Connecting to the Computer

After mounting your PayClock on the wall, you need to connect it to your computer. You can connect the PayClock terminal to the computer using an RS-232 cable or RS-485 cable. Choose the setup that best suits your needs.

Connecting the PayClock via RS-232

1.Turn the PayClock so its back faces you

2.Plug the power cord (AC adapter) into the PayClock, keeping the cord slack

3.Plug the other end of the power cord into a wall outlet

4.Connect the jack end of the serial cable to the PC100

5.Connect the other end of the serial cable to an open COM port on your computer. All serial ports are raised pin (male) connectors

Connecting Terminals via RS-485

When selecting your installation method, the type of wire that will be used is important. Silver Satin (Modular) cable can be used for short distances less than 100’ to achieve communications. Category-3 or Category-5 cable with twisted pairs should be used for distances greater than 100’, in installations using J-Kits or in areas where the cable may run near a device that transmits an RF frequency. Do not use J-Kits with modular wire

For details, see the Cable Wiring Diagrams appendix.

The Swift-485+ allows you to connect PayClock terminals to the modular ports and to the screw terminal blocks. You can use either of the screw terminal blocks to connect the PC2000, PC100-R or PC3500 terminals. The PC100 / PC2000 modular port is set up to use with the PC2000 and PC100-R terminals. The PC2500 modular port is set up to use with the PC400 terminals (not currently available). The RS232 connection to the PC is made simple using a stereo type plug in jack.
