USB CONNECTION
CONNECTIONS
The connection to the 2128L is either via Bluetooth
®
or USB. Bluetooth
®
connections use either a Virtual Com
Port (VCP) or via the iAP protocol for supported Apple iOS Devices. Over USB only VCP is available. For VCP the
connection is established at 115200 baud, 8 data bits, no parity, 1 stop bit and RTS/CTS (hardware) flow control.
CHANGING THE USB OPERATING MODE
The factory default mode for the 2128L ePop-Loq
®
is Charge-and-Data.
The
TSL Reader Configuration App can be used to switch the USB operating mode in an easy manner.
Alternatively, the USB operating mode may be changed by adding commands to an AUTO.TXT file placed in the
root directory of a Micro SD card in the reader.
Set USB mode to Charge-and-Data:
1. Create a blank AUTO.TXT file.
2. Add the following command to the AUTO.TXT file (without quotation marks):
“.fd -ep cd”
3. Place the AUTO.TXT within the the root directory of a Micro SD card in the reader.
4. Restart the reader
N.B. The ePop-Loq
®
USB mode is non-volatile and the command may be safely removed from the AUTO.TXT file
after it has been run once.
USB OPERATING MODES
The ePop-Loq
®
on the 2128L can be configured in one of two modes – Charge-Only or Charge-and-Data. Please
ensure the mode required is correctly configured.
● Charge-Only mode: Both the 2128L UHF Reader and the mounted device will be charged when docked in the
charging cradle, but will never use the USB data connection.
● Charge-and-Data mode: Compatible devices will use the USB data connection when not in the charging cradle.
Note that USB data connection to the 2128L requires a custom application that supports the TSL® ASCII
protocol over USB.
N.B. The USB connector on the charging cradle is always available when the 2128L is docked.
Set USB mode to Charge-Only:
1. Create a blank AUTO.TXT file.
2. Add the following command to the AUTO.TXT file (without quotation marks):
“.fd -ep co”
3. Place the AUTO.TXT within the the root directory of a Micro SD card in the reader.
4. Restart the reader
