Reader Status Request. Use this command to interrogate the reader about its operational
status. Two bytes of status information will be returned. ICC Power and Card Seated bits refer
to the currently selected card connector. Card Seated is only meaningful for the User
Connector. See Tables 7 & 8 for an interpretation guide for these bytes.
LED Commands. Use these commands to manipulate the LEDs on the reader (Firmware Beta
2.22 & later has flashing mode).
Select Card Connector. The Model 152 supports up to 9 card connectors. This command tells
the reader which connector is to be used with succeeding Card I/O Commands. The User
Connector (the only one the user can see) is number 0, and is always selected after a power
cycle. The Local Sam (GSM connector) is number 1. The remote SAM box contains up to 7
more connectors, numbered 2-8. The byte following the command byte codes the Connector
number.
Memory Card Type Select. This command is used to specify the type of Memory Card to be
accessed through the User Connector. The byte following the command byte codes the card
type. Table 4 shows the card types, type 0 is the factory default. The default type (always in
effect after power up) is selectable via the configuration program. By using type 0, a read of the
first four bytes (0-3) will always give the ISO 7816 defined ATR for synchronous cards if the
card in the connector conforms to the ISO standard. A user may be able to use the information
in the ATR to determine card type.

Configuration Request This command is used to obtain a configuration response which gives
details of the current configuration in the reader. See Table 9 for format and interpretation of the
response.
Switch Report. This command will return a “p” (hex 70) if no card is inserted or “s” if a card is
inserted. In automatic response mode the reader will send either “p” or “s” whenever the state
of the switch changes (Firmware Beta 2.22 & later).
