Appendix G – Protocol Converter for Multiple POS
Multiple POS devices can be connected through the RS-232 port of the DVR. Please
refer to
Section 3.2 Optional Connections for the connections. Please refer to page
22/23 of 7524 Hardware User’s Manual for the pin assignment of I-7523, which is similar
to protocol converter I-7524.
Please note that the RS-485 module address of the protocol converter must be 1, 5, 9 or
13(Hex 0D), and the addresses of the POS devices connected are 1/2/3/4, 5/6/7/8,
9/10/11/12, and 13/14/15/16 respectively. The corresponding cameras for POS device
addresses 1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16 are cameras
1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16.
The default RS-485 module address of the protocol converter is 1. If the user wants to
change the RS-485 module address of the protocol converter to 5/9/13, please do the
following steps:
1. Connect the protocol converter to the RS-485 network of a host PC. (Please
refer to page 9 in I-7524 Software User’s Manual. RS-232-to-RS-485 converter
can be used in place of 7520.)
2. Execute 7188X.EXE in the host PC. (Please uncompress the file
\Napdos\MiniOS7\utility\7188xw_20050127.zip in the bundled 7000/7188/8000
CD to get the executable.)
3. Select the active COM port of the host PC by pressing Alt-1 for COM1 or Alt-2
for COM2.
4. Change the baud rate to 38400 by pressing Alt-C first, then enter b38400 to set
baud rate to 38400.
5. Change to Line-Command-Mode by pressing Alt-L.
6. Change the RS-485 module address by entering $01AXX. (01 is the original
module address, XX is the new module address such as 01/05/09/0D.)
Please note that the other settings for the protocol converter are Baud Rate = 38400, Data
Bit = 8, Stop Bit = 1, and Parity = None. Those settings cannot be changed, and have
nothing to do with the RS-232/422/485 Setup (which is related to the settings of the POS
printers connected).
