nHandle |
SHORT |
Handle to a GX6062 board. |
nGroupAOrL |
SHORT |
Specified either first or last group number, group number can be 0 (GX6062_GROUP_FIRST) or 11 (GX6062_GROUP_LAST). |
pnStatus |
PSHORT |
Returned status: 0 on success, negative number on failure. |
The first Group (GX6062_GROUP_FIRST) and the last group (GX6062_GROUP_LAST) have an additional really. Both relays are connected to the output connector (P61 and P62). The relays enable the first and/or last groups to be connected to an External Coax cable. This connection enables either a Daisy Chain connection to other GX6062 boards or to make a Loop Back through the Factory install a Loop Back Coax Cable.
Using the default Factory install a Loop Back Coax Cable enable a short path connection between groups, e.g. connecting group 2 and 10.
Use the Gx6062ConnectGroupToExternalCoax function in order to connect a group to the External Coax.
See the Gx6062ConnectChannels and Gx6062DisconnectChannels functions for details.
The Gx6062GetChannel function can be used to retrieve the current channel state.

Caution: 1. Make sure that the switching will not cause a closed loop, which may cause distortions in high frequency signals. 2. When closing a relay, verify that all other relays on the same circuit that may cause a short are disconnected (a delay may be required between switching commands). Low Impedance sources such as power supplies may cause irreversible damage to this product when shorted to other signals. |
The following example disconnects the last group to the External Coax:
SHORT nStatus;
Gx6062DisconnectGroupToExtCoax (nHandle, GX6062_GROUP_LAST, &nStatus);
Gx6062ConnectGroupToExternalCoax, Gx6062ConnectChannels, Gx6062DisconnectChannels, Gx6062Open, Gx6062SetGroupRelays, Gx6062GetChannel, GxSWGetErrorString
