4.9 Error/Configuration Word
If the module is configured correctly, the configuration error word should have a
value of zero. Any other value indicates a configuration error. Use the value in
the configuration error word to determine which set of parameters are invalid in
the driver configuration area. The following table lists the bits associated with
each configuration error in the word:
Bit Code Description
0 0x0001 Invalid Cfg_type
1 0x0002 Invalid Cfg_Baud
2 0x0004 Invalid Cfg_Parity
3 0x0008 Invalid Cfg_DataBits
4 0x0010 Invalid Cfg_StopBits
5 0x0020 Invalid Cfg_Handshake
6 0x0040 Invalid Cfg_RTermcount
7 0x0080 Invalid Cfg_RPacketLen
8 0x0100 Invalid Cfg_RTimeout
9 0x0200 Invalid Cfg_RDelay
10 0x0400 Invalid Cfg_WTimeout
11 0x0800 Invalid Resv_Bit11
12 0x1000 Invalid Resv_Bit12
13 0x2000 Invalid Resv_Bit13
14 0x4000 Invalid Resv_Bit14
15 0x8000 Invalid Err_ROverflow
4.10 Cable Connections
The application ports on the MVI56E-GSC module support RS-232, RS-422, and
RS-485 interfaces. Please inspect the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.
Note: When using RS-232 with radio modem applications, some radios or modems require
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the UseCTS parameter to 1.
4.10.1 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
