Sharp 5700 POS Terminal

Last edited: December 15, 2003 08:17 AM

The Sharp UP-5700 is a PC based computer designed to function as a POS workstation or as a standalone computer. It comes with two serial ports and two cash drawer ports. There are two expansion half-slots for which add-on cards are available to provide a parallel port, floppy disk support, and network capability. Optional accessories include up to two cash drawers and a magnetic stripe reader. Additional accessories are available from Sharp but are not supported at this time by Touch Menus.

Configuration Switches

A bank of 6 switches can be located by opening a small panel located on the left side of the terminal directly behind the brightness adjustment dial. These switches are read at power up and instruct the system how to boot and what drive configuration to use. Switches should be set as follows:

    *      1,2 On – If floppy disk connected. Off otherwise.
    *      3,4 On, 5 Off – If terminal has hard disk.
    *      3,5 On, 4 Off – If terminal has no hard disk.
    *      6 On, 1-5 Off – To configure CMOS on power-up.
    *      All Off – For APLD load on power-up.

CMOS

A 3.6V battery is used to maintain CMOS information. This battery is accessible through a panel located on the bottom of the terminal. If necessary, CMOS can be configured as follows:

  1. Set switch 6 to On, and all other switches to Off.
  2. Power up the workstation.
  3. A message will be displayed telling you when configuration is complete.
  4. Turn power off and return the switch settings to their normal operating position.
  5. Turn on power and let the terminal boot normally.

Drive Structure

The 5700 can come with hard disk, floppy disk, PSRAM (PseudoStaticRAM), MROM (MaskROM), and FROM (FlashROM). Each is assigned a drive letter, depending on the configuration switch settings at power on.

Standard Configuration

    A: – Floppy Disk
    B: – MROM (read only – comes preprogrammed with DOS)
    C: – Hard Disk(contains all files needed by terminal)
    – PSRAM(1MB on motherboard, currently unused)
    E: – FROM(read only, currently unused)

Optional Networked Terminal (w/PSRAM boot – no hard disk)

    A: – Floppy Disk
    B: – MROM (read only – comes preprogrammed with DOS)
    C: – PSRAM (3MB, 1MB motherboard + 2MB addon)
    – FROM (read only, contains some utilities)
    E: – Unused (assigned to hard drive if connected)

Touch

The 5700 uses a resistive touch screen that is accessed with a mouse emulation driver, MEDVSRP.COM, located in the POSSYS directory. There is no calibration program. If the mouse driver cannot access the touch screen, the terminal needs replacing.
Network

An optional network card, the 3COM Etherlink III, can be added using one of the expansion slots. This board is referred to as a 3C509B board. It is accessed using NDIS drivers. See Boot Files for Networked Workstation for the exact drivers needed. The board should be installed using a Base IO Address of 300 and IRQ 5. If necessary, the network card can be configured with the utility 3C5X9CFG which comes on an accessories disk with the network card.
Serial Ports

Two serial ports come standard with the 5700. They are accessible through DOS as Com1 and Com2 using IRQ4 and IRQ3 respectively. Two additional Com ports are available on the A8RS add on card. They are configured as Com3 and Com4 using IRQ11 and IRQ10. All use a DB9 male connector. The serial driver, SIO.SYS is must be loaded to access these ports. It can be found in the POSSYS directory.
PSRAM

The 5700 comes standard with 1MB of PSRAM (pseudostatic random access memory) on the motherboard. An additional 2MB can be added via slots located toward to the right of the microprocessor. If using a hard disk, the PSRAM is not needed. Otherwise, a full 3MB is required to assure that the terminal can perform all workstation functions.
A8RS Add-on Card

The A8RS is a multifunction card containing a floppy disk controller, one parallel ports, and two serial ports. It is required for standalone operation to provide a parallel port for the HASP, and a floppy disk for loading software on to the hard disk. For the networked workstation it is optional.
Styling

Support was added in TouchPro 6.50 for the cash drawers and magnetic stripe reader, through the OEM Instructions command. To activate the OEM subcommands, an environment variable must be set. In the Autoexec.Bat for all Sharp terminals, be sure to put the following:

    SET PLATFORM=5700
