DIP Switch/Jumper Setting
The DIP switch/jumper on the SMR10/20 readers are used to select a preset
format. This preset format determines how the card is interpreted, the functions
for the LED and buzzer, and the output signal format, etc. Refer to the format
specification for detail. The settings are for STANDARD models ONLY.

SMR10/20 Standard Format Code Summary
The following formats are supported in standard models (300x2-0000/310x2-0000).Unless otherwise indicated, the LED input
line controls both LEDs (low=green, high=red); the BUZZER input controls the buzzer (low = activate); a good read is signaled
by a flash of the green LED; a bad read is signaled by a flash of the red LED and a double beep of the buzzer.

0
32-bit Wiegand compatible output from standard
Northern Computer mag card. 16-bit facility code and
16-bit user ID. Reverse read and error filter is enabled.
Tamper monitor disabled.
1
Basic mag-stripe data output: send track 2 data without
any verification or formatting using CLOCK/DATA
signaling. (All reads are “good”, card data is sent as is.)
Tamper monitor disabled.
2
Mag-stripe data output with zero trim using CLOCK/DATA
signaling. (All reads are “good”, trims excess zero bits,
otherwise sends data as is.) Tamper monitor enabled.
3
Mag-stripe data output with zero trim, reverse read
correction, and error filter enabled using CLOCK/DATA
signaling. Tamper monitor disabled.
4
26-bit Wiegand (8-bit fac. and 16-bit ID) compatible
output from cards with 8 or more digits or AMC
encoding. See
Digit Usage
on page 3 for more
information. Tamper monitor disabled
5
34-bit Wiegand (12-bit fac. and 20-bit ID) compatible
output from cards with 8 or more digits or AMC encoding.
See
Digit Usage
on page 3 for more information. Tamper
monitor disabled.

Description
6
26-bit Wiegand compatible output from standard
Northern Computer 32-bit mag-stripe card. The lower 8
bits of the 16-bit facility code is used as facility code. The
16-bit user ID is unaltered. Reverse read and error filter
is enabled. Tamper monitor disabled.
7
Mag-stripe data output with zero trim and reverse read
correction using DATA 1/DATA 0 signaling. Tamper
monitor disabled.
12
Mag-stripe data output using CLOCK/DATA signaling.
2-wire LED control. No buzzer control. Tamper
monitor disabled.
13
Mag-stripe data output using DATA 1/DATA 0 signaling.
2-wire LED control. No buzzer control. Tamper monitor
disabled.
15
(factory test) mag-stripe data output: verify track 2 data
and send track 2 data without formatting using CLOCK/
DATA signaling. Zero trim, reverse read, bad card filter,
and tamper monitor option are enabled.
