連接通信線路
EIA-232和5伏緩沖電路有一條傳輸線和一條接收線，而EIA-422有兩條傳輸和兩條接收線。表1-2顯示了手持和面板安裝QTERM II的連接器引腳分配。表中顯示的接收和發(fā)送方向與QTERM-II有關(guān)。請(qǐng)參閱此表，將主機(jī)通信線路連接到正確的插針。不要連接dig0和dig1引腳；第2章討論了這些引腳及其用途，顯示了電源線和地線的引腳分配。將直流電源連接到相應(yīng)的兩個(gè)插腳。警告：供應(yīng)給QTERM-II的電源必須來自SELV電源，其輸出電流限制應(yīng)為5安培。如果您未訂購(gòu)調(diào)節(jié)器選件，QTERM-II的電源必須至少提供4.8伏直流電，最大不得超過5.5伏直流電。如果您訂購(gòu)了調(diào)節(jié)器選件，QTERM-II的電源必須至少提供5.5伏直流電，并且最多只能提供24伏直流電。限制可能是電源固有的，也可能由輔助過電流裝置提供。如果您訂購(gòu)了電池備份選項(xiàng)，則無需連接電源；只需在電池盒中安裝六節(jié)堿性AA電池。1.4通信此時(shí)，主機(jī)傳輸?shù)淖址麑@示在QTERM-II顯示器上。如果您按下鍵盤上的鍵，QTERM-II將向主機(jī)傳輸適當(dāng)?shù)拇a。1.5運(yùn)行QDEMO為了方便地使用QTERM-II的一些高級(jí)功能，運(yùn)行本用戶手冊(cè)中包含的QDEMO程序：?將QTERM-II連接到IBM風(fēng)格PC上的COM1或COM2串行端口（如果您有EIA-422或5伏緩沖QTERM-II，則需要提供一個(gè)接口單元，如Beijer Electronics的QCOM-2；您不能將具有這些接口之一的QTERM-2I直接連接到IBM樣式計(jì)算機(jī)上的COM端口?。?br/>
There are only four steps required
to communicate with the QTERM-II: ? use Power-On Setup to set the contrast, baud rate and data format ? connect to your host transmit, receive and ground lines ? apply power ?transmit and receive with the QTERM-II 1.1 Power-On Setup The Power-On Setup procedure is used to configure the QTERM-II's display contrast, baud rate and data format. You use three different QTERM-II keys to do this configuration (see Figure 1-1): Top - Right:this is the up key Top - 2nd from Right:this is the down key Top - 3rd from Right:this is the save key To perform the Power-On Setup follow these steps: ? Hold down any key and apply power to the QTERM-II (you do not need to connect the transmit and receive lines). ?The version of software in the QTERM-II will be displayed as long as you hold down the key, after which the you can adjust the display contrast. ? Set the desired display contrast using the up and down keys. When the display is at a contrast you like, press the save key. ? Set the desired baud rate (see Table 1-1) using the up and down keys. When the desired baud rate is displayed, press the save key. ? Set the desired data format (see Table 1-1) using the up and down keys. When the desired data format is displayed, press the save key. Disconnect power and go to the next step ?Copy the file QDEMO.EXE to your hard disk. ? Apply power to the QTERM-II. ?Run the QDEMO program. ? Follow the on-screen instructions to use many of the features of the QTERM-II terminal. QDEMO will allow you to exercise many of the features of the QTERM-II. It includes a terminal emulator so that you can also communicate directly with the terminal.
Connect the Communications Lines
The EIA-232 and 5-volt Buffered have one transmit and one receive line, while the EIA-422 has two transmit and two receive lines. Table 1-2 shows the connector pin assignments for both the handheld and panel-mount QTERM-IIs. The receive and transmit directions shown in the table are with respect to the QTERM-II. Refer to this table to connect your host communications lines to the correct pins. Do not connect to the dig0 and dig1 pins; Chapter 2 discusses these pins and their uses shows the pin assignments for the power and ground lines. Connect your DC power supply to the appropriate two pins. WARNING: Power supplied to the QTERM-II must be from an SELV power source, and should have a current limit on its output of 5 Amperes. If you did not order the regulator option, the supply to the QTERM-II must provide a minimum of 4.8 volts DC and be limited to a maximum of 5.5 volts DC. If you did order the regulator option, the supply to the QTERM-II must provide a minimum of 5.5 volts DC and be limited to a maximum of 24 volts DC. Limiting may be inherent to the supply, or may be provided by supplementary overcurrent devices.If you ordered the battery back option, you do not need to connect a power supply; just install six alkaline AA batteries in the battery compartment. 1.4 Communicate At this point, characters which are transmitted by the host will be displayed on the QTERM-II display. If you press keys on the keypad, the QTERM-II will transmit the appropriate codes to the host computer. 1.5 Running QDEMO To easily use some of the advanced features of the QTERM-II, run the QDEMO program that is included with this User's Manual: ?Connect your QTERM-II to either the COM1 or COM2 serial port on an IBM-style PC. (If you have an EIA-422 or 5-volt Buffered QTERM-II, you will need to provide an interface unit such as Beijer Electronics' QCOM-2; you cannot directly connect a QTERM-II with one of these interfaces to the COM port on an IBM-style computer!)
