Introduction Keyboard Wedge Mode As a keyboard wedge interface, the PSC scanner can be used with ter- minals provided by most of the major terminal manufacturers. In most cases, the PSC scanner is easily connected between the key- board and display of the terminal. The use of Preamble/Postamble, embedded keyboard function codes or keyboard function records allow operation of the terminal without manual entry from the key- board. In this mode of operations, the PSC scanner draws power from th

Unpacking Your package should include a scanner, interface cable, User’s Man- ual, and a plastic scanner holder. The unit should be inspected immediately upon receipt to determine if any damage has occurred during shipment. If damage has occurred, a claim should be filed with the carrier immediately. Retain the shipping box, since it should be used to return the scanner to the factory for service. Installation Keyboard Wedge In Keyboard Wedge mode the PSC scanner simulates keyboard key- stro

Connecting the Power Supply If supplied, plug the connector from the external power supply into the receptacle located on the housing connector. Then plug the power supply into a power source. Connecting a Magnetic Stripe Reader If a detached Magnetic Stripe Reader (MSR) is to be used, plug the connector into the MSR receptacle located on the housing connector. Terminal Power-Up Sequence Turn on the power to the terminal to which the PSC scanner is con- nected. The unit will issue a series of

Serial Communications The PSC scanner provides the user with two different serial commu- nications options: Serial TTL and Serial RS232 communications. Serial TTL Mode Serial TTL is a serial communications interface that uses TTL/CMOS voltage levels ranging from 0 to 5 volts. The user can select a nor- mally high (default setting) or normally low (inverted) voltage levels. Serial TTL communications mode uses different cables than those used in keyboard wedge applications. To configure the PS

® AutoSense Operation ® AutoSense is a factory installed feature requested at time of order. It ® provides for hands-free or handheld operation. AutoSense is acti- ® vated by scanning the Enable AutoSense symbol. The scanner will respond by emitting a continuous, low level red beam of light known ® as the trigger beam. AutoSense is deactivated by scanning the Dis- ® able AutoSense symbol. ® ® When the AutoSense feature is used with PSC’s AutoSense stand (specifically designed for standard an

® NO Enable AutoSense ® NN Disable AutoSense To use this mode of operation properly, the user must first attach the plastic scanner holder to the bracket of the stand as shown in ® Figure 1. The (NO) Enable AutoSense programming symbol is scanned until the green “Good Decode” light blinks. This will acti- vate the trigger screen. The scanner is then placed into the holder and the user must check that the red laser beam is aimed at the reflective ® label affixed to the stand. The AutoSense i

Wand Emulation Operation To operate the PSC scanner in Wand Emulation the user must first turn off the powerto the host device and then detach the scanner from the host device by removing the cable from the scanner. The proper Wand Emulation cable must be connected between the scanner and the portable data terminal for remote data collection. If using an optional Smart Cable, the scanner automatically switches to Wand Emulation. Specific Wand Emulation parameters may still need to be set.

Setup Overview General setup parameters are divided into Keyboard Wedge options (communication to host through the terminal keyboard), Wand Emu- lation options (communication between the scanner and the host sys- tem’s decoder), and Serial Communication options (communications direct to the host system). Default options are denoted throughout the manual as follows: — Keyboard Wedge @ — Wand Emulation # — Serial Communication * Wedge Mode Options Several wedge mode options are available.

Parameters Selection Guidelines Three basic steps must be followed when selecting parameters for your scanner. 1. Review this manual to be sure you understand the terminology. 2. Review the requirements of your host system, with a techni- cal expert from your company, if necessary. This will enable you to determine if any of the factory default settings must be altered. 3. Enable or disable the relevant parameters by scanning the appropriate menus. This operation is described in more detai

1. Scan the bar code beside Intercharacter Delay = XX and lis- ten for one short-high beep. 2. After the beep, scan the bar code beside 0 on the Digit Selec- tion page and listen for one short-high beep. 3. Still at the Digit Selection page, scan the bar code for 5 (the last argument in the command) and listen for two short beeps. Your PSC scanner does not have a distinct programming mode. Instead, it automatically recognizes and reacts to the labels you scan. If, for example, you scan INT

Serial Communication Reset Default To program the communication mode for serial asynchronous com- munication, scan the following label: CA Select Serial Output Baud Rate There are seven standard serial communication baud rates to select from. Your scanner and the serial host computer must be set to the same baud rate. Select the correct rate. DA Baud Rate = 300 Baud DB Baud Rate = 600 Baud DC Baud Rate = 1200 Baud DD Baud Rate = 2400 Baud DE Baud Rate = 4800 Baud DF Baud Rate = 9600 Baud *

Data Transmission Serial transmission data is composed of three of four different ele- ments, depending upon host system requirements. These elements are the START bit, DATA bits (7 or 8 bits), OPTIONAL PARITY bits, and STOP bit (s) (1 or 2 bits). The PARITY bit is used for error detection (e.g., data altered in trans- mission), but is not required by all systems. A parity bit, if required, will be in one of the following four formats: If your system requires a WORD length of 7 bits, one or
