Introduction System Design The LAVA HQ-ST Link consists of ST Plus devices installed at each store. The ST Plus devices communicate with an assigned and dedicated HQ-Plus device at the head office. The ST Plus devices are attached to the cash register(s) in each store, and to the store's Internet connection. Polling software running on a head office computer can poll each cash register, via the HQ Plus. The system is supported by the included ST Plus Configuration Console application, which

Primary Hardware Components of the HQ-ST System The ST Plus and HQ Plus are the two essential hardware components in an HQ-ST Link. ST Plus devices, attached to ECRs in stores, connect to their assigned HQ Plus device located at a head office. ST Plus The ST Plus is a device operates as a TCP/IP Raw Client, with the intention of providing a store-side serial-to-Ethernet interface to an ECR or other similar device. The ST Plus provides a serial port with the I/O characteristics and pin-out of a

Figure 4: ST Plus: rear connections HQ Plus The HQ Plus operates as a TCP/IP Raw Server, with a known IP:Port address. The HQ Plus is intended to provide a head- office serial-to-Etherenet interface for a polling application to access remotely located device to be polled. The HQ Plus provides a modem-like serial interface (US Robotics (USR) command set, DB-25F connector), that is used by an external device such as a PC to make a "telephone - modem" call (that is, using a conventional modem dial

Secondary Hardware Components of the HQ-ST System The HQ Remote Console and HQ Remote Poller provide the capability to locate a parallel "HQ site" which can be readily re-located. The HQ Remote Console and the HQ Remote Poller can be deployed as standalone devices, at the same or at separate sites. Enabling and disabling of the remote devices is controlled from the main HQ Plus through the HQ Basic software control to allow or disallow remote console and remote poller functions accesses. HQ R

Software Components of the HQ-ST Link System While not essential to the main task of polling over IP, the following components supplement the basic HQ-ST Link and and assist installation or are required for device configuration . HQ Basic Software This system management utility, supplied with HQ Plus hardware, provides configuration interfaces for HQ Plus and ST Plus devices, and presents a tabular view of the state of all ST Plus connections current on a given HQ Plus. It also provides rudi

LAVA HQ Plus Install Equipment Needed To set up an HQ Plus for polling you will need: � polling software [not supplied] � LAVA HQ Basic software (See “H Q Basic: Operation” on page 19.) � LAVA HQ Plus with power supply (do not co nfuse power supply with that of ST Plus) � Windows-based PC with 2 available COM ports (2 x DB-9) [not supplied] (two separate computers could also be used for polling software and HQ Basic software if desired) � one Ethernet cable (CAT-5 UTP with RJ-45 connectors) [no

4. Once connected, double-click on the last entry in the table (the entry is named “CONSOLE LOCAL” and denotes the HQ Plus that is currently connected). 5. In the Network Settings screen that appears, enter at least the following: the IP address of this HQ Plus (factory default is 192.168.0.35) and an Identification Key matching that used by ST Plus units targeting this HQ Plus (factory default is a string of zeros). LAVA recommends changing the Identification Key from this factory default to

6. The default values in the Serial Settings tab are for display only and cannot be changed. 7. The serial settings in the “Modem Settings” tab must be set to match those used in the polling generally (that is, those of the ECR, ST Plus, and polling software). Rev.

8. The modem settings on the right hand side of this tab may not need to be changed, depending on the particular modem requirements of the polling software. LAVA suggests starting with them at their default values. 9. Connect the HQ Plus “Modem” port to the PC’s second COM port using the DB-9F to DB-25M serial cable. 10. Connect the HQ Plus’s Ethernet port to the store LAN on which the “Default Gateway” is located. 11. Map a TCP port nnnn (default port number is 4098) on the headquarter’s gatew

Important: The headquarters site requires static IP addresses — the HQ LAN IP address must be static, AND the WAN address of the HQ LAN site device must be static. The WAN/Internet IP address must be a known STATIC IP address (or an assigned DNS name). Use Internet Explorer to access www.whatismyip.com to verify the address. Also verify that this is so by accessing the setup parameters of the gateway/router that is to be used to provide the access to the Internet for the LAN. Note: The HQ sit

7. Attach the PC that will host the polling software. The serial port of the polling host PC should be connected to the “Modem” port of the HQ Plus. In general, it is most trouble-free to configure the serial port of the polling host PC to match the serial port of the HQ Plus, and to ensure that serial settings and connections end-to-end (from polling software to polled device) are consistent. 8. If necessary, troubleshoot the link using the troubleshooting chart: See “Troubleshooting” on pa

6. The Identification Key must match that of the HQ Plus to which you are connecting. 7. Set the correct serial port settings. They should match the settings of the polling software, the ECR's communications port, and the HQ Plus modem port. 8. Connect the Ethernet port of the ST Plus to the store's LAN. Click "Write" and then click “Run” . You should see a time stamp and a “Connected to Unit: [device name]” message in the Message dialog window. 9. Select the mode of ST Plus operation: STOP,

RUN. Enter this mode after the ST Plus is set up, to test if it can open a connection to the designated "call home" IP:port of an HQ Plus. In this mode the ST Plus will connect to the HQ Plus, and remain connected and fully operating, until the ST Plus is reset or power cycled . After a reset or power cycling, the ST Plus will revert to STOP mode. Run mode is typically used for testing the setup configuration or re-configuration, prior to placing the ST Plus into fully operational mode. Acc

ST Configuration Console: Operation The ST Configuration Console provides a Windows-based interface for users to configure the network and serial port settings of an ST Plus device. These settings are required for the operation of the ST Plus in an HQ-ST Link. It also provides an interface for supplying store-specific information for storing in an ST Plus. These details are not used for connectivity, but may be used as contact information or for store identification from the head office. Hardw

At a minimum, you will need to set up the network connectivity, the home IP/port, and the identification key. � LAVA recommends using DHCP at the store, to simplify co nnectivity. If you are configuring the network manually, you wil need to supply the ST Plus with an IP address (IP Address) , a subnet mask (Subnet Mask), and an address for the network’s gateway (Default Gateway). � The “Home IP/Port” settings are the IP addres
