME$ function after selection of the wakeup time will automatically reset

this bit to zero.

The BHT-5000 may display the system status on the bottom line of the LCD. To display the

system status, set 1 to this port; to erase it, set 0. For the system status indication, refer to

Chapter 7, Subsection 7.1.7.

This byte sets the re-read prevention enabled time length in units of 100 ms. Specification

of zero (0) permanently enables the re-read prevention so that the BHT-5000 does not read

same bar codes in succession. The default is 10 (1 second).

*10

An 8-bit binary pattern (bits 7 to 0) on the output ports 10h to 40Fh (which are stored in the

VRAM) represents a basic dot pattern column of the LCD. Bit value 1 means a black dot.

The port number gives the dot column address.

If you send graphic data to the VRAM area (assigned to the bottom line of the LCD) by

using the

OUT statement when the system status is displayed on the LCD, the sent data

will be written into that VRAM area but cannot be displayed on the bottom line of the LCD.

*11

Refer to Appendix H, “[ 3 ] Program file named APLINT.PD3.”

*12

If the backlight function is activated with the OUT statement, the specification by the KEY

statement will be ignored. For details, refer to Chapter 13.

If you set 0 to the ON-duration (6021h), the backlight will not come on; if you set 255, it will

be kept on.

*13

You can set the held-down time of the power key required for powering off the BHT-5000.

The setting range is from 0.1 to 25.5 seconds in increments of 0.1 second. The default is 5

(0.5 second).

*14

You can set the communications protocol type for transmitting files with the XFILE state-

ment. To transmit files between the host computer and more than one BHT-5000 (placed

on the multilinked CU-5003s), set 1 (multilink protocol) to this port. The file transmission by

using the multilink protocol requires also Multilink Transfer Utility (MLTU3.EXE) to be run in

the host computer, Multilink Protocol System (MLTU3.EX3) to be run in the BHT-5000, and

the CU-5003(s).

If Multilink Protocol System (MLTU3.EX3) has not been downloaded to the BHT-5000, the

BHT-protocol will be used instead of the multilink protocol even if this port is set to 1 (multi-

link protocol).

*15

You may set the BHT's ID number to be used for the multilink protocol. The ID number is

expressed by two bytes: lower byte on port 6061h and upper byte on port 6062h. The set-

ting range is from 1 to FFFFh. To set the ID number to 1234h, write as follows:

OUT &h6061h,&h34 ’Sets 34h to the lower byte of the ID

OUT &h6062h,&h12 ’Sets 12h to the upper byte of the ID

1 2 ... 495 496 497 498 499 500 501 502 503 504 505 ... 559 560
