2G HD over IP Dealer Support Manual – Page 4
Simple Type 1 Serial Communications using RS232 over IP ports
The 2G's have been shipped with the RS232 ports set for Type 1 ASCII mode. There is also a Type 2 BINARY
mode option, but that is a bit more complicated (more on BINARY mode later). In order to "connect" a
Transmitter RS232 port to a Receiver RS232 port in ASCII mode you do the following:
1. Enter client access mode by sending the byte "0x0E" (Ctrl-N, aka hex 0E ) to the Transmitter RS232 port.
This will break an existing link to another Receiver.
2. Link to the Receiver Mac Address with the ASCII Terminal Connect command (ast_c). The Receiver Mac
Address is shown on the TV status screen in the lower right hand corner as CLIENT ID. Baud rates up to
115200 are supported.
a. ast_c <macaddr><baudrate><break code override><enter>
b. For example, if your Receiver Mac Address is ABCD12345678 and you are wanting a typical
9600, 8, N, 1 connections you would issue the command
ast_c ABCD12345678 9600-8N1 [ENTER]
c. In the example below we see a HyperTerminal session where I used 2G RS232 Over IP to
connect to my Netgear switch RS232 port and issued the SHOW VLAN command.
