Introduction
The MR350MKII(MR350 Mark II) is an intelligent data collection terminal which provides
many features for sophisticated data collection applications, with good expandability,
flexibility, security and maintainability. Data can be collected in an efficient and accurate
manner through use of a keypad, bar code scanner, magnetic stripe reader, proximity reader,
ICC reader, photo-coupler digital input, and relay digital output. The MR350MKII also
provides an easy and flexible method of wall mounting without additional mechanical
hardware.
The MR350MKII is well suited for the following applications:
??Time and attendance
??Loyalty
??Shop floor control and reporting
??Access control
??Job status and tracking
??Library application
??General data collection
This manual gives you detailed information about the characteristics of hardware
components, an introduction to the MR350MKII system kernel structure, the principle of
communications protocol, operation of supervisor mode, site preparation and installation
and command set summary for I/O function calls, DOS management function calls, File
management function calls and Host ESC commands.
Throughout this manual [X] will be used to represent the key which has legend 'X' on the
keypad. "ABC" will be used to represent the sequence of key-presses for 'A','B',and 'C'. The
MR350MKII system uses the block and underscore cursor to represent if keyboard is in
either numeric or alphabetic mode. Press the [SHIFT] key to toggle numeric and alphabetic
mode. For example, in the block cursor mode, press the [1/QZ.] key to display '1'. In the
underscore cursor mode, press the [1/QZ.] key to display the first character 'Z'.

2.4. Keypad
The MR350MKII provides an insertion template type membrane keypad, user can
re-define layout of keypad and customize user own template. All keys on the keypad
provide a tactile feel. The size for each key is 17mm by 14mm. It contents 20-key
alphanumeric/function membrane keypad with four user controllable indicators and
clock-in/out and break-in/out symbols.
The figures below present layouts for the keypad. To see the function of each key,
please refer to your Getting Started Guide.
Figure 2-3A-type layout
??NOTE: Where the code value of symbols:
are identical to F1 to F7.
2.5. Display
A 2-line by 16-character liquid crystal display(LCD) with 5x7 dot character font and
backlight is used as the display screen of the terminal. The backlight can be enabled
or disabled using either the USER COMMAND “SET” (see Getting Started Guide)

2-11
or the user’s application program (see Programming Reference Manual). If the UPS
battery is installed and the main power (external AC power) fails, in order to reduce
power consumption the MR350MKII will shut off the backlight ignoring the above
setting until the main power is recovered. A blinking block cursor represents
numeric mode, and a underscore cursor indicates that the keypad is in alphabetic
mode.

can serve in multi-point or no protocol for data communication. (for detailed
information please see the MR350MKII Programming Reference Manual). Up
to 32 terminals may be connected to the multi-point communication network
operating on one port at speed up to 57600 bits per second (bps), with 8 data
bits and none parity, or 7 data bits and odd, even or none parity and with 1 stop
bit or 2 stop bits. The maximumcable length of a multi-point network allowed is
up to 4000 feet using a twisted pair network cable.
