Recognition Systems HandKey II - Erasing Hand Reader Memory

HandKey II Installation and Operation Manual
Revision 2.0 Page 35
Communication Method
Communication can be done via an RS-232 direct connection, a 4-wire RS-422
network configuration, or a 2-wire RS-485 network configuration connected to a DC-
103 Data Converter. The factory default setting is for network communication via 4-
wire RS-422 cabling – switch 3 OFF. Refer to Figure 3-11 for switch ON/OFF
positioning.
• For network communication via 4-wire RS-485 (RS-422) cabling, switch 3 must
be OFF.
• For network communication via 2-wire RS-485 cabling, switch 3 must be ON.
• For network communication via direct connection, the switch 3 position does not
apply. Leave switch 3 in the default OFF position.
All Hand Readers in a network must be set to the same communication method. Four-
wire RS-422 cabling is required for HandNet for Windows™ network installations.
Recognition Systems does not recommend two-wire RS-485 cabling for new network
installations.
Erasing Hand Reader Memory
The erase memory function allows a Hand Reader’s setup and/or user database to be
erased. The factory default setting (and normal operation setting) is for switches 4 and
5 to be OFF, retaining memory.
Erasing the Hand Reader Setup
Perform the following steps to erase the setup programs but retain the user database.
1. With system power OFF, set switch 4 ON.
2. Turn system power ON and wait 5 seconds.
3. Turn switch 4 OFF.
Erasing the Hand Reader Setup and User Database
Perform the following steps to erase both the setup programs and the user database.
1. With system power OFF, set both
switches 4 and 5 ON.
2. Turn system power ON and wait 5 seconds.
3. Turn both
switches 4 and 5 OFF.
Before putting the hand reader into service ensure DIP switches 4 and 5
are both
OFF. If switches 4 and 5 are not off, the next time the Hand
Reader’s power is cycled the Hand Reader’s memory will be erased.
